Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/15/2009 [ Schema ]

CS Mets at DX

Note 1: All lymph node involvement is considered M1b in TNM. Therefore lymph node involvement, whether regional or distant nodes, is coded in the field CS Mets at DX.
Note 2: According to AJCC, metastasis to genital structures is considered T2 and not M1 for GTT. For this Collaborative Staging schema, metastasis to genital structures is coded 700 in CS Extension and not coded in CS Mets at DX.
