This input is used for staging

Notes

**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and metastatic detail are available, use the metastatic detail in preference to a statement of FIGO stage - see Registrar notes. **Note 2:** Genital metastasis (vagina, ovary, broad ligament, fallopian tube) are classified as T2. Any involvement of non-genital structures, whether by direct invasion or metastasis are assigned in M (distant metastasis). **Note 3:** All lymph node involvement for GTT is coded as M1b.
