Notes:
● As of June 2012, there are updated College of American Pathologists (CAP) protocols for both appendiceal adenocarcinomas and well-differentiated neuroendocrine tumors (NET) of the appendix: visit CAP.org and search for "Cancer Protocols and Checklists"
● Staging for NETS does not include poorly differentiated (high-grade, G3) neuroendocrine carcinomas, small cell carcinomas, and goblet cell carcinoids (use CAP protocol for appendiceal carcinomas)
