Nondrug Therapies Ease Cough in Lung Cancer, Pulmonary Rehab Leads Pack

Cough afflicts a majority of people living with lung cancer, yet it remains one of the most undertreated symptoms of the disease. A new meta-analysis suggests the fix does not always require a prescription.¹

A Symptom That Resists Easy Treatment

Cough is a prevalent and often debilitating symptom of lung cancer that remains poorly managed by conventional pharmacologic approaches, which frequently fall short or carry burdensome adverse effects such as sedation or constipation from opioid-based antitussives. A 2010 UK clinical guideline on cough in lung cancer called for a stepped approach moving from peripherally acting treatments to centrally acting options, such as opioids, but acknowledged that high-quality evidence remained scarce even for that pharmacologic ladder.²

Against that backdrop, researchers conducted a systematic review and meta-analysis to evaluate the growing body of evidence on nonpharmacological interventions for managing cough specifically among patients with lung cancer.¹

The review searched 9 databases from inception through December 2024 to identify randomized controlled trials, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and registered prospectively with PROSPERO (CRD42024588729). Study quality was appraised using the revised Cochrane Risk-of-Bias Tool for Randomized Trials, and meta-regression and subgroup analyses were used to explore sources of heterogeneity across trials.

In total, 38 studies representing 2995 patients with lung cancer were identified, evaluating interventions that included acupuncture, moxibustion, pulmonary rehabilitation, self-management programs, physical exercise, psychoeducation support, mindfulness, and multicomponent approaches.

Pulmonary Rehabilitation Stood Out

Nonpharmacological interventions overall showed positive effects on both cough severity and cough-related quality of life (QOL). Additional benefits emerged for expectoration, dyspnea, and general QOL across the pooled trials. Among the individual intervention types studied, pulmonary rehabilitation showed a greater effect on cough severity than the other approaches evaluated.

“Nonpharmacological interventions demonstrated potential effects in relieving cough and additional benefits in improving expectoration, dyspnea, and general quality of life among lung cancer patients,” the researchers wrote. Pulmonary rehabilitation, they noted, showed the most promising effect, and health care professionals may consider adopting it for cough and related symptoms in this population.

Reliance on Self-Reported Cough

Most trials included in the meta-analysis relied on patient-reported cough measures rather than objective cough-monitoring technology, which can introduce reporting bias and limits comparability across studies using different self-report instruments. Heterogeneity in intervention protocols, dosing, and duration across the 38 trials further complicates direct comparison between intervention types.

The authors called for future research to incorporate objective cough measures alongside self-reported outcomes to strengthen the evidence base going forward.

For oncology nurses and palliative care teams, the findings offer a lower-risk complement to pharmacologic cough management—one that, in the case of pulmonary rehabilitation, may also address the dyspnea and deconditioning that often accompany advanced lung cancer, with implications for how survivorship and symptom-management programs are structured and reimbursed.
