Abstract:
Human papillomavirus(HPV) has implicated in the development of cervical cancer. Several studies has suggested a strong correlation between HPV 16, 18 and cervical intraepithelial neoplasia(CIN). For detecting and typing HPV DNA in cervical tissues, recently the chemiluminescent molecular hybridization assay method has been widely used. This study was performed to determine the usefulness of hybrid capture assay for detecting high-risk HPV in cervical epithelial cells, and to compare the correlation among cervical cytology, biopsy finding and HPV infection, and to determine whether the addition of the hybrid capture assay to cytologic test would improve the ability to identify significant lesions. This study included 267 patients who visited the colposcopic clinic of the department of obstetrics and gynecology, Chonbuk University Hospital from May, 1997 to October 199S. Pap smears hybrid capture assays, and colposcopically directed biopsy were performed concurrently on al1 women. The results obtained were as follow; l. Using hybrid capture assay, the detection rate of high-risk HPV of all patients was 37.1%(99/267). There was no statistical significance in the detection rate of HPV between the age groups. 2. The false negative rate of Pap Smear was 53.3% and showed significant discrepancies between the cytologic and histologic diagnosis. 3. According to the cytologic diagnosis, the detection rates of high-risk HPV were 7.1% in normal, 25.3% in ASCUS or LSIL, and 61.6% in HSIL. In each cytologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 4. According to the histologic diagnosis, the detection rates of high-risk HPV were 0.1% in normal, 11.1% in CIN I, and 72.7% in CIN II or CIN III. In each histologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 5. According to the comparison of histologic diagnosis between positive and negative results of high-risk HPV test due to each cytology, there was no statistical significance in the incidence rate of cervical neoplasia, Above results suggest that high-risk HPV test using hybrid capture assay may be a useful method in supplement the pitfalls of cervical cytology. This test might also have prognostic value in the management of patients with CIN.
