RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of diindolylmethane, a substance found in cruciferous vegetables, may keep cervical intraepithelial neoplasia or cervical cancer from forming.
PURPOSE: This randomized phase III trial is studying diindolylmethane to see how well it works compared to a placebo in treating patients with abnormal cervical cells.

Phase III |
Study Type: | Interventional |
Study Design: | Prevention, Randomized, Double-Blind, Placebo Control |
Official Title: | An Investigation Into the Effects of Diidolylmethane (BioResponse DIM®) Supplementation in Women With Low-Grade Cervical Cytological Abnormalities [CRISP-1] |
Estimated Enrollment: | 3000 |
Study Start Date: | October 2004 |
Estimated Primary Completion Date: | June 2008 (Final data collection date for primary outcome measure) |
OBJECTIVES:
OUTLINE: This is a double-blind, randomized, placebo-controlled, multicenter study. Patients are randomized to 1 of 2 treatment arms.
Patients complete a questionnaire at baseline (i.e., for reproductive history, diet, smoking, and premenstrual symptoms) and at 6 months (i.e., for side effects, compliance, changes in smoking, and contraception use). Patients with moderate to severe premenstrual syndrome (PMS) also complete PMS questionnaires once monthly during months 1-6 and 4 months following completion of study therapy. All patients are instructed to maintain current diet and to keep cruciferous vegetables and soy products constant during study course.
After completion of study treatment, patients are followed periodically for up to 7 years.
PROJECTED ACCRUAL: A total of 3,000 patients will be accrued for this study.
