Effects of an Additional Liquid Based Cytology Prepate on Cytological Diagnosis in High-Risk HPV Positive, PaP Test Negative Cases

Özet

Objectives: To investigate the effects of a second cytology preparation on cytological diagnosis in high-risk HPV positive and PaPsmear-negative cases.Methods: This retrospective study was conducted with 57 cases who underwent cytological evaluation and cotest in our centerin 2016-2017. All of these cases were high-risk HPV positive, PaP smear-negative and had a second preparation. All preparationswere re-evaluated by a cytopathologist and a pathologist. Twenty-five of the cases who had a positive diagnosis in the secondpreparation had a cervical biopsy.Results: In 46 (80%) of the cases, the cytological diagnosis was the same and negative in the first and second preparations. Secondpreparations of 11 cases (19.2%) were positive. Twenty of 25 patients (77%) with cervical biopsy had premalignant lesion.Conclusion: In high-risk HPV positive and PaP smear-negative cases, patient management is different from cases where these twotests are positive together. According to our results, 19.2% of high-risk HPV positive and PaP smear-negative cases were given positive cytological diagnosis by second cytology preparation. Biopsy results support our cytological findings. The incidence of positive cytological diagnosis increases in PaP smear with the second preparation. With this protocol, patient management changes,follow-up time and number can be reduced.
