A Study of Adebrelimab Combined With Apatinib Mesylate and Chemotherapy for Neoadjuvant Therapy and Biomarker Analysis in Limited-stage Small Cell Lung Cancer

Summary

This is a single-arm, prospective, exploratory phase II clinical study. The study enrolled newly diagnosed stage T1-3N0-1M0 resectable limited-stage small cell lung cancer. Adebrelimab combined with chemotherapy for 4 cycles and apatinib mesylate for 3 cycles. Surgery was performed within 4-8 weeks after the above treatment (the operation was performed 4 weeks after apatinib was discontinued). According to the results of MDT discussion, adebrelimab combined with apatinib mesylate combined with or without radiotherapy was started 4 weeks after surgery. Preoperative prophylactic radiotherapy (PCI) is recommended for patients with preoperative stage N1. Patients with postoperative stage N1 received postoperative thoracic radiotherapy.
