Pathologic N
This input is used for staging
Notes
**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and regional lymph node detail are available, use the regional lymph node detail in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO stage III [NOS] or IIIC, assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is FIGO stage IV, leave T and N blank and see M **Note 2:** Histological examination of a pelvic lymphadenectomy specimen will ordinarily include 6 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0. (FIGO classifies such cases as pNX). (1) **Note 3:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis). **Regional lymph nodes** Intra-abdominal Para-aortic Pelvic Subdiaphragmatic Iliac Common iliac External iliac Internal iliac (hypogastric): Obturator Inguinal Retroperitoneal, NOSNAACCR Item
NAACCR #890Pathologic 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 OR Involvement of regional lymph nodes not documented Physician assign pNX, no other information available to determine N |
p0 | pN0 | No regional lymph node metastasis | Only information available is FIGO Stage IIIA or IIIB |
p1 | pN1 | Regional lymph node metastasis | Regional lymph nodes, NOS Lymph nodes, NOS Stated as N1 |
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 | Only information is FIGO Stage III [NOS], IIIC, or IV Pathologic classification 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 |
