Introduction: This study aimed to estimate the utility values of all subtypes of lung cancer. The trajectories after different kinds of treatments and their major determinants were explored on the basis of real-world data and repeated measurements. Methods: From 2011 to 2017, all patients with lung cancer who visited a medical center were invited to fill out the EuroQol Five-Dimension and WHO Quality of Life-Brief questionnaires at each visit. Utility values of quality of life (QoL) after diagnosis and treatments were depicted using a kernel smoothing method. We constructed linear mixed models to predict health utility in each time period and cross-validated them with domain scores of the WHO Quality of Life-Brief. Results: A total of 1715 patients were enrolled, with 6762 QoL measurements. Utility values were lower in patients with advanced-stage disease and older patients. Patients receiving second-line targeted therapy showed higher utility values at 0 to 3 months, 3 to 6 months, and 6 months and beyond (0.89, 0.90, and 0.88, respectively) than did those undergoing chemotherapy (0.81, 0.85, and 0.80, respectively). After using mixed models to control confounders, including poor performance status and disease progression, patients receiving second-line chemotherapy showed health utility similar to that at quasi-baseline, whereas utility values related to second-line targeted therapy were higher at 3 to 6 months and 6 months and beyond (β = 0.07, p = 0.010 and β = 0.07, p < 0.001, respectively). There was convergent validity between the utility values and scores of the physical and psychological domains. Conclusion: Targeted therapy provided treated patients with a higher health utility value than was provided to those treated with chemotherapy. Development of the longitudinal trajectory may help predict changes in QoL and improve the care of lung cancer survivors.
