The Effect of Pulmonary Rehabilitation on Pulmonary Function Tests, Exercise Capacity, and Quality of Life in Patients With Advanced-Stage Lung Cancer Receiving Chemotherapy

This randomised controlled trial investigated the effects of an 8-week physiotherapist-supervised pulmonary rehabilitation (PR) programme on pulmonary function tests (PFT), exercise capacity, and health-related quality of life (HRQoL) in patients with advanced-stage lung cancer (Stage IIIB/IV) receiving chemotherapy. Thirty patients were randomised to a PR group (n=15) or a home-programme control group (n=15). The PR group underwent twice-daily supervised sessions comprising postural drainage with breathing exercises, bronchial clearance techniques, active cycle of breathing technique (ACBT), effective coughing manoeuvres, and strengthening exercises - plus home aerobic walking 20 min/day. The control group performed home-based breathing and coughing exercises twice daily. Results: The PR group showed significant improvements in 6MWT (+85.8 m; p=0.001), FVC, FEV1, PEF (all p=0.001), and all 8 LCSS symptom domains (p=0.001). The control group showed significant declines in FEV1, PEF, 6MWT, and worsening quality of life. Between-group differences were significant for all primary outcomes (p≤0.001).
