Collaborative Stage

Note 1: Regional nodes in codes 100-300 include contralateral and bilateral nodes.
Note 2: Involvement of inguinal, pelvic, or external iliac lymph nodes (codes 300 and 400) WITHOUT previous scrotal or inguinal surgery prior to presentation of the testis tumor is coded in CS Mets at DX, as distant lymph node involvement.

^ For codes 100, 200, 300, 350, 400, 500, and 800 ONLY, the N category for AJCC 7th Edition is assigned based on the values of Site-Specific Factor 5 (Size of Metastasis in Lymph Nodes), Reg LN Pos and CS Lymph Nodes Eval. If the Eval code is 2 (p), 3 (p), 6 (y), or 8 (a), the N category is determined by using the Lymph Nodes Pathologic Evaluation Table. If the Eval code is 0 (c), 1 (c), 5 (c), or 9 (c), the N category is determined by using the Lymph Nodes Clinical Evaluation Table. If the Eval field is not coded, the N category is determined by using the Lymph Nodes Positive Eval Blank Table.
* For codes 100, 200, 300, 350, 400, 500, and 800 ONLY, the N category for AJCC 6th Edition is assigned based on the values of Site Specific Factor 5 (Size of Metastasis in Lymph Nodes), Reg LN Pos and CS Lymph Nodes Eval. If the Eval code is 2 (p), 3 (p), 6 (y), or 8 (a), the N category is determined by using the Lymph Nodes Pathologic Evaluation Table. If the Eval code is 0 (c), 1 (c), 5 (c), or 9 (c), the N category is determined by using the Lymph Nodes Clinical Evaluation Table. If the Eval field is not coded, the N category is determined by using the Lymph Nodes Positive Eval Blank Table.
