Abstract excerpt
Immune checkpoint inhibitors have improved outcomes in small-cell lung cancer (SCLC), yet durable benefit remains limited, and the immune consequences of SCLC transformation from EGFR-mutant lung adenocarcinoma (LUAD) remain incompletely understood. Conventional explanations for resistance emphasize PD-L1 expression, tumor mutational burden, T-cell dysfunction, myeloid suppression, and stromal exclusion, but...
