OBJECTIVE: Our aim was to assess the validity of non-classical cytological signs in minimally abnormal cervical smears for the prediction of HPV infection. METHODS: 164 ThinPrep monolayers were re-screened for mild nuclear changes, disorders of keratinisation, abortive koilocytes and 'measles cells', as well as degenerative changes. HPV DNA was detected by GP5+/6+ and MY09/MY11 consensus primer PCR assays. RESULTS: Seventy six of 164 cases (46.3%) had HPV positivity by PCR. All cytomorphological features studied were significantly associated with the presence of HPV. Mild nuclear changes had 100% sensitivity and 100% negative predictive value for HPV infection. CONCLUSIONS: Our results indicate that non-classic cytomorphological signs can improve the sensitivity of cytology for detecting HPV. Minimally abnormal Pap smears lacking mild nuclear changes (16%) in the present study--do not require further molecular HPV testing.
