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; ureters
