BACKGROUND: Invasive cervical cancer is caused by human papillomavirus (HPV).
OBJECTIVES: To describe the prevalence and genotype distribution of HPV types in women at risk for cervical neoplasia.
METHODS: Our study summarized HPV types detected in 6654 samples that were sent to the serology laboratory from cervical clinics in northern Israel between 2006-2014. The HPV test was performed during investigation of atypical squamous cells of undetermined significance (ASCUS) results on Pap tests or due to complaints suggestive of cervical neoplasia. HPV types were classified as high risk (HPV-HR) and low risk (HPV-LR).
RESULTS: Of the samples, 46.4% (3085/6654) were HPV-HR positive. Of women with cervical intraepithelial neoplasia 2-3 (CIN 2-3) or cancer, 292/318 (91.8%) and 137/145 (94.5%), respectively, were HPV-HR positive. HPV 16 and HPV 18 were detected in 11.8% of the total samples and in 48.2% and 64.9% of the women with CIN 2-3 and with cancer, respectively. HPV was negative in 8/145 (5.5%) and 26/318 (8.2%) of women with cervical cancer and CIN 2-3, respectively.
CONCLUSIONS: This study shows the prevalence of HPV types in women at risk for cervical neoplasia. The sensitivity of all HPV types for CIN 2-3 and cervical cancer was 91.8% and 94.5%, respectively; and of HPV-HR types, 89% and 92.4%, respectively. Triage of HPV-HR types should be considered in women with ASCUS because HPV-HR types were discovered in only 36.7%. The distribution of HPV types in our population is similar to that reported for other developed countries.
