Comparison of the diagnostic value of cervical cytology and HPV HR DNA testing for the diagnosis of low-grade and high-grade squamous intraepithelial lesions across different age groups
Abstract
Objectives: To assess the diagnostic value of cervical cytology and HPV HR DNA testing for the diagnosis of low grade and high-grade squamous intraepithelial lesions across different age groups.
Material and methods: The study included 1103 patients, age 25–70 years. All patients underwent in-depth diagnostic tests following either an abnormal Pap test result or a clinically suspicious cervical lesion. In all women the following examinations were performed: a molecular test detecting 14 high-risk types of HPV, a colposcopy examination, as well as directed-biopsy of the cervix. The studied population was subdivided into four age groups.
Results: It was observed that the percentage of high grade squamous intraepithelial lesions (HSIL) and cancers increased with women’s age. Sensitivity of both methods for detecting high-grade squamous intraepithelial lesions was highest for women aged 40–49 years. Sensitivity values of HPV testing was higher than that of cervical cytology among women under age 50.
Conclusions: Specificity of HPV testing increased significantly with age of women and was several fold higher across all age groups than the specificity of cervical cytology.
