Background: Rechallenge with immune checkpoint inhibitors (ICI) shows promise in various cancers, but data esophageal squamous cell carcinoma (ESCC) is limited.This study aimed to evaluate the efficiency and safety of ICI rechallenge ESCC.Materials Methods: This multicenter analyzed ESCC patients rechallenged from January 2020 March 2023 across two medical institutions.Patients were divided into (R) non-rechallenge (NR) groups.Key outcomes studied progression-free survival (PFS), overall (OS), safety.Results: Among 329 included patients, 211 R group 118 NR group, a median follow-up 17.1 months.The exhibited significantly prolonged PFS (4.7 vs. 3.2 months; p <.001) OS (9.3 6.2 compared group.Notably, for who initially received radiotherapy, showed longer mPFS (5.1 mOS (10.4 5.9 <.001).Incidences all-grade (64.5% 66.1%;p = .764)and grade ≥3 adverse events (17.5% 18.6%; .802)did not differ between groups.Conclusion: demonstrates efficacy manageable ESCC, particularly post-radiotherapy.

Manipulating the immune system by blocking checkpoint receptors is basis of immunotherapy, a relevant tool in current clinical oncology. The strategy checkpoints (Immune Checkpoint Inhibitors, ICI) consists using monoclonal antibodies to inhibit interaction between ligand and inhibitory from triggering complete activation helper cytotoxic T cells fight against tumour cells. Immunotherapy has benefited patients with diverse cancers such as stomach, lung, melanoma, head neck squamous cell carcinoma, among others. Unfortunately, growing number reports have indicated that ICI treatment also can show dark side under specific conditions; some adverse effects induced are immunosuppression, opportunistic infections, organ-specific alterations. This review discusses immunologic aspects related these unwanted effects.
