Collaborative Stage

Collaborative Stage for TNM 7 - Revised 09/03/2010 [ Schema ]

Extension Size Table

For CS Extension codes 100-140, 200, and 300 ONLY, the T category for AJCC 6 and AJCC 7 staging is assigned based on the value of CS Tumor Size, as shown in the this table. A CS Tumor Size code takes precedence over a CS Extension "stated as T" code; however, if CS Tumor Size is coded as unknown, the T category may be assigned based on "stated as T" recorded in CS Extension.
