Does the FIGO 2009 endometrial cancer staging system more accurately correlate with clinical outcome in different histologies? Revised staging, endometrial cancer, histology.

Objective: In 2009, the International Federation of Gynecology and Obstetrics (FIGO) staging system was revised for endometrial cancers. Different histologies were examined in a large population database. The FIGO 1988 and 2009 staging systems were compared for stage at presentation, differences in patient populations, and disease-specific survival (DSS).
