About

To compare the efficiency between surgery and radiotherapy after SHR-1316 (Adebrelimab)and platinum-containing doublet induction therapy for limited-stage small cell lung cancer

Full description

1.1 Main purpose To compare the efficiency between surgery and radiotherapy after therapy with SHR-1316 and chemotherapy for limited-stage small cell lung cancer according to progression-free survival (PFS) 1.2 Secondary Purpose The incidence of adverse events (AEs) during treatment was assessed to identify the safety of SHR-1316 and chemotherapy combined with surgery or radiotherapy according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0. To evaluate the pathological response rate (MPR and PCR) of the surgical population after neoadjuvant therapy with SHR-1316 and chemotherapy for operable LD-SCLC according to the evaluation criteria of pathological response after neoadjuvant therapy recommended by the International Association for the Study of Lung Cancer (IASLC); To evaluate the overall survival (OS) of patients with limited-stage small cell lung cancer after therapy with SHR-1316 and chemotherapy combined with surgery or radiotherapy To evaluate the recurrence-free survival (RFS) in patients with limited-stage small cell lung cancer who received neoadjuvant SHR-1316 and chemotherapy combined with surgery; To evaluate the duration of response (DOR) in patients with limited-stage small cell lung cancer after SHR-1316 and chemotherapy combined with surgery or radiotherapy according to RECIST v1.1 To identify the impact on the health-related quality of life (HRQoL), mood, symptoms, sleep, etc. of patients undergoing surgery and radiotherapy after therapy with SHR-1316 and chemotherapy according to the Pulmonary Hospital Psychological Assessment Scale; 1.3 Exploratory Purpose To explore potential predictive biomarkers in archived and/or fresh tumor tissue and/or blood (or blood derivatives), including but not limited to programmed cell death protein ligand 1 (PD-L1) expression as determined by immunohistochemistry (IHC), gene expression profile (GEP), tumor mutational burden (TMB), tumor-infiltrating immune cell changes, etc., to evaluate the association of these markers with the study of treatment response or resistance mechanisms.
