Pathologic N
This input is used for staging
Notes
**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the T in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO III [NOS], IIIC [NOS], IIIC1, or IIIC2 assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is FIGO stage IVB, 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). **Note 4:** Regional nodes include bilateral and contralateral involvement of named nodes. **Note 5:** If the clinician says "adnexa palpated" but does not mention lymph nodes, assume lymph nodes are not involved. **Regional lymph nodes** Aortic, NOS Lateral (lumbar) Para-aortic Periaortic Iliac, NOS Common External Internal (hypogastric) Obturator Paracervical Parametrial Pelvic, NOS Sacral, NOS Lateral (laterosacral) Middle (promontorial) (Gerota's node) Presacral Uterosacral Pelvic lymph nodes, NOS FIGO Stage IIIC (pelvic or para-aortic lymph nodes) FIGO Stage IIIC1 (pelvic lymph nodes) FIGO Stage IIIC2 (para-aortic lymph nodes WITH or WITHOUT pelvic lymph nodes)NAACCR Item
NAACCR #890| Pathologic N | Pathologic N Display | Description | Registrar Notes |
|---|---|---|---|
| pX | pNX | Regional lymph nodes cannot be assessed | Only information available is FIGO Stage IVA 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 I [NOS], IA, IB, II, IIIA, IIIB |
| p1 | pN1 | Metastasis to pelvic or para-aortic lymph nodes (IIIC) Metastasis to pelvic lymph nodes (IIIC1) |
Regional lymph nodes, NOS Lymph nodes, NOS Stated as N1 |
| p2 | pN2 | Metastasis to para-aortic lymph nodes with or without metastasis to pelvic lymph nodes (IIIC2)^ | Stated as N2 |
| 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 [NOS], IIIC1, IIIC2, or IVB 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 |
