CS Extension

Notes

**Note 1**: When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension detail are available, record the code with extension detail in preference to a statement of FIGO stage. FIGO Stage IVA is assigned based on tumor extension and/or regional lymph node involvement. Code CS Extension based on a physician's statement of FIGO Stage IVA if it is based on tumor extension or the basis is unknown. **Note 2**: FIGO no longer includes Stage 0 (Tis) for this site. **Note 3**: FIGO Stage I, IA and IB are defined by size of tumor, involvement of vulva OR vulva and perineum, and 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. **Note 5**: Use codes 110, and 120 in preference to 125 and 125 in preference to code 200.

- For CS Extension codes 110, 125-410, 425-450, and 470 ONLY, the T category for AJCC 7 staging is assigned based on the value of CS Tumor Size and CS Extension, as shown in the Extension Size AJCC 7 Table for this schema. - For CS Extension codes 110-470 ONLY, the T category for AJCC 6 staging is assigned based on the value of CS Tumor Size and CS Extension, as shown in the Extension Size AJCC 6 Table for this schema.
