The Effect of Exercise on Quality of Life in Patients With Advanced Lung Cancer: A Secondary Analysis of a Randomized Controlled Trial
Abstract
BACKGROUND
Chemotherapy is the primary treatment for lung cancer; however, it often leads to adverse side effects such as nausea, fatigue, and neuropathy, potentially compromising treatment adherence and patient quality of life. Exercise has emerged as a promising therapy, with evidence suggesting that physical activity during chemotherapy can mitigate symptoms and enhance overall well-being. This exploratory analysis investigates the efficacy of a 12-week exercise intervention on health-related quality of life (HRQoL) in patients with advanced lung cancer undergoing chemotherapy.
METHODS
218 participants with advanced lung cancer were randomized to either a 12-week exercise intervention or usual care. HRQoL was assessed at baseline and after 12 weeks using the European Organization for Research and Treatment of Cancer (EORTC) core Quality of Life Questionnaire (QLQ-C30) and the EORTC lung cancer-specific Quality of Life Questionnaire (QLQ-LC13).
RESULTS
Peripheral neuropathy remained unchanged in the intervention group (95% CI, -8.5-3.3, P = .39), but increased with 6.2 (95% CI, 1.3-11.1, P = .02) in the control group, resulting in a between group difference of -8.8 (95% CI, -16.4 to -1.1, P = .03). Moreover, the intervention group demonstrated a decrease in pain other of -7.4 (95% CI, -14.1 to -0.8, P = .03), where the control group remained unchanged (95% CI, -4.5-11.3 P = .40), resulting in a between group difference of -10.8 (95% CI, -21.1 to -0.6, P = .04).
CONCLUSION…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 218 participants or records.
