The effect of exercise in patients with colorectal cancer surgery: A systematic review

Abstract

Background

Current reviews have primarily focused on the effect of exercise on colorectal cancer patient's functional abilities and cardiorespiratory performance. There is a need for more comprehensive studies to determine the effects of exercise on different components. We aimed to investigate recent pre-operative and post-operative exercise interventions conducted in patients undergoing or scheduled for colorectal cancer surgery.

Methods

The PRISMA guidelines were followed. PubMed, Web-of-Science (WoS) and Scopus databases were searched. The Physiotherapy Evidence Database (PEDro) tool provided the methodological quality and risk of bias for the included trials. The review findings are presented using the principles of narrative synthesis. The synthesis process encompasses steps such as “developing a preliminary synthesis, exploring relationships within and between studies, and assessing the robustness of the synthesis.”

Results

The combined use of aerobic and resistance exercises reduces hospital stay in the preoperative period, long-term exercise interventions significantly improve functional parameters, and progressive relaxation exercises performed during the preoperative and postoperative periods reduce anxiety.

Conclusions

Long-term and combined (relaxation, aerobic and resistance) rehabilitation in colorectal cancer surgery is essential to improve the physical and psychological parameters of patients. Further studies should focus on more comprehensive, long-term exercise programs and separately investigate the effects of each exercise type.
