Esophagus
Histologies Stage Table
- Note 1: The determination of AJCC stage group from T, N, M, and grade for Esophagus depends further on histologic type. This table shows the selection of the appropriate version of the AJCC Stage table based on histology. In the table below, "Squamous" maps to the table AJCC TNM 7 Stage Squamous and "Adenocarcinoma" maps to the table AJCC TNM 7 Stage Adenocarcinoma.
- Note 2: Effective with AJCC TNM 7th Edition, there are separate stage groupings for squamous cell carcinoma and adenocarcinoma. Since squamous cell carcinoma typically has a poorer prognosis than adenocarcinoma, a tumor of mixed histopathologic type or a type that is not otherwise specified should be classified as squamous cell carcinoma.
