- Abstract
Objective: Whether to continue administering immunotherapy to patients with advanced non-small cell lung cancer (NSCLC) who have experienced tumor progression remains controversial after immunotherapy. The aims were to explore survival outcomes after further immunotherapy post-progression and to determine the optimal combination therapy in such cases., Methods: Overall, 507 patients with NSCLC who underwent immunotherapy and experienced tumor progression were retrospectively divided into Immuno-combination and No-immuno groups according to whether additional combination therapy involving immunotherapy was administered post-progression. Progression-free survival (PFS) and overall survival (OS) were evaluated. Subgroup analyses were performed according to the different treatment regimens for patients in the Immuno-combination group., Results: After propensity score matching, there were 150 patients in the No-immuno group and 300 patients in the Immuno combination group. Superior PFS was observed in the Immuno-combination group compared with those in the No-immuno group (6-month PFS: 25.3 % vs. 60.6 %; 12-month PFS: 6.7 % vs. 24.4 %; P < 0.001). Similar intergroup differences were observed for OS (12-month OS: 22.3 % vs. 69.4 %; 18-month OS: 6.4 % vs. 40.4 %; P < 0.001). Superior PFS outcomes were observed in the Immuno+Antiangiogenic group compared with the Immuno+Chemo group (6-month PFS: 51.3 % vs. 71.5 %; 12-month PFS: 23.1 % vs. 25.7 %; P = 0.017). Similar differences in OS were observed between those same subgroups (12-month OS: 62.1 % vs. 77.9 %; 18-month OS: 33.3 % vs. 48.7 %; P = 0.006)., Conclusion: Patients with NSCLC experiencing tumor progression post-immunotherapy can still benefit from further treatment, with immunotherapy combined with antiangiogenic therapy the most efficacious option., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.
