To investigate the efficacy and safety of programmed death protein 1 (PD-1) inhibitors in elderly patients with advanced non-small cell lung cancer (NSCLC) in a real-world setting.
The medical records of 103 patients with advanced NSCLC who received PD-1 inhibitors from January 1, 2020 to January 1, 2023 were retrospectively analyzed 103 patients with advanced NSCLC to compare the objective response rate (ORR), disease control rate (DCR), and adverse drug reaction (ADR) incidence rates among patients aged 65 to 74 years and those 75 years and older.
The ORR for the 65-74 age group (n=93) and ≥75 years group (n=10) was 44.09% and 40.00%, respectively. DCR was 83.87% and 90.00%, respectively. The overall incidence of ADR was 95.70% and 100.00%, and the incidence of grade ≥3 ADR was 18.28% and 20.00%. No statistically significant differences were observed between groups.
Elderly patients with advanced NSCLC receiving PD-1 inhibitors showed similar efficacy and safety between 65-74 years and ≥75 years. However, given the small sample size in the ≥75 years group, these preliminary results warrant further validation through large-scale, prospective studies.
