e-CASES: FIGO Classification 2009 - Cervix uteri

Dr Antoine Micheau , CHU Arnaud de Villeneuve , Montpellier , Herault , France

Stage I

The carcinoma is strictly confined to the cervix (extension to the corpus would

be disregarded)

- IA Invasive carcinoma which can be diagnosed only by microscopy, with deepest

invasion <5 mm and the largest extension >7 mm

- IA1 Measured stromal invasion of <3.0 mm in depth and extension of <7.0 mm

- IA2 Measured stromal invasion of >3.0 mm and not >5.0 mm with an extension of

not >7.0 mm

- IB Clinically visible lesions limited to the cervix uteri or pre-clinical cancers

greater than stage IA

- IB1 Clinically visible lesion <4.0 cm in greatest dimension

- IB2 Clinically visible lesion >4.0 cm in greatest dimension

 

Stage II

Cervical carcinoma invades beyond the uterus, but not to the pelvic wall or to the lower

third of the vagina

- IIA Without parametrial invasion

- IIA1 Clinically visible lesion <4.0 cm in greatest dimension

- IIA2 Clinically visible lesion >4.0 cm in greatest dimension

- IIB With obvious parametrial invasion

 

 

Stage III

The tumour extends to the pelvic wall and/or involves lower third of the vagina and/or

causes hydronephrosis or non-functioning kidney

- IIIA Tumour involves lower third of the vagina, with no extension to the pelvic wall

- IIIB Extension to the pelvic wall and/or hydronephrosis or non-functioning kidney

 

Stage IV

The carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the

mucosa of the bladder or rectum.

- IVA Spread of the growth to adjacent organs

- IVB Spread to distant organs
