Immune checkpoint inhibitor efficacy and safety in older non-small cell lung cancer patients.

Abstract：

OBJECTIVES:Immune checkpoint inhibitors offer longer survival than chemotherapy in several clinical trials for advanced non-small cell lung cancer. In subset analyses of clinical trials, immune checkpoint inhibitors extended survival in patients aged ≥65 years, but the effects in patients aged ≥75 years are controversial. We performed multicenter, collaborative and retrospective analyses of immune checkpoint inhibitor efficacy and safety in non-small cell lung cancer patients aged ≥75 years. METHODS:We retrospectively studied 434 advanced non-small cell lung cancer patients who received immune checkpoint inhibitors from December 2015 to December 2017, and retrospectively applied the Geriatric (G) 8 screening tool with medical records. RESULTS:Of the 434 patients who received immune checkpoint inhibitors, 100 were aged ≥75 years. Five patients with performance status 3 were omitted from the final analysis. Immune checkpoint inhibitors were given as a first-line treatment to 20 patients. The objective response rates, median progression-free survival rates and median survival times were 35.0%, 6.1 months and 10.7 months for first-line treatment, and 20.0%, 2.9 months and 14.7 months for second- or later-line treatments, respectively. The median modified G8 score was 11.0. The median survival time was longer in the high modified G8 (≥12.0) group than in the low modified G8 (≤11.0) group (18.7 vs. 8.7 months; P = 0.02). Likewise, the median survival time was 15.5 months (performance status 0-1) vs. 3.2 months (performance status 2) (P < 0.01). The grade ≥ 2 immune-related adverse events incidence was 36.8%. CONCLUSIONS:In this study, immune checkpoint inhibitors were effective and tolerable for patients aged ≥75 years. The modified G8 screening tool and performance status were associated with the outcome of older non-small cell lung cancer patients treated with immune checkpoint inhibitors.
