FIGO 1988 versus 2009 staging for endometrial carcinoma: a comparative study on prediction of survival and stage distribution according to histologic subtype

摘要

ObjectiveThe surgical staging system for endometrial carcinoma developed by International Federation of Gynecology and Obstetrics (FIGO) in 1988 was revised in 2009. Given the importance of continuous validation of the prognostic performance of staging systems, we analyzed the disease specific survival for patients with endometrial carcinoma using FIGO 1988 and 2009 systems. Further, the stage distribution of endometrioid and nonendometrioid carcinomas was studied.
