Staging of cervical cancer can either be based on the TNM or FIGO system.
Revised FIGO staging of cervical carcinoma 2009 8
-
stage 0: cervical intraepithelial neoplasia
(CIN( HSIL or CIN III) -
stage I: confined to cervix
-
stage Ia: invasive carcinoma only diagnosed by microscopy.
- Ia1: stromal invasion <3 mm in depth and <7 mm in extension (microinvasive)
- Ia2: stromal invasion >3 mm depth and not >5 mm and extension <7 mm
-
stage Ib: clinically visible lesions limited to the cervix or pre-clinical cancers >stage 1a
- Ib1: clinically visible tumour <4 cm in greatest dimension
- Ib2: clinically visible tumour >4 cm in greatest dimension
-
stage Ia: invasive carcinoma only diagnosed by microscopy.
-
stage II: beyond cervix though not to the pelvic sidewall or lower third of the vagina.
-
stage IIa: involves upper 2/3rd of vagina without parametrial invasion
- stage IIa1: clinically visible tumour <4 cm in greatest dimension
- stage IIa2: clinically visible tumour >4 cm in greatest dimension
- stage IIb: with parametrial invasion
-
stage IIa: involves upper 2/3rd of vagina without parametrial invasion
-
stage III
- stage IIIa: tumour involves the lower third of the vagina with no extension to pelvic sidewall
- stage IIIb: extension to pelvic side wall or causing obstructive uropathy, MR imaging findings that are suggestive of pelvic sidewall involvement include tumour within 3 mm of or abutment of the internal obturator, levator ani, and pyriform muscles and the iliac vessel 6
-
stage IV: extension beyond true pelvis or biopsy proven to involve the mucosa of the bladder or the rectum
- stage IVa: extension beyond true pelvis or rectal/bladder invasion
- stage IVb: distant organ spread
