Stage Information for Vaginal Cancer

Definitions: FIGO
        FIGO staging system (and modified World Health Organization [WHO] prognostic scoring system)

If the cervix is intact, biopsies are mandatory to rule out a primary carcinoma of the cervix. Carcinoma of the vulva should also be ruled out.

Definitions: FIGO

The Féderation Internationale de Gynécologie et d’Obstétrique (FIGO) and the American Joint Committee on Cancer (AJCC) have designated staging to define vaginal cancer; the FIGO system is most commonly used.[1,2] The definitions of the AJCC's T, N, and M categories correspond to the stages accepted by FIGO.

FIGO staging system (and modified World Health Organization [WHO] prognostic scoring system)

The FIGO staging system is as follows:[1]

Table 1. Carcinoma of the Vaginaa
FIGO Nomenclature 
Stage IThe carcinoma is limited to the vaginal wall.
Stage IIThe carcinoma has involved the subvaginal tissue but has not extended to the pelvic wall.
Stage IIIThe carcinoma has extended to the pelvic wall.
Stage IVThe carcinoma has extended beyond the true pelvis or has involved the mucosa of the bladder or rectum; bullous edemas as such does not permit a case to be allotted to stage IV.
IVa - Tumor invades bladder and/or rectal mucosa and/or direct extension beyond the true pelvis.
IVb - Spread to distant organs.

FIGO = Féderation Internationale de Gynécologie et d’Obstétrique.

In addition, the FIGO staging system incorporates a modified WHO prognostic scoring system. The scores from the eight risk factors are summed and incorporated into the FIGO stage, separated by a colon (e.g., Stage II:4, Stage IV:9, etc.). Unfortunately, a variety of risk scoring systems have been published, making comparisons of results difficult.
