Clinical 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 FIGO III [NOS], IIIC [NOS], IIIC1, or IIIC2 assign the appropriate stage and leave clinical T, N, and M blank. If the only information is FIGO stage IVB, leave T and N blank and see M **Note 2:** FIGO does not include an in situ category for tumors of carcinomas of the corpus uteri, but TNM does. Assign pTis and behavior code /2 for in situ cases. **Note 3:** To assign a T2 category, stromal connective tissue of the cervix must be involved; endocervical glandular involvement only is not classified as a T2 tumor in TNM. **Note 4:** Extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.
