Abstract
Purpose
To assess the effectiveness of healthy lifestyle–based interventions in lung cancer survivors.
Methods
We performed a literature search using PubMed, Web of Science, and Science Direct (last search March 2022). Quality assessment and risk of bias were assessed using the Downs and Black scale and the Cochrane tool. A systematic review and meta-analysis of randomized controlled trials were performed. We included controlled trials testing the effect of healthy lifestyle–based interventions in lung cancer survivors versus a control intervention where lung cancer patients had no treatment, were receiving the usual care, or had not an active role in the intervention. The data were pooled and a meta-analysis was completed for quality of life, psychological distress, and cancer-related symptoms.
Results
We selected 14 studies, which included 1519 patients with lung cancer. The treatment status of these patients was heterogeneous. Healthy lifestyle programs were applied isolated or in combination with usual care in most of the studies. The components of the healthy lifestyle programs were also heterogeneous. Results showed significant differences in favor of healthy lifestyle–based interventions in comparison to the control group for quality of life (p = 0.01), psychological distress (p = 0.05), and cancer-related symptoms (p = 0.03).
Conclusions
The findings indicated a beneficial effect of healthy lifestyle–based interventions for improving quality of life, psychological distress, and cancer-related symptoms in lung cancer patients. However, this review could not show any conclusion about the better treatment moment to apply healthy lifestyle–based interventions.
