A study was undertaken to evaluate the utility of human papillomvirus (HPV) DNA screening and colposcopy in the management of women whose Papanicolaou smears demonstrated atypia less than dysplasia. Fifty patients whose initial Papanicolaou smears were interpreted as showing atypia less than dysplasia were evaluated for the dysplasia were evaluated for the presence of HPV 16 DNA in exfoliated cervicovaginal cells and for histologic findings on biopsy. Those 50 patients were compared to two groups of patients: one consisting of 124 patients with biopsy-documented cervical intraepithelial neoplasia (CIN) and another 112 patients with normal Papanicolaou smears. The presence of HPV 16 DNA was confirmed with Southern analysis in 46% of patients with atypical Papanicolaou smears, 46% with confirmed CIN and 11.6% with normal Papanicolaou smears. The 50 patients with atypical smears underwent colposcopically directed cervical biopsies, revealing the following results: 14 (28%) had normal histology, 29 (58%) had koilocytosis without dysplasia, and 7 (14%) had CIN. HPV 16 DNA was present in exfoliated cervicovaginal cells from a large percentage of patients from each category (50% of patients with normal histology 41.2% with koilocytosis and 57% with CIN). HPV 16 DNA screening did not predict which patients with atypical smears had underlying CIN. Colposcopically directed biopsy remains the evaluation method of choice.
