title: Outcome in mild and moderate cervical dysplasias related to the presence of specific human papillomavirus types.
abstract: In situ hybridization with biotinylated DNA viral probes (ISH-B) for human papillomavirus (HPV) types 6/11, 16, 18, 31, and 33 was used to study the outcome in 32 cases of mild and 21 cases of moderate cervical dysplasia with koilocytotic change that were followed for an average of 27 mo. The rates of regression, persistence, and progression for cervical intraepithelial neoplasia (CIN) I and CIN II were 50%, 41%, and 9%, and 43%, 48%, and 9%, respectively. While progression of HPV 16 CIN I and II lesions was observed, regression occurred in 80% (four of five) and 43% (three of seven) of CIN I and II HPV 16-positive lesions, respectively. Regression was also seen in lesions that contained HPV 31 or HPV 33. All of the HPV 18 lesions persisted. The findings are compared with those of previous studies. Since some of the assumed more aggressive viral types can regress when followed by cytologic and biopsy examinations, caution must be exercised when attempting to predict the clinical outcome based solely on the specific viral type present in a given CIN lesion.
