Randomized Controlled TrialPembrolizumab versus chemotherapy for microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer (KEYNOTE-177): final analysis of a randomised, open-label, phase 3 study.
Pembrolizumab has shown improved progression-free survival versus chemotherapy in patients with newly diagnosed microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer. However, the treatment's effect on overall survival in this cohort of patients was unknown. Here, we present the final overall survival analysis of the KEYNOTE-177 study. ⋯ MSD.

ReviewTime to deterioration of symptoms or function using patient-reported outcomes in cancer trials.
Time-to-event endpoints for patient-reported outcomes, such as time to deterioration of symptoms or function, are frequently used in cancer clinical trials. Although time-to-deterioration endpoints might seem familiar to cancer researchers for being similar to survival or disease-progression endpoints, there are unique considerations associated with their use. ⋯ Challenges including the consideration of intercurrent events, the difficulty in maintaining adequate completion rates, and considerable patient and trial burden from long-term, serial, patient-reported outcome measurements render time to deterioration a problematic approach for widespread use. For trials in which a comparative benefit in symptoms or function is an objective, an analysis at pre-specified relevant timepoints could be a better approach.

Multicenter StudyPrimary radiotherapy and deep inferior epigastric perforator flap reconstruction for patients with breast cancer (PRADA): a multicentre, prospective, non-randomised, feasibility study.
Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. However, evidence for this treatment sequence is sparse. We aimed to explore the feasibility of preoperative radiotherapy followed by skin-sparing mastectomy and deep inferior epigastric perforator (DIEP) flap reconstruction in patients with breast cancer requiring mastectomy. ⋯ Cancer Research UK, National Institute for Health Research.

ReviewEquity in national cancer control plans in the region of the Americas.
Many social determinants that are outside an individual's control affect their exposure to cancer risk factors and access to high-quality care. There is increasing recognition that national cancer control plans are fundamental tools to address cancer burden and promote equitable care. To investigate how policies in the WHO region of the Americas promote equity in cancer care, we evaluated 46 cancer-related health plans covering 34 countries. ⋯ Our results suggest that equity is not sufficiently integrated in national cancer control plans in the region. 17 documents defined inequity as a problem mainly related to difficulties in the access to care. Although 25 countries had designed equitable interventions, none had dedicated a budget for their implementation. Countries still need to translate their expressed concern with equity in health into funded, targeted interventions that accompany patients throughout the entire cancer care continuum.
