Comparing Efficacies of Different Exercises on Androgen Deprivation Therapy Adverse Effects in Prostate Cancer Patients: A Network Meta-Analysis

Abstract

Introduction: Previous studies showed exercise have efficacies for androgen deprivation therapy (ADT) adverse effects. To compare the efficacies of different exercises on ADT adverse effects, we conducted the network meta-analysis (NMA).

Methods: Literature retrieval was performed in PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). Nineteen studies (1,184 participants) were included. All analyses were performed in R 4.1.2 or RevMan 5.4.1.

Results: NMA results showed that compared with the control group, both aerobic + resistance training (ART) (MD = 5.92, 95% CI: 0.38; 11.46) and resistance exercise (RE) (MD = 5.62, 95% CI: 2.70; 8.55) improved quality of life (QoL). ART (P score: 0.72) may have superiority over RE (P score: 0.7). ART (MD = -10.89, 95% CI: -17.67; -4.11) significantly improved the performance of 400-m test. RE could significantly improve leg strength (MD = 118, 95% CI: 78.75; 157.25) and chest strength (MD = 13.30, 95% CI: 4.07; 22.53). RE ranked first for strength improvements of leg and chest.

Conclusion: ART showed better efficacy for the QoL and significantly improved the performance of 400-m test. RE might be superior for the strengths of leg and chest. ART may be appropriate for patients with less significant muscle strength decline but also other adverse effects of ADT, such as decreased cardiopulmonary function.
