Adjuvant chemotherapy strategies

Older adjuvant cytotoxic regimes such as the triplet of doxorubicin, mitomycin and 5-fluorouracil (AMF) for six cycles to treat pancreatic and papillary cancers showed no overall survival advantage beyond two years, although there was a 1 and 2 year relapse-free survival advantage favouring chemotherapy over surgery alone. 7

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...

Combination chemotherapy and epidermal growth factor receptor EGFR inhibition

The role of erlotinib incorporated into the management of patients with locally advanced disease is being evaluated in the Groupe Cooperateur Multidisciplinaire en Oncologie (GERCOR) LAP07 phase III trial. 20 Patients are randomised initially to either induction gemcitabine or gemcitabine erlotinib. In those patients who do not progress after four months, there is a secondary randomisation into a chemotherapy (with either gemcitabine or gemcitabine erlotinib), or a chemoradiotherapy arm (with concurrent capecitabine) until tumour progression.

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...

Comparisons Of Longterm Effects Of Diagnosis And Treatment By Cancer Site Breast Cancer And Hodgkins Disease

Was expected that type and frequency of the physical dimension of QOL would be explained by type of treatment, age at the time of treatment and time since diagnosis. It was also expected that social and psychological dimensions of QOL would be explained by differences in educational attainment. The sample was composed of 141 individuals (55 male) who participated in two different surveys conducted at Stanford University Medical Center. The initial interviews were conducted in-person while the 12-year follow-up interviews were self-administered both surveys were conducted when the individual came to the clinic for a routine check-up. The second study was a 5-year follow-up of a population-based cohort of 185 women who were younger 50 years of age at diagnosis of breast cancer and were cancer-free 5 years later. The initial survey was in-person, often in the women's home, and the 5-year follow-up was a telephone survey.32 Comparative findings are organized according to Ferrell and...

Breastconserving Therapy After Preoperative Chemotherapy

Chemotherapy can also be administered in the preoperative setting (also known as neoadjuvant, primary or induction chemotherapy). There are several theoretical arguments for the use of preoperative chemotherapy. These include the ability to carry out in vivo assessment of tumor response, using the primary tumor to monitor and optimize treatment effects on micrometastases. Also, there is a theoretical advantage of decreasing drug resistance by early exposure to systemic therapy with the hope of improving disease-free and overall survival, as well as producing less favorable growth kinetics for micrometastases. Patients with a good response to neoadjuvant chemotherapy can become eligible for BCT even when their initial tumor was too large for this treatment. In the NSABP-B27 study, 87 of patients had a clinical response and 26.1 had a pathological complete remission after a combination of AC and docetaxel neoadjuvant chemother-apy.121 In the meta-analysis of neoadjuvant versus...

Combination chemotherapy

Although the benefit of chemotherapy in patients with advanced pancreatic cancer is well established, the magnitude of the effect is rather small, with an absolute improvement of survival at 5 years of 3 to 6 (survival rates from 1975-77 to 1999-2005) (Oberstein & Saif, 2011). Over the past decade, multiple randomized trials have been performed to assess a number of gemcitabine-combination chemotherapy regimens in an effort to improve these modest results. These have included combinations with 5-FU (Berlin et al, 2002 Riess et al, 2005), capecitabine (Herrmann et al, 2007 Bernhard et al, 2008 Cunningham et al, 2009), cisplatin (Heinemann et al, 2006 Colucci et al, 2002, 2009), oxaliplatin (Louvet et al, 2005 Poplin et al, 2009), irinotecan (Rocha et al, 2004 Stathopoulos et al, 2006), exatecan (Abou Alfa et al, 2006) and pemetrexed (Oettle et al, 2005a). Individually, although many of these studies observed some improvement in terms of response rate and progression free survival...

Reducing Chemotherapy Sideeffects

Results from a small, open, prospective study of subjects with advanced gastric cancer suggests that intravenous administration of a polysaccharide fraction isolated from E. purpurea may be effective in reducing chemotherapy-induced leucopenia (Melchart et al 2002). Test subjects had advanced gastric cancer and were undergoing palliative chemotherapy with etoposide, leucovorin and 5-fluorouracil. The median number of leukocytes 14-16 days after chemotherapy was 3630 microL (range 1470-5770) in the patients receiving herbal treatment compared with 2370 microL (870-3950) in the patients of the historical control group (P 0.01 5).

Breast Cancer Survivors

In related investigations, researchers studied utility values for 692 survivors of breast, colon, melanoma or lung cancer who participated in the 1998 National Health Information Survey. Utility scores were generally lower in the acute period within 1 year of diagnosis, and were highest in the period greater than 5 years from diagnosis. Pain was a significant negative predictor of utility in long-term survivors of breast cancer (P -0.06 95 CI -0.11, -0.012), colon cancer (P -0.13 95 CI -0.23, -0.03), and lung cancer (P -0.21 95 CI -0.37, -0.05). The other negative predictors were comorbid medical conditions.13

Dietary Fiber and Protection Against Breast Cancer

A growing number of studies have reported on the relationship of Dietary Fiber intake and breast cancer incidence, and the strongest case can be made for cereal consumption rather than consumption of Dietary Fiber per se (for an excellent review see Gerber 1998 ). Between-country studies, such as England versus Wales (Ingram, 1981), southern Italy versus northern Italy versus the United States (Taioli et al., 1991), and China versus the United States (Yu et al., 1991), and one study within Spain (Morales and Llopis, 1992), all showed an inverse correlation between bread and cereal consumption and breast cancer risk. The findings of Caygill and coworkers (1998) showed an inverse correlation between breast cancer incidence and both the current diet (p < 0.001) and the diet 20 years previously (p < 0.001). However, starchy root, vegetable, and fruit intakes were not related to breast cancer risk for either diet.

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...

Relative Integration of Thoracic RT with Chemotherapy for LSSCLC

While Warde's and Pignon's meta-analyses established the role of thoracic RT in the management of LS-SCLC, the question of what the optimal timing and integration of thoracic RT with chemotherapy remained unanswered. Murray et al. reported results from a trial on behalf of the National Cancer Institute of Canada (NCIC) which randomized 308 LS-SCLC patients receiving three cycles of CAV (cyclophosphamide, doxorubicin, vincristine) alternating with EP (cisplatinum and etoposide) to 40 Gy 15 fractions of thoracic RT given with either the first or final (third) chemotherapy cycle. Patients without progressive disease after completion of all chemoradiotherapy treatments were given prophylactic cranial irradiation (25 Gy 10 fractions). With a median follow-up time of almost five years, significantly improved progression-free survival (median 15.4 months versus 11.8 months, p 0.036) and overall survival (median 21.2 months versus 16.0 months, p 0.008) was observed in patients given early RT...

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...

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,...

Emerging Chemotherapy Response Predictors

The clinical importance of predicting who will and who will not respond to chemotherapy is intuitively obvious. If a test could predict who will respond to a given drug, the treatment could be administered only to patients who benefit, and others could avoid the unnecessary treatment and its toxicity. However, the practical development of chemotherapy response prediction tests poses several challenges. There are theoretical limits to the accuracy of any response predictor which measures the characteristics of the cancer only. Host characteristics which are not easily measured in cancer tissue, including the rate of drug metabolism, can have an important impact on response to therapy. Also, there is considerable uncertainty as to what level of predictive accuracy would be clinically useful. In fact, different levels of predictive accuracy may be required for different clinical situations. For instance, the clinical utility of a chemotherapy response prediction test that has 60 positive...

Does Adjuvant Chemotherapy Improve Outcome

Because of a relatively low rate of cancer recurrence in early ovarian cancer, the challenge of clinical trials has been to accrue enough patients to have the power to detect a clinically meaningful impact of adjuvant chemotherapy on either cancer recurrence or survival. The most notable studies indicating significant effects of adjuvant chemotherapy compared with observation are listed in Table 8-3. In 1980, the GOG reported that an 18-month course of melphalan significantly reduced the recurrence rate compared with either observation or pelvic radiation therapy.5 This result is surprising owing to the fact that the trial design was three arms and included only 86 patients with a large proportion of stage Ia grade 1 cancers, a group of patients who benefit the least from adjuvant chemotherapy. All four trials found that adjuvant chemotherapy significantly reduced the risk of cancer recurrence by an absolute value of 8 to 18 . Only one study, however, also demonstrated a significant...

Fatty Foods Breast Cancer

Women who eat more animal fat have a higher risk of premenopausal breast cancer. (In earlier studies, the same researchers found no link to postmenopausal women.) For roughly eight years, researchers tracked the diets of more than 90,000 premenopausal women, 7,800 of whom were diagnosed with breast cancer (average age 43) during that time. The risk of breast cancer was linked to red meat, whole milk, cream, ice cream, butter, cream cheese, and other cheeses (except cottage and ricotta).38

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.

Intraperitoneal Chemotherapy

The concept of treating optimally debulked patients with intraperitoneal chemotherapy has appealed to clinicians for over two decades. In early 2006, a GOG study concluded that intraperitoneal treatment appeared superior in this subset of patients.66 This trial randomized 429 patients to either standard intravenous cisplatin plus paclitaxel or intraperitoneal intravenous cisplatin plus paclitaxel (Fig. 8-11). The patients receiving intraperitoneal chemotherapy had a significant improvement in overall survival (median survival 65.6 versus 49.7 months). Toxicity, particularly neurotoxicity, was greater and quality-of-life scores were initially lower in patients treated with intraperitoneal chemotherapy. An earlier GOG randomized trial also provided strong evidence for the utility of intraperitoneal chemotherapy in optimally debulked patients.67 The NCCN has listed intraperitoneal therapy as an alternative manage

Chemotherapy for locally advanced and metastatic disease

The primary goals of treatment for advanced pancreatic cancer are palliation and improved survival. Although some effect on survival may be achieved, these benefits are usually limited to patients with adequate performance status (ECIG 0-2). Patients who present with very poor performance status may benefit from the administration of Gemcitabine, but comfort-directed measures are always paramount. Before initiating cytotoxic therapy, an open dialogue regarding the goals of treatment should take place, and adjunctive strategies should be discussed (including nonsurgical bypass, celiac block for pain of note debilitated patients with advanced disease may have abrupt changes in clinical status. Therefore, if treatment is begun, it should proceed with close follow-up. Patients may experience sudden onset of bleeding or thromboembolism, rapidly escalating pain, biliary stent occlusion, cholangitis, or other infections. Moreover, clinically meaningful tumor progression may develop quickly,...

Chemotherapy of Recurrent Potentially Platinum Sensitive Ovarian Cancer

As previously noted, there is very strong evidence to support delivery of a platinum-based chemotherapy regimen in the second-line setting in women who have previously experienced an objective response to therapy with this class of drugs.7-11 Unfortunately, there has been a rather profound absence of evidence-based studies that have directly compared a platinum-based regimen with a non-platinum program in the setting of recurrent ovarian cancer. However, the limited randomized experience does suggest superiority of a platinum-containing program in this clinical setting14 (Table 9-2 Fig. 9-2).Despite this fact, there are a number of reasons why an individual physician and patient may decide to avoid platinum in the second-line setting, despite a prior response to the drug (Box 9-4). The risk for the development of a platinum-associated hypersensitivity reaction is increasingly recognized as an important concern in this patient population. Up to 15 to 20 of women receiving a second-line...

Breast Cancer Metastasis

Abstract Distant metastases from breast cancer are common, especially in patients with positive axillary nodes. They often develop late and are the predominant cause of mortality from the disease. The natural history of breast cancer remains controversial. It is unclear whether metastasis has already occurred by the time of presentation, especially in the case of small, screen-detected tumours. The commonest sites of distant metastasis are bone, liver and lungs. Bony metastases are commonest in the axial skeleton, but also frequently occur in the long bones. Their complications include spinal cord compression, pathological fracture and hypercalcaemia. When there is clinical suspicion of distant metastasis, investigation consists predominantly of imaging techniques, such as bone scans, plain films, computed tomography and magnetic resonance imaging. After surgery to the primary tumour, adjuvant chemotherapy and hormonal therapy is used to treat occult micrometastatic deposits....

P53 And Breast Cancer

P53 mutation is uncommon in breast cancer families accounting for approximately only 1 of breast cancer predisposition.46 p53 protein overexpression or mutation is rare in normal breast or in benign breast conditions, although p53 protein accumulation has been linked to an increased risk of breast cancer in women with benign breast disease.47 Abnormalities in p53 function appear to be more common than specific p53 gene mutations in breast cancer, unlike many other cancer types. Loss of p53 normal function as the result of LOH (loss of one allele) is more common than the homozygous deletion (loss of both alleles), and is seen in up to 61 of the primary breast cancers45 and may precede the invasive phenotype (particularly in high-grade or comedo-type ductal carcinoma in situ (DCIS) .48 The observation of p53 mutation or over expression of p53 protein in up to 52 of primary breast cancer specimens, along with increasing knowledge of the characteristics of p53, has focused the attention...

The Chemotherapy Of Cancer

9.6.5 Chemotherapy 340 9.6.5.1 Achievements of chemotherapy 340 9.6.5.8 Combination chemotherapy 343 9.6.5.9 Adjuvant chemotherapy 344 9.12.1 Breast cancer At the point of clinical recognition of cancer, curative surgical or radiological treatment is only possible if metastasis of the primary tumour has not occurred. Therefore, early diagnosis is essential. Since about 50 of malignant tumours have metastasised prior to diagnosis, the condition is often beyond the reach of curative surgery or radiotherapy alone. It is in these cases that systemic chemotherapy can often help to reduce the total tumour mass. A number of genes have now been identified that, if inherited, can predispose individuals to certain types of cancer. For example, two genes, BRCA1 and BRCA2, have recently been identified and sequenced by UK and US researchers. These genes are inherited and are associated with breast cancer. Other genes associated with colon and bowel tumours are known to be inherited. This has lead...

Use of Natural Compounds to Reduce Adverse Effects of Chemotherapy

Many chemotherapy drugs induce necrosis or apop-tosis in cancer cells by generating free radicals, but at the same time, these prooxidant mechanisms are responsible for adverse effects on normal cells. For example, doxorubicin, one of the most widely used chemotherapy drugs, induces DNA damage in cancer cells through a prooxidant mechanism. One of its primary side effects is heart damage that is also caused by its prooxidant ac-tion.9'10'11 Because doxorubicin treatment can reduce total antioxidant stores in the body, antioxidant treatment might maintain these stores and protect normal tissues from adverse effects.12'13 This has in fact been reported in a large number of animal studies that tested doxorubicin in combination with antioxidants such as melatonin, vitamin E, vitamin C, combinations of vitamins C and E, beta-carotene, curcumin, catechin, the antioxidant drugs dexrazoxane and probucol, and oth-ers.14-23 If antioxidants can help prevent adverse effects of prooxidant...

Variables Related to Adjuvant Chemotherapy and Response

Eisenkop and colleagues14 examined the effect of the use of salvage chemotherapy before attempting surgical cytoreduction. Patients who had not received salvage chemotherapy experienced improved survival after surgery for recurrence. The investigators also evaluated the effect of previous response to chemotherapy in the course of disease. They found that the patient's response or lack of response to platinum-based regimens had no effect on postoperative survival. Because surgery alone is rarely curative, surgical cytoreduction is generally not attempted without a plan for administering postoperative chemotherapy. In the DESKTOP trial21 women who went on to receive platinum-based chemotherapy regimens after secondary cytoreduction experienced improved survival compared with patients who received other chemotherapy regimens (odds ratio 1.84 95 confidence interval 1.13-3.01). Most patients chosen for secondary cytoreduction have by definition platinum-sensitive disease and are candidates...

Strategies For Manipulation Of The P53 Pathway In The Treatment Of Breast Cancer

The insights provided by p53 laboratory research over three decades are now moving to clinical applications for enhanced diagnostic, prognostic, and therapeutic intervention. The detailed strategies for engaging and manipulating the p53 pathway have been comprehensively reviewed in the literature for a wide range of human cancers.5,10,86 For breast cancer, where not only p53 mutation but also aberrations of the p53 pathway occur commonly, many of these strategies hold promise.

Hyperthermic Intraperitoneal Chemotherapy

An interesting treatment modality being investigated in the setting of recurrent ovarian carcinoma limited to the peritoneal cavity is hyperthermic intraperitoneal chemotherapy (IPHC or HIPEC).45,46 Hyperthermia has been shown to increase the response to cytotoxic agents in human cell lines and animal models.47,48 Small series in optimally cytoreduced recurrent ovarian carcinoma have shown some promise.44,45 However, the infusion must be done over 90 minutes, and therefore the procedure increases operating room times. A mean operating room time of nearly 10 hours was reported by Helm and colleagues.45 The preliminary reported median survivals do not appear to be strikingly better than those seen in Table 10-1. Although this is an Further chemotherapy options

Incidence of breast cancer in Pakistan

In Pakistan, breast cancer has maximum prevalence of all types of cancer, with frequencies similar to Western population. It affects mostly young women (45 or above) in Pakistan with a high frequency as compared to Caucasian women (Kakarala et al., 2010), often presenting in advanced stage (Malik, 2002). The low socio-economic status and reproductive issues such as low parity and late first pregnancy may be responsible for higher incidence of breast cancer in Pakistan. It is described that patients with lower socio-economic status (SES) had larger, more aggressive tumors with worsened survival outcomes (Aziz et al., 2010). The mutations of BRCA1 and BRCA2 genes are also considered as responsible factors for the greater numbers of breast cancer in Pakistan. As Pakistan has the maximum number of consanguineous marriages in the world (Hashmi, 1997), the transfer of these mutations after such marriages is supposed to be a vital factor in raising breast cancer cases in Pakistan (Shami et...

Biological explanation of breast cancer

Breast cancer usually arises after menopause (age 40+), but it can also arise before menopause in very rare cases. The ovarian-pituitary axis synchronizes the normal breast physiology during the reproductive cycle. The biological reason for it is that the glandular component of the breast gradually degenerates after menopause and the breast is mostly substituted by adipose tissue. Any problem in this process causes the development of breast cancer, whereas by epithelial cells of the breast ducts, uncontrolled growth and survival takes place, and in later stages the characteristics of neo-angiogenesis, invasion and metastasis occurs (Heldermon and Ellis, 2006).

Values for children on chemotherapy

Oncologists consider all of the blood values to get the total picture of the childs reaction to illness, chemotherapy, radiation, or infection. Trends are more important than any single value. For instance, if the values were 5.0, 4.7, 4.9, then the second result (4.7) was insignificant. If, on the other hand, the values were 5.0, 4.7, and 4.6, then the trend would indicate a decrease in the cell line.

Initial Chemotherapy Choice

Chemotherapy is basic treatment of SCLC, always used, even for the rare surgically treated patients, according to a neoadjuvant or an adjuvant mode. For all other inoperable patients, it is an emergency to begin it as soon as possible, the day of histologic diagnosis. It cannot be the same for all patients like yet often recommended for cisplatin-etoposide as a standard 1 . This statement has never been demonstrated Patients with good clinical prognosis factors must receive a four-drug protocol treatment. A phase III randomised trial had already proved survival benefit of epidoxorubicin plus cyclophosphamide addition to cisplatin-etoposide compared to cisplatin-etoposide alone in selected extensive SCLC 2 . This result is not contradictory with our results obtaining no survival difference between cyclophosphamide-doxorubicin-etoposide (CDE) and the same plus cisplatin (PCDE) for 457 patients with poor prognosis data 3 , because the choice of drugs has to be adapted to the patient...

Neoadjuvant chemotherapy

Neoadjuvant chemotherapy (NAC) has been a common approach for the management and treatment of locally advanced breast cancer (LABC). It is applied very effectively for treatment of patients with LABC before breast and axillary lymph node resection (Pusztai, 2008). The NAC is aimed to reduce tumor size subsequently aiding mastectomy and radiotherapy (Cleator et al., 2002 and Pusztai, 2008). NAC is better treatment option because it averts adverse physiological reactions (Alvarado-Cabrero et al., 2009).

Chemotherapy Adaptations

Response evaluation has to be done quickly. Often the first standard X-ray is sufficient to demonstrate objective response or to change treatment if no response. For rapid complete responders, chemotherapy may be limited to six courses 10 .For partial responders, chemotherapy has to be going on as long as progression disease appears because stop treatment is dangerous in a so progressive cancer. A second-line chemotherapy, even a third-line chemotherapy 11 , can be used for non-responders or relapsing patients. A long time elapsed after complete response and discontinuation of treatment lead to use again the initial protocol 12 . For other patients, monotherapy with topotecan gives interesting results but with a high medullar toxicity 13 , so found in our personal experience. In this situation, we have preliminary tested with some success an oral and low-cost association of lomustine-etoposide-cyclophosphamide 14 which is now in evaluation comparing it with a conventional intravenous...

HR breast cancer and targeted therapy

Estrogen is a well-characterized growth factor in about 60-70 of breast cancer patients (Clemons and Goss, 2001). The malignant epithelial cells depend on reproductive hormones, specifically estrogen in ER+ tumors (Heldermon and Ellis, 2006). The initial endocrine therapy of breast cancer was removal of the ovaries (oophorectomy) (Taylor et al., 1998). Many thriving remedies have been formulated to decrease or eradicate circulating estrogen or to obstruct its communication with genomic target objects. The specific ER antagonist tamoxifen is recommended as adjuvant endocrine therapy for the hormone receptor positive early breast cancer (Sehdev et al., 2009). Endocrine therapies for ER+ patients include three types of agents that (i) directly target ER through molecules that bind ER and change ER function (ii) estrogen deprivation through aromatase inhibition or ovarian suppression and (iii) sex steroid therapies, including estrogen, progestins and androgens.

Primary And Metastatic Breast Cancer

Currently, treatment of metastatic breast cancer patients with HER2-positive tumors is based on HER2 status derived from the primary tumor, which was generally removed many years previously and stored as paraffin-embedded blocks. In a report by Zidan et al,59 it was pointed out that HER2 status of the primary tumor may not accurately reflect the HER2 status of the metastatic tumour, and that this should be taken into account when making treatment decisions. Those investigators demonstrated 14 discordance between primary and metastatic tumors by IHC. Edgerton et al,60 employing IHC and FISH, reported 20 discordance between the primary and metastatic tumor, which was due to normal HER2 expression in the primary tumor and HER2 overexpression in the metastatic tumor. Gancberg et al61 compared HER2 status of the primary breast tumor with that of at least one distant metastatic tumor in 107 patients using both IHC and FISH. There was a 6 (6 100) rate of discordance with IHC between the...

Triplenegative breast cancer treatment

CCN1, also known as Cyr61 (cysteine-rich 61), is a proangiogenic factor, increased CCN1 expression is associated with the development of tumors (O'Kelly et al., 2008), e.g., in about 30 of invasive breast carcinomas, and particularly in triple-negative breast carcinomas (TNBC). TNBCs patients had been treated with bisphosphonate in combination to chemotherapy. Zoledronic acid (ZOL) is a bisphosphonate having direct antitumor activity in breast tumor cells by preventing independent growth, branching and morphogenesis by targeting CCN1 overexpressing cells through a negative regulation of CCN1 by FOXO3a it is a new therapeutic approach for TNBC (Espinoza et al., 2011).

Bone Marrow Stimulation During Chemotherapy

Haemopoiesis was studied in 88 patients with lung cancer during combination treatment with chemotherapy and a 5. balcalensls extract. Administration of the plant preparation was associated with haemopoiesis stimulation, intensification of bone marrow erythrocytopoiesis and granulocytopoiesis, and increased numbers of circulating precursors of erythroid and granulomonocytic colony-forming units (Goldberg et al 1997).

Chemotherapy drug list

Drugs used for chemotherapy are known by various names. You may hear the same drug referred to by its generic name, abbreviation, or one of several brand names, depending on which doctor, nurse, or pharmacist you are talking to. The list below gives the most common names used for chemotherapy drugs and tells you what name is used in this chapter so you can easily find it on the following pages of detailed information. My daughter had serious problems with rashes during maintenance. The doctors thought she had developed an allergy to the weekly methotrexate. She often would be covered with rashes that looked like small, red circles with tan, flaky skin inside. They were extremely itchy and unattractive. We spent hundreds of dollars at the dermatologist trying various prescription remedies. None worked. In desperation, I went to our local herbalist and asked if she had anything totally nontoxic, which would help the rash but not affect her chemotherapy. She sold me a small tub of salve...

Choice of Chemotherapy and Duration of Treatment

Generally, choice of adjuvant chemotherapeutic agents for early-stage disease has been extrapolated from management of advanced-stage ovarian cancer. See the section on Advanced Ovarian Carcinoma, later in this chapter. Many of the investi-gational trials in early-stage ovarian cancer compared cisplatin-based combination chemotherapy to radiation therapy 18-20 (Table 8-5). Meta-analyses of these types of trials have shown no significant difference between chemotherapy and radiation therapy for disease-free and overall survival.21 Carboplatin replaced cisplatin as the standard platinum in treating ovarian cancer after several studies concluded that carboplatin and cisplatin had equivalent efficacy in treating advanced disease.22 ICON-2 demonstrated that single-agent carboplatin effected the same median survival and 2-year survival (33 months and 60 ) as the combination of cyclophosphamide-doxorubicin-cisplatin in advanced disease.23 As in advanced disease, platinum-based chemotherapy...

Endocrine Therapies For Breast Cancer

Breast cancer is the most common female cancer in the Western world (accounting for 28 of all cancers) and the leading cause of death by cancer in women (approximately 20 ). Although the mortality rate has stabilized or decreased, the incidence of breast cancer is still rising in all European countries.1 Around two-thirds of breast cancers are hormone (estrogen)-dependent as they are positive for estrogen receptor alpha (ERa) and or progesterone receptor (PR). As estrogen is the principal molecule stimulating the proliferation of these ERpositive tumors, blocking estrogen signaling has been the main endocrine therapy for patients with ER-positive breast cancer. Over the past three decades, the antiestro-gen tamoxifen, which belongs to the first generation of selective ER modulators (SERMs) and which acts as an estrogen antagonist on the breast, has been the gold standard for the endocrine treatment of all stages of these cancers. Tamoxifen acts as a SERM by blocking the AF-2 domain of...

Chemotherapy

Documentation of the association between chemotherapy and fatigue has been under way since the early 1980s and gathered momentum in the 1990s. Investigations have been conducted with patients with breast cancer, lymphoma, lung cancer, ovarian cancer, and other solid tumour types, although by far the greatest number of data have been collected with those in the first group, namely breast cancer. It is now acknowledged as the most frequent and distressing side-effect of chemotherapy. Compelling descriptions of the impact of fatigue on patients' quality of life and ability to perform self-care are available (Fernsler 1986 Rhodes et al. 1988 Nail et al. 1991 Ferrell et al. 1996 Pearce and Richardson 1996 Hilfinger Messias 1997 Ream and Richardson 1997 Richardson and Ream 1997). Evidence suggesting an association between the administration of chemotherapy and feelings of fatigue has been collected during studies conducted to document the range of side-effects associated with this treatment...

Breast Cancer

The data examining sugars intake and breast cancer have been inconsistent (World Cancer Research Fund American Institute for Cancer Research, 1997) and therefore are insufficient to determine a role of sugars in breast cancer (Burley, 1998). There are indications that insulin resistance and insulin-like growth factors may play a role in the development of breast cancer (Bruning et al., 1992 Kazer, 1995).

Role of chemotherapy

Since the 1980's SCLC has been well-known to be an exquisitely chemosensitive tumor. The current standard chemotherapy regimen for LS-SCLC is a combination of cisplatin-etoposide. Though concurrent chemoradiotherapy is the current standard of care for patients with LS-SCLC, no accepted consensus regarding what the most appropriate chemotherapy regimen for this patient group exists. Three separate published meta-analyses or systematic reviews have attempted to clarify this issue. Pujol's meta-analysis studied 19 randomized trials including over 4000 patients enrolled in studies published from 1966-1999 to examine the role of cisplatin in treatment of SCLC. Trials compared cisplatin-containing regimens to regimens without cisplatin. The authors reported that patients treated with cisplatin-containing regimens had a lower risk of death at 1 year which translated to a significantly increased 1-year survival probability by 4.4 6 . Mascaux's meta-analysis of 36 randomized trials included...

Use Of Prognostic And Predictive Factors In Clinical Practice

The standard prognostic factors such as tumor size and node status provide important information about likely patient outcome, but within the good prognosis groups such as axillary node-negative cases there can be differences in behavior. There is increasing emphasis on separating defined prognostic groups into low and high risk,14 and using this, along with predictive markers, for the selection of adjuvant systemic therapy. Expert consensus meetings such as those held at St Gallen consider the primary therapy of early breast cancer and make recommendations which are published every 2 years or so.15-17 The Early Breast Cancer Trialists' Collaborative Group undertake quinquennial overviews of the randomized trials in breast cancer, with the last overview being published in 2005,18 and these provide data on recurrence and mortality rates in relation to therapy. Using this, and in conjunction with the Nottingham Prognostic Index (NPI),8 a prognostic table has been devised19,20 and...

Micrometastatic And Metastatic Disease

The methods available for detection of disseminated and circulating tumor cells, and their clinical significance, are the focus of Chapter 7. Chapter 8 reviews progress in the investigation of the clinical utility of plasma DNA and RNA analysis for determining breast cancer behavior. It also describes how data from studies of tumor-specific alterations in circulating cell-free DNA indicate that analysis of nucleic acids in blood could become a diagnostic test.

Gene Expression Profiling

In the first edition, gene expression profiling was referred to in the Introduction, but now merits a chapter. The initial publications were concerned with subcategorization of breast cancers,27-29 but soon the emphasis was on identifying expression profiles relating to prognosis and the prediction of response to endocrine therapy and chemotherapy, and these are discussed in Chapter 11. Genomic prognostic tests are now available. As the authors of Chapter 11 point out, no prospective randomized studies have been completed to demonstrate improved patient outcome by the use of these new tests and the two studies currently underway will not report for several years. They do point out that some forms of clinical benefit from novel tests may be more subtle than improvements to survival.

Miscellaneous And Molecular Factors

Overexpression of EGFR correlates with estrogen receptor negativity and resistance to tamoxifen,6 and clinical trials are underway to assess its therapeutic potential. Although there are some promising data from results of trials of the dual HER2 and EGFR tyrosine kinase inhibitor, lapatinib, in HER2-positive breast cancer, to date some other EGFR inhibitors have proven somewhat disappointing. In particular, there are difficulties with methodology for selection of those patients most likely to respond to these new drugs.61 Other molecular markers have been widely described. For some, changes are common in invasive breast cancer p53 is mutated in nearly one-third of breast carcinomas and an association with an aggressive clinicopathological pheno-type has long been recognized (see Chapter12).6 Evaluation of proliferation markers MIB1 Ki67 antigen,62,63 proliferating cell nuclear antigen (PCNA) and S-phase fraction have shown a correlation with prognosis (see Chapter 3). Other molecular...

Assessment of proliferation

Prognostic value of proliferation in breast cancer The different methods for assessing proliferation have all been tested for their prognostic value in invasive breast cancer. Most studies have been performed on sporadic patients, and a few on BRCA1 2-related cases, which in general show higher proliferation compatible with their poorer prognosis.11 A high thymidine labeling index has been shown to be associated with poor prognosis in lymph node-positive and -negative breast cancer patients,12-28 although not in all studies.29 For BrdU, only a few clinical studies have been published. Thor et al30 compared BrdU with the mitotic index and the Ki67 index, and found comparable prognostic values for all three techniques. Goodson et al31 found BrdU The Ki67 labeling index on frozen sections was prognostically relevant in several studies of invasive breast cancer.42-44 The paraffin-reactive MIB1 antibody against Ki67 has confirmed the prognostic value of Ki67 on archival mater-...

The Influence Of Radiotherapy On Local Recurrence

As outlined above, radiotherapy given after surgery is very important to eradicate microscopic tumor left in the breast after lumpec-tomy, and thus to achieve acceptable LR rates. Randomized trials2-5,81,82 have demonstrated that adjuvant radiation therapy following conservative surgery reduces the risk of local recurrences remarkably compared to surgery alone.2-5,81,82 In the nonirradiated lumpectomy cohort in the National Surgical Adjuvant Breast Program (NSABP)-B06 trial, a local recurrence rate of 39 was found, compared to 14 in the irradiated patients at 20 years of follow-up.2 The local recurrence rates found in the other studies for the group of nonirradi-ated patients are similar to these results. A recent meta-analysis by the Early Breast Cancer Trialists' Collaborative Group, studied a group of 7300 patients that were treated with breast-conserving surgery in trials of radiotherapy. They showed a 5-year local recurrence risk of 7 versus 26 (absolute reduction 19 ), and...

And isolated tumor cells

This chapter will summarize several aspects of nodal micrometastases in breast cancer. It will briefly deal with the term itself, the methods used for the detection of these low-volume metastases, and some interpretation issues. Finally, it will discuss the prognostic and predictive implications of micrometastases whether they have a prognostic impact on survival, and whether they are predictive of nonsentinel node involvement when found within a sentinel lymph node. Obviously, predictive, in this sense is different from the general use of this term, but is nevertheless justified. others. To my knowledge, micrometastases were originally named so by Huvos et al,1 because they had been supposed to be detectable only by microscopy instead of being picked up at gross examination. A noninclusive size limit of 2 mm was suggested by these authors, who found no survival disadvantage for breast cancer patients with only micrometastases as compared to those with no metastasis at all, after a...

Immunocytochemical staining

Several different assays have been developed to detect DTC in breast cancer and other types of carcinomas. One major approach to identify DTC is immunocytochemical staining with monoclonal antibodies against epithelial or discrimination was introduced for DTC CTC analyses.37 This technique was designated epithelial immunospot (EPISPOT) and is based on the secretion or active release of specific marker proteins using an adaptation of the enzyme-linked immunospot (ELISPOT) technology (Figure 7.2). The EPISPOT assay offers the advantage that only viable tumor cells will be detected and that protein secretion can be detected at an individual cell level.38 For the detection of breast cancer-derived DTC CTC, MUC1 and CK19 were used as marker proteins.39 MUCl-secreting CTC were detected in all metastatic breast cancer patients analyzed, whereas such cells were not observed in healthy controls. Moreover, the enumeration of both MUC1- and CK19-secreting cells allowed the detection of viable...

Of Disseminated Tumor Cells

DTC in BM of breast cancer patients have been characterized with immunological double staining to identify biological features which might favor early dissemination. Multiple characterization approaches of DTC in BM show a considerable phenotypic heterogeneity in particular, the human epidermal growth factor receptor 2 (HER2) proto-oncogene appears to define a very aggressive subset of DTC with an increased invasive capability40,41 and has gained substantial importance as a biological target for systemic therapy in breast cancer.42 It can be demonstrated that the presence of HER2 expressing DTC is also associated with impaired prognosis.43 Furthermore, there is also some evidence of a prognostic effect of HER2-positive CTCs in stage I III breast cancer.44 In addition, most DTC and CTC do not express the proliferation antigen Ki67 and may therefore be resistant to chemotherapy.45,46 A detailed molecular description of DTC in BM of breast cancer patients without clinical signs of overt...

Biology Of Minimal Residual Disease

Only half of the breast cancer patients with DTC relapse, whereas the other half remain free of overt metastasis over a 10-year follow-up period (Table 7.1).56 This finding is in line with data from animal models and suggests that a significant fraction of DTC might never develop into overt metastases but might remain in a dormant state. However, the persistence of DTC in BM even years after primary treatment is linked to an increased risk of late metastatic relapses in breast cancer.57 Thus far, little is known about the conditions required for the escape from the dormant or quiescent phase into the dynamic phase of metastasis formation. The steady-state regulating dormancy might be disturbed by both changes in the DTC (e.g. additional mutations) and the surrounding microenvironment (e.g. decrease in immune surveillance or increased angiogenetic potential).58-60 Among the protein characteristics, expression of the tyrosine kinase receptor HER2 on DTC and CTC appears to be linked to...

Detection Of Disseminated Tumor Cells And Circulating Tumor Cells

Both early diagnosis of breast cancer and identification of metastases can improve the success of breast cancer treatment.4 Two approaches currently under close scrutiny for diagnostic and prognostic use are detection of disseminated tumor cells (DTCs) and detection of circulating tumor cells (CTCs), as discussed in Chapter 7. Although the risk of invasive bone marrow aspiration has made its routine use for breast cancer screening and follow-up problematic for patients, a number of groups have successfully detected DTCs in the bone marrow in primary breast cancer patients (reviewed by Slade and Coombes5). Detection of CTCs in the blood is obviously a much less invasive procedure. Their presence probably reflects a relapse or metastasis hence, detection of CTCs may be most useful in metastatic disease and for monitoring of the adjuvant situation.6 However, CTCs have been detected at a low frequency in early stage disease7 and recently CTCs were detected in 10 of 35 (29 ) stage I...

Detection Of Circulating Nucleic Acids In Plasma Or Serum

Subsequently, patients with cancer were shown to have higher levels of free circulating plasma DNA than those with nonmalignant disease, often > 100ng ml of plasma.11,16-18 Leon et al16 used a radioimmunoassay to study the level of free DNA in the serum of 173 patients with cancer and 55 healthy individuals. The mean DNA concentration was 13ng ml in the healthy controls and 180ng ml in the cancer patients.16 Similar levels were reported for 26 patients with breast cancer, where the mean concentration of DNA in plasma was 211 ng ml but was only 21 ng ml for 92 healthy female controls (p < 0.01) matched closely for age and menopausal status.19

Detection Of Tumorspecific Alterations In Cellfree Dna In Plasmaserum

Two key studies published back-to-back in 1996 first demonstrated that tumor-specific loss of heterozygosity (LOH) could be detected by PCR in the plasma and serum of patients with advanced small cell lung cancer, and head and neck cancer, respectively.30,31 Tumor specific LOH were subsequently detected in the plasma of breast cancer32,33 and colon cancer patients 34 and K-ras and p53 gene mutations,35-37 and aberrant promoter hypermethylation of tumor-suppressor genes including pl6INK4a were demonstrated in non-small cell lung cancer and liver cancer patients, respectively.38,39 TUMOR-SPECIFIC GENETIC ALTERATIONS IN SERUM PLASMA DNA OF BREAST CANCER PATIENTS Most studies of breast cancer plasma DNA have focused on detection of LOH and or p53 mutation. Silva et al33 first analyzed 62 breast cancer cases for LOH and or microsatellite instability (MSI) at 6 polymorphic markers, p53 mutations, and promoter methylation of p16INK4a. They identified 56 cases (90 ) with at least one...

Detection Of Epigenetic Change

DNA methylation at CpG dinucleotides in the promoter region of many genes is commonly associated with transcriptional gene silencing. Gene hypermethylation is therefore another mechanism for inactivation of tumor-suppressor genes,53 and has been shown to be a frequent and early alteration in many tumor types, including breast cancers.54-56 Hence, early methylation changes might prove to be useful markers for cancer screening if they are also tumor specific. A number of tumor-suppressor genes, including RAS-associated domain family protein 1A (RASSFla)57 and adenomatous polyposis coli (APC),58 have been shown to be hypermethylated in breast cancers but unmethy-lated in normal cells, and these and other targets are currently being studied as potential cancer-specific biomarkers in both serum and plasma. Thus far, there have been five studies published, which have examined promoter hyper-methylation in paired tumor and serum, or plasma DNA from breast cancer patients using PCR-based...

Conclusions And Possible Future Perspectives

DNA, several studies have shown alterations in plasma or tumor only (e.g. Silva et al37 and Shaw et al50). Garcia et al74 showed that heterogeneous tumor clones, and not PCR artefacts, could explain some nonmatched alterations between plasma and tumor DNA. Clearly, molecular markers which show homogeneous alterations in tumor are desired for analysis in plasma DNA. DNA methylation-based biomarkers, and detection of common mutations, are probably the most attractive for development, although each will require close scrutiny of assay sensitivity and specificity. DNA changes have the advantage of being qualitative (present or absent) rather than quantitative, such as for mRNA and pro-tein.50 However, given the differences in amounts of free DNA detected between cancers and controls, it might be useful to combine both qualitative and quantitative criteria for detection of tumor-specific DNA in blood. A number of research groups, including our own, are currently following up different...

Progesterone receptor

About 65-75 of primary breast cancers express ER over half of these also express PR, Retrospective studies of patients with metastatic disease, most receiving tamoxifen, supported this idea.58 PR-negative tumors consistently respond less well to endocrine therapy than PR-positive tumors, although some do benefit. Elevated PR levels significantly and independently correlate with a higher probability of response, longer time to treatment failure, and longer overall survival in patients with metastatic disease treated with tamoxifen.56,101 Data confirming the predictive value of PR also come from adjuvant and neoadju-vant trials showing that, in agreement with the studies in metastatic disease, patients with ER-positive PR-positive tumors benefited far more from tamoxifen than those with PR-negative tumors.54,102-105 Recent supporting data also showed that PR status provides predictive value for adjuvant endocrine therapy in older ER-positive breast cancer patients.106 In all these...

Progesterone receptor isoforms

Another field of future investigation is to decipher the functional importance of the altered expression of PR isoforms and how this may affect the response of breast tumors to endocrine therapy. PR is expressed as two iso-forms - PR-A and PR-B, which are products of a single gene but which are under the control of two distinct promoters.116 The two isoforms possess different, promoter- and cell line-specific transactivation properties. Studies have shown that in poor prognostic tumors, the ratio between PR-A and PR-B is altered, with PR-A predominating and loss of PR-B.117 An overabundance of PR-A may be associated with resistance to tamoxifen,117 while functional polymorphism resulting in increased production of PR-B may be associated with an increased risk of breast cancer.118 Other findings showed that PR-B expression was correlated with good prognostic markers and better overall survival in breast cancer.119 In a study of T47D human breast tumor xeno-grafts, tamoxifen...

Downregulation of estrogen receptors by mitogenactivated protein kinases

Although, as established above, growth factor pathways can enhance ER phosphorylation, transcriptional activity and cell growth in a lig-and-independent manner, paradoxically a decline in ER expression is also a possible outcome when growth factor signaling is extreme or sustained. Evidence for this arises from several stable transfection studies in ER-positive breast cancer cells. Such studies demonstrate that growth factor signaling elements comprising the EGFR HER2 pathway, which share an ability to hyperactivate ERK1 2 MAP kinase, all act to impair ER function and promote ER loss when overexpressed in ER-positive breast cancer cells. In our own laboratory, we have shown that constitutive upregulation of MEK1 in MCF-7 cells leads to a substantial increase in ERK1 2 MAP kinase activation, decreased ER level, and marked loss of expression of the ER-regulated gene progesterone receptor (PR) (RA McClelland, unpublished observations). Similarly, El-Ashry and colleagues39,40 have noted...

Nongenomic mechanisms

Shown to be tethered to the plasma membrane through either binding to the lipid raft proteins caveolin-1 and flotillin or complexing with a range of membrane-associated signal transduction proteins such as growth factor receptors and G proteins.51 In breast cancer cells, signaling via membrane ER, or membrane-initiated steroid signaling (MISS), has been shown to involve the coupling of ER with EGFR, HER2, IGF-1R and SRC, providing important mitogenic signals to epithelial cells through the subsequent recruitment and activation of downstream p38 and ERK1 2 MAP kinase pathways (Figure 10.2, 2b).5051 Interestingly, MISS has also been shown to subsequently impact on ER transcriptional activity through MAP kinase-mediated phosphoryla-tion of nuclear ER and its associated coactiva-tor AIB-1 in human epidermal growth factor receptor 2 (HER2)-overexpressing cells, providing an integrated genomic nongenomic signaling network which can mediate both acute and long-term actions of estrogen.51,52...

Extracellular signalregulated kinases 1 and 2 mitogenactivated protein

Exhibited objective responses (i.e. complete (CR) or partial (PR) responses) to tamoxifen as measured at 6 months after initiation of antihormonal therapy. Responses were of extended duration with a longer patient survival, as measured from the initiation of endocrine therapy. These low levels of pMAP kinase may be critical to the growth of such tumors since, using sequential tamoxifen-treated samples obtained from primary elderly breast cancer patients, we have been able to detect further decreases in pMAP kinase in parallel with the clinical tamoxifen response profile. Moreover, as stated above, we have demonstrated some cell growth inhibition of the endocrine responsive breast cancer line MCF-7 with the MEK1 inhibitor PD098059, despite only minimal activation of ERK1 2 MAP kinase. Such data again suggest that the diminished pMAP kinase levels detectable in endocrine responsive disease may be reflective of highly efficient regulation of enzyme phosphorylation. Some link has been...

Novel Molecular Tests In The Clinic

Breast cancer is a clinically heterogeneous disease and it is generally accepted that the different clinical course of patients with histo-logically similar tumors is due to molecular differences among cancers. Therefore, detailed molecular analysis of the cancer could yield information that may improve clinical outcome prediction. It is also increasingly recognized that molecules which determine the behavior of neoplastic cells act in concert and form complex regulatory networks. Any individual gene may only contain limited information about the activity of the entire network. It is reasonable to hypothesize that examining many genes simultaneously will Table 11.2 Examples of emerging molecular diagnostic tests to aid decision-making in breast cancer from chemotherapy from chemotherapy Recently, several novel multigene molecular diagnostic tests became commercially available, or are near to commercial introduction, in the USA and Europe (Table 11.2). The routine adoption of these...

When Is A New Diagnostic Test Ready For Routine Clinical

A test in the clinic, physicians must decide what value the test provides in medical decision-making. It is important to consider that even if a test is not indicated for every patient with breast cancer, it could provide clinical value for some. Many existing and well-accepted diagnostic tests fall into this category. For example, magnetic resonance imaging (MRI) is not performed on all patients with newly diagnosed breast cancer or with a suspicious lump in the breast however, it is a very useful test for a subset of woman with these conditions. Many of the emerging molecular prognostic and predictive tests also fall into this category. Sometimes decisions can be made about risk of recurrence relatively easily based on clinical characteristics of the disease and the currently available moderately accurate molecular predictors add little further value. Patient preference for aggressive therapy, even if the risk of recurrence is low and particularly if the risk of adverse events from...

P53 regulation through the Nterminal transactivation domain

Belonging to the transcription machinery include MDM-2, the DNA sequence of Ts and As where transcription factors bind (TATA) box-binding protein (TBP), TBP-associated factor (TAF), the p62 component of transcription factor IIH (TFIIH) and p300 CPB (CREB Binding Protein).15 Amongst the key p53 N-terminal-interacting proteins, in which altered expression is demonstrated in many cancers -including breast cancer - is the MDM-2 protein.22 MDM-2 controls the biological activity of p53 and targets p53 for destruction, acting as an E3 ligase to conjugate ubiquitin to p53, which provides a signal for p53 to be degraded by the proteasome. MDM-2 is a target gene of p53 and is therefore upregulated when p53 is activated, thus providing an inbuilt negativefeedback loop mechanism whereby p53 expression is controlled at the cellular level. The p53-MDM-2 protein interaction is of physiological relevance, as evidenced by overexpression of MDM-2 protein inactivating wild-type p53 in soft tissue...

Methods To Detect P53

The detection of p53 in breast cancer can be at the genomic level (DNA), as transcribed messenger RNA, or as the p53 protein (Figure 12.3). Studies of p53 DNA can be classed as looking for mutations or polymorphisms by DNA sequencing, yeast functional assay or Chip-based technology allele loss (LOH) allelic imbalance, resulting in wild-type p53 gene haplo-insufficiency, which can be sufficient to predispose to malignancy. The yeast functional assay uses a reporter system in S cerevisiae and can detect < 10 of breast cancer cells bearing mutant p53 in a tissue sample, supplemented by direct sequencing to locate the precise mutation.44 This combination can point to the functional significance of individual gene mutations but avoids the problem of directly sequencing breast cancer tissue DNA and hence missing mutations where the cancer tissue is outnumbered by normal cells. The clinical utility of the yeast functional assay in predicting response to taxane- or anthracyclin-based...

P53 as a diagnostic marker

Specific p53 mutations are only observed in 15-35 of breast cancers. Mutant p53 as a diagnostic marker for familial breast cancers has been most promising in the Li-Fraumeni syndrome,19 an autosomal dominant familial disorder characterized by the development of bone soft tissue sarcomas, leukemia, adreno-cortical, brain and breast cancers. The expected disease penetrance is 50 by the age of 30 and 90 by the age of 60. Typically, p53 mutation in one allele is accompanied by loss of the other allele (LOH) in the tumors arising in family members. Thus, somatic cells lack normal p53 function, in the Li-Fraumeni patients who have inherited one defective copy of p53.49 For sporadic breast cancer, there is conflicting data on the clinical relevance of polymorphisms in codon 72 of p53.30 For example, an increased risk of developing breast cancer in particular, the arg arg phenotype51 contrasts with an association between the pro pro phenotype with poorer disease-free survival in patients who...

P53 as a predictor for treatment strategy or disease response

Endocrine therapy, systemic chemotherapy and breast radiotherapy have been shown to significantly reduce disease relapse and prolong survival in patients with breast cancer. However, it has not been possible to confidently identify the patients in whom treatment is of benefit or those for whom such treatments ought to be avoided. The function of a number of anticancer agents is directed towards inducing cell death or apoptosis. Loss of normal p53 function can potentially result in relative resistance of breast cancers to chemotherapeutic agents, due to loss of the apoptotic properties of p53. This has been of particular significance in the use of preoperative, neoadjuvant chemotherapy whereby poorer outcome has been observed in those tumors with higher p53 accumulation rates, as demonstrated by immunohistochem-istry,53 while patients with tumors containing wild-type p53 show a more dramatic positive response rate to the preoperative chemother-apy.54 The importance of p53 in response...

P53 as a prognostic factor

Alteration of the p53 gene in breast cancer is associated with an unfavorable prognosis.76-79 Accumulation of nuclear p53, or expression of mutant p53, is associated with a number of histological, biological and clinical adverse prognostic factors including developing metastasis and reduced disease-free survival.80 Microarray approaches have identified a 32-gene expression signature which distinguishes mutant from wild-type p53 and outperforms sequence-based assessment of p53 in predicting prognosis,62 underlining that not all mutations are equal.81 p53 network changes may occur without mutation and the role of p53 in different therapeutic settings may vary. However, p53 overexpression may be a predictor of local recurrence in operable breast cancer.82 p53 aberrations vary between different his-tological types of breast cancers. They are more common in the invasive ductal carcinomas as opposed to lobular carcinomas, and less common in the well-differentiated types with more favorable...

Reactivation of wildtype p53

In the majority of breast cancers where the p53 gene is not mutated, the p53 protein is often kept at very low levels by excessive negative regulation, even under cellular stress. Since MDM-2 binds to and inhibits p53 directly, it has been possible to screen for small molecules which disrupt this binding, leading to reactivated p53. Molecules capable of doing just this have been identified and include the Nutlins,94 potent p53-reactivating molecules, which have been shown to work in vivo by reducing tumor growth in mice xenograft Although the theory of reactivating p53, mutant or wild type, for cancer treatment holds great promise there is a noticeable lack of clinical data, even in breast cancer, to support this as a viable therapeutic avenue at present. A further approach is to explore the differential responses of normal and tumor tissues. Conventional chemotherapy and radiotherapy may be limited by p53-dependent toxicity in normal tissues. Using a small molecule (pifithrin-a),...

Guidelines for HER2 testing

Although published data support the use of FISH for the selection of patients most likely to respond to trastuzumab,20,45,47 the current UK licence for this agent allows the treatment of patients with tumors strongly staining by IHC. Worldwide, there remains an ongoing debate as to whether laboratories should switch to the use of FISH for all specimens, removing the need for a second tier of testing to identify HER2-positive cases, or adopt the two-tier testing strategy currently in use in the UK. Increasingly, FISH testing is seen as the optimal method for determining HER2 status in breast cancer.

Assessment Of Her2 In Breast Core Needle Biopsies

Several reports have shown that the assessment of HER2 status on needle core biopsies (NCBs) in breast cancer is accurate and reliable.62 65 A study of 325 primary breast cancer patients investigated the accuracy of HER2 status using IHC and FISH on NCBs, and compared the result with surgical specimens.66 They found that the accuracy of IHC assessment of HER2 in NCBs was 92 and increased to 96 with additional FISH analysis, which was applied to all strongly positive cases. Therefore, they recommended performing FISH analysis for cases with strong IHC positivity on NCBs in order to minimize the number of false-positive results. Although NCBs have the advantage of good fixation, there can be crushing that makes it difficult to interpret the pattern of staining, and there may be staining at the edge of the cores (edge artefact). In addition, more care should be taken to differentiate between DCIS staining and invasive tumor staining for HER2 in NCBs, and a comparison with hemotoxylin and...

Prognostic significance and association with other prognostic factors

The seminal work by Slamon et al3 in 1987 showed that HER2 gene amplification independently predicted overall survival (OS) and disease-free survival (DFS) in a multivariate analysis in node-positive patients.3 Since then most large studies have confirmed this relationship in multivariate analysis.7,52 Thus, it is now well established that there is a significant correlation between HER2 overexpression amplification and poor prognosis for patients with nodal metastasis. There is, at present, no consensus on the prognostic value of HER2 in node-negative breast cancer patients a group most often diagnosed through screening programs and representing a subgroup which could potentially benefit highly from appropriate adjuvant therapy. Rilke et al67 reported on the prognostic significance of HER2

The stressactivated mitogenactivated protein kinases JNK and p38

As stated above, significant influences on ER and AP-1 signaling may also occur following phosphorylation of the SAPK members Jun kinase (JNK) and p38. While the endpoints of such signaling are likely to be as diverse as for ERK1 2 MAP kinase, as stated above, significant in vitro associations with negative growth regulation in breast cancer cells have been reported for JNK and p38.16,17,53 If represented in clinical breast cancer, therefore, JNK and p38 signaling would perhaps be predicted to substantially impact on patient prognosis and endocrine response in a manner diametrically opposed to pMAP kinase. Again, our studies immunocytochemically employing phospho-specific antibodies for JNK and p38 in clinical breast cancer have proved interesting in this regard.128 We noted that nuclear activation of JNK or p38 was not uncommon within clinical breast cancer (Figure 10.3).

Smaller tumors are less frequently node-positive than larger lesions, but there is a risk of metastatic lymph node disease even for lesions < 10 mm in size Carter et al9 reported nodal metastases in approximately 20 of patients with breast cancers < 10 mm. Some have reported that 12 of breast carcinomas < 5 mm in diameter are associated with lymph node metastases,10 whilst others have suggested that nodal metastases are unlikely in tumors of this size range.11 Because of the clear prognostic significance of breast cancer size, it is one of the lynchpins of data collection for radiology quality assurance (QA) in mammographic breast screening programs. Specifically, it is recommended that half of the invasive carcinomas detected by mammo-graphic screening in the UK National Health Service Breast Screening Programme should be < 15 mm in size. It is, therefore, essential for QA of breast screening programs that pathol-ogists measure tumors as accurately as possible to the nearest...

The Prognostic Impact Of Nodal Micrometastases

The prognostic impact of micrometastases in breast cancer is largely disputed. Some authors found no survival disadvantage for micrometastatic nodal involvement others have reported a worse associated outcome, but only for disease-free survival and not for overall survival and still others described a definite disadvantage (Table 6.1). Occult metastases are often admixed with micro-metastases in the quoted studies, especially in the earlier ones. The methods of pathological evaluation are also different from study to study and many would be considered less than optimal with our current knowledge most studies were aimed at detecting some occult metastases and were not devised to exclude all occult metastases of a given size. It is likely that no attempt was ever made to exclude the possibility of the identified micrometastases being the tip of a larger metastasis iceberg (Figure 6.3). As shown in Table 6.1, the micrometastatic group often comprised only a few cases and the follow-up...

Endocrine Resistance And Biology Of The Estrogen Receptor Function

As resistance to endocrine therapy is one of the main challenges in the treatment of ERpositive breast cancer, understanding such processes is of major importance. In particular, deciphering the biology of the ER function, and the proteins which participate in estrogen signaling, it is hoped to improve our knowledge of the events which cause a response to endocrine therapy and thus identify accurate predictive markers for responsiveness to treatment. In early studies, ER was identified as a transcription factor regulating the expression of specific genes in the nucleus. Some of these genes are important in breast physiology, and others for the proliferation and survival of breast cancer cells. This estrogen-mediated action in the nucleus is termed nuclear-initiated steroid signaling (NISS), or genomic activity of the ER. Recent evidence also suggests that estrogen can bind ERs located in or near the plasma membrane and rapidly activate other signaling pathways. This is called...

Background

The baseline evidence for the variation in breast cancer behavior comes from studies from many years ago of women who had no treatment and of those that were before the advent of systemic (i.e. adjuvant) treatment following surgery. Bloom et al1 reported on a series of 250 women seen at the Middlesex Hospital, London, UK between 1805 and 1933 74 had advanced (stage IV) disease at the time of admission but 18 of these were still alive at 5 years without any treatment. The number of patients is small but this demonstrates the variation in the natural history of untreated breast cancer. The importance of having large series of patients to derive valid information was appreciated it is from pre-adjuvant therapy studies that amassed information from one or more centers that data on the clinical importance of tumor size and node status comes.2-7 A criticism of some of the studies, e.g. The National Cancer Institute Surveillance, Epidemiology and End Results (SEER) Program,7 is that staging...

Conclusions

At present, the histological features of greatest weight in predicting the behavior of primary breast carcinomas are lymph node stage, histological grade and tumor size, and the presence of lymphovascular invasion. When combined, with each other and with clinical data, they can be used as a basis for selection of the most appropriate treatments, both surgical and systemic. Additional predictive markers provide invaluable information in the choice of the optimum treatment for patients with breast cancer who require adjuvant therapy. The assessment of ER status is essential in avoiding a time delay for patients who are unlikely to respond to hormone treatments, and patients with tumors that are HER2 negative will not benefit from trastuzumab. In summary, the histopathologist has a major role to play, not only in the diagnosis of breast cancer but in forming a part of the multidisciplinary management team, and providing vital prognostic and predictive data to enable the patient to...

Summary

From the different methods available to assess proliferative activity in breast cancer, the MAI meets the criteria of well-established prospective prognostic value, stable thresholds, good repro-ducibility and practicality. It can therefore be used to stratify patients for adjuvant therapy. The Ki67 labeling index assessed with the MIB1 antibody is a good runner-up, and may become clinically applicable after further methodological Figure 3.2 Survival of lymph node-negative breast cancer patients with low and high mitotic activity index (MAI) prospective results from the Dutch MMCP study.85 Cyclin A is expressed in the late phases of the cell cycle, and may thereby function as a marker of proliferating cells. The cyclin A labeling index (not influenced by amplification152) is indeed positively correlated with proliferation.59 In a few breast cancer studies, a high cyclin A labeling index was associated with poor Overexpression of cyclin D1 in invasive breast cancers occurs in 40-50 of...

Genomic mechanisms

Classically, the ER functions as a transcription factor within the nucleus, and the ability of estrogen antiestrogens to regulate gene expression has been extensively investigated in experimental models of human breast cancer both in vitro and in vivo. Based on these studies, it is becoming increasingly evident that estrogens can promote the autocrine expression of growth factor signaling pathway elements (Figure 10.2, 2a)44,45 - notably components of the EGFR and insulin-like growth factor receptor (IGF-1R) pathways - in estrogen-responsive and -dependent human breast cancer cell lines.41 48 In the latter instance, the IGF-1R has also been shown to be activated by estrogen, subsequently recruiting downstream signaling components, notably including insulin receptor substrate-1 (IRS-1), which in turn may be estro-genregulated.46,49 Such actions, which are often antagonized by antiestrogens, could significantly supplement the cellular growth responses directly primed by...

Apoptosis

Within the proline-rich domain of p53, there is a polymorphism at codon 72 (pro arg), which correlates with the apoptotic potential of the p53 proteins and their affinity for localizing to the mitochondrial outer membrane.18 The importance of this proline-rich region in mediating apoptosis independent of p53 sequence-specific transactivation has been particularly highlighted in Li-Fraumeni19 patients where a germ-line mutation within this region (proline-82) has been clearly identified and characterized, and in which female members have a high risk of breast cancer.

MDM2 as an oncogene

The oncogenic properties of MDM-2 were further suggested in a range of tumor types including breast cancers,22 where overexpression of MDM-2 was found either through gene amplification, increased transcription, or increased translation. In some individuals with Li-Fraumeni syndrome, who have two alleles of p53 without the capacity to express p21, show overexpression of MDM-2 in their normal tissues. Overexpression of MDM-2 in the absence of p21 expression (which is tran-scriptionally induced by p53) suggests that MDM-2 overexpression is p53 independent and may be a direct cause of the high tumor incidence (including breast cancer) in these families.34

Mouse Double Minute4

MDM-4 (MDMX) was identified as a binding partner of p53 and shows structural homology to MDM-2, and is thus a potentially important regulator of p53. When bound to p53 it inhibits p53 transactivation, but does not appear to target p53 for degradation as it lacks the E3 ubiquitin ligase function of MDM-2. MDMX overexpression can protect p53 from MDM-2-mediated degradation while still maintaining suppression of p53 transactivation.35 The gene for MDMX is overexpressed or amplified in 10-20 of diverse tumor types including breast cancer.27 Like MDM-2, MDMX knockout mice are embryonic lethal, although this can be rescued by being in a p53-deficient background. It has been suggested that to fully activate p53 both MDM-2 and MDMX need to be inactivated, which adds another level of complexity when trying to discover ways of exploiting p53 for therapeutic gain.

Gene therapy

The addition of the wild-type p53 gene back into tumors which have mutated p53 or which are null for p53 is possible by the use of gene therapy. Using virus-based vectors which are replication defective it has been possible to demonstrate a significant clinical effect of stabilizing tumor growth or causing tumor regression in a fraction of patients with no significant toxicity.87 This form of gene therapy has been tested in clinical trials in a range of cancers based on the concept that the combined use of these vectors with chemotherapy or radiotherapy may have an enhanced clinical effect.86 One recent phase II trial of intratumoral adenoviral vector containing wild-type p53 (AdCMV-p53) combined with chemotherapy88 has shown enhanced p53 activity, local immunomodulatory effects and objective clinical response in locally advanced breast cancer.

Immunotherapy

The altered proteins coded by mutant p53 can potentially be used as targets for the immune system, which if recognized accurately could provide a nontoxic tumor specific treatment. Most of the in vivo work in this area has been carried out on mice and the potential of using this treatment in human cancers, in a way analogous to growth factor receptor therapies such as Lapatanib and Herceptin, has yet to be explored.102 One promising phase II trial of vaccination with p53 peptide pulsed dendritic cells did result in associated with disease stabilization in 40 of patients with p53 expression in advanced breast cancer.103

Endocrine therapy

Transfection of normal breast cancer cells with the HER2 gene has been shown to result in acquisition of estrogen-independent growth which is insensitive to tamoxifen.80,81 A number of clinical studies, using various endpoints, have reported an association between HER2 positivity and resistance to endocrine therapy.82-84 Some reports have described specific resistance to tamoxifen in HER2-overex-pressing tumors.8284 The recently reported 20-year update of the Naples GUN Trial82 Several studies have also shown a reduction in response rates to endocrine therapy. Metastatic breast cancer which overexpressed HER2, measured by high plasma levels of the extracellular domain, demonstrated a substantial reduction in response rate to endocrine therapy.85 Cheung et al86 have examined marker levels CA 15.3, CEA, ESR and serum HER2 in 15 patients receiving docetaxel-based regimes from two multicenter trials. Measurement of serum HER2 showed a correlation with tissue HER2 (Herceptest) in the...

Immunotoxins

And toxins, and have allowed construction via gene fusion of recombinant molecules which combine antibody-mediated recognition of tumor cells with specific delivery of potent protein toxins of bacterial or plant origin. Therefore, antibodies to HER2 may also be able to play a role as vehicles for the targeting of therapeutic agents to cancers. Immuno-toxins have been constructed with various anti-HER2 antibodies which have been coupled to Lys-PE40, a recombinant form of Pseudomonas exotoxin.126 The ligands in the erbB family have also been studied as potential carriers, utilizing their binding affinity to respective receptors. Complete regression of human breast cancer xenografts in nude mice was seen when a fusion toxin of NRG 1 was adminis-tered.127 A bispecific toxin of an anti-HER2 antibody and transforming growth factor-a also inhibited the growth of breast cancer cells in vivo.128 Antibody targeting of drug-loaded liposomes has also been investigated as a vehicle for drug...

Conclusion

HER2 is an oncoprotein which is overex-pressed in about 20 of breast cancers, almost universally as a consequence of gene amplification. HER2 can be used as a prognostic factor, may be predictive of response to systemic chemotherapy, but is clearly predictive for response to Herceptin. It is therefore imperative that reliable and simple assays are implemented into routine practice in most hospital settings. Standardization of such assays, as well as uniform scoring systems, must be adhered to for accurate diagnosis of

Cellcell adhesion

Epithelial cells mediate intercellular adhesion primarily through adherens junctions, desmo-somes, and gap junctions. The molecules involved in these adhesive complexes - classical cadherins, desmosomal glycoproteins and connexins, respectively - have all been shown to exhibit altered expression in breast cancers. The classical cadherins include E-cadherin, P-cadherin and N-cadherin, and of these the major focus in breast cancer has been E-cad-herin. E-cadherin mediates homophilic Ca++-dependent adhesion and, via interactions with cytoplasmic catenins and the actin cytoskeleton, it plays an important role in maintaining epithelial morphogenesis.1 There is compelling evidence to indicate that E-cadherin acts as a tumor suppressor in vitro studies have indicated an invasion-suppressor role for E-cadherin,2,3 whilst loss of heterozygosity (LOH) at this site is frequently detected in breast carcinomas,4 and hypermethylation of the E-cadherin promoter region, with reduced expression of the...

The Genetics of Pancreatic Cancer

Based on family aggregation and family history of pancreatic disease, it is estimated that around 10 of cases diagnosed with pancreatic cancer host a hereditary germ line mutation (Lynch et al., 1996 Hruban et al., 1998). Furthermore, it has been observed that pancreatic cancer occurs in excess of expected frequencies, in several familial cancer syndromes, which are associated with specific germ-line mutations. The best characterized include hereditary breast-ovarian cancer syndrome ascribed to mutations in BRCA1 2 genes, especially BRCA2 familial pancreatic and breast cancer syndrome due to mutations in PALB2 gene familial isolated pancreatic cancer caused by mutations in PALLD encoding palladin and familial multiple mole melanoma with pancreatic cancer (FAMMM-PC) attributed to Li-Fraumeni syndrome is a rare, clinically and genetically heterogeneous, inherited cancer syndrome caused by germline mutations in TP53. Li-Fraumeni syndrome is characterized by autosomal dominant inheritance...

An Ounce of Prevention

Diets high in fat also may have a negative effect on breast cancer survival rates. According to the Physicians Committee for Responsible Medicine, one reason is that foods affect the action of hormones in the body, as well as the strength of the immune system. For instance, several of the more common types of cancer, such as cancer of the breast, ovary, uterus, and prostate, are linked to sex hormones. In large part, the amount of hormones in our bodies and their actions are determined by the foods we eat. High-fat diets can set you up for an increased risk of breast cancer, because fats increase the amount of estrogen in the blood. Estrogen stimulates breast cells in such a way that cancer is more likely to occur and is more aggressive. Plus, diets high in fatty foods lead to obesity, which also causes higher estrogen levels in the blood. However, if you ask any doctor what you should do in order to prevent breast cancer, the response will most likely be to get an annual mammogram,...

Why consider fatigue in cancer

Cancer is characterized by multiple symptoms, caused by the primary tumour, metastasis, and the side-effects of treatment, be it surgery, radiotherapy, or chemotherapy. Symptoms also result from the emotional, social, and spiritual effects of cancer and its treatment. They can also be caused by, or exacerbate, pre-existing illness, especially in older people who may have other chronic conditions. Sometimes symptoms can be devastating. Suffering can extend beyond the person directly affected to family members, friends, and anyone involved in caring for the person.
