Once castration resistance is documented and secondary hormone therapy is ineffective, standard treatment of metastatic prostate cancer is docetaxel, with bisphosphonates and radiopharmaceuticals administered to treat bone symptoms. To improve outcomes, numerous studies have evaluated docetaxel in combination with other agents. Here, results for docetaxel-based combination therapy in castration-resistant prostate cancer (CRPC) are reviewed. ⋯ Docetaxel-based doublet therapy remains an active investigational strategy in CRPC. Further phase III data are awaited to determine whether survival can be extended compared with docetaxel alone.

The results of the recently published large European randomised study in rectal cancer (European Organisation for Research and Treatment of Cancer 22921 trial) do not support current guidelines recommending postoperative chemotherapy for patients who have previously undergone preoperative radiochemotherapy or radiotherapy [radio(chemo)therapy]. To evaluate this discrepancy further, a systematic review of relevant randomised trials was undertaken. ⋯ To resolve the issue in question, a meta-analysis of relevant studies is required, and new trials should be launched to explore new drug combinations against observation. Currently, delivery of adjuvant chemotherapy in patients undergoing preoperative radio(chemo)therapy is not evidence based.

The preferred and actual participation roles during decision making have been studied over the past two decades; however, there is a lack of evidence on the degree of match between patients' preferred and actual participation roles during decision making. A systematic review was carried out to identify published studies that examined preferred and actual participation roles and the match between preferred and actual roles in decision making among patients with cancer. PubMed (1966 to January 2009), PsycINFO (1967 to January 2009), and CINAHL (1982 to January 2009) databases were searched to access relevant medical, psychological, and nursing literature. ⋯ Research to date documents a pervasive mismatch between patients' preferred and actual roles during decision making. Yet, there is lack of innovative interventions that can potentially increase matching of patients' preferred and actual role during decision making. Role preferences are dynamic and vary greatly during decision making, requiring regular clinical assessment to meet patients' expectations and improve satisfaction with treatment decisions.
