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 TXNAACCR Item

| p2A | pT2a | Extension and/or implants on uterus and/or tube(s) No malignant cells in ascites or peritoneal washings |
Extension to or implants on (but no malignant cells in ascites or peritoneal washings): Adnexa, ipsilateral, contralateral or NOS Fallopian tube(s), ipsilateral, contralateral or NOS Uterus FIGO Stage IIA Stated as T2a |
| p2B | pT2b | Extension to other pelvic tissues No malignant cells in ascites or peritoneal washings |
Extension to or implants on other pelvic structures (but no malignant cells in ascites or peritoneal washings): Bladder Bladder serosa Cul de sac Pelvic tissue: Adjacent peritoneum Ligament(s): Broad, ipsilateral, contralateral or NOS Ovarian Round Suspensory Mesovarium, ipsilateral, contralateral or NOS Parametrium Pelvic wall Rectosigmoid, Rectum Sigmoid colon Sigmoid mesentery Ureter (pelvic portion) FIGO Stage IIB Stated as T2b |

| p3 | pT3 | Tumor involves one or both ovaries WITH microscopically confirmed peritoneal metastasis outside the pelvis and/or regional lymph node metastasis |
Note: T3 has subcategories of T3a, T3b and T3c. Assign T3 only when there is no information available to assign one of the subcategories Further contiguous extension Stated as T3 [NOS] |
| p3A | pT3a | Microscopic peritoneal metastasis beyond pelvis | Peritoneal surface/capsule of liver FIGO Stage IIIA Stated as T3a |
