Abstract

Rationale: Quality of life (QoL) is an important issue in lung cancer survivors. We aimed to identify determinants of QoL in lung cancer survivors eligible for long-term cure. Methods: We performed an exploratory analysis of a cross-sectional study of consecutive lung cancer survivors who completed curative-intent treatment ≥1 month previously. Variables tested included demographic, clinical, physiologic, and symptom-specific patient-reported outcome measures. We defined the primary outcome as a previously-validated cancer-specific QoL measure - the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 (C30) summary score. We also verified our findings with the C30 global health status/QoL subscale and a summated score of lung cancer-specific QoL from the EORTC-Lung Cancer Module 13. Results: In 75 enrolled participants, measures of fatigue, depression, sleep difficulties, and dyspnea were statistically significant determinants of the C30 summary score in multivariable linear regression analyses. Together, these four symptoms accounted for approximately 85% of the variance in cancer-specific QoL (p<0.001). When we verified our findings with global QoL and lung cancer-specific QoL, fatigue and dysp...Continue Reading
