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 FIGO III, assign the appropriate stage and leave clinical T, N, and M blank. If the only information is FIGO stage IVB, leave T and N blank and see M. **Note 2:** 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)NAACCR Item
