CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in CS Mets at DX.
Note 2: 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].
Note 3: When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and regional lymph node detail are available, record the code with regional lymph node detail in preference to a statement of FIGO stage. FIGO Stage IVA is assigned based on tumor extension and/or regional lymph node involvement. Code CS Lymph Nodes based on a physician's statement of FIGO Stage IVA only if it is known that the stage value is assigned because of regional lymph node involvement.

* CS Lymph Nodes codes 110-450 are used in conjunction with CS Site Specific Factor 11,Regional Lymph Node Laterality, to determine the N category for AJCC 6 staging as shown in the Lymph Nodes SSF 11 AJCC 6 Table.
