Abstract

OBJECTIVE:

To study the prevalence of low-risk and high-risk HPV genotypes in a largely suburban, non-Hispanic, white female population of the USA, and to determine the positive predictive value of one-occasion HPV detection and genotyping using high-grade squamous intraepithelial lesion (HSIL) cytology as the endpoint for clinical evaluation.

METHODS:

HPV DNA present in liquid-based cytology specimens collected by gynecologists in private practice was amplified using nested polymerase chain reaction. HPV DNA was validated by signature DNA sequencing for accurate genotyping.

RESULTS:

Of 2633 specimens, 278 were positive for HPV DNA of any genotype. Among 255 single HPV infections, the most prevalent genotype was HPV-16 (n=50; 19.6%), followed by HPV-52 (n=24; 9.4%). Only 10 specimens, all positive for a high-risk HPV, were associated with an HSIL cytology result. Among them were 6 of the 50 specimens (12%) tested positive for HPV-16. One novel HPV-39 variant was detected in repeat testing in a patient with persistent HPV infection.

CONCLUSION:

DNA sequencing is a useful method for increasing the specificity of HPV genotyping as an aid to follow persistent high-risk HPV infections to reduce excessive colposcopies in populations with low cancer prevalence.
