Summary

The goal of this retrospective observational study is to build and validate a "bio-anatomical" prognostic model for patients with esophageal squamous cell carcinoma (ESCC) who underwent neoadjuvant immunochemotherapy (nICT) followed by radical surgery. The main question it aims to answer is:

Can a "bio-anatomical" prognostic nomogram accurately predict overall survival and help guide individualized post-surgery treatment for ESCC patients after nICT better than traditional staging? Researchers will retrospectively analyze the clinical, pathological (including a new lymph node response indicator), and overall survival data of 414 eligible patients treated across three medical centers between 2019 and 2025.
