RATIONALE: A diet rich in carotenoids may be an effective treatment for cervical dysplasia. PURPOSE: Randomized phase II trial to study the effectiveness of a carotenoid rich diet in treating patients with cervical dysplasia.

Condition Treatment or Intervention Phase
Cervical Cancer
 Behavior: Carotenoid-rich diet
Phase II

MedlinePlus related topics:  Cervical Cancer

Study Type: Interventional
Study Design: Prevention

Official Title: Phase II Prevention Study of a Carotenoid Rich Diet in Patients With Grade I or II Cervical Intraepithelial Dysplasia

Further Study Details: 

Study start: October 1997

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).

PROTOCOL 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.
