Interim analysis of the efficiency and safety of neoadjuvant PD-1 inhibitor (sintilimab) combined with chemotherapy (nab-paclitaxel and carboplatin) in potentially resectable stage IIIA/IIIB non-small cell lung cancer: a single-arm, phase 2 trial.

The current study found similar ORR, slightly lower MPR and pCR rates, and lower grade 3 TRAEs among patients with potentially resectable stage IIIA/IIIB NSCLC compared to the NADIM trial, as well as a greater ORR, MPR rate, pCR rate, and grade 3 TRAEs compared to Gao's study involving sintilimab for Chinese patients with resectable stage IA-IIIB NSCLC. Though neoadjuvant chemoimmunotherapy had been found to promote a high risk of BPF for patients with stage IIIA/IIIB disease, it offered greater potential for radical cure. Therefore, the current study suggests that neoadjuvant chemoimmunotherapy can be a safe approach in increasing the efficiency of treatment and hopefully improving the prognosis of patients with potentially resectable locally advanced NSCLC.
