STAGE I : carcinoma strictly confined to the cervix
STAGE II : cancer spread beyond the cervix , but not to pelvic wall or lower third
Of vagina .
STAGE III : tumor extends to the lateral pelvic wall , involves the lower third of
Vagina and/or causes hydronephrosis or non functioning kidney .
STAGE IV : tumor extends beyond true pelvis .
STAGE I has IA and IB . IA has IA 1 and IA2 , IB has IB 1 and IB 2 .
STAGE II has IIA and IIB
STAGE III has IIIA and IIIB
STAGE IV has IVA and IVB .
STAGE IA – microinvasive carcinoma , stromal invasion not exceeding 5.0 mm
From the base . lateral spread not exceeding 7.0 mm . vascular or
Lymphatic involvement does not alter classification .
Stage IA 1 – measured stromal invasion of less than 3.0 mm in depth and less than
7.0 mm in horizontal spread .
Stage IA 2 – measured stromal invasion between 3-5 mm in depth and not exceeding
7.0 mm in horizontal spread
STAGE IB - clinically visible lesion confined to the cervix or microscopic lesion
Greater than stage IA 2 .
Stage IB 1 – clinically visible lesion 4.0 cm or less in size
Stage IB 2 – clinically visible lesion more than 4.0 cms in dimension
STAGE IIA – tumor without parametrial invasion (vagina lower third not involved)
STAGE IIB – tumor with parametrial invasion (vagina lower third not involved)
STAGE IIIA – tumor involves lower third of the vagina , no extension to the lateral
Pelvic wall
STAGE IIIB – tumor extends to pelvic wall and / or involves kidney .
STAGE IVA – tumor involves bladder / rectum or spreads beyond the pelvis
STAGE IV B – widespread tumor with distant metastases
