Vulvar Cancer FIGO 2021 Stage
Primary lesion (when confined to vulva/perineum)
Local spread
Inguinofemoral nodes
Fixation / distant
When to use
Staging and management direction for vulvar carcinoma under the FIGO 2021 system.
How it works
I confined to vulva (IA ≤ 2 cm and ≤ 1 mm invasion / IB > 2 cm or > 1 mm, nodes negative); II lower 1/3 urethra/vagina/anus; III upper 2/3 structures or nodes (IIIA ≤ 5 mm or upper 2/3, IIIB > 5 mm, IIIC extracapsular); IVA fixation/fixed-ulcerated nodes, IVB distant.
Key points
- FIGO 2021 aligned vulvar nodal-metastasis size definitions with the cervical system and subdivided stage III into A/B/C.
- IA (invasion ≤ 1 mm) carries a very low nodal-metastasis risk and generally needs no groin node assessment.
- Sentinel-node biopsy is standard for eligible IB+ unifocal tumours with clinically negative groins.
- Positive margins or nodes drive adjuvant (chemo)radiation to the groins/pelvis.
