Staging is based on clinical examination, cystoscopy, proctoscopy and chest X-ray
Stage 0
TIS; Carcinoma in situ, Grade III Intraepithelial Neoplasia
Stage I
Tumour limited to the vaginal wall
Stage II
Tumour has extended to subvaginal tissue but has not extended to the pelvic wall
Stage III
Tumour extended to the pelvic wall
Stage IV
Stage IVA: Tumour invasion of bladder and/or bowel mucosa
Stage IVB: Distant metastases (disease outside the true pelvis)
Most of the vaginal malignancies (84%) are secondary and arise from the cervix, the endometrium, the colon/rectum, the ovary or the vulva. These tumours are NOT considered as a primary vaginal sarcoma.
