The recent analysis of two phase III trials exploring the use of perioperative nivolumab in non-small cell lung cancer (NSCLC) patients post-surgery has shown promising results. The study conducted by Patrick Forde, MD, and colleagues at Johns Hopkins Medicine in Baltimore demonstrated a significant reduction in the risk of disease recurrence or death among patients who received adjuvant nivolumab compared to those who did not. This analysis has sparked discussions about the potential benefits of perioperative immunotherapy in resectable lung cancer patients.
The comparison of patient-level data between the two trials, CheckMate 77T and CheckMate 816, supports the use of perioperative nivolumab as a treatment option for eligible patients with resectable NSCLC. CheckMate 816 showed improvements in event-free survival (EFS) with neoadjuvant nivolumab plus chemotherapy compared to chemotherapy alone. On the other hand, CheckMate 77T demonstrated clinically meaningful improvements in EFS with perioperative nivolumab, making it the sole FDA-approved neoadjuvant-only immunotherapy-containing regimen for resectable NSCLC.
To mimic the design of a randomized trial, Forde and colleagues performed 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 regardless of clinical stage, pathological complete response status, and PD-L1 expression. The safety profiles of perioperative and neoadjuvant nivolumab were found to be comparable, with similar rates of treatment discontinuation and surgery-related adverse events in both groups.
The findings from this analysis have significant implications for the treatment of resectable NSCLC patients. The potential benefits of perioperative nivolumab in reducing the risk of disease recurrence or death post-surgery are promising. However, further validation through phase III randomized clinical trials is necessary to establish the efficacy of this treatment approach. Clinicians may consider these results when making clinical decisions for patients who have undergone neoadjuvant therapy and surgery for resectable lung cancer.
The analysis of post-surgical treatment with nivolumab in NSCLC patients has provided valuable insights into the potential benefits of perioperative immunotherapy. The reduction in the risk of disease recurrence or death observed among patients who received adjuvant nivolumab highlights the importance of exploring novel treatment approaches in resectable lung cancer. While this analysis serves as an informative comparison of perioperative versus neoadjuvant-only immunotherapy treatments, further research is needed to confirm the efficacy of perioperative nivolumab in improving outcomes for NSCLC patients post-surgery.
