FIGO Staging of Carcinoma of the Cervix Uteri
Preinvasive Carcinoma
Stage O Carcinoma in situ, intraepithelial carcinoma (Case of stage O should not be
included in any therapeutic statistics).
Invasive Carcinoma
Stage I Carcinoma strictly confined to the cervix (extension to the corpus should be disregarded).
Stage Ia Preclinical carcinomas of the cervix, that is, those diagnosed
only by microscopy.
Stage Ia l Minimal microscopically evident stromal invasion
Stage Ia 2 Lesions detected microscopically that can be measured.
The upper limit of the measurement should not show a depth of invasion of more than 5 mm taken from the base
of the epithlium, either surface or glandular, from which it
originates, and a second dimension, the horizontal spread,
must not exceed 7 mm. Larger lesions should be staged
as Ib.
Stage Ib Lesion of greater dimensions than Stage Ia2 whether seen clinically
or not. Preformed space involvement should no after the staging but
should be specifically recorded so as to determine whether it should
affect treatment decisions in the future.
Stage II The carcinoma extends beyond the cervix but has not extended on to the wall.
The carcinoma involves the vagina, but not the lower third
Stage II No obvious parametrial involvement.
Stage IIb Obvious parametrial involvement.

Stage III The carcinoma has extended on to the pelvic wall. On rectal examination, there is no cancer-free space between the tumor and the pelvic side wall. The tumor involves the lower third of the vagina. All cases with hydronephrosis or nonfunctioning kidney.
Stage IIIa No extension to the pelvic side wall.
Stage IIIb Extension on to the pelvic side wall and/or hydronephrosis or
nonfunctioning kidney.
Stage IV The carcinoma has extended beyond the true pelvis or has clinically involved the
mucosa of the bladder or rectum. A bullous edema as such does not permit a case
to be allotted to stage IV.
Stage IVa Spread of the growth to adjacent organs.
Stage IVb Spread to distant organs
