Liquid-based endometrial cytology: the Florence and Bari experience.

Several diagnostic procedures are available to investigate the endometrium, i.e. sonography, hysteroscopy, biopsy, endometrial curettage and cytology. Among these, endometrial cytology is less commonly utilized. Although the use of cytology in the diagnosis of endometrial adenocarcinoma has already been proposed due to its low cost and simple execution, a general consensus has not been reached. The improvement of the diagnostic capacity of endometrial cytology following the introduction of a liquid-based method suggests that this test should be routinely used in endometrial diagnosis. The main advantages of this method are the reduction in confounding factors, the distribution of cells on a thin layer and the possibility to obtain more slides from the same sample. The aim of this article is to focus on the methodological procedures and diagnostic criteria in liquid-based endometrial cytology based on the experience in two Italian centres: Department of Pathology, University of Bari and Department of Human Pathology and Oncology, University of Florence. The sampling method used by the Bari authors consists in the collection of liquid for uterine distension during hysteroscopy, while the Florence group used an endometrial brush. The sensitivity and specificity at Bari were 75% and 83%, respectively, and were 94-100% and 95-100% at Florence, respectively. Endometrial cytology provided sufficient diagnostic material significantly more often than biopsy. We thus propose that endometrial cytology can be used in routine diagnosis either alone or in association with other diagnostic procedures in order to improve diagnostic accuracy.
