Adebrelimab plus chemotherapy and sequential thoracic radiotherapy as first-line therapy for extensive-stage small–cell lung cancer (ES-SCLC): a phase II trial

This phase II prospective trial aimed to investigate the efficacy and safety of adebrelimab (PD-L1 antibody) plus first-line chemotherapy followed by sequential thoracic radiotherapy (TRT) combined with adebrelimab in extensive-stage small-cell lung cancer (ES-SCLC). Biomarkers associated with potential therapeutic effects were also explored.
