Neoadjuvant immunotherapy combined with chemotherapy in the treatment of stage III lung squamous cell carcinoma: a retrospective cohort study
JOURNAL OF THORACIC DISEASE(2023)
Abstract
Background: Neoadjuvant immunochemotherapy has been proven to be a successful therapeutic strategy for patients with locally advanced non-small cell lung cancer (NSCLC). Nevertheless, there is a paucity of information regarding surgical feasibility and safety as well as tumor response. The present study aimed to investigate the therapeutic and surgical outcomes for patients with stage III lung squamous cell carcinoma (LSCC). Methods: Patients with stage III potentially resectable LSCC treated with neoadjuvant immunochemotherapy at The First Affiliated Hospital of Ningbo University between March 2020 and June 2022 were retrospectively included. Oncologic outcomes and intraoperative and postoperative variables were assessed. Results: A total of 17 locally advanced LSCC patients were included in the study. Patients in stages IIIA and IIIB were represented by 10 (58.8%) and 7 (41.2%) cases, respectively. A minimally invasive procedure was successfully completed in 12 out of 17 cases (70.6%). A total of 10 patients (58.8%) had standard lobectomies performed, 1 (5.9%) had a bilobectomy, 3 (17.6%) had pneumonectomies, and 1 (5.9%) had a wedge resection. A total of 7 patients (41.2%) experienced postoperative complications, and there were no 30-or 90-day mortalities. The 2-year disease-free survival (DFS) and overall survival (OS) rates were 76.6% and 82.5%, respectively. The rate of major pathological response (MPR) was 70.6%. Conclusions: Lung resection after immunochemotherapy for potentially resectable stage III LSCC is feasible and safe. This treatment strategy results in a significant pathologic response and promising rates of OS at 2 years.
