- stage Ia : stromal invasion by < 1 mm
- Stage Ib : stromal invsions by > 1 mm
stage II : tumours greater than 2cm but confined to vulva : corresponds to T2
stage III : any size with invasion of lower urethra, vagina, perineum, anus : correspinds to T3
stage IV : bladder / rectal invastion, fixation to bone and / or metastases
- stage IVa : invasion of bladder, upper urethra and rectal mucosa and / or fixation to bone : corresponds to T4
