Collaborative Stage for TNM 7 - Revised 01/24/2010 [ Schema ]

SinusEthmoid

CS Extension

Note 1: Involvement of or extension to bone includes any type of tumor extension to the bone, such as erosion, invasion, extension, penetration, or destruction.
Note 2: Extension to structures in codes 400 and higher may be from one or both ethmoid sinuses.
Note 3: In code 700, "minimal extension to anterior cranial fossa" implies tumor pushing through cribriform plate, but without invasion of the dura or brain.
Note 4: Code Base of skull NOS only if no information available to code to more specific bony structures in skull.
Note 5: Use code 300 for localized tumor ONLY if no information is available to assign codes 100, 120, 160, or 315.
Note 6: Use code 315 410, 680, 725, 810, or 815 if the physician's assignment of T category is the ONLY information available about the extent of the tumor.
