NCIt synonyms : Anal Carcinoma by AJCC v8 Stage; Anal Canal and Perianal (Anal Margin) Carcinoma by AJCC v8 Stage;
NCIt definition : A term that refers to the staging of anal cancer according to the American Joint Committee
on Cancer, 8th edition. This staging system applies to all carcinomas arising in the
anal canal, including carcinomas that arise within anorectal fistulas and those arising
in the perianal area (anal margin). High-grade neuroendocrine carcinomas (small cell
neuroendocrine carcinoma and large cell neuroendocrine carcinoma) are staged using
this system. There is no AJCC staging system for anal mucosal melanomas and anal well-differentiated
neuroendocrine tumors. (from AJCC 8th Ed.);
