HPV RNA and DNA testing in Polish women screened for cervical cancer - A single oncological center study.

Abstract

OBJECTIVES:

To evaluate the incidence of HPV infection, and the frequency of the various genotypes, using mRNA and DNA testing; to assess their relationship with the cervical lesions and women's age in the Polish patients.

STUDY DESIGN:

A group of 1840 women, most of whom had abnormal cytology, from the Franciszek Łukaszczyk Oncology Centre in Bydgoszcz, Poland were screened for presence of at least one of 13 high risk HPV. Following that, 545 HPV DNA positive women were tested for HPV infection using HPV mRNA with the Nucleic Acid Sequence-Based Amplification Assay (NASBA) method.

RESULTS:

In our study group, 70.1% had DNA HPV positive results. Only 4% of the women had normal cytology. Among 545 HPV DNA positive patients, 36.3% had HPV mRNA positive tests. Moreover, 48% of the HPV mRNA positive patients were infected with HPV 16, followed by 18 (12.6%), 31 (10.1%), 33 (8.6%%), 45 (4.5%), and 16.2% of HPV mRNA positive women were infected with more than one HPV genotype. Furthermore, we found that in women under 30, HPV DNA positivity was higher than HPV mRNA positivity, supporting the hypothesis that younger women's infections are mostly temporary.

CONCLUSIONS:

The differences in HPV prevalence and genotype distribution observed in our study may have an impact on the efficacy of HPV vaccinations for cervical cancer and the development of screening programs, which should be examined further in future studies.
