Background: The revised FIGO staging system for carcinoma of the vulva, cervix uteri, and endometrium, which had been previously revised in 1988, 1994, and 1988, respectively, was approved by the International Federation of Gynecology and Obstetrics (FIGO) in September 2008. In addition to the revisions of previously existing staging systems, a new staging system for uterine sarcomas was introduced at the same time. Conclusions: The changes mostly addressed the prognostic disproportions between certain (sub) stages that had been shown in numerous statistical analyses. Vulvar cancer staging has undergone the greatest changes.
