Effects of exercise training on patients with lung cancer who underwent lung resection: a meta-analysis

Abstract

Background

The efficacy of exercise training in patients with lung cancer after lung resection has not been well established yet. Therefore, we performed a meta-analysis to investigate the efficiency of exercise training in patients with lung cancer after lung resection.

Methods

Several databases were searched for eligible randomised controlled trials (RCTs). The primary outcome was quality of life, and the secondary outcomes included 6-min walk distance (6MWD), forced expiratory volume in 1 s (FEV1) and postoperative complications (POCs). Weighted mean differences (WMDs) and relative risks (RRs) with 95% confidence intervals (CIs) were calculated by random-effects model.

Results

Six RCTs involving 438 patients were enrolled in this meta-analysis. The pooled WMDs of the scores were 2.41 (95% CI = −5.20 to 10.02; P = 0.54) and −0.46 (95% CI = −20.52 to 19.61; P = 0.96) for the physical and mental components of the 36-item short-form scale, respectively. The pooled WMDs were 23.50 m (95% CI = −22.04 to 69.03; P = 0.31) for 6MWD and 0.03 L (95% CI = −0.19 to 0.26; P = 0.76) for FEV1. Finally, the pooled RRs were 0.79 (95% CI = 0.41 to 1.53; P = 0.49) for POCs.

Conclusions

Insufficient evidence is available to support the efficacy of exercise training in patients with lung cancer after lung resection. Further studies must confirm our findings and investigate the long-term effects of exercise training on patients with lung cancer following lung resection.
