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 IV, leave T and N blank and see M **Note 2:** Code only regional nodes and nodes, NOS, in this field. Regional nodes include bilateral and contralateral involvement of named nodes. Distant nodes, including presacral and lateral sacral (laterosacral) nodes, are coded in M (distant metastasis). **Note 3:** If the clinician says "adnexa palpated" but does not mention lymph nodes, assume lymph nodes are clinically negative (cN0). **Regional lymph nodes** Aortic, NOS Lateral (lumbar) Para-aortic Periaortic Iliac, NOS Common External Internal (hypogastric) Obturator Inguinal Pelvic, NOS RetroperitonealNAACCR Item
