Effects of preoperative combined aerobic and resistance exercise training in cancer patients undergoing tumour resection surgery: A systematic review of randomised trials

However, our conclusions are limited by the heterogeneity of the preoperative CT programs, patient characteristics and measurement tools. Future research is required to determine the optimal composition of CT.
