Purpose
RATIONALE: Tretinoin may help cervical neoplasia cells develop into normal cervical cells. It is not yet known whether tretinoin is more effective than a placebo in preventing cervical cancer in patients with cervical neoplasia.
PURPOSE: Randomized clinical trial to study the effectiveness of tretinoin in preventing cervical neoplasia from developing into cervical cancer.

Drug: tretinoin |
| Study Type: | Interventional |
| Study Design: | Prevention, Randomized |
| Official Title: | Retinoids and Intermediate Biomarkers for CIN II and III: Pilot Trial |
| Estimated Enrollment: | 180 |
| Study Start Date: | January 1999 |
OBJECTIVES: I. Determine whether topical tretinoin reduces the number of viral genome copies of human papilloma virus (HPV) per cell and inhibits HPV E6/E7 gene expression in patients with cervical dysplasia. II. Determine the dose of tretinoin for use in a definitive trial that produces the best overall modulation of these biomarkers.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to cervical intraepithelial neoplasia classification (II vs III). Patients are randomized to 1 of 4 arms. Arm I: Patients receive low-dose tretinoin topically via cervical cap and polyurethane ether foam sponge changed daily for 4 days. Arm II: Patients receive intermediate-dose tretinoin as in arm I. Arm III: Patients receive high-dose tretinoin as in arm I. Arm IV: Patients receive placebo topically as in arm I therapy. Patients are followed for 6 months.
PROJECTED ACCRUAL: A total of 180 patients (45 per arm) will be accrued for this study.
