Administering perioperative immunotherapy both before and after surgery significantly improves event-free survival (EFS) in patients with resectable early-stage non-small cell lung cancer (NSCLC), according to a study presented at the European Society for Medical Oncology Congress 2023.
The CheckMate 77T trial was a randomized, double-blind study comprising more than 450 patients with NSCLC. The study subjects were randomized to treatment with either neoadjuvant nivolumab with chemotherapy followed by surgery and adjuvant nivolumab, or neoadjuvant chemotherapy and placebo followed by surgery and adjuvant placebo.
According to the results, the median EFS with chemotherapy alone was 18.4 months, while the median had not yet been reached for patients receiving perioperative nivolumab, meaning EFS was prolonged significantly compared with the control group. The researchers noted that these results correspond to a 42% reduction in risk of disease progression, recurrence, or death for those receiving the perioperative combination.
