Impact of exercise on health outcomes in people with cancer: an umbrella review of systematic reviews and meta-analyses of randomised controlled trials

January 31, 2026

Comment: This synthesis of 80 meta-analyses corrects the long-standing bias that favors high-intensity aerobic training over more accessible, multi-systemic interventions. While aerobic fitness remains a vital component of recovery, this review highlights that Tai Chi and Qigong are clinically efficacious for preserving functional independence and psychological resilience. These modalities offer high-value interventions for addressing treatment-related […]

Comment: A central issue in palliative oncology is the historical focus on aggressive salvage therapies that frequently lead to negative impacts on QOL rather than measurable survival gains. Metronomic capecitabine reverses this risk-benefit calculation, delivering a median overall survival of 18 months in responders while reporting no treatment-related deaths or severe toxicities. In a population […]

Comment: The primary disconnect in this data is the dramatic, nearly five-fold reduction in local-regional recurrence that fails to translate into a statistically significant overall survival benefit for the general cohort. While a 10-year local recurrence rate of 11% compared to 22% is a clear victory for regional management, the P=.063 for overall survival reminds […]

Precautions for breast cancer-related lymphoedema: risk from air travel, ipsilateral arm blood pressure measurements, skin puncture, extreme temperatures, and cellulitis

| Cancer - Breast, Mastectomy-Lumpectomy

Comment: This synthesis serves as a robust rebuttal to the long-standing “precautions” that have dominated lymphedema education. The findings demonstrate that most traditional prohibitions—specifically air travel and blood pressure measurements—are effectively myths that lack Level 1 or 2 evidence. The core tension is between a historical focus with these external triggers and the clinical reality […]
