ABSTRACT
INTRODUCTION: Within the Bethesda System, the recommendation of describing benign-appearing endometrial cells (BECs) has changed over recent years. Since the 2014 revision, their presence in cervical cytology reports has been deemed essential, beginning with age 45. Recent studies have suggested rising the reporting age to 50 years. Does the presence of these cells necessitate further assessment? MATERIALS AND METHODS: This retrospective cohort study included patients aged between 45 and 65 years in whom BECs were present on cervical cytology between January 2001 and December 2010, with a follow-up at 5 and 10 years. Women who had abnormal cervical cells or atypical endometrial cells on cervical cytology were excluded, as well as women with a history of cervical or endometrial cancer, or a history of hysterectomy and incomplete follow-up data. RESULTS: One hundred seventy-six women were included. Of these, 31% were postmenopausal of which 65% used hormonal substitution therapy. Twenty-eight percent presented with abnormal uterine bleeding at inclusion. During the follow-up period of 10 years, 87.5% had a normal gynecological follow-up and 11.4% underwent a hysterectomy for benign pathology. One percent (2 patients) had been diagnosed with endometrial malignancy, both presenting with postmenopausal bleeding and aged over 60 years. CONCLUSIONS: Our study confirmed that the presence of BECs is not a reason for concern when no additional clinical indicator is recognized, especially with normal ultrasonographic examination. Further invasive exploration may be controversial. If reporting BECs in cervical cytology continues, we strongly agree on rising the reporting age to 50 years or postmenopausal state.
