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], IIIC [NOS], IIIC1 or IIIC2, 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
