Exercise Training in Patients With Non-Small Cell Lung Cancer During In-Hospital Chemotherapy Treatment: A RANDOMIZED CONTROLLED TRIAL.

PURPOSE

The aim of this study was to perform a randomized trial to assess the impact of exercise training in patients with non-small cell lung cancer during chemotherapy on several outcomes in comparison to a control group (CG).

METHODS

The exercise training group (ETG) consisted of 20 patients and the CG consisted of 10 patients. In the ETG, a 4-wk in-hospital exercise training program was performed in 2-wk cycles interspersed with consecutive rounds of chemotherapy with cytostatic drugs. The exercise training program was individualized and included warm-up, respiratory muscle exercise, training on a cycle ergometer or treadmill, and Nordic walking. CG participants were assessed before and after 6 wk of chemotherapy alone.

RESULTS

Comparing pre- and post-intervention values, the ETG demonstrated an increase in 6-min walk distance (486 ± 92 vs 531 ± 103 m, P = .01). In a battery of physical performance tests: Up and Go Test (6.3 ± 1.0 vs 6.0 ± 1.1 sec, P = .01); chair stand (13.3 ± 2.8 vs 14.3 ± 3.4 repetitions, P = .001); and arm curl (18.4 ± 3.1 vs 20.4 ± 3.5 repetitions, P = .001) all improved significantly. Spirometry values also improved: FEV1 % predicted (76 ± 16 vs 84 ± 15, P = .01), FVC % predicted (87 ± 14 vs 95 ± 13, P = .01), and FEV1/FVC (73 ± 13% vs 76 ± 12%, P = .04). The exercise training was well tolerated, without any adverse events due to exercise. There were no significant improvements in the CG.

CONCLUSIONS

This study suggests that planned, individualized, and supervised exercise programs in patients with advanced lung cancer during chemotherapy are a practical and beneficial intervention for enhancing mobility and physical fitness.
