Collaborative Stage

Collaborative Stage for TNM 7 - Revised 01/04/2010 [ Schema ]

MelanomaSinusEthmoid

CS Extension

Note 1: AJCC does not include a Tis or TX category for melanoma of mucosa of head and neck sites. Extension codes of 000 and 999 will be mapped to NA and AJCC stage group will be derived as NA.
Note 2: AJCC does not include a T1 or T2 category for mucosal melanoma of head and neck sites.
Note 3: Involvement of or extension to bone includes any type of tumor extension to the bone, such as erosion, invasion, extension, penetration, or destruction.
Note 4: Extension to structures in codes 180, 185, and 400 and higher may be from one or both ethmoid sinuses.
Note 5: Code Base of skull NOS only if no information available to code to more specific bony structures in skull.
Note 6: Use code 170 for localized tumor ONLY if no information Is available to assign codes 105, 165 or 170.
Note 7: 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.
