Abstract Background This study aimed to evaluate if neoadjuvant immune checkpoint inhibitor (ICI) plus chemotherapy (CT) reduced tumor recurrence after surgery than neoadjuvant CT alone in non–small cell lung cancer (NSCLC) patients with pathologic complete response (pCR). Methods From January 1st 2019 to April 30th 2022, 16 NSCLC patients with pCR who received both neoadjuvant ICI and CT were designated as ICI/CT group. Another 8 patients, who received neoadjuvant CT alone, were designated as CT group. The tumor recurrence and patients’ survival status were analyzed. Results Squamous cell carcinoma was the predominant histology type in both groups. The CT group had higher percentage of patients who received adjuvant CT than the ICI/CT group (100% vs. 75%, p = 0.046). All patients had been followed up for at least 20 months. At 20 months after surgery, the ICI/CT group had a tumor recurrence rate of 6.25%, which was significantly lower than 37.5% recurrence rate of the CT group. One patient of the CT group died of gastrointestinal hemorrhage and severe anemia at 11 months after surgery, and no patient in the ICI/CT group died. During adjuvant therapy, the ICI/CT group had significantly lower risk of anemia (12.5% vs. 50%) than the CT group (p = 0.046). Conclusion The study found that in NSCLC patients with pCR, neoadjuvant ICI reduced tumor recurrence rate. This indicated that like in advanced stage NSCLC, the ICI might bring similar long-term anti-tumor effect in operable NSCLC patients. |
