Collaborative Stage

Collaborative Stage for TNM 7 - Revised 05/13/2011 [ Schema ]

MelanomaSinusEthmoid

CS Extension

Note 1: AJCC does not include a Tis or TX category for melanoma of mucosa of head and neck sites. CS Extension codes of 000 and 999 are mapped to NA and AJCC stage group is derived as NA.
Note 2: AJCC does not include a T1 or T2 category for mucosal melanoma of head and neck sites.
Note 3: Extension to structures in codes 180, 185, and 400 and higher may be from one or both ethmoid sinuses.
Note 4: Use codes 180 and 185 for extension involving the mucosa only of adjacent sites. Use higher codes for extension involving the deeper tissues of the primary or adjacent sites.
Note 5: Use code 170 for localized tumor only if no information is available to assign codes 105, 165, 190, 200, or 210.
Note 6: Use code 190, 725, 810, or 815 if the physician's assignment of T category is the only information available about the extent of the tumor.
