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 CS Lymph Nodes codes 100-500 ONLY, the N category for AJCC 7 staging is assigned based on the values of CS Site-Specific Factor 5, Size of Metastasis in Lymph Nodes, Regional Nodes Positive, and CS Lymph Nodes Eval. If the CS Lymph Nodes Eval code is 2 (p), 3 (p), 6 (yp), or 8 (a), the N category is determined by using the Lymph Nodes Pathologic Evaluation Table. If the CS Lymph Nodes 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 CS Lymph Nodes Eval field is not coded, the N category is determined by using the Lymph Nodes Positive Eval Blank Table.
* For CS Lymph Nodes codes 100-500 ONLY, the N category for AJCC 6 staging is assigned based on the values of CS Site Specific Factor 5, Size of Metastasis in Lymph Nodes, Regional Nodes Positive and CS Lymph Nodes Eval. If the CS Lymph Nodes Eval code is 2 (p), 3 (p), 6 (yp), or 8 (a), the N category is determined by using the Lymph Nodes Pathologic Evaluation Table. If the CS Lymph Nodes 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 CS Lymph Nodes Eval field is not coded, the N category is determined by using the Lymph Nodes Positive Eval Blank Table.
