Abstract
AIMS: To investigate the correlation of various diagnostic cytological features in SurePath liquid-based cell preparations with high-risk human papillomavirus (HPV) infection. METHODS: Case-control study. SurePath specimens from 510 cases that had been tested for HPV DNA by Hybrid Capture 2 assay were retrieved and re-examined for 10 cytological features. Distribution of these features in high- and low-risk HPV types was compared and risk statistics were estimated. Effects of cervicitis on the manifestation of HPV cytological changes were adjusted by means of logistic regression. RESULTS: Cytological features of nuclear hyperchromasia, multinucleation and atypical metaplastic cells were predominantly noted in high-risk HPV infection in the category of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion. The odds ratios of these three features were 6-12 times higher in high-risk than low-risk HPV infection. CONCLUSIONS: Some diagnostic cytological features can be used as markers in Pap smear screening for assessing the types of HPV infection.
