Significance: More than 70 types of HPV have been identified, and are generally classified as high-risk or low-risk depending on their known association or lack of association with cancer and its precursor lesion, high-grade cervical intraepithelial neoplasia (CIN 2-3). Prospective studies (age 16-60 years) have shown that 15-28% of HPV DNA positive women developed squamous intraepithelial lesions (SIL) suggestive of CIN 1-3 or cancer within 2 years compared to only 1-3% of HPV DNA negative women. Although current scientific literature suggests that persistent infection with high-risk HPV is the main risk factor for development of high-grade cervical neoplasia and cancer, apparent persistence may represent continuous infection with a single HPV type, with multiple HPV types, or reinfection. Nonetheless, women who are repeatedly Pap negative and HR HPV negative appear to be at low risk for having or developing cervical precancerous lesions.
