Putting Exercise Into Oncology Practice: State-of-the-Science, Innovation, and Future Directions.

Physical activity provides numerous health benefits for cancer survivors. This review provides a summary of the evidence supporting the efficacy of physical activity to improve patient-reported and physiological outcomes during and after cancer therapy, discusses observational studies that have reported associations of physical activity with cancer outcomes and prognosis, summarizes ongoing phase III randomized trials of physical activity with clinical disease endpoints in cancer survivors, describes randomized trials of physical activity that have examined biomarkers hypothesized to relate to cancer outcomes and prognosis, reviews current guidelines for physical activity promotion among cancer survivors, and provides recommendations for novel strategies to disseminate and implement this evidence into clinical oncology practice to optimize patient outcomes.
