**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and metastatic detail are available, use the metastatic detail in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO III [NOS] or IIIC, assign the appropriate stage and leave pathologic T, N, and M blank **Note 2:** Discontinuous metastasis to any of the following abdominal organs by way of peritoneal seeding or implants is included in the T3 category (FIGO Stage III) and coded in primary tumor. * Abdominal mesentery; diaphragm; gallbladder; infracolic omentum; kidneys; large intestine except rectum, rectosigmoid, and sigmoid colon; liver (peritoneal surface); omentum; pancreas; pericolic gutter; peritoneum, NOS; small intestine; spleen; stomach; and ureters outside pelvis * Hematogenous metastases are included in M1 (FIGO Stage IV) disease **Distant lymph nodes** Sacral lymph nodes Presacral lymph nodes Lateral sacral (laterosacral) Sacral NOSNAACCR Item
