A Phase III Randomized Trial of Topical Vaginal Fluorouracil (5-Fluorouracil, 5-FU) Maintenance Therapy Versus Observation After Standard Treatment for High-Grade Cervical Dysplasia in HIV-Infected Women

To determine the efficacy and safety of intravaginal fluorouracil administered as prophylaxis in HIV-infected women who have received standard ablative therapy (surgery) for high-grade cervical dysplasia (pre-cancer of the cervix; cervical intraepithelial neoplasia). To correlate time to recurrence of cervical dysplasia with T-cell function. Women with HIV infection are at greater risk for cervical dysplasia. Because of the likelihood that untreated or recurrent cervical dysplasia may progress to invasive cancer, there is an urgent need to develop appropriate therapies. Women with HIV infection are at greater risk for cervical dysplasia. Because of the likelihood that untreated or recurrent cervical dysplasia may progress to invasive cancer, there is an urgent need to develop appropriate therapies. Patients are randomized to receive either intravaginal fluorouracil or no treatment (observation only). Fluorouracil cream is self-administered via applicator at biweekly intervals for 6 months. Patients are evaluated for recurrent cervical dysplasia by cytology and colposcopy with or without biopsy.
