September 2023—Understanding of the pathologic and molecular features of endometrial cancer has advanced measurably since the FIGO (International Federation of Gynecology and Obstetrics) staging system was updated in 2009. New treatments, results of clinical trials, and prognostic survival data that correlate with pathologic and surgical findings have been reported. Therefore, the FIGO Committee on Women’s Cancer determined that changes to the FIGO system were necessary. The goals of the revised staging system are to further clarify the diverse biologic nature of endometrial carcinomas with differing prognostic outcomes, better define the prognostic groups, and create substages that yield more appropriate surgical, radiation, and systemic therapies. The cancer committee developed a subcommittee on endometrial cancer staging in October 2021, of which the authors are members.
