The assocication between human papillomavirus infection (HPV) and cervical lesionhas been well established. for detection and typing human papilloma virus deoxyribonucleic acid in cervical tissues, Southern blot hybridzation and polymerase chain reaction are commonly regarded as reference standard methods. However it has the limitation includeing technical difficulty, safety, subjectivey in result interpretation. Recently the chemilnuminescent molecular hybridization assay method has been windely used and it has been known that it can detect less hybridization assay method has been windely used and it has been known that it can detect less then 1 pg of DNA in a 100n1 aliquot of a crude specimen. This study was perfomed to determine the usefulness of hybrid capture HPV DNA assay for detecting low-risk and high-risk human papillomaviruses in histologically confirmed normal, cervical intraepithelial lesion(CIN) and invasive squamous cell carcinoma of the cervix, and to compare the correlation among cervical cytology, hiopsy finding and HPVs infelction ,and to detirmine whether the additon of the hybrid capture test to cytologic studies would improve the ability to identify signifcant lesions. Cervical cytologic smears, hybrid capture HPVs DNA assay, and pucnh bhiopsies were performed on 78 women who have normal cervix(28cases),cervical intraepithelila lesion (24cases), and invasive squamous cell carcinoma(26cases). At first the probes for low-risk HPV(6,11,42,43,44) and the proves for high-risk HPV(16,18,31,33,35,45,51,52,56)were used and secondly retyping was done for HPV 16 abd 18 in high-risk HPV positive cases.the results obtained were as follows; 1. Low-risk HPVs infections were 14.3% and 8.3% in normal cervix and cervical intraepithelial lesion respectively. High-risk HPVs infection were 7.1%, 70.8% and 73.1% in normal cervix, cervical intraeithelial lesion and squamous cell carcinoma respecitively. These was highly significant corelation between positive high-risk HPVs test, cervical intraepithelial lesion and squamous cell carcinoma. 2. Positivities of low and high-risk human papillomaviruses in patients with negative cytologic result were 9.1% and 15.1% respectinvely. 3. In patients with high-risk human papillomaviruses infection, human papilloma viurs 16 and 18 types were detected in 47.4% and 13.2%, respectinvely, and both HPV 16 and 18 positive and negative detention were 15.7% 23.7% respectinvely. Among 12patinent of cervical intraepithelial neoplasia with high risk HPVs infection, HPV 16 was detected in 66.6% and HPV 18 in 16.7% Among 24 squamous cell carcinomas with high risk HPVs infection, HPV 16was detected in 41.7% and HPV 16 in 12.5% and both HPV and 18 in 25% 4. In patients without koilocytosis by cervical tytology, low and high-risk human papillomaviruses or both were positive in 30.7% 5. In patients with positive high-risk HPVs, sensitivitives of koilocytosis were 64% and 69% in histologic and cytologc diagnosis, and specificities and specifictites were 58.5% and 62% respectively. Above result suggest that detection for high-risk human papilloma viruses type by hybrid capture assay improves the management of cervical intraepithelial neoplasia and is more useful method over cervical cytology only.
