Clinical T
This input is used for staging
Notes
**Note 1:** FIGO does not include an in situ category for tumors of the vulva, 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 [NOS], IIIA, IIIB, IIIC, or IVA, 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:** FIGO Stage I, IA and IB are defined by the following * Size of tumor * Involvement of vulva OR vulva and perineum * Depth of stromal invasion **Note 4:** The depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion. (1) **Note 5:** T3 is not used by FIGO. They label it T4. If you have a record which states T4, assign T3. (1) **Note 6:** FIGO Stage IVA is assigned based on tumor extension and/or regional lymph node involvement.NAACCR Item
