Histologies Stage Table

Notes

**Note 1:** The determination of TNM 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 Stage table based on histology.
