Abstract:
Objective:To explore the safety and therapeutic effect of programmed death 1 (PD-1) antibody combined with chemotherapy as a neoadjuvant therapy for patients with stage Ⅱ to Ⅲ non-small cell lung cancer (NSCLC).Methods:Thirteen patients, who had been diagnosed as stage Ⅱ-Ⅲ NSCLC and received PD-1 inhibitor plus chemotherapy as a neoadjuvant treatment in National Cancer Center/Cancer Hospital were recruited. The patients received consecutive neoadjuvant chemotherapy for 21 days as a cycle and the therapeutic efficacy was evaluated after two cycles.Results:At the last time of follow-up on December 2, 2019, the objective response rate (ORR) and disease control rate (DCR) of these patients were 61.5% (95% CI 30.9%-92.1%) and 100%, respectively. The downregulation rate of disease stage was 61.5% (8/13). The resectable rate was 38.5% (5/13), among them, the major pathologic response (MPR) was 60.0% (3/5) and the complete pathologic response (CPR) was 20.0% (1/5). The neoadjuvant chemotherapy displayed a low incidence of adverse reaction. The main grade 3 to 4 toxicities were neutropenia (38.5%) and leukopenia (23.1%). There was no significant immune-related toxicity. The safety and tolerability of perioperative period of patients underwent resection were promising. Conclusions:Immunotherapy combined with chemotherapy as a neoadjuvant treatment is an effective, low-toxicity treatment manner, which has perioperative safety and high rate of MPR for patients with resectable NSCLC. It is a promising treatment option for patients with stage Ⅱ to Ⅲ NSCLC.
