Cervical Cancer Staging: Likelihood Ratios

Introduction: For screening and initial diagnosis of Cervical Cancer, see that page.

The FIGO staging system is clinical and is as follows, in brief:

Stage I - confined to uterus

Stage II - invades beyond uterus but not to pelvic wall or to the lower third of vagina

Stage III - Tumor extends to the pelvic wall, and/or involves the lower third of the vagina, and/or causes hydronephrosis or nonfunctioning kidney

Stage IV - extension beyond the true pelvis or has involved (biopsy proven) the bladder mucosa or rectal mucosa
