摘要

Background

While neoadjuvant chemotherapy (NCT) and neoadjuvant immunochemotherapy (NICT) are effective treatments for locally advanced esophageal squamous cell carcinoma (ESCC), comparative analyses of their long-term survival outcomes are scarce. This study aims to evaluate the treatment efficacy, safety, and survival outcomes between NICT and NCT.

Methods

This retrospective study included 157 patients with locally advanced ESCC who underwent NCT or NICT followed by surgery at our hospital. To minimize confounding factors, PSM at a 1:1 ratio was conducted.

Results

After PSM, a total of 51 matched pairs of ESCC patients receiving NICT and NCT were included for analysis. The median follow-up was 48.6 months (95% CI, 39.14–58.07). The NICT group showed significantly better overall survival (OS) and disease-free survival (DFS) than the NCT group (3-year OS: 78% vs 57%, P = 0.029; 3-year DFS: 68% vs 43%, P = 0.005). The NICT group achieved significantly higher partial response (PR) rates (78.4% vs 56.9%, P = 0.019) and pathological complete response (pCR) rates (27.5% vs 5.9%, P = 0.013) compared to the NCT group. No significant difference was observed in the overall incidence of treatment-related adverse events and postoperative complications between the two groups. Patients who achieved tumor remission, downstaging, or pCR experienced significantly longer OS and DFS (P < 0.05).

Conclusion

For ESCC, NICT may offer a more sensitive treatment response and higher pathological remission rates than NCT, without increasing the risk of treatment-related adverse events or postoperative complications, indicating superior safety, efficacy, and long-term survival advantages.
