22 - carcinoma cervix staging

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
