Neoadjuvant Immunochemotherapy vs Chemoradiotherapy in ESCC

Brief summary (registry, in English)

This retrospective real-world study aimed to compare neoadjuvant immunochemotherapy (NICT) and neoadjuvant chemoradiotherapy (NCRT) followed by esophagectomy in patients with locally advanced esophageal squamous cell carcinoma (ESCC). A total of 203 consecutive patients treated at Sichuan Cancer Hospital between March 2018 and March 2022 were analyzed (NICT: 59; NCRT: 144). The primary endpoints were overall survival (OS) and disease-free survival (DFS); secondary endpoints included pathological complete response (pCR), tumor regression grade (TRG), and R0 resection rate. After inverse probability of treatment weighting adjustment, baseline characteristics were balanced between groups. Both groups achieved comparable long-term OS and DFS, while NCRT showed higher rates of local pathological response. Exploratory subgroup analysis suggested that patients achieving pCR after NICT might have superior survival outcomes. The study indicates that NICT provides similar long-term survival compared to NCRT and may offer immunologic advantages for selected responders, warranting further validation in prospective multicenter trials.
