Prevention Study
Summary
Study start date: October 1, 1997
Actual date on which the first participant was enrolled.OBJECTIVES: I. Determine whether a carotenoid rich diet will cause a significant increase in the regression of disease in patients with grade I or II cervical intraepithelial dysplasia. II. Determine whether the regression of disease in this patient population is reflected in the modulation of intermediate biological markers (viral genome copy number of human papilloma virus (HPV) and HPV E6/E7 expression). OUTLINE: This is a randomized, controlled study. Patients are randomized to one of two treatment arms. Arm I: Patients receive dietary counseling and eat 5-10 servings of carotenoid rich fruit and vegetables each day for a year. Arm II: Patients receive no counseling and maintain their normal diet. Carotenoid levels, HPV status, progression of cervical dysplasia, and diet (by food frequency checklist and food diary) are monitored in both groups. PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study within 5 years.
