What this Trial Is About

The aim of this clinical trial is to evaluate the efficacy and safety of consolidation therapy with a neoantigen-loaded dendritic cell vaccine (NeoDC-Vac) following radical chemoradiotherapy or chemoradiation-immunotherapy in patients with locally advanced, unresectable ESCC. The primary endpoint of the study is the OS rate. Secondary endpoints include OS, PFS, adverse events, CR rate, and quality of life (QoL) of patients. Exploratory endpoints involve the assessment of biomarkers such as TMB, PD-L1, and ctDNA. The key questions this study aims to answer are: -Can the combination of (ICIs and NeoDC-Vac as maintenance therapy improve OS and QoL in patients with locally advanced, unresectable ESCC following radical treatment? Can this novel approach provide an effective treatment option for these patients? Participant Procedures: 1. Endoscopic examination at West China Hospital. Baseline fresh tumor tissue collection for NGS in neoantigen vaccine group. 2. Screening assessments, informed consent, and random assignment to experimental or control group. Experimental Group\*\*: Neoantigen-loaded vaccine + standard ICIs as maintenance therapy. Control Group\*\*: Standard ICIs as maintenance. One cycle per month for one year. 3. Tumor tissue NGS, ctDNA analysis, TIME evaluation, T cell response profiling. All costs covered by research funding. 4. After completing the full treatment regimen, participants will be monitored with regular follow-up visits by healthcare professionals to assess ongoing health outcomes and safety.
