Cancer At The Cellular Level

Cancer cells are easy to kill using drug therapy however, they are hard to kill without damaging normal cells. This is because cancer cells rely on processes that are fundamentally similar to the processes used by normal cells. Their differences are in activity, not function. It is like two clocks one that keeps the right time and one that is fast. Both clocks use the same mechanisms, but one works at a higher speed. Any treatment that harms the structure of the fast clock, when given to the normal clock, would harm its structure as well. Regarding the cellular level then, the best way to inhibit a cancer cell (and to spare normal cells) is not to destroy its structural properties but to normalize the signals that drive it. These signals derive from its genetic instability, abnormal expression of genes, abnormal sig Part I is about these first four clusters and the natural compounds that inhibit them. Chapter 2 discusses the workings of DNA, the role of transcription factors in gene...

Why consider fatigue in cancer

In Western societies one in three people will experience cancer at some point in their lifetime, and one in four will die from it (Higginson 1997). In England and Wales there are 220 000 new cases of cancer per year, and around 140 000 deaths from cancer. Cancer accounts for around 22 of all deaths within developed countries and 9.5 of deaths within developing countries (Stjernsward and Pampallona 1998). In the future cancer is predicted to increase worldwide, with cancer of the lung, trachea and bronchus alone rising to the fifth most common form of death globally in 2020 (Murray and Lopez 1997a,b, 2000). In 2015 predictions estimate that almost 14 of deaths in developed countries and around 28 in developing countries will be due to cancer (Stjernsward and Pampallona 1998). Cancer affects people of all ages, from children and adolescents through to the very old, although most people who suffer cancer are in the older age groups, over 65 or 75 years of age (Higginson 1997). Cancer is...

Normal Cells and Cancer Cells

Normal cells and cancer cells are different in several ways. Normal cells reproduce themselves exactly and stop reproducing when they are supposed to. They self-destruct when they have completed their job or if they become damaged. Cancer cells keep on reproducing and do not obey signals to stop. A human colon cancer cell undergoes mitosis (division). Unlike normal cells, cancer cells do not die, but continue to divide. They have been called immortal because they refuse to die on their own. Normal cells stick together. Cancer cells do not, which allows them to become detached from their neighboring cells. Finally, normal cells mature and become specialized in doing their job. Cancer cells remain immature and even become more immature or primitive over time they do not perform any helpful function in the body.

How important is fatigue in cancer

Fatigue is important for patients with cancer at all stages of their illness, for some at diagnosis and for many during treatment. It occurs 80 to 99 of those receiving chemotherapy, radiotherapy, or both (Curt et al. 2000) and in 20 to 90 as the disease progresses. In the last week of life it is the most common symptom (Coyle et al. 1990 Edmonds et al. 1998 Connill et al. 1997). These variations in prevalence exist because epidemiological information about cancer fatigue is often poor. A previous lack of a consensus around the definition of fatigue and very varied methods of detection, assessment, and monitoring of fatigue, as well as the different populations studied, means that very different levels of fatigue are reported.

Cancer Genes as Potential Targets of Therapeutic Gene Silencing

Cancer is a genetic disease, arising from the cellular accumulation of genetic alterations, which enable the cells to evade their usual growth control 6 . These cells have the ability to spread and grow in distant sites or to propagate indefinitely and can be fatal for the individual organism in which they occur. There are several sequential steps which are necessary for the development of a tumorigenic phenotype, where selective proliferative advantages are gained, transforming normal cells into cancer cells 7 . The types of genetic alterations that can occur are described below.

Breast Cancer Biology And Behavior

There is growing understanding of the importance of the interactions between cells, and between cells and the surrounding stro-mal environment. Breast cancers frequently exhibit altered cell adhesion molecule expression, have altered matrix protein expression, changes in the cellular components of the tumor microenvironment, and extensive remodeling of the stroma. Chapter 5 focuses on key changes in cell adhesion molecules and stromal components, which have been shown to modulate breast cancer cell function, the potential for such features to act as prognostic and predictive factors for behavior, and the opportunity to use such alterations as therapeutic targets. p53 is well recognized as 'guardian of the genome', and alterations to the gene are common in cancers, including breast cancer. The precise clinical importance of p53 in breast cancer as a prognostic factor or predictor of disease response remains controversial and is discussed in Chapter 12, which concludes that substantial...

Cancer At The Level Of The Organism

Part II focuses on the procancer events that occur at the level of the organism and the natural compounds that may inhibit them. These events, which consist of interactions between a population of cancer cells and the body, fall into three primary clusters events that facilitate angiogenesis, invasion and metastasis, and immune evasion. In Chapter 7 we discuss the basics of angiogenesis, the growth of new blood vessels. These vessels provide the cells of a tumor not only nutrition and oxygen but also access to the circulation, thereby allowing metastasis. Natural compounds that inhibit angiogenesis are discussed in Chapter 8. In Chapters 9 and 10 we turn our attention to cancer invasion the spread of cancer cells into adjacent areas and metastasis the spread of cancer cells into distant locations via the blood or lymph. We then consider the immune response against cancer, discussing the basics of the immune system in Chapter 11 and natural compounds that affect it in Chapter 12. As in...

Cancerabnormal cell division

Cancerous diseases are characterised by the growth of abnormal cells that invade surrounding tissues and metasasis (the spread of cancerous cells to other parts of the body). Tumours may be cancerous and sometimes fatal, or they may be quite harmless. A cancerous growth is called a malignant tumour and a non-cancerous growth is called a benign tumour. Benign tumours do not spread to other parts of the body but they may be removed if they interfere with a normal body function or are disfiguring. Cancers are classified according to their microscopic appearance and the body site from which they arise. The name of the cancer is derived from the type of tissue in which it develops. Most human cancers are carcinomas, malignant tumours that arise from epithelial cells. Melanomas, for example, are cancerous growths of melanocytes, the skin cells that produce the pigment melanin. Sarcoma is a general term for any cancer arising from muscle cells or connective tissues. For example, osteogenic...

Similarity Of Angiogenesis In Wound Healing And Cancer

Wound healing is a normal process we are all familiar with, and the factors that stimulate angiogenesis in wound healing and cancer are the same.23 Indeed, the surgical wounding of tissues next to implanted tumors has been reported to increase tumor growth and angio-genesis in mice.24 In addition, wound fluid itself stimulates tumor angiogenesis as well as cell proliferation in vivo.23 Angiogenesis during wound healing and angio-genesis during cancer are so similar that some researchers have described cancer as a wound that will not heal. 2526 Not surprisingly, one study observed that when tumor cells were implanted into injured tissue in rodents, normal wound healing was inhibited, and an open, persistent wound developed that continued to form blood vessels.23 The primary difference between tumor angiogenesis and wound angiogenesis is that the former is driven by abnormal signals and continues unabated,

Future targets in pancreatic cancer

Because attempts at improving survival in pancreatic cancer with cytotoxic and biologic therapy have been modest at the most thus far, newer strategies of targeting the core signaling pathways implicated in pancreatic cancer are needed. Previously, genetic mutations affecting genes such as TP53, KRAS, CDKN2A and SMAD4 were known to be associated, but a more recent genome-wide analysis has identified a broader range of aberrant pathways implicated in pancreatic cancer growth. 46 In most of the 24 cancers examined in this series, the majority of the genetic mutations were felt to be disrupting one or more of 12 core signaling pathways. In pancreatic cancer, aberrations can occur in signal transduction and other pathways that promote cell survival and allow proliferation. These include KRAS, 47 PI3K Akt mTOR, 49-50 EGFR, 52 insulin-like growth factor (IGF-1) (which is co-expressed with Src), 52 hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF). 53 There are...

Prevalence how common is fatigue in cancer

The simple answer to this question is 'very'. However, there are a number of important obstacles to determining the prevalence of fatigue in cancer patients. In part it is difficult to gain a reliable picture of the prevalence of fatigue in cancer because most studies which look at fatigue in cancer assess the symptom in special groups. Table 1.1 describes some of the factors which might lead to variation in rates of fatigue in cancer patients. It is likely that the prevalence of fatigue in cancer patients varies significantly according to site and type of cancer, stage of disease, presence of medical co-morbidity (anaemia, infection, metabolic disturbance), and psychiatric disorders (especially depression and anxiety). Table 1.1 Factors likely to affect the prevalence of fatigue reported in cancer patients Table 1.1 Factors likely to affect the prevalence of fatigue reported in cancer patients Site of cancer Type of cancer Medical complications of cancer anaemia, infection, metabolic...

Prostate cancer in the world

Cancer is an important public problem and is considered a national health priority area in several countries due to the burden that it places on the individual, families and the community 1, 2, 31 . The World Health Organization (WHO) develops strategies towards the prevention, research, education and control of the cancer. Important medical developments and relevand scientific findings have permitted that people with cancer can survive with their disease and with the side effects of their disease and its treatment for longer 31 . The high relevance of the cancer in public health and research activity can also be demonstrated by the number of scientific research identified in the database system PubMed (a service of the National Library of Medicine and the National Institutes of Health) 32 . It is possible to see in the Table I, the number of publications in the PubMed related to cancer and cancer and some organs. It is possible to identify in the Table I approximately 2 700 000 full...

Risk factors for fatigue in cancer

If fatigue is strongly related to cancer, are there other risk factors among cancer patients which predict who is most likely to suffer from fatigue The literature here Table 1.2 Key studies assessing prevalence of fatigue in cancer patients Table 1.2 Key studies assessing prevalence of fatigue in cancer patients 913 cancer patients recruited by advertisements.

Cancerrelated fatigue and psychological distress depression and disability

Whereas physical markers of fatigue in cancer patients have been difficult to demonstrate consistently, the evidence for an association with depression and anxiety (reviewed in Chapter 10) is overwhelming. Indeed, it is difficult to find studies which have measured cancer-related fatigue and any measure of psychological distress which do not report an association. Thus Fulton (1997) reported an association between fatigue and anxiety and depression measured on the Hospital Anxiety and Depression Scale (Zigmond and Snaith 1983), Irvine et al. (1994) and Cimprich (1999) found associations with low mood and fatigue, Schneider (1998) found an association with fatigue and depression on the Beck Depression Inventory (Beck et al. 1961) and Broeckel et al. (1998) showed a strong association between fatigue and common psychiatric diagnoses such as depression and anxiety. Other studies showed similar associations on a variety of measures (Smets et al. 1996, 1998a,b Akechi et al. 1999 Cimprich...

Adults Dealing with Cancer

Fred had been doing quite well, with his cancer officially in remission for quite some time. Lately, he had been having some pain in his abdomen, and he was beginning to feel worried that something might be seriously wrong. He called his doctor who ordered tests and a follow-up office appointment. Fred came to group a few days before the tests, openly expressing his fear and anxiety about a possible recurrence of his cancer. The group offered him, in this case, the group stone that had lived in this group for many years, serving the transitional object purpose. Group members passed the stone around, each person holding it for several minutes to pray, symbolically give it energy, or whatever form of supportive thoughts or feelings that member felt appropriate. Fred then took the stone with him when he had his tests and doctor's appointment, reporting later that the stone helped him remember all the others in group who had dealt with similar scenarios with success.

Proposed Model of Ovarian Carcinogenesis

Recent clinicopathologic and molecular genetic studies as previously discussed provide the basis for a more comprehensive model of ovarian carcinogenesis, which proposes that there are two main pathways of tumorigenesis, corresponding to the development of type I and type II tumors (Tables 2-1 and 2-2 and Fig. 2-1). Note that Figure 2-1. A simplified diagram of types I and II ovarian epithelial cancers. CIN, cervical intraepithelial neoplasia MPSC, micropapillary serous carcinoma SBT, serous borderline tumor. type I and type II tumors describe pathways of tumorigenesis and are not specific histopathologic terms. Thus, they are not designed to replace the conventional terminology in pathology reports. Rather, the proposed model provides another view to classify ovarian epithelial tumors that may have clinical or translational implications in studying ovarian cancer.

Cancer Causes Heredity or Environment

It has been established by experts that cancers can be familial, or inherited, or sporadic, occurring at random in the population. Although most tumors arise in people with no family history of the disease, there is good reason for researchers to study both causes. Damaged or mutated genes can be inherited. When doctors establish a patient's medical history, they ask about close relatives who have had cancer and what kind of cancer they had. Doctors know that some types of mutated genes can be passed from parents to children. They are aware that patients with a family history of certain cancers are more vulnerable to that type of cancer. But they also know that although patients with a family history of cancer are at higher risk, they are not destined to develop cancer. Sometimes cancers that occur in several family members are just coincidental. They might also be caused by something in the shared environment. Compared to tumors that occur sporadically, the actual number of cases of...

Sources of Evidence Linking Diet and Cancer

Laboratory scientists have known since the early twentieth century that various nutritional manipulations can influence the occurrence of tumors in animals. Despite this discovery of the relationship between diet and cancer in animals, widespread interest in the study of diet and cancer in humans did not develop until more recently when the large international differences in cancer rates were correlated with variations in dietary factors. In fact, investigators have found strong correlations between estimated per capita fat consumption and breast cancer rates internationally, raising the possibility that dietary fat may have an important role in the etiology of breast cancer. Other observations such as those demonstrating that migrating populations adopted, sooner or later, the cancer rates of their new host population strengthened the evidence that international differences were the result not of genes, but of noninherited factors, including diet. The study designs used to...

Cancer of the Head and Neck

Cancer of the head and neck can cause gum problems and excessive bleeding. If you have been treated with chemotherapy, you will notice that your gums will bleed easily and you may also be prone to infection. If you have been undergoing radiation treatment, you may find that your mouth is always dry. This condition is called xerostomia. Dry mouth can cause more plaque retention and make your teeth prone to decay, especially if your gums have receded to the point where the roots are exposed.

Small Intestine Cancer

Cancer of the small intestine is very rare the age-adjusted incidence is approximately 1.4 per 100 000 less than 2 of all gastrointestinal malignancies. The incidence of small intestine cancer is higher in Maori of New Zealand and There are four types of small intestine cancer, each with unique characteristics adenocarcinoma, carcinoid, lymphoma, and sarcoma. In Western developed countries, approximately 30-40 of small intestine cancer is adenocarcinoma, predominantly in the duodenum, and carcinoid and lymphoma occur more often in the jejunum or ileum, whereas sarcoma may develop anywhere in the small intestine. In developed countries, lymphoma is very rare and occurs more often in older people with relatively good survival. In contrast, in developing countries, lymphoma is the main type of small intestine cancer, and it occurs more often in younger individuals, anywhere in the small intestine, with poor survival. Hence, prognosis of small intestine cancer depends on the type,...

Concomitant prostate cancer screening in the patient preparing for an APR

Patients scheduled to undergo APR represent a patient population in which prostate cancer screening may be indicated. Most cases of rectal cancer are diagnosed after 50 years of age 17 , and are in the same age category of men at risk for prostate cancer diagnosis. However, the stage of rectal cancer should be taken into consideration when considering screening the same individual for prostate cancer Stage T1 and T2 rectal tumors treated with APR have a 90 5-year survival, while stage T3 and T4 tumors are generally treated with neoadjuvant chemotherapy and or radiation and generally have a 5-year survival of 50 and 25 , respectively 17 . Thus, prostate cancer screening in patients with advanced disease should be avoided. Terris and Wren previously described a prostate cancer-screening program for 19 consecutive men scheduled for APR for colorectal carcinoma with no history of prostate cancer 18 . Screening included serum PSA and DRE and those with suspicious findings underwent...

Metabolic Activation of Epigenetic Carcinogens

Since there is no common mechanism describing the action of epigenetic carcinogens, generalizations concerning the effect of metabolism on the activity of chemicals acting by a nongenotoxic mechanism are not possible. The activity of a number of epige-netic carcinogens is reduced as a result of metabolic activation, although in the case of one group of epigenetic carcinogens that produce renal tumors in the rat by binding to and preventing the degradation of a specific kidney protein, alpha-2-microglobulin, metabolic activation is required for carcinogenic activity. Compounds acting by this mechanism include isophorone and D-limonene, which are present naturally in many fruits. Similarly, a wide range of structurally diverse chemicals induce liver tumors in rodents due to their ability to induce the proliferation of hepatic peroxisomes. Food contaminants such as phthalate diesters, which leach out of packaging materials, fall into this category, although no naturally occurring food...

Carcinogenicity Tests Animal Bioassays

As the mechanism of carcinogenesis in both humans and animals is not well understood, the only acceptable procedure for determining whether a chemical is likely to be a carcinogen is the examination of experimental animals exposed to the suspect material under carefully controlled conditions. This procedure relies on the assumption that animals will behave in essentially the same way as humans to carcinogen exposure, i.e., the mechanism of tumor induction will be similar in both animals and humans. Mechanistically based, short-term tests for carcinogenicity prediction not involving experimental animals are still a distant and elusive goal. The basic approach for carcinogenicity testing involves administering the test material to two suitable animal species for a considerable proportion of their natural lifespan. Because of their small size and relatively short life expectancy, the rat and mouse are the species of choice, although the hamster is occasionally used. In the US, inbred...

Carcinogens as a Cause of Cancer

Most cancers are not the result of inherited abnormal genes. They are the result of environmental factors. Some carcinogens have been known and understood for a long time. Others are being discovered through current research. The research is difficult because many cancers develop from the combined effects of more than one carcinogen on the DNA. Carcinogens enter the body through the skin or through the nose, mouth, or other openings. Sometimes it is apparent that people who work at particular jobs tend to get certain types of cancer. Experts study chemicals or other substances these people encounter in their work. The first step is to test the suspect substance on laboratory animals such as mice or rats. If a large percentage of the animals develop cancer, the researchers go on to evaluate the effect of the substance on people. They do this by comparing a group of people who have been exposed to the agent to a group of people who have not been exposed. If the exposed group has a...

Relationship of cancerrelated fatigue with sideeffects and symptoms of disease and treatment

There is fairly consistent evidence from studies of varying methodological quality that fatigue is related to many of the symptoms that accompany the experience of cancer and its treatment (Smets et al. 1993 Winningham et al. 1994 Nail and Winnigham 1995 Richardson 1995a). Symptoms linked with fatigue in the patient with cancer include pain, nausea, dyspnoea, and sleep disturbances. Table 2.3 lists these symptoms and a selection of the correlation coefficients reported in the literature. This highlights that the extent of the evidence is far from plentiful. Correlations between fatigue and other symptoms have only been assessed in a limited number of studies and the strength of these is inconsistent. This is not surprising as there is little similarity in the operational definitions adopted when measuring these symptoms, or in the context in which they are being assessed. However, based on the existing evidence, a degree of convergence is demonstrated. Because it is not wise to infer...

Management of oesophageal cancer

Survival rates in oesophageal cancer are very poor (Clark et al. 2000) only 6 of patients with oesophageal cancer survive for five years following diagnosis. In patients with disease with no metastatic spread outside the oesophagus the five-year survival rate rises to between 15 and 20 . For disease confined to the oesophagus, surgery should be considered in fit patients. Surgery alone cures only 5-10 , but a combination of preoperative radiotherapy, chemotherapy and radical surgery is associated with five-year survival of 30-50 in selected patients. Approximately 90 of the patients have extensive disease at presentation in these, treatment is palliative and based upon relief of dysphagia and pain. Surgically performed palliative procedures include excision and reconstruction or bypass. Endoscopically directed tumour ablation using laser therapy or alcohol injection and insertion of stents are the major methods of improving swallowing. Palliative radiotherapy may induce shrinkage of...

Cancer Invasion And Metastasis

Cancer is a chronic and progressive disease characterized by growth deregulation, cellular dedifferentiation and invasion. Cancer is the result of an accumulation of genetic alterations Cancer Metastasis, Molecular and Cellular Mechanisms and Clinical Intervention, 73-119. 2000 Kluwer Academic Publishers. Printed in the Netherlands. tumour-suppressor genes (4, 5, 6, 7). However, the distinction between both categories of genes implicated in tumour development has vanished (8, 9, 10). Although there is little doubt that these genetic alterations are the momentum of cancer development, it is our opinion that host cells are crucial for invasion and metastasis (Figure 2). Therefore, we consider invasion within a micro-ecosystem in which there is continuous molecular cross-talk between cancer cells and host elements, together establishing the tumour. Host elements implicated are inflammatory cells, immunocytes, endothelial cells, fibroblasts, and extracellular matrix produced by them....

Substance Abuse And Cancer Treatment

On the one hand, NARCOTIC and psychoactive drugs have an important role in cancer treatment. Cancer patients have used Cannabis sativa (marijuana) to reduce the nausea associated with chemotherapy. LSD has been used in treating psychological disturbances associated with cancer. Although it was once feared that cancer patients would become addicted to opioids given for pain control, a recent study showed that of 11,882 cancer patients On the other hand, preexisting abuse of these same substances complicates cancer treatment. A history of substance abuse may shorten a cancer patient s life expectancy and undermine the effectiveness of palliative care. Ongoing substance abuse disrupts the patient s relationships with physicians and other caregivers. As of 2000, the National Cancer Institute has issued guidelines for the clinical management of cancer patients with substance abuse histories. These guidelines include evaluation and treatment of comorbid psychiatric disorders, evaluation of...

Detecting and Treating Cancer

Cie earlier a cancer is detected, the better a person's chances are of a full recovery. For many cancers, early treatment can prevent the cancer from growing, invading other organs, and spreading to other parts of the body. Unfortunately, cancer is not always easy to identify, since symptoms vary greatly and may be similar to symptoms of many other illnesses. Sometimes there are no symptoms at all. Before the mid-1950s cancer was called the silent killer. By the time they saw a doctor, most cancer patients already had advanced cancer that had spread to other parts of the body. Today, scientists are constantly finding new and better ways to detect, diagnose, and treat cancer. It is most important, however, for individuals to be aware of how they can help detect cancer at an early stage.

Child vs Adult Cancers

When cancer strikes children and young people, it affects them differently than it does adults. For example, young patients often have a more advanced stage of cancer when first diagnosed. While only about 20 percent of adults with cancer have evidence that the disease has already spread when it is diagnosed, 80 percent of children's cancer has already invaded distant sites at diagnosis. While most adult cancers are linked to lifestyle factors such as smoking, diet, or exposure to cancer-causing agents, the causes of most childhood cancers are unknown. Adult cancers primarily affect the lung, colon, breast, prostate and pancreas, while childhood cancers usually affect the white blood cells (leukemias), brain, bone, the lymphatic system, muscles, kidneys, and nervous system. While most adult cancer patients are treated in their local community, cancers in children are rarely treated by family physicians or pediatricians. A child with cancer must be diagnosed precisely and treated by...

QOL in Long Term Survivors of Breast Cancer

In total, 16 studies met our search criteria for breast cancer, all published after 1998. The studies are described in Table 1 and include our study,32 which will be discussed in greater detail following the general review. Quality of life was a primary outcome in all studies. Of the 16, five studies compared the QOL between breast cancer survivors and healthy or normal controls.4,41-44 Two of five also compared QOL outcomes between survivors who have experienced a cancer recurrence to those who have not.4,43 Three of the 16 studies compared QOL between breast cancer survivors receiving different types of treatment.2,45,46 Two of the 16 investigated the QOL between breast cancer survivors diagnosed at different ages47,48 another two studies compared QOL at time of diagnosis and follow-up32,49 and two more examined the impact of treatment on QOL.50,51 One study looked specifically at the role of ethnicity in QOL outcomes,52 while the final study examined the...

Longterm Effects Of Cancer Diagnosis And Treatment On Survivors Family Members

The literature on the effect of cancer diagnosis and treatment on family members is sparse.74 Of studies in this area, most have focused on the impact of cancer soon after diagnosis, during recurrence, or at the terminal phase of the disease.75-77 One study shows that partners of men with prostate cancer, generally from small convenience samples, report more distress than their sick partners, but also believe that their partners are more distressed. The only reviewed study of long-term prostate cancer survivors found that couples' health-related QOL was associated with marital satisfaction.61 Distress was inversely related to levels of family support. The men's focus of concern, on their sexual functioning (i.e., impotence), was not shared to an equal degree by their non-sick partners.78,79 The most relevant study included in our review focusing on family survivorship included families from 1 to 5 years posttreatment,80 thus making specific statements about the long-term effects of...

Future Study of Kinase Inhibitors in Treating Ovarian Cancer

Protein kinases are the largest superfamily of conserved genes in the genome, and many of the family members are implicated in human cancer development. The kinase genes participate in numerous and diverse signaling pathways affecting cellular growth, differentiation, adhesion, motility and survival all key characteristics of tumorigenesis. Essentially, all structural changes in protein kinases that lead to neoplastic transformation appear to deregulate (constitutively activate) protein kinase activity, providing an attractive target for therapeutic intervention (Table 2-6). For example, therapeutic molecules or proteins have been designed to aim directly Table 2-6.

Mechanisms in Cancer

Reliable and easy methods are available to determine the effect of ROS and reactive nitrogen compounds by HPLS-MS MS analysis, especially as regards attacks on macromolecules such as DNA (4). In cancer research, we distinguish between agents that modify the DNA and generate a mutation. Such materials or synthetic chemicals are called mutagenic and genotoxic. There are chemicals or situations that enhance the development and growth of cells exposed to genotoxins. It is important to discriminate between these two classes of chemicals based on the permanence of their effect, and the doses and chronicity of exposure (5).

Preventive measures that can reduce the cancer burden

Based on the experience gained so far, it is considered that a substantial proportion of the cancer burden worldwide could be prevented if adequately implemented community-based programs for early cancer detection and treatment, tobacco control, cancer-related vaccination (for liver and cervical cancers), and health promotion campaigns (American Cancer Society, 2002 Commission of the European Communities, 2009 WHO, 2009) (Table 3). Avoidance of cancer-causing substances in the global environment and in consumer products Table 3. Primary prevention measures (taken before any sign of a disease occures) known to deal with the reduction in total cancer incidence

Tea and Cancer Prevention

Mutations of the cellular DNA are a key step leading to cancer (5). Mutational events can be used as markers for environmental genotoxic products that might be possible cancer risks (32). This approach is effective in research on products that might have antimutagenic and, thus, likely anticarcinogenic effects. This method has been applied to study the effect of tea polyphenols from black tea and from green tea. It was found that both types of polyphenols decreased in a dose-related fashion the mutagenicity of different types of carcinogens (Table 3). In another series of bioassays, similar results were obtained, demonstrating the stability and reliability of these rapid tests in forecasting the chemopreventive potential of inhibitors such as tea extracts (Table 4) (33-35). Selenium potentiated the effect of green tea on the mutagenicity of 2-amino-3-methylimidazo- 4,5-f quinoline (36). Parallel to the effects on DNA-reactive carcinogens, tea inhibited the formation of cancer of the...

Mechanisms and models of cancerrelated fatigue

'Unknown' in this category are conditions or diseases where the origin of the fatigue is obscure (although this is changing rapidly), such as cancer, chemotherapy, radiotherapy, viral, and bacterial infections, postsurgery fatigue, and CFS. It is possible that these types of fatigue have at least some mechanistic features in common. The emerging body of cancer-related fatigue knowledge can be combined with findings from other related fields (particularly exercise and CFS) to generate several models for the aetiology of cancer-related fatigue. None of the models is complete, but each is presented as a plausible and testable model to suggest (and hopefully stimulate) further research on the aetiology of cancer-related fatigue. For each we state the basic hypothesis, the key evidence upon which it is based, and suggest approaches to testing.

Small Cell Lung Cancer SCLC

Small cell lung carcinoma (SCLC) accounts for 20 to 25 of all bronchogenic carcinomas and is associated with the poorest survival of all histologic types 6 . SCLC is most often a lesion of the central portion of the lung but is occasionally found in the peripheral portions 2, 7 . In contrast to other major types of lung cancer, SCLC is highly sensitive to both chemotherapy and radiation therapy, which results in initial significant improvements in the survival of patients with this disease but the overall results remain unchanged in the following years due to development of drug resistance and death of the patients 8 . Yun et al 9 observed that the age-adjusted incidence per 100,000 person-years (standard Poisson regression analysis) for small cell carcinoma was 0.5 (95 CI 0.2-1.4) for never smokers, 3.5 (95 CI 0.4-27.3) for former smokers, and 11.1 (95 CI 1.5-82.9) for current smokers.

Both generic- and cancer-specific HRQL measures have been administered to heterogeneous and homogeneous samples of cancer survivors. Tables 1-3 provide a comprehensive list of frequently used measures with specific symptoms and HRQL domains and are included to help the user begin to select appropriate instruments for their purpose. While most investigators' needs can be more or less met by several of the available instruments, these tables enable one to consider coverage of the concepts of interest in a planned research or clinical program. This is followed by a brief review of these measures and their measurement characteristics, such as reliability and validity. The majority of these measures have been used in survivorship studies. A small group of additional measures has not been frequently used with cancer survivors, but have been included because they measure important content areas that are relevant to the survivorship experience.

Dietary Fiber and the Etiology of Cancers Colon and Rectum

This is one long-standing association that has been surprisingly problematic. Early studies on native Africans who consumed an unrefined diet showed them to have a very low incidence of this cancer. Although subsequent studies have shown a negative association between greater fiber intake and lowered risk, it has proved to be relatively weak. Indeed, in one US study there was no real association between fiber intake and cancer susceptibility. Some of the loss of significance seen in this evaluation may reflect the lack of allowance for confounding variables. For example, in a 6-year follow-up of women, the association between low fiber intake and the incidence of colon cancer disappeared after adjustment was made for meat intake. In another study of men, low fiber intake was an independent risk factor for the incidence of adenomatous polyps during a 2-year follow-up period. Fruit and vegetable fiber has been consistently associated with a lower risk of colon cancer, but the...

Longterm Care For Cancer Survivors Inattention To Issues Impacting Hrql

Although health providers are taught measurement principles from the beginning of their clinical training (e.g., height, weight, vital signs), clinicians are not routinely taught how to measure patient-reported symptoms and health status across the cancer spectrum. Optimal cancer care throughout extended survivorship includes obtaining a complete picture of ones' physical and psychosocial health status however, assessment and subsequent communication about these issues in medical consultations is often limited.213-215 Oncology specialists may overlook symptoms due to training emphasis on cancer biology, productivity pressures, and a care reimbursement policy that offers incentives for procedures or drugs and disincentives for consultation time. Therefore, insufficient attention is paid to patient In 2005, the Centers for Medicare & Medicaid Services (CMS) conducted a 1-year demonstration project for cancer patients undergoing chemotherapy. CMS provided payment of 130 per encounter to...

Screening of prostate cancer

Prostate cancer is one of the three major cancer sites in men commonly occures after 50 years of age, with incidence progressively increasing in later decades of life. Only males with positive family history of a disease (at least one blood relative father, grandfather, or brother) are at a higher risk even in age before 50 (American Cancer Society Guidelines for the Early Detection of Prostate Cancer, 2011 ESMO Guidelines Working Group, 2011). Screening protocol include digitorectal examination (DRE) and PSA (prostate-specific-antigen) measuring in serum, in patients aged 50 years, in those who refer symptoms of prostatism and urinary tract disorders, or in those who require screening. The decision on whether or not to have a prostate biopsy (performed by transrectal ultrasound, TRUS) should take into account PSA parameters, such as free (f) PSA, fPSA PSA ratio, DRE findings, prostate size, patient age, comorbidities, patient values and history of previous biopsy (American Cancer...

Programs of early cancer detection

In a general sense, screening program means systematic examination of the defined target population at average risk for developing some hazardous disease or undesirable medical event, or using scientifically justified tests that are appropriate to be applied as a public health measure (Table 6). Screening is organised periodically and at a long run, with the clearly defined aim to reduce the population burden of a disease and its unfavourable effects on the national health care system and economy. All activities in the program are fairly planned in an advance and performed according to the up to date standards of a medical care, with external finance assured. They include several subsequent steps, from promotional and educational activities, to screening, and a referal of subjects tested positive for further diagnostics and treatment. In concern to cancer, the early detection program is tending to become a part of more comprehensivelly shaped national strategies for cancer control,...

Prostate cancer incidence will increase in future

Prostate cancer is already most frequently diagnosed cancer among men in the developed world. As a cause of death among males, it is second in the USA and third in Europe. Large increase in prostate cancer incidence in recent years is not only due to availability of PSA (biochemical marker, which is useful for screening purposes) and due to better awareness of doctors and population at large, but in large part also due to changes in population pyramid and increased life expectancy. As breast cancer, which is most common in females over 60 years of age, also prostate cancer is cancer of older people. For example, in Slovenia (which may be in health related issues regarded somewhere in-between developed western and less advanced other parts of the world), incidence of prostate cancer increased 50 from 2000 to 2011 14 . At the same time, population at main risk (males above age 60) increased 28 . Therefore more than half of increase of prostate cancer incidence can not be attributed to,...

Need for hormonal treatment of prostate cancer may not decrease in future

Despite facts about prostate cancer incidence, presented in section 4 and despite undeniable proof that population based PSA prostate cancer screening reduces mortality due to prostate cancer 16 , it seems some professional bodies, like U.S. preventive services task force 17,18 recently advised against screening. Further, among young UK general practitioners, during non-formal conversation, in year 2012, one can easily hear claims like PSA - oh I thought it is NOT for screening, it is only for follow up purposes, only for patients, who have diagnosis of prostate cancer already (personal experience). With this recent trend by policy-makers, it seems hopes of urologists, who treat prostate cancer patients, that we will in the future find only very few patients, who will present with stage of disease, where nothing else but hormonal treatment would be possible or hormonal treatment will become necessary during the course of their disease, are dispelled. As it seems focus of attention is...

Ovarian Cancer Prevention

Both chemoprevention and prophylactic surgery have been explored as methods of preventing ovarian cancer. Chemoprevention involves the use of drugs, vitamins, or other agents to avert or delay the development of or recurrence of a malignancy. Prophylactic surgery is performed to remove a normal-appearing organ in order to prevent the future development of a primary cancer from that particular site. These preventive pathways may be pursued in the general population or specifically in patients with a high risk of developing ovarian malignancies. To determine the appropriateness of preventive therapies, the benefits of avoiding malignancy in individual members of a population must be weighed against the costs of treatment to the entire population. The impact of averting a cancer event in part depends on the type of malignancy. Ovarian cancer is typically diagnosed at an advanced stage and is usually associated with worse overall survival than malignancies such as cervical cancer, for...

Hepatocyte Growth Factor And Met In Tumour Invasionmetastasis From Mechanisms To Cancer Prevention

Abstract Hepatocyte growth factor (HGF), a ligand for c-met proto-oncogene product of receptor tyrosine kinase, exhibits powerful motogenic and angiogenic activities. The utilization of the HGF-Met system in cancer cells confers invasive and metastatic potentials. HGF potently enhances dissociation of cells, cell-matrix interaction, extracellular matrix breakdown, invasion, and angiogenesis, all critical events in the metastatic cascade. Tumour-stromal interaction mediated by HGF, aberrant expression of Met, autocrine or mutational activation of Met are tightly associated with carcinogenesis and malignant progression in a wide variety of tumours. Notably, NK4, the four kringle-antagonist for HGF-Met signaling inhibited tumour invasion and metastasis. The possibility has arisen that an HGF-antagonist can serve as a new therapeutic strategy for treatment of cancer patients. In normal tissues, HGF supports dynamic tissue remodeling for regeneration and the clinical application of HGF for...

Support groups for children with cancer

Many pediatric hospitals have ongoing support groups for children with cancer. Often these are run by experienced pediatric social workers, who know how to balance fun with sharing feelings. For many children, these groups are the only place where they feel completely accepted, where most of the other kids are bald and have to take lots of medicine. The group is a place where children or adolescents can say how they really feel, without worrying that they are causing their parents more pain. Many children form wonderful and lasting friendships in peer groups. I went to Junior Candlelighters, which was very helpful. The gal who facilitated the group was a survivor of osteosarcoma and had had her leg amputated. Yet, she skied, she drove, she did everything. I always thought, If Patty can do it, I can, too. If she can live so well without a leg, I should be able to put up with having a cancer in my blood. All four of my kids have been going to the support groups for over seven years now....

Hgf In Cancer Invasion And Metastasis

While HGF exhibits multiple biological activities for remodeling and maintenance of tissues, HGF greatly affects behaviors of a wide variety of cancer cells. Biological activities of HGF on various types of cancer cells are summarized in Table 1. Consistent with Met receptor expression in normal epithelial cells, HGF targets many types of carcinoma cells (tumour originating from epithelial cells), whereas aberrant expression of the Met receptor has been noted in tumours originating from mesenchymal cells and hematopoetic cells. HGF is involved in malignant behavior of these tumour cells and exhibits distinct biological activities on cancer cells, depending on the cell type. It is noteworthy that HGF has bi-directional effects on proliferation of cancer cells. Consistently, tumor cytotoxic factor, originally identified as fibroblast-derived cytotoxic growth inhibitor for some types of cancer cells, was shown to be identical to HGF (16). Particularly, HGF inhibits proliferation of about...

Cancer Prevention Studies

Some readers may be interested in the potential of selenium in cancer prevention as well as treatment. A number of studies have reported that low selenium levels are associated with increased cancer risk in hu-mans.52'53'54 Low levels have also been associated with increased risk of heart disease and reduced immune function.55 Associations with cancer risk appear to be particularly strong for breast, colon, and prostate cancers. Some examples follow, along with studies that suggest selenium supplementation can reduce cancer risk In a study on 321 subjects, 111 of whom later developed cancer, those with the lowest selenium levels were twice as likely to develop cancer as those with the highest levels. The association was strongest for cancers of the gastrointestinal tract and prostate.23 A cohort study of 33,700 men reported that prostate cancer risk was reduced in men who had higher dietary selenium intake.24 In a study on women over 50, high blood levels of selenium were associated...

Carcinogenesis and invasionmetastasis via activation of Met receptor

Establish the autocrine loop of the HGF-Met receptor Expression of HGF in Metpositive (but HGF-negative) epithelial cells, or expression of Met receptor in HGF-positive (but Met-negative) mesenchymal cells. When the HGF gene was stably expressed in a murine hepatic epithelial cell line, the cells showed a scattered phenotype, were capable of growing in soft agar and were tumourigenic in nude mice (152). Similarly, transfection of HGF in non-parenchymal liver epithelial cells resulted in establishment of the HGF-Met autocrine loop, and importantly, these cells exhibited invasive behavior and metastasized to the lung in nude mice (153). On the other hand, stable expression of the Met receptor gene in NIH 3T3 fibroblasts conferred tumourigenic and invasive characteristics in nude mice (154-156). Similarly, expression of the Met receptor gene in mouse 127 cells and human leiomyosarcoma cells resulted in establishment of the HGF-Met autocrine loop and concomitant progression from...

Nutrition for People with Cancer

People with cancer often have increased nutritional needs. As such, it is important for them to consume a variety of foods that provide the nutrients needed to maintain health while fighting cancer. These nutrients include protein, carbohydrates, fat, water, vitamins, and minerals. Nutrition suggestions for people with cancer often emphasize eating high-calorie, highprotein foods. Protein helps to ensure growth, repair body tissue, and maintain a healthy immune system. Therefore, people with cancer often need more protein than usual. Great progress has been made in the fight against cancer, and cancer detection and treatments have improved significantly. However, there is a disparity in cancer death rates between developed and developing countries. Between 80 and 90 percent of cancer patients in developing countries have late-stage and often incurable cancer at the time of diagnosis. A growing body of evidence shows that simple changes in diet and lifestyle can help prevent many...

Protective Effects Against Cancer

A 2001 critical review of the epidemiological evidence suggests a preventive effect for garlic consumption in stomach and colorectal cancers, but not other cancers (Fleischauer & Arab 2001). In regard to gastric cancer protection, case-control studies suggested a protective effect for raw and or cooked garlic when eaten at least once a week whereas protective effects against colorectal cancer seem to require at least two servings of garlic per week. A similar view was reported in a 2003 review by Ernst, which stated that the weight of evidence to support the use of allium vegetables, such as garlic, in cancer is clearly positive. Intervention study in colorectal cancer A preliminary double-blind, randomised clinical trial in patients with colorectal adenomas-precancerous lesions of the large bowel produced promising results with the use of high-dose aged garlic extract (AGE 2.4 miyday) (Tanaka et al 2006). The study of 51 patients measured the number and size of adenomas at baseline...

Aberrant expression of Met receptor in cancers

At least two distinct mechanisms by which the Met receptor is over-expressed in cancers could be considerable, i.e., transcriptional activation or amplification of the c-met gene. In case of colorectal cancers, over-expression of the Met receptor was related to transcriptional activation in 90 of the primary tumours, whereas 8 among 9 cases of metastases of colorectal cancers accompanied amplification of c-met gene (189). Amplification of the c-met gene may possibly occur more frequently in late stage metastatic tumours than in primary tumours, presumably due to chromosomal instability in advanced cancers. Table 3, Expression of Met receptor in cancers_ Colorectal cancer over-expressed higher in metastatic tumours 188, 189 Gastric cancer over-expressed and related to the increase in 62, 192 disease state over expressed and higher in diffuse and high grade invasive cancers Ovarian cancer Pancreatic cancer Prostate cancer Thyroid cancer expressed and higher in advanced cancers Figure 7....

The role of family physicians in programs of early cancer detection

In terms of organization, two extreme early cancer detection program forms are possible, either that supplied by governmental and public health institutions, or that based on the central role of family physicians in program s implementation. By working at the interface of the health care system and the population, family physicians are in the specific position that enables them an opportunity to promote a vast array of preventive activities, in a proactive and a patient-oriented manner (Summerton, 2002). That means that the doctor recognises medical needs of the groups and individuals, encourages them to take preventive measures and manages the screening protocols, in contrast to the approach where the doctor generally responds to the patient s requests. Moreover, the possibility of having an insight into specific characteristics of each patient, enables family physicians to select an appropriate way to present the preventive measures to a patient, and to create activities, in order...

Other Cancer Treatments

Researchers are constantly searching for better ways to treat cancer. Some of their discoveries have proven to be lifesavers. For example, leukemia was once considered incurable. Today bone marrow transplants give hope to thousands of leukemia victims. Immunotherapy works to use the body's own defense system to fight cancer. It uses substances designed to strengthen the patient's immune system and make it more effective in rec ognizing and attacking cancer cells. Vaccines are also used to stimulate the immune system. Interferons, chemical messengers used to fight viruses, inhibit tumor cells from reproducing. Hormonal treatments are also under study. Hormones are substances secreted by certain glands that pass into the blood and stimulate the action of specific organs. It has been shown that certain hormones made by the testes and ovaries can influence the growth of tumors in the breast and prostate. Today, instead of surgically removing the testes or ovaries, drugs are used to block...

Experiences from Croatia in involving family physicians in programs of early cancer detection

The leaders of the Department of Family Medicine of the Osijek University School of Medicine and the Health Center Osijek, have recently introduced the project A Model of Early Cancer Detection Integrated in Practice of Family Physicians , to test the idea that screening and early diagnosis of cancer are more efficient if integrated in practice of family physicians, compared to the National Program, centrally directed and supplied by the public services (Ebling Project, 2007, as cited in Majnaric-Trtica, 2008b). The Project has started after two years of preparations and education of subjects from the target groups and family physicians, included in the Project, on screening and early detection methods. The computer program, specifically designed for keeping the records on data and for follow up of patients with positive screening tests, was installed into a total of twenty GP offices included in the Project. This program has allowed the continuous recruitment of new patients into the...

Head and Neck Cancer 711 Epidemiology

Of Washington Quality of Life Scale86 and other quality of life instruments. The most common cancer sites were the larynx, oral cavity, oropharynx, and hypopharynx. Patients who underwent combined surgery and radiation had significantly worse scores for pain than patient treated with radiation or surgery alone (p 0.01) Patients who experienced pain or disfigurement were more likely (RR 2.18, p 0.05) to have concerns about cancer recurrence.87 In another survey of 135 survivors 3 years out who completed the SF-3688 and the EORTC QLQ C H&N 35,89 patient data was compared to population norms. The most common tumor sites were the oral cavity (40 patients), pharynx (35 patients), and larynx (28 patients). Overall SF-36 bodily pain was similar for the two groups. However, the cancer survivors were significantly worse compared to the population for the H&N35 scales for local pain, swallowing, senses, and social eating.90 In a study of 182 patients with nasopharyngeal carcinoma who had lived...

Cervical cancer and fertility

Cervical cancer can develop in women while they are still young and have not begun or finished having children. Because the cervix is part of the uterus, treatment of cervical cancer can mean that the uterus will have to be removed or that it will be exposed to radiation. Some early cervical cancers can be treated with a procedure (known as a trach-electomy) that removes the cervix but leaves the uterus in place. However, this approach is not always a possibility. It's important to have a discussion with your gynecologic oncologist about your desires for future childbearing before you begin treatment. If necessary, a referral can be made to a specialist in reproductive endocrinology and infertility. Obviously, the best way to preserve your fertility is to avoid radiation and to preserve your uterus, tubes, and ovaries, and as much of your cervix as possible. Unfortunately, with cervical cancer this often is not a realistic possibility. However, even if reproductive organs need to be...

Recent Quantitative And Qualitative Analyses Of Breast Cancer Plasma

With the now widespread availability of realtime qPCR a number of research groups have developed quantitative assays to determine the level of cell-free DNA in plasma and serum. These assays measure the concentration of a known gene (typically glyceraldehyde 3-phosphate dehydrogenase (GAPDH) Genbank Accession No. J04038) in either plasma or serum samples relative to a serial dilution curve starting with a known concentration of human genomic DNA. Gal et al21 analyzed serum samples from 96 patients with primary breast cancer and compared these to 24 healthy controls. The DNA concentration in the serum of the patients differed significantly from the controls. The medians were 221ng ml and 63ng ml of serum, respectively (p 0.001), and serum DNA levels were elevated in cancer independently of the size of the primary tumor or lymph node metastases. However, others have cautioned against the use of serum to monitor the concentration of cell-free DNA in a patient's circulation since most...

Implications for Cancer Therapy

In vivo, especially when single antioxidants are given. This, of course, is a drawback to using high doses in cancer therapy. An antioxidant effect is likely, however, if moderate to low doses of antioxidants are used, and they are used in combination. If antioxidants are used to produce an antioxidant rather than prooxidant effect, the antioxidant effect produced will generally be beneficial to the body. For example, immune cells may function better when they contain adequate antioxidants. Cancer cells may also benefit, however. Using antioxidants in cancer treatment is currently a matter of much debate, and it is especially heated regarding use of antioxidants in combination with chemotherapy. In theory, because many chemotherapy drugs act by generating ROS, anti-oxidants could reduce ROS-induced apoptosis in cancer cells. Indeed, several in-vitro studies have reported that antioxidants can protect cancer cells from ROS-induced apoptosis.167173 Moreover, in-vitro and in-vivo studies...

Hyposecretion in patients at risk of gastric cancer

Hpylori infection predisposes to distal gastric cancer, but patients who develop this complication have diminished acid secretion. Low acid secretion in gastric cancer was, until recently, thought to be predominantly due to gastric corpus gastritis, the associated gastric atrophy leading to loss of parietal cells. However, Hpylori associated acid hyposecretion can in part be reversed by eradicating Hpylori, suggesting that hyposecretion is due to inflammation rather than to permanent loss of cells. Hpylori associated acid hyposecretion may also be due to incomplete recovery from the loss of acid secretion that occurs with acute infection or may be in part genetically determined because it is more common in the first degree relatives of patients with gastric cancer. Low acid secretion predisposes to gastric cancer by several mechanisms, including impaired absorption of vitamin C and overgrowth of salivary and intestinal bacteria within the stomach. By contrast, proximal gastric cancer...

Cancer risk prediction models

The average risk of getting a cancer (for a 5-years, or a 10-years time period, or expressed as a lifetime risk) are estimated on the basis of the incidence data for the population. Many factors that can change these estimates to the higher or to the lower, for some of the most common cancers sites, have been identified (known as cancer risk factors) (US National Cancer Institute, 2010, 2011). Knowledge on this issue allows personalisation of risk assessments, based on the estimates such as the score charts, or mathematical risk prediction models, which can help physicians and policymakers to identify individuals who might benefit, more than some others, from the screening. Multivariable risk prediction models for some usual cancer sites have been established so far, based on using easily available epidemiologic and clinical data and identified risk factors. It has been realised, however, that the model s precision can further be improved, if some biochemical or molecular biomarkers...

Tight Junctions A Critical Structure In The Control Of Cancer Invasion And Metastasis

Its main function is to control the paracellular diffusion of ions and certain molecules. Although the structure has been known for decades, the molecular composition of the tight junction has only been recognised in the past decade. Molecules making up tight junctions include the transmembrane proteins occludin, claudin and paracellin, and cytoplasmic proteins, MAGUK family members. The structure has now been demonstrated as also having a role in the control of cancer cell penetration of the endothelium and in the development of cancer.

Principles of Cancer Screening

Screening is the application of a test to detect a potential cancer when no signs or symptoms of the cancer are present.5-7 Ideally, the cancer is detected before it is clinically apparent, when treatment may be more effective, less expensive, or both. If a screening test result is abnormal, a diagnostic test should be ordered and treatment pursued if cancer is discovered. The value of a screening test is compromised if symptomatic individuals are included in the target population, since those with symptoms may already have advanced disease that warrants a diagnostic evaluation. The gold standard for screening is the ability to decrease mortality from cancer. Therefore, the goal of ovarian cancer screening is to reduce mortality by detecting the cancer in earlier stages, when survival rates are improved. There are a number of general principles of effective cancer screening that must be applied to ovarian cancer screening Box 6-1. Characteristics of a Good Cancer Screening Test Box...

Challenges of Ovarian Cancer Screening

Developing an effective screening test for ovarian cancer in the general population poses many challenges. First, a distinct precursor lesion to ovarian cancer has yet to be identified. Therefore, ovarian cancer screening is limited to an attempt to detect early-stage disease. Initial laboratory data support a progression of early-stage disease to advanced-stage disease, which is important if screening is to be effective. Investigators have demonstrated that over 90 of sporadic ovarian cancers are clonal, and a similar pattern of abnormalities exists in high-grade stage I and stage III cancers.9-11 Investigators have also shown that up to 1.9 years may exist between the development of ovarian cancer and its clinical detection.12 However, the histologies of stage I ovarian cancer have a predominance of mucinous, clear cell, and endometrioid cancers, in contrast to advanced-stage disease, which has a predominance of serous cancers. In addition, population-based screening studies have...

Ovarian Cancer Screening in High Risk Women

In contrast to the 1.5 lifetime risk of ovarian cancer for women in the general population, women with a BRCA1 mutation have a 39 to 46 lifetime risk of ovarian cancer, and women with a BRCA2 mutation have a 12 to 20 lifetime risk of ovarian cancer3,4 (Fig. 6-8). Although prophylactic bilateral salpingo-oophorectomy (BSO) remains the mainstay of ovarian cancer prevention in these high-risk individuals, strategies for screening and early detection are important for high-risk women who have not yet chosen to undergo the surgical procedure or who are unwilling to do so. Given that the mean age of diagnosis of ovarian cancer in women with a BRCA1 or BRCA2 mutation may be 10 to 15 years earlier than 61 years the mean age of diagnosis in women with sporadic ovarian cancer screening strategies in the high-risk cohort need to be focused primarily on premenopausal women. This is in contrast to general population screening for ovarian cancer, which is focused primarily on postmenopausal women....

Anticancer Antitumor Effects

Lentinan would also be effective for patients with advanced or recurrent breast cancer (41,42). Side effects have been transitional and not serious. Use of lentinan in a combined treatment of patients with advanced or recurrent gastric or colorectal cancer has also resulted in an increased life span (26,43). In addition, lentinan was able to prevent chemical oncogenesis as shown by its suppressive effect on 3-methylcholanthrene-induced carcinogenesis (36). Past studies have shown that the efficacy of lentinan in the treatment of cancer is increased when used in conjunction with other therapies. The highest antitumor effect was achieved when bacterial lipopolysaccharide was used with lentinan (50,51). Lentinan could be used in combination with IL-2 for treating cancer (52-56). The combined administration of IL-2 and lentinan was effective against IL-2-resistant established murine tumors. Hamuro and co-workers (57) also investigated the antimetastatic effects of combined treatment with...

The personalised approach in early cancer detection the role of genomics and proteomics

The rapid progress in biotechnology has been expected to provide huge benefits in prevention and early detection of chronic noncommunicable diseases, notably cancer, by implementing genomics, proteomics and other -omics techniques in practice. The main principle, these techniques relies on, is a possibility of identifying subjects at an early clinical or subclinical phase, during the course of developing a chronic disease, by obtaining the whole-genome sequencing (genomics), or by characterising the protein and peptide profiles of various biological fluids or tissues (proteomics) (Yang, 2003, Khoury, 2007, as cited in Majnaric-Trtica, 2009). These techniques have attracted the attention of both, the scientists and the public as a whole, in recent times, for their potential to stimulate the adoption of the personalised approach in medical practice, with expectancies for the improvements, equally in prevention, prognosis, diagnosis and treatment. For the reason that these techniques...

Lay perceptions of cancerrelated fatigue an emergent model

The model outlined in Fig. 5.1 attempts to capture ways in which people assimilate cues that shape their dynamic experience of cancer-related fatigue as it changes with time and alternating cues. It endeavours to indicate how people's varied constructions in turn impact on their well-being and ability to respond to the challenge of living with cancer and its treatment. Furthermore it attempts to respond to and support Wenger's (1993) assertion that nursing's care agenda should be broader than an illness episode per se, taking account of an individual's day-to-day life concerns and associated cultural constructions, rather than limited to biomedically defined illness boundaries. Wenger suggests that research and practice directed at developing culturally sensitive care reflect the following guidelines (Wenger 1993, p. 27) Illness factors shaping lay constructions of cancer-related fatigue Physiological burden (e.g. type and stage of cancer, previous state of health, treatment and...

Bone Marrow Micrometastasis In Breast Cancer

Ninety-five percent of patients who present with breast cancer apparently have local disease without evidence of distant metastatic spread on pretreatment staging by conventional methods (1). Despite improvements in surgical techniques, radiotherapy and drug treatment, one third of all patients relapse and die within ten years, and this proportion has not changed significantly. It is accepted that this group of patients has micrometastatic disease at presentation that cannot be detected by current standard methods (2-5). Therefore, indirect prognostic criteria, such as lymph node metastasis, tumor size, and the presence of tumor emboli in lymphatic or vascular spaces associated with the primary tumor, are used in an attempt to identify a group of patients at high risk of developing distant metastases, who would perhaps benefit from adjuvant systemic treatment. Though axillary lymph node status in breast cancer patients remains the single most important predictor of outcomes, our...

Depression After Cancer Treatment

Upon completion of treatment, individuals with cancer are typically expected to resume the responsibilities, activities, and roles of daily life. At the same time they begin to separate slowly from the close monitoring that they were receiving during their treatment from health care providers. The result is that cancer survivors routinely report that they face a new set of challenges upon completion of cancer treatment, with some likening the experience to walking a tightrope without a net. With this degree of uncertainty, cancer survivors who have completed treatment continue to be at risk for depression. The prevalence of depression in this population, however, has been historically understudied. As with the previous stages along the cancer continuum, assessment of the general prevalence of depression after treatment has been made difficult by the various assessment methods and time at which depression is measured following treatment. Generally speaking, the incidence of depression...

Polyunsaturated Fatty Acids And Their Role In Cancer Invasion And Metastasis

Key words Essential fatty acids, gamma linolenic acid, eicosapentaenoic acid, cancer treatment, invasion, metastasis, cell adhesion, angiogenesis Abstract Highly unsaturated fatty acids (HUFAs) have been demonstrated to have anticancer functions in the past decade. Recently, these fatty acids have been shown to exert a regulatory action on tumour cell motility, invasion and metastatic behaviour via such mechanisms as regulation of cell-cell adhesion, tumour suppressor molecules and motility related signal transduction pathways, and angiogenesis. Clinical studies based on laboratory results have recently been carried out and early indications show promise in extending the survival of patients with cancer. The relationship between diet lipids and the incidence of cancer has been established. This is best demonstrated in Eskimos, who consume essential fatty acid (EFA)-rich diets and enjoy a low incidence of cancer (1). Similarly, other populations with high EFA intake also show a low...

Glutathione as an Anticancer Compound

Effect on cancer progression or could assist or inhibit it. Each of these results has been observed in animal studies. For example, in one study in rats, 5.3 grams per day, as scaled to humans, given orally caused partial or complete regression in 81 percent of established afla-toxin-induced liver tumors.41 In another rat study, oral administration of 2 g kg of glutathione inhibited growth of transplanted breast cancer cells tumor inhibition was associated with a decrease in PGE2 production, suggesting that intracellular concentrations of glutathione were increased.42 At least one animal study reported detrimental effects 500 mg kg of glutathione in the drinking water increased the size of chemically induced tumors in rats.43 In other animal studies, glutathione had no effect on tumor growth.44

The emotional experience of cancerrelated fatigue suffering

Mathieson and Stam (1995) have suggested that whilst classifications of psychosocial difficulties have been developed, this has not been translated into an exploration of what this means to cancer patients. Certainly, little attempt has been made in the studies reviewed, and the CRF literature in general, to try and account for these feelings and explain why they occur, except to try and establish whether anxiety and depression cause fatigue. Cassell (1992) has stated that for suffering to occur there must be a concept of the future. 'The future onto which suffering is projected must contain an idea of the person's identity and that must have arisen in the past and be cohesive from the past through the present and into the future' (Cassell 1992, p. 4). Conrad (1987) has identified cancer as a 'mortal' illness, that is one that threatens to rob people of their future by taking their life away. In the studies reviewed it was reported that participants interpreted their fatigue as a sign...

Correlates Of Relationship Functioning After Cancer

Given that the majority of cancer survivors describe high levels of relationship quality, the more interesting question from a psychological standpoint may not be how relationships change after cancer, but rather for whom they change and why. Such data are crucial to identifying individuals and relationships that may be at risk for maladjustment and developing intervention strategies to improve survivor outcomes in this domain. We now turn to addressing the medical, demographic, and psychological variables that may be associated with relationship outcomes following cancer. Virtually all of the available data address the couple or partner relationship, which will also be the focus of our review below unless otherwise noted.

Table 91 Factors Contributing to Cancer Related Fatigue

Destruction of normal cells along with cancer cells by treatment (repairing Reduction in blood counts by chemotherapy (anemia may occur as a result) Effects of medicines used to treat the cancer or alleviate side effects Chronic pain Stress working so hard to repair the damage to healthy cells and tissues. Other theories focus on the abnormal accumulation of chemicals in the body that may not cause problems normally but lead to fatigue when they are produced in large quantity. The normal nerve-to-muscle transmission, which prompts muscular contractions, may also be affected if certain other chemicals are not readily available. And there are other theories that suggest other potential factors in cancer-related fatigue (see Table 9.1). We do know that cancer-related fatigue can last for weeks, months, or even years following treatment. The type of cancer may be a factor as well as the treatment regimen. Nearly every oncology treatment, including biological therapy (for example,...

Is there a relationship between GERD and cancers of the head and neck

Cancer of the head and neck is the fifth most common cancer in the United States. The head and neck includes the mouth, tongue, nose, nasopharynx, sinuses, pharynx, tonsils, and larynx. The most common cancer site in the head and neck is the larynx or voice box. This accounts for about a quarter of all head and neck cancers. The greatest risk factor for head and neck cancer is smoking however, cancer of the larynx increasingly is being reported in patients who were lifetime nonsmokers. As previously discussed, reflux can affect the larynx (see Question 52). Long-standing acid damage to the larynx causes inflammation of the cells lining the larynx. Repeated damage and healing causes these cells to die off and reproduce themselves at a faster rate than normal. Because of this faster turnover of cells, there is a greater risk of damage to the DNA (the genetic code within the cells), which allows cells to become more and more abnormal as they reproduce and ultimately results in cancer....

Efas And Cancer Cell Motile Behaviour

The motility of tumour cells is required in the whole metastatic process (figure 2). The motility increases when cancer cells are stimulated by a number of motility factors (also known as motogens). These motogens are known to increase in hosts bearing tumours (85). The effect of PUFAs on tumour cell motility and motogen-stimulated motility has been recently reported. Figure 9A. Effects of GLA on the expression of maspin and motility of cancer cells. Human colon cancer cells were treated with different fatty acids (left), GLA at different concentrations (middle), or with GLA for different time periods. The level of maspin protein was determined using Wetern blotting. GLA increased the level of maspin . PUFAs and cancer metastasis Figure 9 continued.

Regulation of Cell Proliferation and Apoptosis Cancer Chemopreventive Activity

Since its reported cancer chemopreventive activity in a mouse model of carcinogenesis, there has been a flurry of papers reporting the effects of RSV on critical events that regulate cellular proliferation and growth. In this regard, biochemical pathways involved in differentiation, transformation, cell cycle regulation, and cell death induction have all been demonstrated as potential targets of RSV (Bhat and Pezzuto, 2002 Gusman et al., 2001 Joe et al., 2002 Soleas et al., 2001a). In the preceding sections describing the diverse signaling networks impacted by RSV, I touched on some of the intricate pathways operational in carcinogenic transformation of cells. These include intracellular generation of ROI, activation of protein kinases, induction of enzymes that generate proinflammatory mediators such as COX and lipoxy-genase, activation of transcription factors such as NF-kB, AP-1, CYP1A1, AHR, and p53, growth stimulation of estrogen-responsive cells, etc. As remarkable as it seems,...

Prediction Of Prognosis In Nodenegative Breast Cancer

Prognostic models for node-negative breast cancer that rely on tumor size and histological grade are useful but imperfect. At least two distinct gene-expression profiling-based tests were recently developed which may improve prognostic prediction for these patients. One of these - Mammaprint (Agendia Inc, Amsterdam, the Netherlands) - was recently cleared by the US Food and Drug Administration (FDA) to aid prognostic prediction in node-negative breast cancer, and it may become available commercially shortly. This assay measures the expression of 70 genes and calculates a prognostic score which can be used to categorize patients into good or poor prognostic risk groups. This test was evaluated on two separate cohorts of patients that received no systemic adjuvant therapy. The first cohort included 295 patients and showed that those with the good prognosis gene signature had 95 ( 2 standard error (SE)) and 85 ( 4 SE) distant metastasis-free survival at 5 and 10 years, respectively,...

What Is Successful Adaptation To Advanced Cancer

The extant literature on patients with metastatic cancer focuses almost exclusively on two indicators of psychological adjustment depression distress and QOL. Reports of the prevalence of emotional distress among individuals living with AC vary depending on the method of assessment and the nature of the sample.29 Several large studies and literature reviews estimate the prevalence of depression in AC to be approximately one-quarter to one-third of patients.29-35 Studies using self-report instruments generally report higher prevalence rates than those using structured psychiatric interviews to diagnose depression,29 and rates may be inflated if measures include somatic symptoms of depression (e.g., fatigue, insomnia).36 Estimates based on the perceptions of caregivers or physicians may also inflate the prevalence of distress, as one study based on palliative care social workers' assessments of patient functioning found that 63 of patients were anxious and 54 were depressed.28 In...

Cancer Prevention

High dietary intake of lutein has been associated with reduced risk of some cancers, most notably endometrial and ovarian cancer, but not all cancers, according to epidemiological evidence (Freudenheim et al 1996, Fung et al 2003, Gann et al 1999, Giovannucci et al 1995, Huang et al 2003, Ito et al 2003, Lu et al 2001, McCann et al 2000, Michaud et al 2000, Nomura et al 1997, Schuurman et al 2002, Terry et al 2002). Lung cancer The link between carotenoid intake and lung cancer has undergone extensive scrutiny and extensive epidemiological evidence suggests a reduction in lung cancer risk with high dietary intake of carotenoids (Cooper et al 1999). Initial research used food composition tables and therefore focused on beta-carotene, for which data was available however, the dietary intake of beta-carotene and other carotenoids such as lutein and zeaxanthin are highly correlated (Ascherio et al 1992) and as food composition data for these nutrients has become available studies have...

Potential Carcinogenic Effects of Flavonoids

Since flavonoids can produce a prooxidant effect in-vitro (see Table 15.3), their ability to induce cancer has been of concern. Quercetin has been of most concern due to its high redox activity of all the flavonoids it produces the greatest mutagenetic effects in vitro, as discussed previously. When quercetin is used with a carcinogen, it can increase carcinogen's effects (in this situation, quercetin acts as a tumor-promoting agent). For example, it enhanced the carcinogenic activity of 3-methylcholan-threne in mice and azoxymethane in rats.105,106 In the first study, quercetin was only active when it was co-injected subcutaneously with the carcinogen in the mice, and therefore these results have little relevance to oral administration. In the second, perhaps more relevant study, an oral dose of about 1.3 g kg combined with the carcinogen decreased development of breast cancer in rats but increased that of colon cancer. It is reasonable to suppose that the very high concentration of...

Anticarcinogenic Activities and Synergistic Effects in Combination with Chemical Therapeutic Agents

Several investigations were carried out to evaluate the inhibitory or preventive effects of ginseng on carcinogenesis induced by various chemical carcinogens. The prolonged administration of Korean red ginseng extract inhibited the incidence and the proliferation of tumors induced by 7,12-dimethylbenz (a) anthracene (DMBA), urethane, and aflatoxin B1 (57). The chemopreventive potential of ginseng was evaluated using DMBA-induced skin tumorigenesis (papillomagenesis) in male Swiss albino mice. There was a marked reduction not only in tumor incidence but also in cumulative tumor frequency at the initiation phase of tumorigenesis, with a small reduction at the promotional stage, suggesting the anticarcinogenic activities of ginseng (58). Ginsenosides Rg3 and Rg5 were found to show statistically significant reduction of lung tumor incidence in a newly established 9-week, medium-term anticarcinoge-nicity test model of lung tumors in mice, and ginsenoside Rh2 showed a tendency to decrease...

Nature Of This Cancer Type

The American Cancer Society (Jemal et al. 2006) has estimated that about 9,510 new cases of and 3,740 deaths from cancer of the larynx (ICD-9 161 ICD-O C32.0-C32.9) will occur in 2006. Laryngeal cancer ranks 16th in incidence and mortality among men in the United States, and 28th and 25th in incidence and mortality, respectively, among women. Both incidence and mortality are more than 4 times higher in men than women and are higher among blacks than whites, especially in men. The risk of developing laryngeal cancer increases with age. However, the incidence of laryngeal cancer, adjusted for age, has decreased by an average of 2.6 per year since 1988. Most cancers of the larynx are squamous-cell carcinomas that arise from the thin, flat cells (squamous cells) that line the upper airway. Those tumors, like squamous-cell carcinomas of the oral cavity and pharynx, develop gradually as normal cells develop into clones of progressively abnormal cells. As the clones accumulate genetic...

Early Ovarian Carcinoma Definition of Early Ovarian Cancer

Some of the earlier trials identified subgroups of stage I whose prognosis was excellent and therefore warranted a classification of low-risk for cancer recurrence and death. Subsequent studies often stratified the early-stage ovarian cancer populations into low-risk and high-risk groups (Box 8-2). In 1994, the National Institutes of Health (NIH) convened a Consensus Development Conference on ovarian cancer for the purpose of identifying issues that had sufficiently confirmed data at that time.1 Box 8-3 summarizes the conference's statement on management of stage I cancer. The conference panel could not reach consensus on the need for adjuvant therapy in the subsets of stage I not listed in the box, and they concluded that the most effective adjuvant therapy had not been established. The panel also recommended that patients with high-risk stage I cancers should be enrolled in clinical trials to identify adjuvant therapy that will improve survival.

Invitro and Invivo Anticancer Effects

Both propolis and CAPE inhibit cancer cell proliferation in vitro. In one study, crude extracts of propolis were cytotoxic to transformed mouse fibroblast cells. Proliferation was completely inhibited at about 220 jM, while CAPE alone was roughly six times more potent (90 percent inhibition at 35 jM).21, a In another study, the IC50 of a propolis extract against human nasopharyngeal and cervical cancer cells was about 13 to 33 mM.2 CAPE alone inhibited a large number of rodent and human cell lines the IC50 for most was 1 to 35 mM.3-5'21-24 The effects of CAPE seem to be specific to cancer cells. For example, it was selectively toxic to transformed fibroblast and melanocyte cells as compared to normal cells.21 CAPE may also have some cancer preventive effects. An oral dose of about 180 mg kg inhibited tumor formation in mice genetically prone to cancer.25 The equivalent human dose is about 1.7 grams. In addition, out of 25 natural compounds tested for cancer preventive activity, CAPE...

Evidence for Possible Anticancer Protection by Lycopene

Most of the indications with respect to cancer comes from human studies linking tomato intake, total estimated lycopene intake, and serum or plasma lycopene concentrations to the subsequent development of cancers (Table 5). There is a small amount of evidence from experimental animal studies, for instance, rat and mouse dimethylbenzanthracene-induced mammary tumor studies have supported Partly for historical reasons, there has been a particular interest in prostate cancer (Table 5). A large and early trial in the US (US Health Professionals Follow-up Study) reported an impressive difference between groups with high and low intakes of tomatoes and hence of lycopene for subsequent prostate cancer development, which was not shared with other carotenoids. Plausibility was enhanced by the fact that although human prostate lycopene concentrations are not especially high on an absolute basis (Table 3), they are higher than those of other carotenoids in this tissue. Subsequent studies have...

Gastrointestinal Tract Including Carcinogenesis

Chronic alcohol consumption is associated with an increased risk of cancer in the upper alimentary tract and the colorectum 109 , It might be possible that the production ofROS is involved in alcohol-associated carcinogenesis since chronic alcohol consumption leads to an induction of cytochrome P450 in the oral mucosa in the esophagus and in the colon of rodents 110,111 , Such an induction can also be demonstrated in the human oral mucosa 112 . In addition, the presence of xanthine oxidase has been located in the epithelial cells of the mouse and of the esophagus 113 . In an experiment by Eskelsson and co-workers, it has been shown that the number of esophageal tumors induced by nitrosamines and stimulated by chronic alcohol administration can be significantly reduced by the concomitant application of vitamin E 114 . Furthermore, this reduction is associated with a reduction in lipid peroxidation products in the esophagus. This is indirect evidence for the involvement ofROS in alcohol...

Second Primary Cancers

In breast cancer patients, smoking cessation is associated with a lower risk of lung primaries and pulmonary metastasis33 particularly for women treated with chest radiation.34-37 Continued smoking in Hodgkin's disease patients has also been shown to increase the risk of lung primaries.38 Multiple studies have demonstrated that head and neck cancer patients who quit smoking lower their risk of developing another new cancer, particularly in the lung, head and neck, gastrointestinal, and genitourinary regions.12-14,17,39-41 Finally, smoking cessation in lung cancer patients decreases the risk of developing another lung tumor or other tobacco-related cancer, particularly head and neck or bladder cancer.15,16,18,20,41

Prevalence Rates Of Smoking And Cessation In Cancer Survivors

Despite the growing awareness of the risks of continued smoking and the health benefits of cessation, the prevalence of smoking in cancer survivors is surprisingly high and similar to the U.S. adult population. Population-based estimates from the 1998-2001 National Health Interview Survey (NHIS) data show that 20 of cancer survivors are current smokers59 compared to 21 of adults in the general U.S. population.60 Further, smoking rates in cancer survivors show significant age-specific, cancer-specific, and time since treatment trends. Younger cancer survivors (18-40 years old) are more likely to report current smoking (42.6 ) compared to their age-matched cohort with no history of cancer (26.5 ).59 Also based on the 2000 NHIS data, Coups and Ostroff61 reported that 37.7 of 18- to 39-year-old cancer survivors were current smokers compared to 26.2. of non-cancer controls. Notably, time-stratified findings from Bellizzi et al5 showed that smoking rates are highest in the first year from...

Benefit 5 Protects against Breast Cancer

A recent study published by the Journal of the American Medical Association reported that even modest levels of physical activity, coupled with a reduced caloric intake to help lose body fat, decreased a woman's chances of having breast cancer. This was one of the largest studies of its kind involving 74,000 women between fifty and seventy-nine years old. An important point was that this exercise did not have to be intense While longer duration of physical activity provides the greatest protective benefit, such activity need not be strenuous. This is in keeping with what I have written about women benefiting most from low- to moderate-intensity exercise.

Efficacy of Smoking Cessation Interventions in Cancer

Consistent with the clinical practice guidelines, these cessation interventions generally have included standardized provider advice to quit, personalized education about the risks of smoking and the benefits of quitting, self-help print materials with content tailored to the needs and concerns of cancer patients, discussion and agreement on a quit date, and scheduled follow-up sessions. Interventions have been conducted in both outpatient and inpatient settings. The majority of studies have targeted lung and head and neck cancer patients. Very few randomized smoking cessation clinical trials with cancer patients have been published. These studies have utilized small sample sizes, focused primarily on hospitalized patients, and used nonrandomized designs. Both minimal and more intensive programs have been associated with dramatically high rates of cessation suggesting that the cancer survivor population is quite responsive to these cessation programs.63,79,80 In these studies,...

Changes in some of the demographic indicators and simultaneous increase in the incidence rate of breast cancer in

The data concerning the changes in some of the demographic indicators and simultaneous increase in the incidence rate of BC in Slovenia were collected and downloaded from open access electronic databases of the National Institute of Public Health of the Republic of Slovenia (National Institute of Public Health of the Republic of Slovenia, 2011), Statistical Office of the Republic of Slovenia (Statistical Office of the Republic of Slovenia, 2011), Slora-Slovenia and Cancer (Slora, 2011) of the Cancer Registry of Republic of Slovenia and from some of the similar sources (Cancer Registry of Republic of Slovenia, 2010 Curado et al (Eds.), 2009 Ilic et al., 2008). In this report the data in the figures refer only to the period from 1961 to 2006 since the data from periods earlier than 1961 are subject to limited availability. The data were processed and presented with the use of Excel 97 for Windows software package. As already mentioned above, BC is the most common type of cancer and most...

Clinical Care Approaches For Promoting Smoking Cessation In Cancer Survivorship

Our smoking cessation program at Memorial Sloan-Kettering Cancer Center follows a stepped-care model (see Figure 1), with all cancer care providers able to provide step 1, minimum intensity counseling to patients. Step 2 includes moderate intensity counseling through referral to the smoking cessation program, in which certified Tobacco Treatment Specialists (TTSs) (nurse specialists) perform an intake assessment of smoking behaviors, develop a tobacco treatment plan, offer brief counseling for cessation, advise options for smoking cessation pharmacother-apy, and conduct serial follow-up assessments with patients and survivors to monitor smoking cessation status and outcomes. Recognizing the geographic range of cancer survivors treated at a tertiary cancer care center, the TTSs also refer to local resources in the community. Step 3 is intensive treatment for smoking cessation delivered by psychologists who provide specialized care of smokers at high risk for continued smoking in...

The Commission On Cancer American College Of Surgeons Response To Hipaa

Abstract The Commission on Cancer is able to continue serving the CoC-Approved Cancer Programs following enactment of a business associate agreement between each of the programs and the ACoS. Worrisome unintended consequences, potentially threatening the value of the products that the CoC provides cancer patients, providers, and families, were not realized because of the Business Associate role that the CoC assumes with each of the CoC-Approved programs.

Reducing Cancer Risk

Prostate cancer A non-randomised non-blinded trial of 38 men with clinically significant prostate cancer found that 160 mg day red clover-derived dietary isoflavones, containing a mixture of genistein, daidzein, formononetin and biochanin A, significantly increased apoptosis compared with matched controls (P 0.0018). There were no significant differences between pre- and post-treatment serum levels of prostate-specific antigen, testosterone or biochemical factors or Gleason score in the treated patients (P 0.05). The study was performed in men undergoing radical prostatectomy however, it indicates that the isoflavones may halt the progression of prostate cancer by inducing apoptosis in low to moderate-grade tumours (Gleason grade 1-3) (Jarred etal 2002).

Background And Roles Of The Commission On Cancer

Established by the ACoS in 1922, the multi-disciplinary CoC sets standards for quality multidisciplinary cancer care delivered primarily in hospital settings, surveys hospitals to assess compliance with those standards, collects standardized and quality data from approved hospitals to measure treatment patterns and outcomes, uses the data to evaluate hospital provider performance, and develops effective educational interventions to improve cancer care outcomes at the national and local level.6 The CoC goals reflect the mission of the Commission, i.e., to provide the best cancer care for the patient through establishing standards for cancer programs, surveying and approving cancer programs, overseeing and coordinating national site-specific studies on patterns of care and outcomes of patient management through annual data collection and analysis and dissemination of data for 60 cancer sites, coordinating a network of 1,800 physicians, collaborating in community cancer control...

Goals of Second Line Chemotherapy in Ovarian Cancer

Unfortunately, available data fail to provide evidence for the legitimate curative potential of any existing second-line chemotherapeutic strategy in ovarian cancer.2,7-11 This is an important point and clearly distinguishes secondary from primary treatment, where it is rational to suggest that such treatment is being delivered to many patients with curative intent, even if only a limited percentage of individuals ultimately achieve this goal.1,2 In the absence of cure as an aim of treatment, what are the overall goals of second-line treatments in ovarian cancer There are a number of highly clinically relevant objectives of such therapy, as outlined in Box 9-3. A critically important aspect of anticancer management in this setting is to carefully balance the meaningful goals of therapy with the potential adverse effects of treatment, particularly when certain toxicities may be cumulative and persistent in their impact on an individual's quality of life (e.g., neuropathy).
