Clinical 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 FIGO III [NOS] or IIIC 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 3:** Tumor size must be known to assign a value of T1a or T1b. You may use a physician’s statement of the T category if this is the only information in the medical record. * If the tumor appears to be in the T1 category, but no size or category is specified, assign T1
