Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>We compared the cytoarchitectural features used for the cytologic diagnosis of endometrial adenocarcinoma (EC) using ThinPrep® (TPS = ThinPrep Sample) and BD SurePath™ (SPS = SurePath Sample) preparations. In 20 patients, a direct endometrial sample using the Uterobrush was obtained. Nineteen cases of EA and one case of carcinosarcoma were studied. TPS and SPS were performed according to the manufacturer's recommendations. Moreover, after the TPS preparation, the residual material was also used to prepare an SPS sample (TP–SPS = ThinPrep–Surepath sample). The following points were investigated in both preparations: (1) number of cell clumps; SPS had a significantly higher (20.9) than TPS (1.7) and TP–SPS (10.3); (2) long axis of clumps; SPS had a significantly higher (215.4) than TPS (146.0); (3) rate of cell clumps with longer axes than 200 μm; SPS had a significantly higher (36.7) than TPS (15.2) and TP–SPS (24.2). TP–SPS showed higher values than TPS; (4) nuclear area; TPS had a significant higher (61.2) than SPS (40.8) and TP–SPS (38.6); (5) degree of overlapping nuclei; SPS (3.4) had a significantly higher number of overlapping nuclei than TPS (0.7) and TP–SPS (2.1); (6) nuclear chromatin pattern; no significant differences for the nuclear chromatin pattern were found in the three different methods. The poor performance of TPS versus SPS and TP–SPS was explained with the heavy blood contamination of the samples, and the absence of adhesive coating in the slides is used for TPS. Further investigation of technical differences in liquid‐based cytology methodologies is needed. Diagn. Cytopathol. 2013;41:673–681. © 2013 Wiley Periodicals, Inc.</p> </abstract>
