- Note 1: For this schema, AJCC only stages well-differentiated neuroendocrine tumors. Note that the "concept" of well-differentiated is reflected in the histology code. The grade code is not needed in order to select the correct schema, but does need to be coded.
- Note 2: This schema is also used for carcinoid tumors and malignant gastrinomas.
