Interpretation of update on The AJCC Esophageal Cancer Staging System, Eighth Edition / 中华外科杂志

ABSTRACT

The recently published AJCC Esophageal Cancer Staging System, 8th Edition will be implemented on Januray 1, 2018, which was developed by Worldwide Esophageal Cancer Collaboration based on 22 654 esophageal cancer patients from 33 worldwide centers. The definition of T, N, M, G stage and regional lymph nodes were optimized in the 8th edition. And the new "2 cm" principle has simplified the definition for the cancer of esophagogastric junction. In addition to pathologic staging, the 8th edition also provided clinical staging and pathologic staging after neoadjuvant therapy, making the new esophageal cancer staging system more practicable and reasonable.
