The technique of liquid-based cytology (LBC) is of increasing diagnostic value in non-gynecological cytology. The purpose of the present study was to validate modifications to stages of the LBC process and to assess the diagnostic usefulness of the LBC technique.
Between May 2021 and January 2022, a total of 484 samples were prepared from routine cytology tests carried out in the Department of Tumor Pathology of The Greater Poland Cancer Center. The material was obtained from fine-needle aspiration biopsies and fluid samples. One hundred cases were selected for the research described in the article. The slides were prepared using the Becton Dickinson Totalys SlidePrep device.
Based on the research, it was concluded that predominantly the LBC technique gives better results than a conventional smear because the background, which would otherwise make it difficult to assess preparations, was eliminated. Additionally, in LBC preparations the cellularity was increased, and the cells were arranged in a monolayer system, which improves the image quality. The introduction of modifications to the LBC method facilitated the process of sample preparation, without adversely affecting the quality of the obtained material.
