Collaborative Stage for TNM 7 - Revised 10/29/2010 [ Schema ]
Esophagus
Histologies Stage Table
- Note 1: The determination of the AJCC 7 stage group from T, N, M, and grade for esophagus depends further on histologic type. Since squamous cell carcinoma typically has a poorer prognosis than adenocarcinoma, a tumor of mixed histopathologic type (including a squamous component or NOS histology) or a type that is not otherwise specified should be staged as squamous cell carcinoma.
- Note 2: 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.
