Randomized Controlled TrialEfficacy and safety of radium-223 dichloride in patients with castration-resistant prostate cancer and symptomatic bone metastases, with or without previous docetaxel use: a prespecified subgroup analysis from the randomised, double-blind, phase 3 ALSYMPCA trial.
Primary results from the phase 3 ALSYMPCA trial showed that radium-223 dichloride (radium-223), a targeted α-emitter, improved overall survival compared with placebo and was well tolerated in patients with castration-resistant prostate cancer and symptomatic bone metastases. We did a prespecified subgroup analysis from ALSYMPCA to assess the effect of previous docetaxel use on the efficacy and safety of radium-223. ⋯ Algeta ASA and Bayer HealthCare Pharmaceuticals.

ReviewThe biological and clinical effects of smoking by patients with cancer and strategies to implement evidence-based tobacco cessation support.
Tobacco use is an established risk factor for the development of several cancers; however, far less work has been done to understand the effects of continued smoking on cancer treatment outcomes, and structured tobacco cessation efforts are not well incorporated into the standard care for patients with cancer. In this Review we discuss the known biological effects of smoking on cancer cell biology and emphasise the clinical effects of continued smoking in patients with cancer treated with chemotherapy or radiotherapy. Although evidence supports the need for inclusion of dedicated tobacco cessation efforts for patients with cancer, clinicians should consider the methods used to provide evidence-based tobacco cessation support and the available resources to deliver and maintain consistent tobacco cessation support. We also address the variables to consider in the design and implementation of a sustainable tobacco cessation programme.

ReviewInternational Myeloma Working Group updated criteria for the diagnosis of multiple myeloma.
This International Myeloma Working Group consensus updates the disease definition of multiple myeloma to include validated biomarkers in addition to existing requirements of attributable CRAB features (hypercalcaemia, renal failure, anaemia, and bone lesions). These changes are based on the identification of biomarkers associated with near inevitable development of CRAB features in patients who would otherwise be regarded as having smouldering multiple myeloma. ⋯ Finally, we provide specific metrics that new biomarkers should meet for inclusion in the disease definition. The International Myeloma Working Group recommends the implementation of these criteria in routine practice and in future clinical trials, and recommends that future studies analyse any differences in outcome that might occur as a result of the new disease definition.

Randomized Controlled TrialLung cancer probability in patients with CT-detected pulmonary nodules: a prespecified analysis of data from the NELSON trial of low-dose CT screening.
The main challenge in CT screening for lung cancer is the high prevalence of pulmonary nodules and the relatively low incidence of lung cancer. Management protocols use thresholds for nodule size and growth rate to determine which nodules require additional diagnostic procedures, but these should be based on individuals' probabilities of developing lung cancer. In this prespecified analysis, using data from the NELSON CT screening trial, we aimed to quantify how nodule diameter, volume, and volume doubling time affect the probability of developing lung cancer within 2 years of a CT scan, and to propose and evaluate thresholds for management protocols. ⋯ Zorgonderzoek Nederland Medische Wetenschappen and Koningin Wilhelmina Fonds.

ReviewEffect of HIV infection on the outcome of cancer therapy in children.
Systematic studies comparing the outcomes of cancer treatment between children with and without HIV are scarce. The literature seems to suggest that, even with present therapeutic advances, prognosis is poor with HIV infection. The aim of this Review was to assess scientific publications from 1990 to present, addressing the difficulties associated with treatment of cancer in children with AIDS and the adaptive changes in therapy. Although much progress has been achieved, further research is needed about antiretroviral and cytotoxic drug interactions, the optimum use of supportive therapy including stem cells and bone marrow transplant, the timing of the initiation of highly active antiretroviral therapy, and the optimum use of protease inhibitors.
