BACKGROUND: The aim of this study was to investigate the prevalence of human papilloma virus (HPV) infection from Turkish women with normal and abnormal cytology.
METHODS: Our study population consisted of 1252 women with normal and abnormal cytology. In our clinic, cervical cancer screening was performed by liquid-based cytology testing (ThinPrep Pap Test). Reflex high-risk (HR) HPV testing (Cervista HPV HR and HPV 16/18) was performed in cases with abnormal cytology (n = 330). HR HPV testing was performed to 922 cases with normal cytology.
RESULTS: HR HPV was detected in 18.7% of negative for intraepithelial lesion or malignancy (NILM) samples, and in 79.7% of abnormal cytology cases. HPV types 16 and/or 18 were found in 18.6% and 35.3% of normal cytology cases and abnormal cytology cases, respectively. Of all 435 HR HPV-positive samples, HPV type 16 and/or 18 prevalence was significantly higher in cases with more severe cytological abnormalities.
CONCLUSIONS: The HPV prevalence among Turkish women with normal and abnormal cytology identified in this study largely concurs with those in other studies throughout the world. HPV types 16 and/or 18 were detected significantly in normal cytology cases in our study. We also found that, as has been previously demonstrated, certain HPV genotypes (16/18) are associated with more severe pathologies. However, larger epidemiological studies in different regions of Turkey are needed to evaluate the accurate prevalence of HPV infection throughout the country.
