Abstract

Abstract: Aim: We aimed to determine the frequency of endometrial cancer in infertile women undergoing hysteroscopic endometrial polypectomy for endometrial polyps. Methods: A total of 1035 infertile patients who underwent office‐based hysteroscopic polypectomy at Sugiyama Clinic Marunouchi between July 2011 and October 2015 were eligible for this retrospective study. All patients had been diagnosed with endometrial polyps via hysterofiberscopy prior to operation, and they underwent hysteroscopic endometrial polypectomy using a resectoscope with monopolar resection. Surgical specimens were examined histopathologically. Characteristics of patients diagnosed with endometrial cancer on histopathological examination were evaluated retrospectively. Results: The median age of patients was 32 years (range, 19–44 years). On histopathological examination, endometrial cancer was found in 10 patients (0.97%). Each histological type of endometrial cancer was represented as follows: three cases of endometrioid adenocarcinoma G1; one of endometrioid adenocarcinoma G2; two of endometrioid adenocarcinoma G3; and four of atypical endometrial hyperplasia. The median age of endometrial cancer patients was 34 years (range, 28–41 years), and the median body mass index was 21.2 kg/m 2 (range, 16.7–29.9 kg/m 2 ). Nine endometrial cancer patients were nulliparous, and all had undergone infertility treatment, with only one woman having delivered a healthy baby. An ovulation disorder was noted in four patients, with obesity (body mass index > 25 kg/m 2 ) in just two. Polycystic ovary syndrome was concomitantly observed in one patient. However, abnormal vaginal bleeding was not noted in any of these patients. Conclusion: Hysteroscopic polypectomy should be performed when endometrial polyps are detected on investigational screening, and surgical specimens should be checked for the presence of malignancy.
