Neoadjuvant chemoradiotherapy (nCRT) is the current standard of care, while neoadjuvant immunochemotherapy (nICT) has emerged as a promising alternative. However, no large-scale randomized controlled trial has directly compared nICT versus nCRT for long-term overall survival (OS) in this population. This study aims to compare the causal effects of nICT versus nCRT on OS and other key outcomes in patients with resectable locally advanced ESCC using target trial emulation (TTE) methodology. This is a single-center, retrospective, observational cohort study using TTE. Data are derived from electronic health records (EHR) of esophageal cancer patients hospitalized at Henan Cancer Hospital between January 2013 and December 2025. Patients meeting eligibility criteria (age ≥18 years; histologically confirmed ESCC; clinical stage cT3-4a N0-2 M0 or cT2N+ M0; ECOG PS 0-1; no prior antitumor therapy) are assigned to nICT or nCRT groups based on actual treatment initiation. Propensity score overlap weighting is used to balance baseline covariates. The primary outcome is overall survival (OS). Secondary outcomes include event-free survival (EFS), pathological complete response (pCR) rate, tumor regression grade (TRG), R0 resection rate, and safety. This study will provide real-world causal evidence on the comparative effectiveness of nICT versus nCRT in the Chinese ESCC population.",[63],"Esophageal Squamous Cell Carcinoma (ESCC)",[65,66,67,68,69,70],"Esophageal Cancer","Squamous Cell Carcinoma","Neoadjuvant Immunochemotherapy","Neoadjuvant Chemoradiotherapy","Target Trial Emulation","Real-World Data","NOT_YET_RECRUITING","2026-08-17",{"date":74,"type":75},"2026-08-21","ACTUAL",{"date":77,"type":59},"2026-08-20",{"date":79,"type":59},"2028-08-20",{"name":5,"class":6}]
