Purpose: The aim of this study was to determine the actual human papillomavirus (HPV) subtype that presents in cervical dysplasia and invasive carcinoma in the Saudi population, and the feasibility of using Hybrid Capture 2 technique (HC2) on biopsy specimens to detect certain HPV subtypes.
Patients and methods: A prospective study was conducted from March 2007 to December 2008. The subjects studied were women with a mean age of 48.18 years, who attended the hospital for cervical biopsy due to the suspected diagnosis of cervical dysplasia or an invasive disease, based on previous suspicious Pap smear. HPV DNA hybridization by HC2 was performed on the cervical biopsies of these patients, to detect HPV infection.
Results: During the period of this study, 45 patients had cervical biopsies taken for HPV testing. Seven patients had a negative HC2 result and were found to have no cervical dysplasia on the final pathology review. Seventeen cases with cervical dysplasia and 21 patients with invasive disease were presented; the mean age was 48 years. HC2 testing for HPV were found to be positive in patients with cervical dysplasia, invasive carcinoma, and all in 5 (29.4%), 13 (61.9%) and 18 (47.4%), respectively. The sensitivity of the test is 47% and specificity is 100%.
Conclusion: The use of molecular detection of HPV DNA by HC2 in biopsy is feasible and effective. These results confirm the finding that HPV contributes to the etiology of cervical cancer in Muslim society.
