Aim Polycystic ovary syndrome ( PCOS ) is a significant risk factor for premenopausal endometrial cancer ( EC ) and/or atypical endometrial hyperplasia ( AEH ). The aim was to elucidate the clinical background and detailed menstrual history of EC and/or AEH in young women with PCOS . Methods From January 2001 to December 2013, women under 35 years of age who had been diagnosed with EC and/or AEH and who had been treated at Kumamoto University Hospital, Japan, were recruited. The patients’ clinical characteristics, clinical stages of EC and/or AEH , medication and operation methods, endocrine profiles, and menstrual history were assessed retrospectively. Results Of all the cases of EC and/or AEH , 25 (4.6%) were under 35 years of age. The mean age was 29.0 years and all the patients were nulligravida. The clinical stages of EC and/or AEH that were identified included: AEH (five cases), stage IA (18 cases), IB (one case), and IIIA (one case). Fourteen (56%) cases met the criteria for PCOS . Both the Body Mass Index and Homeostatic Model Assessment–insulin resistance were significantly higher in the patients with PCOS than in the patients without PCOS . Medroxyprogesterone acetate therapy was not effective for the patients with PCOS and they underwent a hysterectomy more often than the patients without PCOS . All the patients with PCOS exhibited irregular menstruation or amenorrhea, the mean duration of which was 13.1 years before PCOS and EC and/or AEH were diagnosed. Conclusion Although both the patients with and without PCOS had irregular menstruation, the patients with PCOS were less likely to have fertility‐sparing surgery than the patients without PCOS because they had more advanced disease or failed to respond to medroxyprogesterone acetate therapy.
