Endometrial polyp size and polyp hyperplasia

Objective: To assess the correlation between the size of endometrial polyps and the histopathologic diagnosis of hyperplasia or cancer. Methods: A retrospective study was conducted using databases of the outpatient clinic at Antonio Pedro University Hospital in Niteroi, Brazil, and of a private hysteroscopy service. The analysis included 1136 asymptomatic patients with an endometrial polyp identified on hysteroscopy, with pathologic examination, during the period 1999-2012. The polyp size, the patients' age, the indication for hysteroscopic examination, and the use of hormone medication were compared with the finding of hyperplasia in the pathologic examination. Results: Only polyp size showed statistical significance among the variables analyzed (P < 0.05). Endometrial polyps greater than 15 mm showed a hyperplasia rate of 14.8%, compared with 7.7% in the group with smaller polyps (P < 0.05). Conclusion: Endometrial polyps measuring more than 15 mm were associated with hyperplasia. (C) 2013 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.
