RESUMO
OBJECTIVE: This study was performed to evaluate the clinical efficacy of high risk HPV DNA test using PCR for the detection of high-grade CIN or invasive cancer from patients with ASCUS or LSIL on Papanicolaou smear. METHODS: Sixty one patients with a Papanicolaou smear report of atypical squamous cells of undetermined significance or a low-grade squamous intraepithelial lesion underwent Cervical colposcopy and directed cervical biopsy and human papillomavirus test by PCR. We compared the detection rate of the high grade CIN and invasive cancer by Papanicolaou smear method only with that of both Papanicolaou smear and HPV PCR method. and we decided to be significant when P value was below 0.05 by SAS (v 6.02) program. RESULTS: The detection rate of high risk HPV DNA was 50.8% (31/61). The detection rate of high risk HPV DNA in high grade CIN and invasive cancer was 84.2% (16/19). Higher the grade of biopsy, more the detection rate of high risk HPV DNA. False negative rate which appeared high grade CIN or invasive cancer by biopsy was 31.2% (19/61) in Papanicolaou smear method only and 4.9% (3/61) in both Papanicolaou smear and HPV DNA method. CONCLUSION: We thought that additional HPV DNA test was useful to dectect behind high grade CIN or invasive cancer when the Papanicolaou smear result was ASCUS or LSIL.
