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 or peritoneal carcinomatosis may also be called seeding, salting, talcum powder appearance, or studding - Extraperitoneal carcinomatosis are coded in EOD Mets **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 - Adjacent pelvic (peritoneum) - Bladder - Bladder serosa - Cul de sac (rectouterine pouch) - Ligament(s) (broad, ovarian, round, suspensory) - Mesosalpinx (Meosvarium) - Parametrium - Pelvic wall - Rectosigmoid - Rectum - Sigmoid colon (including sigmoid mesentery) - Ureter (pelvic portion) **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, rectosigmoid and sigmoid colon) - Kidneys - Omentum (infracolic, NOS) - Pancreas - Pericolic gutter - Peritoneum, NOS - Small intestine - Stomach - Ureters (outside pelvis) **Note 7:** Tumor limited to the peritoneal surface of the liver or splenic capsule is coded 700, regardless of the size (microscopic or macroscopic) - Any **parenchymal** involvement of the liver or spleen is coded in EOD Mets (code 50)Default
