The Impact of Tumor Cell Differentiation on Survival of Patients with Resectable Esophageal Squamous Cell Carcinomas

摘要

Background. The current American Joint Committee on Cancer staging system considers tumor cell differentiation grade to be a factor in the staging of esophageal squamous cell carcinoma (ESCC) in pathologic T0-3N0M0 cases. However, more data are essential to test its efficacy. We sought to investigate the tumor-node-metastasis categories for which tumor cell grade might affect overall survival in Chinese patients.
