Yoga for Treatment-related Complications in Patients with Breast Cancer: A Systematic Review of Randomized Control Trials

Abstract

Background: Despite the advancements in oncology, the prevalence of treatment-related complications remains high throughout the course of cancer treatment. Extensive research has indicated that yoga can have a positive influence on both physical and mental energy, potentially alleviating the severity of these complications. Objectives: The objective of this systematic review was to investigate the efficacy of yoga interventions in managing treatment-related complications among cancer patients Methods: A systematic search of electronic databases, including Medline, Science Direct, Cochrane Library, and Scopus, was conducted from 2000 to 2020. The search focused on randomized controlled trials that compared yoga interventions with other interventions for the management of cancer treatment-related complications. Female cancer patients participating in yoga interventions of any style and duration were included. The primary outcome measure of interest was the change in treatment-related complications from pre- to post-yoga intervention. Results: A total of 20 randomized controlled trials were identified, encompassing a sample size of 1349 cancer patients. These trials incorporated six different styles of yoga to manage treatment-related complications. The reviewed studies consistently demonstrated significant short-term improvements in anxiety, depression, emotional function, and fatigue levels. Furthermore, regular practice of yoga exhibited positive impacts on cognition, pain management, nausea, vomiting, swelling, and shoulder strength improvement. Conclusion: The findings from the included studies strongly suggest that yoga, in its various forms, durations, and interventions, is equally effective in managing cancer treatment-related complications. Consequently, the integration of yoga into cancer treatment protocols has the potential to enhance the overall quality of life for patients with cancer.
