Clinical T

This input is used for staging


**Note 1:** FIGO does not include an in situ category for tumors of the vagina, but TNM does. Assign pTis (behavior code /2) for in situ cases. **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 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:** The presence of bullous edema is not sufficient evidence to classify a tumor as T4. **Note 4:** The pelvic wall is defined as muscle, fascia, neurovascular structures, or skeletal portions of the bony pelvis.
