Abstract: PURPOSE To update the 2002 American Society of Clinical Oncology guideline on pharmacologic interventions for breast cancer (BC) risk reduction. METHODS A literature search identified relevant randomized trials published since 2002. Primary outcome of interest was BC incidence (invasive and noninvasive). Secondary outcomes included BC mortality, adverse events, and net health benefits. An expert panel reviewed the literature and developed updated consensus guidelines. Results Seventeen articles met inclusion criteria. In premenopausal women, tamoxifen for 5 years reduces the risk of BC for at least 10 years, particularly estrogen receptor (ER) -positive invasive tumors. Women < or = 50 years of age experience fewer serious side effects. Vascular and vasomotor events do not persist post-treatment across all ages. In postmenopausal women, raloxifene and tamoxifen reduce the risk of ER-positive invasive BC with equal efficacy. Raloxifene is associated with a lower risk of thromboembolic disease, benign uterine conditions, and cataracts than tamoxifen in postmenopausal women. No evidence exists establishing whether a reduction in BC risk from either agent translates into reduced BC mortality. Recommendations In women at increased risk for BC, tamoxifen (20 mg/d for 5 years) may be offered to reduce the risk of invasive ER-positive BC, with benefits for at least 10 years. In postmenopausal women, raloxifene (60 mg/d for 5 years) may also be considered. Use of aromatase inhibitors, fenretinide, or other selective estrogen receptor modulators to lower BC risk is not recommended outside of a clinical trial. Discussion of risks and benefits of preventive agents by health providers is critical to patient decision making.

Abstract: It is well known that different pathologists in different laboratories follow different protocols for the processing and examination of these specimens. There is also extensive literature (some of which is summarized in the references appended to the present report) on the likelihood of identifying metastases of varying sizes with different methods of preparation, as well as on the clinical significance of this identification, which varies not only from site to site but also from report to report on the same site. The Association of Directors of Anatomic and Surgical Pathology (ADASP) has reviewed this literature as well as the personal experience of its own members to present a set of recommendations for lymph node biopsies, lymph node dissections, sentinel node biopsies, lymph node fine needle aspiration (FNA) and core needle biopsies. It should be noted that these recommendations are intended specifically for lymph nodes being studied for metastatic neoplasms, and are not intended to apply to lymph nodes being evaluated for lymphoma, infections, and other disease processes. They are, however, formulated generically enough to apply regardless of whether the primary tumor is a carcinoma of the breast, carcinoma of the prostate, melanoma, or any other malignant, potentially metastasizing tumor. The Association has published numerous documents with recommendations for reporting surgical pathology specimens involving particular organ sites (for example, breast, pancreas, thyroid, etc.) However, the Association has not yet considered the generic question of dealing with lymph node specimens in which the intent is to search for and document the presence of metastatic disease. We are also unaware of guidelines for pathologists published by any other organization on this subject.

Abstract: The optimal duration of cytostatic treatment for metastatic breast cancer is still a matter of debate. Possible gain in the duration of remission has to be weighed against the side-effects of treatment. Our aim was to define the optimal duration of cyclophosphamide, methotrexate, 5-fluorouracil (CMF) treatment by studying the time to treatment failure, overall survival and using a Q-TWiST analysis. The treating physician's opinion was asked. The European Organization for Research and Treatment of Cancer (EORTC) Breast Cancer Group conducted a randomised trial in 204 non-progressing metastatic breast cancer patients after induction chemotherapy (CMF) to stop or continue treatment. Progression-free (PFS) and overall survival (OS) were studied. To gain more insight into the burden of treatment-related side-effects, Q-TWiST was analysed. In addition, we asked for oncologists' preferences as patients are likely to be influenced by their physicians' opinion. Continuation of CMF had a significantly longer time to treatment failure (TTF) 5.2 versus 3.5 months (P=0.011). There was no overall survival (OS) difference 14.0 versus 14.4 months (P=0.77). Mean quality-adjusted survival time was equal to 8.4 months for no further treatment and decreased to 7.9 months for continuation of CMF (95% Confidence Interval (CI) of difference equals 0.5+/-2.5 months). Almost half of the oncologists said they would favour continuous treatment for a 3-month gain in time to progression-a difference which was not found in this study. Based on these data, an interruption of chemotherapy (CMF), if this is the wish of the patient, is justified.

Abstract: BACKGROUND: In Western countries, breast cancer incidence and mortality are higher than in Mediterranean countries. These differences have been ascribed to environmental factors but also to late-stage diagnostic and biological specific characteristics. PATIENTS AND METHODS: Between September 2002 and September 2005, we collected clinical data by phone counselling 180 French and Mediterranean breast cancer patients and performed microarray experiments. RESULTS: Characteristics of breast cancer in patients from Lebanon, Tunisia and Morocco were more aggressive (more SBR grade III and positive node invasion) and patients were 10 years younger at diagnosis. Sixteen differentially expressed genes such as MMP9, VEGF, PHB1, BRCA1, TFAP2C, GJA1 and TFF1 were also found. Additionally, an up-regulation of cytokeratins KRT8 and KRT18 may indicate a luminal B subtype in "South" (Lebanon, Tunisia and Morocco) tumors while "North" (France) tumors may more frequently be luminal A type. CONCLUSION: This study allowed the identification of specific clinical and transcriptomic parameters in patients from South Mediterranean countries.

Abstract: This paper summarises the population-based major trends in cancer incidence and mortality in the period 1989-1998 in The Netherlands. Trends of the European age-adjusted incidence and mortality rates were estimated by the Estimated Annual Percentage Change (EAPC) method. Increases in incidence were found for cancer of the breast and lung for females. For males, an increase was observed for cancer of the prostate, colon, rectum and testis. In both groups, oesophageal and pharyngeal cancer increased, but that of stomach and gallbladder cancer decreased. The main increases in mortality were found for pharyngeal cancer in males, lung in females and oesophageal cancer in both sexes. Decreases were shown for stomach cancer for both sexes and lung cancer for males. Trends in incidence may be a result of changes in behaviour, smoking habits in preceding decades are related to the increase in lung cancer for females, and early detection, screening programmes increased the incidence for breast and prostate cancers. Decreases in mortality may be related to more successful treatment of leukaemia, Hodgkin's lymphoma, colorectal and testicular cancers. Primary prevention of cancer remains important.
