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 sarcomas of the corpus. **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 (pathologic) FIGO stage IVB, leave pathologic T and N blank and see M **Note 3:** Extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.

\* TX is not defined by UICC in the 7th edition. Approval has been provided by UICC to use the standard definition "Primary tumor cannot be assessed," as TX. \** T0 is not defined by UICC in the 7th edition. Approval has been provided by UICC to use the standard definition "No evidence of primary tumor," as T0.
