FIGO Stage

Description

I

Tumour confined to the vulva, no nodal metastasis

IA
Lesion < 2cm in size, confined to the vulva or perineum and with stromal invasion <1mm

IB
Lesion >2cm in size or with stromal invasion >1mm, confined to the vulva or perineum
II

Tumour of any size with extension to adjacent perineal structures (lower third urethra, lower third vagina, anus), with negative nodes
III

Tumour of any size with extension to upper part of adjacent perineal structures or with positive inguinofemoral nodes

IIIA
Tumour of any size with disease extension to upper two-thirds of the urethra, vagina or anus
Or regional lymph node metastases <5mm

IIIB
Regional lymph node metastases >5mm

IIIC
Regional lymph node metastases with extracapsular spread
IV

Tumour invades other regional (upper 2/3 urethra, upper 2/3 vagina) or distant structures

IVA
Disease fixed to pelvic bone or fixed to ulcerated inguinofemoral lymph nodes

IVB
