Pathologic T

This input is used for staging

Notes

**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM nor FIGO include an in situ category for ovary tumors. **Note 2:** 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 T in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO IIIC, assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is FIGO stage IV, leave T and N blank and see M **Note 3:** T1 and T2 tumors with malignant ascites are classified as T1c and T2c (FIGO Stages IC and IIC), respectively. * Ascites, NOS is negative **Note 4:** Both extension to and discontinuous metastasis to any of the following pelvic organs are included in the T2 category (FIGO Stage II). * Adnexa, NOS; bladder and bladder serosa; broad ligament (mesovarium); cul de sac; fallopian tubes; parametrium; pelvic peritoneum; pelvic wall; rectosigmoid; rectum; sigmoid colon; sigmoid mesentery; pelvic ureter; uterus and uterine serosa **Note 5:** Peritoneal implants outside the pelvis must be microscopically confirmed. * Peritoneal implants may also be called seeding, salting, talcum powder appearance, or studding **Note 6:** If implants are mentioned, determine whether they are in the pelvis or in the abdomen and code appropriately. * If the location of the implants are not specified, assign T3 **Note 7:** Both extension to and discontinuous metastasis to any of the following abdominal organs by way of peritoneal seeding or implants are included in the T3 category (FIGO Stage III). * 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 * Residual tumor in any of these organs are classified as FIGO III and coded in T3 and in **Site-Specific Factors 3 and 4**. (Hematogenous metastases are included in M1 (FIGO Stage IV) disease **Note 8:** Parenchymal liver nodules are coded in M (distant metastasis). **Note 9:** In some registries benign/borderline ovarian tumors are reportable by agreement. * If the tumor being reported is benign or borderline, code primary tumor to TX
