Abstract
BACKGROUND: Individuals with lung cancer (LC) face a variety of symptoms that significantly impact their lives. We use extensive patient input to determine the relative importance and prevalence of these symptoms and identify which demographic features are associated with a higher level of disease burden. METHODS: We performed semi-structured qualitative interviews with participants with LC to identify potentially important symptoms. We then conducted a cross-sectional study, in which participants rated the relative importance of 162 individual symptoms covering 14 symptomatic themes. Participant responses were analyzed by age, sex, disability status, disease duration, LC stage, type of treatment received, and smoking history, among other categories. RESULTS: Our cross-sectional study had 139 participants with LC. The most prevalent symptomatic themes reported by this population were fatigue (85.5%), impaired sleep and daytime sleepiness (73.5%), and emotional issues (73.0%). The symptomatic themes that had the greatest average impact (on a scale of 0 to 4, with 4 being the most impactful) were social role dissatisfaction (1.67), inability to do activities (1.64), and fatigue (1.60). Disability status had the strongest association with symptomatic theme prevalence. LC stage (stage IV), receipt of therapy, and smoking experience were also associated with higher frequency of symptomatic themes. CONCLUSIONS: Individuals with LC face diverse and disease-specific symptoms that affect their daily lives. Patient insight on the prevalence and relative importance of these symptoms is invaluable to advance meaningful therapeutic interventions.
