   - 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.
