Histologies Stage Table
Notes
**Note 1**: The determination of AJCC stage group from T, N, M, and grade for EsophagusGEJunction 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.Histology | ajcc7_stage |
