Abstract

Objective: This study aimed to evaluate and rank the effectiveness of pharmacological and non-pharmacological interventions for managing dyspnea severity, anxiety, exercise capacity, and health-related quality of life (HRQoL) in patients with advanced cancer.

Methods: A comprehensive search of PUBMED, HINARI, CENTRAL, and ResearchGate was conducted to identify randomized controlled trials (RCTs) published up to March 2024. Network meta-analysis was performed to compare interventions, calculating mean differences (MD) and standardized mean differences (SMD) with 95% confidence intervals (CI). P-scores were used to rank the interventions. Risk of bias was assessed using the Cochrane tool, and the quality of evidence (QOE) was evaluated using the GRADE framework.

Results: A total of 42 RCTs, encompassing 3,832 patients, were included in the analysis. Among the evaluated interventions, high-flow nasal cannula (HFNC) demonstrated the most significant improvement in dyspnea relief (SMD = -1.91; 95% CI: -3.32 to -0.49; QOE: moderate), followed by acupressure/reflexology (SMD = -1.04; 95% CI: -2.02 to -0.06; QOE: very low). Activity rehabilitation was the only intervention that significantly reduced anxiety compared to the control group (SMD = -0.64; 95% CI: -0.97 to -0.32; QOE: very low). While all interventions showed trends of improving exercise capacity, none reached statistical significance. Notably, acupressure/reflexology significantly enhanced HRQoL (SMD = 1.55; 95% CI: 0.22 to 2.88; QOE: moderate).

Conclusions: Non-pharmacological interventions, particularly HFNC and acupressure/reflexology, were more effective than pharmacological approaches in improving dyspnea relief and HRQoL. However, the low quality of evidence underscores the need for high-quality, large-scale trials to confirm these findings and refine treatment strategies for dyspnea management in advanced cancer patients.
