Collaborative Stage for TNM 7 - Revised 09/26/2010 [ Schema ]

CS Extension

Note 1: The assignment of T1 and T2 categories for tumors of the oropharynx is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use codes 405, 410, 645, 735, 810, or 815 as appropriate to code CS Extension based on a statement of T when no other extension information is available.
Note 2: Use code 300 for localized tumor ONLY if no information is available to assign code 100, 200, 400, 405, or 410.

^ For CSExtension codes 100-600 ONLY, the T category for AJCC staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size AJCC 7 Table for this schema.
* For CS Extension codes 100-645 ONLY, the T category for AJCC 6 staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size AJCC 6 Table for this schema.
