The participants were requested to complete the following structured questionnaires: a sociodemographic and clinical questionnaire, the Functional Assessment of Cancer Therapy–Lung (FACT-L), the Self-Perceived Burden Scale (SPBS) and the COmprehensive Score for Financial Toxicity (COST). The data were subjected to Pearson correlation analysis and bootstrapping analysis in structural equation modelling.Results: The total FACT-L score was 79.90± 15.84 points in 322 lung cancer patients receiving immunotherapy. FT (β = 0.37, P < 0.01) and SPB (β = − 0.27, P < 0.01) had a direct effect on QOL. In addition, SPB partly mediated the association between FT and QOL, and the standardized indirect effect was 0.19, accounting for 33.9% of the total effect.Conclusion: The present study revealed that there is still much room for improvement in the QOL of lung cancer patients during immunotherapy. A greater financial burden resulted in a greater self-perceived burden and was thus associated with inferior QOL. It is imperative for oncology nurses to routinely assess QOL, FT or risk and SPB for lung cancer patients undergoing immunotherapy as well as to assist those patients in understanding the potential financial risk of each choice and help them take more active roles in their routine clinical care.Keywords: lung cancer, immunotherapy, quality of life, financial toxicity, self-perceived burden
