In March, 2010, a group of breast cancer experts met to develop a consensus statement on breast cancer prevention, with a focus on medical and therapeutic interventions. We present the conclusions in this Review. First we agreed that the term chemoprevention is inappropriate and suggested that the term preventive therapy better represents this feature of management. ⋯ Other agents, such as aspirin, other non-steroidal anti-inflammatory drugs, COX-2 inhibitors, retinoids, rexinoids, and dietary components have limited effects or are in the early phases of investigation. New contralateral tumours in women with breast cancer might be generally useful as a model for prevention, as has been seen for tamoxifen. If valid such a model would facilitate the design of simpler, cheaper, and better-focused trials for assessing new agents.

ReviewDefinition and classification of cancer cachexia: an international consensus.
To develop a framework for the definition and classification of cancer cachexia a panel of experts participated in a formal consensus process, including focus groups and two Delphi rounds. Cancer cachexia was defined as a multifactorial syndrome defined by an ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support and leads to progressive functional impairment. Its pathophysiology is characterised by a negative protein and energy balance driven by a variable combination of reduced food intake and abnormal metabolism. ⋯ Assessment for classification and clinical management should include the following domains: anorexia or reduced food intake, catabolic drive, muscle mass and strength, functional and psychosocial impairment. Consensus exists on a framework for the definition and classification of cancer cachexia. After validation, this should aid clinical trial design, development of practice guidelines, and, eventually, routine clinical management.

Randomized Controlled Trial Multicenter Study Comparative StudySubcutaneous versus intravenous administration of bortezomib in patients with relapsed multiple myeloma: a randomised, phase 3, non-inferiority study.
Intravenous injection is the standard administration route of bortezomib; however, subcutaneous administration is an important alternative. We compared the efficacy and safety of subcutaneous versus intravenous bortezomib at the approved 1·3 mg/m(2) dose and twice per week schedule in patients with relapsed multiple myeloma. ⋯ Johnson & Johnson Pharmaceutical Research and Development, and Millennium Pharmaceuticals.

Review Meta AnalysisGenetic variants associated with breast-cancer risk: comprehensive research synopsis, meta-analysis, and epidemiological evidence.
More than 1000 reports have been published in the past two decades on associations between variants in candidate genes and risk of breast cancer. Results have been generally inconsistent. We did a literature search and meta-analyses to provide a synopsis of the current understanding of the genetic architecture of breast-cancer risk. ⋯ US National Cancer Institute.

Randomized Controlled TrialShort-term neoadjuvant androgen deprivation and radiotherapy for locally advanced prostate cancer: 10-year data from the TROG 96.01 randomised trial.
The TROG 96.01 trial assessed whether 3-month and 6-month short-term neoadjuvant androgen deprivation therapy (NADT) decreases clinical progression and mortality after radiotherapy for locally advanced prostate cancer. Here we report the 10-year results. ⋯ Australian Government National Health and Medical Research Council, Hunter Medical Research Institute, AstraZeneca, and Schering-Plough.
