Collaborative Stage for TNM 7 - Revised 12/13/2009 [ Schema ]

Vulva

CS Lymph Nodes

Note: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field Mets at DX. The regional nodes are inguinal or femoral: inguinal, NOS; deep inguinal, NOS; Node of Cloquet or Rosenmuller (highest deep inguinal); and superficial inguinal (femoral) and regional lymph nodes [NOS].

* CS Lymph node codes 110-450 and 600 are used in conjunction with CS Site Specific Factor 11 (Regional Lymph Node - Laterality) to determine the N code for AJCC 6th edition - see CS AJCC 6th CS Lymph Nodes and SSF 11 Table.
