[Endometrial brush biopsy in monitoring endometrial cytology during hormone replacement therapy]

During the past few decades, a variety of diagnostic methods for endometrium direct sampling have been developed. One of these new techniques is endometrial brush biopsy (uterobrush). The principal aim of uterobrush is early detection of endometrial carcinomas and their precursors, but it may be also used to follow up the patients undergoing hormone replacement therapy (HRT). So far, there are only few clinical reports evaluating uterobrush as a technique useful in monitoring endometrial cytology during HRT. In this study the world literature on using brush biopsy to monitor endometrial condition of women receiving HRT has been reviewed.
