Pathologic N

This input is used for staging

Notes

**Note 1:** Involvement of inguinal, pelvic, or external iliac lymph nodes **WITHOUT** previous scrotal or inguinal surgery prior to presentation of the testis tumor is coded in M (distant metastasis), as distant lymph node involvement. **Note 2:** Size of the largest metastasis in a lymph node must be known to assign N. You may use a physician’s statement of the N category if this is the only information in the medical record. * If the size of the metastasis is not documented, determine the size of the largest involved lymph node as documented pathologically * If the size of the lymph node(s) cannot be determined, assign N1 * Do **not** code the size of any node(s) assigned in M (distant metastasis) **Regional lymph nodes** Aortic, NOS Lateral (lumbar) Para-aortic Periaortic Preaortic Retroaortic Pericaval, NOS Interaortocaval Paracaval Precaval Retrocaval Retroperitoneal, NOS Spermatic vein Regional lymph nodes, NOS Lymph nodes, NOS **Regional lymph nodes WITH previous scrotal or inguinal surgery** External iliac Inguinal nodes, NOS Deep, NOS Node of Cloquet or Rosenmuller (highest deep inguinal) Superficial (femoral) Pelvic, NOS

Pathologic N	Pathologic N Display	Description	Registrar Notes
pX	pNX	Regional lymph nodes cannot be assessed	Pathologic classification criteria met, evaluation done: Physician unable to assess N Surgical resection primary tumor, no regional lymph nodes removed Involvement of regional lymph nodes not documented Physician assigns pNX, no other information available to determine N
p0	pN0	No regional lymph node metastasis
p1	pN1	Metastasis with a lymph node mass 2 or less in greatest dimension OR 5 or fewer positive nodes, none more than 2 cm in greatest dimension	Single or multiple nodes not stated, size not stated Stated as N1
p2	pN2	Metastasis with a lymph node mass more than 2 cm but not more than 5 cm in greatest dimension OR More than 5 nodes positive, none more than 5 cm in greatest dimension OR Evidence of extranodal extension of tumor	Single or multiple nodes not stated, size stated and greater than 2 cm but less than or equal to 5 cm Stated as N2
p3	pN3	Metastasis with a lymph node mass more than 5 cm in greatest dimension	Stated as N3
c0	cN0	Clinically: No regional lymph node metastasis	Use only for TNM defined pTis cases where there is a resection of the primary and the nodes are not evaluated pathologically
88	88	Not applicable	Primary site/histology not TNM defined Death certificate only (DCO) case
<BLANK>	BLANK	See Registrar Notes	Pathologic classification criteria not met No surgical resection of primary tumor and there isn’t a positive biopsy of a structure in the highest T category and highest N category Evidence of metastatic disease (pM1), no other workup Only Pathologic Stage Group documented (no T, N, or M information available)
