Pathologic T
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 T 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. If the only information is FIGO stage IV, leave T and N blank and see M **Note 2:** FIGO does not include an in situ category for tumors of the fallopian tube, but TNM does. Assign pTis (behavior code /2) for in situ cases. **Note 3:** Liver capsule metastasis is T3/Stage III, liver parenchymal metastasis, M1/Stage IV. **Note 4:** Both extension to and discontinuous metastasis to any of the following pelvic organs are assigned as FIGO Stage II and coded in T2a or T2b. * Adnexa, NOS; bladder, bladder serosa; broad ligament (mesovarium); cul de sac; contralateral fallopian tube; parametrium; pelvic peritoneum; pelvic wall; rectum; sigmoid colon; sigmoid mesentery; ureter; uterus; uterine serosa **Note 5:** Both extension to and discontinuous metastasis to any of the following abdominal organs are classified as FIGO Stage III and coded in T3. * Abdominal mesentery; diaphragm; gallbladder; infracolic omentum; kidneys; large intestine except rectum and sigmoid colon; liver (peritoneal surface); omentum; pancreas; pericolic gutter; peritoneum, NOS; small intestine; spleen; stomach; uretersNAACCR Item

FIGO Stage IIC Stated as T2c |
| p3 | pT3 | Tumor involves one or both fallopian tube(s) WITH peritoneal implants outside the pelvis and/or positive regional lymph nodes |
Note: T3 has subcategories of T3a, T3b and T3c. Assign T3 only when there is no information available to assign one of the subcategories Peritoneal implants or metastasis outside the pelvis, size of metastasis not stated, unknown if microscopic or macroscopic: Omentum Small intestine Further contiguous extension Stated as T3 [NOS] |
