Collaborative Stage Data Set - Revised 11/20/2010 FINAL

Anus

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: Use codes for anal canal unless tumor is stated to occur at the anus, arising just proximal to the squamous mucocutaneous junction or the anal verge.
Note 3: For codes 400 and 405, the combination of unilateral internal iliac nodes and unilateral inguinal nodes must be on the same side. Use code 530 for bilateral combinations of internal iliac nodes and inguinal nodes.
Note 4: Use codes for internal iliac nodes for combinations of perirectal and internal iliac nodes. Use codes 415, 425, and 440 for combinations of perirectal and superficial inguinal nodes.
