Physical activity guidelines in oncology: A systematic review of the current recommendations

This review aims to summarize the recommendations endorsed by scientific societies regarding physical activity for patients with cancer. A systematic search was conducted to identify guidelines endorsed by scientific societies and published in the last 15 years dedicated to physical activity for cancer patients. The AGREE II instrument was used to assess the methodological quality of the guidelines. Results are presented as qualitative synthesis. A total of 11 guidelines met the inclusion criteria. Seven were considered high quality, scoring ≥60 % in the AGREE II tool. All the guidelines recommended to include aerobic and resistance training as types of activities. Regarding the physical activity dosage, most suggested a generic 150 minutes/week of moderate-intensity activity plus resistance training twice a week. Three guidelines reported instructions for exercise prescription, including frequency, intensity, and duration of training sessions. Six guidelines reported exercise testing/medical clearance instructions, 9 provided considerations regarding adaptation/precautions, and 7 detailed the specialists for referral. Four guidelines considered motivational aspects related to physical activity and cancer. Although important steps have been made in the more recent recommendations, effort is needed to produce high-quality research in the exercise-oncology field, with the ultimate aim of developing more tailored guidelines.
