Abstract

Background/aim: Human papillomaviruses have been established as a risk factor for invasive carcinoma of the uterine cervix. HPV E6/E7 oncogene expression has recently emerged as a promising biomarker to determine the risk for progression to high-grade cervical lesions. The aim of this study was to evaluate HPV mRNA and DNA detection in samples with abnormal cytology. Materials and methods: Cervical specimens were obtained at the Department of Obstetrics and Gynecology via cervical brushes during January-October 2011. Liquid-based cytology slides were evaluated according to the 2001 Bethesda System. Cytology specimens from a total of 81 women with abnormal cytology were included. Real-time PCR and NASBA assays were performed to detect HPV DNA and E6/E7 mRNA, respectively. Results: HPV DNA was identified in 73 samples (90.1%). HPV E6/E7 mRNA expression was observed in 45 samples (55.6%). A statistically significant difference was observed among cytological diagnosis groups. In 25 patients, a biopsy was performed during the follow-up. HPV DNA was detected in all of these patients. HPV E6/E7 expression was present only in CIN I-III diagnosed patients. Conclusion: The E6/E7 mRNA test is a robust indicator of cytological atypia and correlates better with progressive lesions than DNA assays.
