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 III, assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is (pathologic) FIGO stage IVB, leave pathologic T and N blank and see M **Note 2:** Histological examination of an inguinal lymphadenectomy specimen will ordinarily include 6 or more lymph nodes; 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** Upper two thirds of vagina, regional nodes Pelvic lymph nodes Iliac, NOS Common External Internal (hypogastric) Obturator Middle sacral (promontorial) (Gerota's node) Pelvic lymph node(s), NOS Lower third of vagina, regional nodes Ipsilateral or bilateral Inguinal, NOS Superficial inguinal (femoral)
