Introduction: To determine the rate of deteriorating activities of daily living (ADL) and to investigate predictive factors in elderly patients undergoing surgery for NSCLC. Methods: Patients with NSCLC aged 75 years or older who underwent curative surgical resection were evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence Instrumental ADL (TMIG-IADL) and the Japanese version of EuroQol 5-dimensions 5-level (EQ-5D-5L) quality-of-life scale administered at baseline and at 6 months postoperative. The primary end point was the rate of living patients without substantial deterioration of TMIG-IADL, defined as a decline greater than or equal to three points. Multivariable logistic regression was performed to determine risk factors for deteriorating ADL. Results: Between May 2019 and May 2020, 876 of the 986 screened patients enrolled from 47 institutions were eligible and included in the analysis. TMIG-IADL and EQ-5D-5L scores were obtained from 96.0% and 92.6% of the patients, respectively. At 6 months postoperative, 745 patients (85.1%, 95% confidence interval: 82.5%–87.3%) reported no significant ADL deterioration, and 96 of 841 patients (11.4%) with postoperative score data reported significant deterioration. The social domain was the most frequently affected activity. In multivariable analysis, poor performance status, low G8 geriatric screening score, segmentectomy (versus wedge resection), and surgery lasting less than 3 hours were associated with deteriorating ADL. Worsening EQ-5D-5L scores by minimally important difference or more were observed in 22.1% of the patients. Changes in TMIG-IADL and EQ-5D-5L scores were poorly correlated. Conclusions: Approximately 15% of elderly patients with NSCLC experienced significant ADL deterioration at 6 months postoperative.
