A recent analysis of two phase III trials revealed a significant reduction in the risk of non-small cell lung cancer (NSCLC) recurrence or death among post-surgical patients who received perioperative nivolumab in combination with chemotherapy. The study, conducted by Patrick Forde, MD, of Johns Hopkins Medicine, showed a 40% decrease in the risk of disease recurrence or death after surgery in patients who had received adjuvant nivolumab following neoadjuvant nivolumab plus chemotherapy and surgery. This comparison sheds light on the potential benefits of perioperative immunotherapy for individuals with resectable lung cancer.
Although the results of this analysis are promising, it is crucial to note that this is an exploratory study, and further validation through phase III randomized clinical trials is necessary. Nan Wu, MD, of Peking University Cancer Hospital in Beijing, emphasized the importance of additional research to confirm the efficacy of perioperative nivolumab as a treatment option for eligible patients with resectable NSCLC.
The comparison of event-free survival (EFS) between patients in the CheckMate 77T and CheckMate 816 trials highlighted the benefits of neoadjuvant nivolumab plus chemotherapy in improving EFS. Patients in CheckMate 816 who received the nivolumab/chemotherapy combination demonstrated a significant increase in median EFS compared to those who received chemotherapy alone. This regimen has been specifically approved by the FDA for resectable NSCLC, underscoring its importance in the field of oncology.
Forde and colleagues conducted propensity score weighting analyses to adjust for baseline demographics and disease characteristics between the two study populations. The results showed a substantial EFS benefit with perioperative nivolumab compared to neoadjuvant-only therapy. This benefit was observed across different stages of the disease, regardless of the clinical stage or pathological complete response (pCR) status. Furthermore, patients with PD-L1-negative tumors also experienced a significant EFS benefit with perioperative nivolumab, highlighting its potential in treating a broad spectrum of patients.
One of the key findings from the analysis was the comparable safety profiles of perioperative and neoadjuvant nivolumab. Both treatment approaches showed similar rates of treatment discontinuation and surgery-related adverse events, indicating that perioperative nivolumab is a viable option for patients undergoing surgical treatment for NSCLC.
The analysis of perioperative nivolumab in combination with chemotherapy has shown promising results in reducing the risk of NSCLC recurrence or death among post-surgical patients. However, further research is needed to validate these findings and establish perioperative nivolumab as a standard treatment option for individuals with resectable lung cancer.
