Abstract
OBJECTIVE: Endometrial cancer (EC) is the most common gynecologic malignancy with known risk factors including excess estrogen and hereditary syndromes. The objective of this study was to determine the proportion of young women with EC that could be attributed to these factors and if, as we suspected, there is a third population of young women in which neither factor is identifiable. We were interested in comparing clinicopathologic characteristics and outcomes across subgroups in order to better inform treatment recommendations. METHODS: We performed a retrospective chart review of women age 15-49 diagnosed with EC or complex atypical hyperplasia. Demographic, clinicopathologic, treatment, fertility, and outcome parameters were analyzed. RESULTS: Of 719 women identified, 327 were fully evaluable. 57.5% fit the "High Estrogen" risk criteria. 8.25% met criteria for suspected Lynch syndrome. 34.25% classified as "Neither" had no classical risk factors identified. There were no statistical differences in age, gravidity, tumor grade, treatment selection and response to hormonal therapy. Age of menarche, stage, histology, and synchronous ovarian cancer differed significantly. Prevalence of synchronous ovarian cancer was 21.0% of "Neither", 23.1% of "Lynch", and 6.6% of "High Estrogen". For women who attempted pregnancy, 2/27 of "High Estrogen", 0/3 of "Lynch", and 2/16 of "Neither" achieved a live birth. CONCLUSIONS: This study confirmed that a third population of young women with EC exist that lack classical risk factors and have distinct clinicopathologic parameters. No difference in success of conservative treatment or live births was noted in the small cohort in whom this treatment approach was attempted.
