Abstract

Liquid-based cytology (LBC) presents several advantages when compared to the conventional smears, such as clean background, residual material for additional cytological preparations
or even for molecular tests to infectious agents identification, mainly HPV. Besides these advantages, LBC detects more lesions than the conventional smears, and also reduce the number of unsatisfactory samples and false negative cases. The goal of this work was to evaluate the cytologic findings of two different LBC methodologies, DNACITOLIQ ® (DIGENE-Brasil) and Autocyte system (Tripath, USA) concerning the adequacy of the samples and diagnosis performance, and compare these results to those reported by conventional smears daily routine analyzed at Adolfo Lutz Institute. A total of 509 samples of DNA- CITOLIQ ® and 398 Autocyte consecutive cases from women examined at Leonor Mendes de Barros Hospital in 2002 (INCODEV ICA-CT-2001-10013 project) were analyzed. From DNACITOLIQ® cases 0.6% were unsatisfactory, 89.3% were negative, 7,1% ASCUS/ AGUS, 2.0% LSIL, 0.8% HSIL and 0.2% squamous carcinoma. Regarding adequacy parameters 89% were satisfactory, 10.0% were limited by absence of glandular cells and 0.4 limited by other reasons. Autocyte system diagnosis were: 0.5% unsatisfactory, 88.2% negative, 3.0% ASCUS/AGUS, 6.8% LSIL and 1.5% HSIL. Conventional smears comprised 33,313 samples where 5.0% were unsatisfactory, 92.6%...
