Clinical Trial: Development and Multicenter Validation of a Novel Bio-Anatomical Staging System for Predicting Survival and Tailoring Adjuvant Therapy in ESCC After Neoadjuvant Chemoimmunotherapy.

U.S., March 24 -- ClinicalTrials.gov registry received information related to the study (NCT07488624) titled 'Development and Multicenter Validation of a Novel Bio-Anatomical Staging System for Predicting Survival and Tailoring Adjuvant Therapy in ESCC After Neoadjuvant Chemoimmunotherapy.' on March 09.

Brief 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...
