Survival after neoadjuvant chemotherapy or chemoradiotherapy for resectable esophageal squamous cell carcinoma: A pooled analysis of randomized clinical trials. Radiother Oncol 2024; 200:110517. [PMID: 39218039 DOI: 10.1016/j.radonc.2024.110517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 08/22/2024] [Accepted: 08/28/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND The comparison of neoadjuvant chemoradiotherapy (nCRT) versus neoadjuvant chemotherapy (nCT) for locally advanced esophageal squamous cell carcinoma (ESCC) remains inconclusive, and the optimal regimen is still under investigation. METHODS Prospective randomized clinical trials were systematically searched in electronic databases from inception to Oct 2023. A graphical reconstructive algorithm was employed to extract time-to-event outcomes from Kaplan-Meier curves presented in the original studies. Using reconstructed individual patient data, summary overall survival (OS) and disease progression-free survival (DFS) for nCRT versus nCT, primarily doublet chemotherapy were recalculated. Hazard Ratios (HRs) of OS and DFS reported were also pooled by the fixed-effects model. RESULTS A total of 6 randomized clinical trials comprising 1162 patients were included in our analysis. In the individual patient data (IPD) pooled analysis, a significant OS benefit was found for nCRT in ESCC (HR=0.81, 95 %CI:0.67-0.98, p=0.029), compared with the treatment of nCT. The median overall survival time were 53 months (95 %CI:41.9-67.7 m) and 66 months(95 %CI:57.2-NA) respectively in the nCT and nCRT groups. Additionally, a significant improvement in PFS for nCRT compared to nCT in the IPD pooled analysis (HR=0.79,95 %CI:0.64-0.98; p=0.027). Consistent with above results, the pooled HRs of OS and DFS for nCRT versus nCT were 0.78 (95 % CI 0.65-0.92, p=0.004) and 0.79 (95 % CI: 0.65-0.97, p=0.02), respectively. Notably, no substantial heterogeneity across studies was observed. CONCLUSIONS Our findings indicate that nCRT offers better survival outcomes for ESCC, at least when compared to neoadjuvant doublet chemotherapy.This evidence continues to support the clinical practice of employing nCRT in locally advanced resectable ESCC.

Abstract
Objective: This research aimed to assess the efficacy and safety of pembrolizumab (PBL) combined with albumin-bound paclitaxel (ab-Pac) and nedaplatin (NDP) for advanced esophageal squamous cell carcinoma (ESCC). Methods: A total of 47 ESCC patients were administered PBL or NDP on day 1 and ab-Pac on days 1 and 8, every 21 days for one cycle. Tumor and toxicities were evaluated every two cycles and every cycle, respectively. Results: The objective response rate was 68.1% and the disease control rate was 100%. The median follow-up was 16.7 months; median progression-free and overall survival were 12.6 and 19.9 months, respectively. Conclusion: The combination of PBL with ab-Pac and NDP proved to be an effective and safe treatment regimen for advanced ESCC.

Abstract
Oesophageal squamous cell carcinoma (ESCC) is a kind of malignant tumour with high invasiveness and a poor prognosis. Immunotherapy, especially immune checkpoint inhibitors (ICIs), is a rapidly growing therapeutic method that activates and enhances anti-tumour immunity to treat patients with malignancy. Several clinical trials have confirmed the efficacy of ICIs in the treatment of ESCC. ICIs have been approved for the treatment of patients with ESCC. However, only a subset of patients can obtain excellent benefits from ICI therapy. In recent years, there has been a growing interest in exploring predictive biomarkers of immunotherapy response. In this review, we highlighted the predictive biomarkers for the prognosis of ESCC patients treated with ICIs and pointed out the existing problems and the direction of future research in this field.
