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 [NOS] or IIIC 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). **Note 3:** Regional nodes include bilateral and contralateral involvement of named nodes. **Note 4:** 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
