Lymph Node Regression Improves Prognostic Stratification in Esophageal Squamous Cell Carcinoma Receiving Neoadjuvant Chemoimmunotherapy: A Multicenter Retrospective Cohort Study
ABSTRACT Lymph nodes (LNs), principal sites of antitumor immunity, may undergo immune‐mediated regression; whether neoadjuvant chemoimmunotherapy (NCIT)‐induced regression indicates prognosis in esophageal squamous cell carcinoma (ESCC) remains unclear. We aimed to establish and validate a lymph node regression grade (...
