EOD Primary Tumor
This input is used for staging
Notes
**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the code in preference to a statement of FIGO stage. **Note 2:** Peritoneal implants may also be called seeding, salting, talcum powder appearance, or studding. **Note 3:** A tumor confined to the peritoneum (code 300) is when there is one pelvic peritoneal tumor, or multiple pelvic peritoneal tumors, without any mention of implants on the specific pelvic/abdominal structures listed in codes 400-750. **Note 4:** Both extension to and/or discontinuous metastasis to any of the following pelvic organs are included in code 450 - Adnexa, NOS - Bladder and bladder serosa - Broad ligament (mesovarium) - Cul de sac - Parametrium - Pelvic peritoneum - Pelvic wall - Rectosigmoid - Rectum - Sigmoid colon - Sigmoid mesentery - Ureter, pelvic **Note 5:** If implants are mentioned, determine whether they are in the pelvis or in the abdomen and code appropriately. If the location of the implants is not specified, code 750. **Note 6:** Both extension to and/or discontinuous metastasis to any of the following abdominal organs by way of peritoneal seeding or implants are included in codes 600-750 - Abdominal mesentery - Diaphragm - Gallbladder - Intestine, large (except rectum) - Kidneys - Liver (peritoneal surface) - Omentum (infracolic, NOS) - Pancreas - Pericolic gutter - Peritoneum, NOS - Rectosigmoid - Sigmoid colon - Small intestine - Spleen (capsular involvement only) - Stomach - Ureters (outside pelvis) **Note 7:** Direct extension and/or metastasis to the liver or splenic parenchyma are coded in EOD Mets.Default
