Along with anthracyclines, taxanes are the most active cytotoxics in breast cancer (BC). Balancing efficacy against toxicity in older patients with reduced physiological reserves and significant comorbidities is both important and difficult. This is especially so given the under-representation of elderly patients in major trials and a consequent lack of evidence for drug, dose and schedule. However, BC is frequent in elderly women, who are a growing proportion of the population. Careful consideration of their care is therefore imperative. Treatment that can cure or extend the duration and quality of life should not be restricted by age, but needs to be tailored to the circumstances of elderly patients. In adjuvant use, taxane toxicity in older women is greater than in their younger counterparts, limiting its sequential combination with anthracyclines for high-risk disease unless patients are in very good health. More frequently taxanes are used alone (weekly paclitaxel, three-weekly docetaxel) or combined with cytotoxics other than anthracyclines (e.g. docetaxel plus cyclophosphamide) to reduce cardiac risk, especially in HER-2-positive patients who may develop additional trastuzumab-related cardiac events. In elderly patients with metastases, weekly paclitaxel and three-weekly docetaxel are among the cornerstones of treatment, with generally acceptable toxicity. Three-weekly docetaxel at the approved dose of 100 mg/m2 is not appropriate for the elderly. Nab-paclitaxel has efficacy comparable with solvent-based taxanes without need for steroid premedication but has been little studied in older BC patients. A head-to-head comparison with weekly paclitaxel favoured the solvent-free formulation for pathologic response, but those studied were a general adult population. Compared with early stage disease, choice of taxane and regimen in the metastatic setting relies even more on availability and preferences with regard to schedule, toxicity profile and cost, especially for recently developed formulations. © 2015 Elsevier Ltd.

To better support women with breast cancer during their treatment phase, supportive care offer and organization were modified. This is the result of new needs and the new organization of the patient’s follow-up between hospital and general practice care. Patient–doctor dialog involved especially in the development of therapeutic education. Also, patient’s abilities are motivated to manage for the best an illness which became chronic. Progressively, to fulfill the patient’s wishes to be leaded to a more global medical care, the offer in supportive care has changed to a wider concept of “self care”. © 2016, Springer-Verlag France.

As the mean age of the global population increases, breast cancer in older individuals will be increasingly encountered in clinical practice. Management decisions should not be based on age alone. Establishing recommendations for management of older individuals with breast cancer is challenging because of very limited level 1 evidence in this heterogeneous population. In 2007, the International Society of Geriatric Oncology (SIOG) created a task force to provide evidence-based recommendations for the management of breast cancer in elderly individuals. In 2010, a multidisciplinary SIOG and European Society of Breast Cancer Specialists (EUSOMA) task force gathered to expand and update the 2007 recommendations. The recommendations were expanded to include geriatric assessment, competing causes of mortality, ductal carcinoma in situ, drug safety and compliance, patient preferences, barriers to treatment, and male breast cancer. Recommendations were updated for screening, primary endocrine therapy, surgery, radiotherapy, neoadjuvant and adjuvant systemic therapy, and metastatic breast cancer. © 2012 Elsevier Ltd. Source

Background: Bevacizumab and trastuzumab are efficacious for treatment of advanced or HER2-positive metastatic breast cancer; however, few data exist for this regimen in inflammatory breast cancer. In our phase 2 trial, we aimed to assess efficacy and safety of neoadjuvant bevacizumab combined with trastuzumab and chemotherapy in patients with primary HER2-positive inflammatory breast cancer. Methods: In our phase 2, multicentre, open-label, single-arm, non-comparative trial, we enrolled women (aged ≥18 years) with histologically confirmed HER2-positive non-metastatic inflammatory breast cancer at private or public oncology centres in France. Before surgery, patients were treated with fluorouracil, epirubicin, cyclophosphamide, and bevacizumab (cycles 1-4) and docetaxel, bevacizumab, and trastuzumab (cycles 5-8) in 3-week cycles. After surgery, patients received adjuvant radiotherapy, trastuzumab, and bevacizumab. For the primary endpoint, we assessed the proportion of patients who achieved a pathological complete response (defined by central review of surgical specimens according to Sataloff classification, counting missing data as failure) and adverse events in all enrolled patients. This study is registered with . ClinicalTrials.gov, number . NCT00717405. Findings: Between Oct 23, 2008, and Oct 28, 2009, we enrolled 52 patients at 21 centres. 42 (81%) of 52 patients received all eight cycles of neoadjuvant therapy and 49 (94%) underwent surgery. After neoadjuvant therapy, 33 of 52 patients had a pathological complete response according to central review (63·5%, 95% CI 49·4-77·5). The most common adverse events were asthenia and nausea (both occurred in 36 [69%] of 52 patients). 25 (48%) patients had grade 3-4 neutropenia, which was the most common grade 3-4 adverse event. Only one grade 3 or worse adverse event regarded as related to bevacizumab was reported (hypertension, one patient). Four patients (8%) had cardiac failure. Interpretation: Neoadjuvant treatment with bevacizumab, trastuzumab, and chemotherapy was efficacious and well tolerated in patients with previously untreated primary inflammatory breast cancer. Further confirmation of use of bevacizumab in inflammatory breast cancer is needed. Funding: Roche (France). © 2012 Elsevier Ltd. Source

Both epigenetic and splicing regulation contribute to tumor progression, but the potential links between these two levels of gene-expression regulation in pathogenesis are not well understood. Here, we report that the mouse and human RNA helicases Ddx17 and Ddx5 contribute to tumor-cell invasiveness by regulating alternative splicing of several DNA-and chromatin-binding factors, including the macroH2A1 histone. We show that macroH2A1 splicing isoforms differentially regulate the transcription of a set of genes involved in redox metabolism. In particular, the SOD3 gene that encodes the extracellular superoxide dismutase and plays a part in cell migration is regulated in an opposite manner by macroH2A1 splicing isoforms. These findings reveal a new regulatory pathway in which splicing factors control the expression of histone variant isoforms that in turn drive a transcription program to switch tumor cells to an invasive phenotype. © 2012 Nature America, Inc.
