Abstract

BACKGROUND:

No accurate estimates of cervical cancer incidence or mortality currently exist in Georgia. Nor are there any data on the population-based prevalence of high-risk (HR) human papillomavirus (HPV) infection, which, in the absence of good-quality screening, is known to correlate with cervical cancer incidence.

METHODS:

We obtained cervical cell specimens from 1309 women aged 18-59 years from the general population of Tbilisi, and also from 91 locally diagnosed invasive cervical cancers (ICC). DNA of 44 HPV types was tested for using a GP5+/6+-based PCR assay.

RESULTS:

In the general population (of whom 2% reported a previous Pap smear) HPV prevalence was 13.5% (95% CI: 11.6-15.9), being highest in women aged 25-34 years (18.7%) and falling to between 8.6% and 9.5% for all age groups above 34 years. HR HPV prevalence was 8.6% overall, being 6.8% and 38.9% among women with normal and abnormal cytology, respectively. HPV45 (1.6%) was the most common type in women with normal cytology, whereas HPV16 predominated among women with cervical abnormalities (including 7 of 10 histologically confirmed cervical intraepithelial neoplasia 2/3) and among ICC (57.6%). The next most common types in ICC in Georgia were HPV45 and 18 (13.2 and 11.0%, respectively).

CONCLUSIONS:

We report a relatively high burden of HPV infection in Tbilisi, Georgia. Improving cervical cancer prevention, through screening and/or HPV vaccination, is an important public health issue in Georgia, where 70% of ICC are theoretically preventable by HPV16/18 vaccines.
