Brief Summary: RATIONALE Green tea extract contains ingredients that may inhibit the growth of actinic keratosis
PURPOSE Randomized phase II trial to determine the effectiveness of green tea extract in treating patients who have actinic keratosis
Detailed Description: OBJECTIVES I Determine the efficacy of the green tea extract epigallocatechin gallate Polyphenon E topical ointment in causing complete clinical and histopathologic regression in patients with actinic keratoses II Determine duration of treatment with Polyphenon E necessary to cause regression in these patients III Describe pathophysiologic and molecular alterations in actinic keratoses and sun damaged skin that are not present in skin that is not sun damaged in these patients IV Determine the effects of this treatment on biomarkers for skin cancer in these patients
OUTLINE This is a randomized double blind placebo controlled study One of the patients arms is randomized to receive topical epigallocatechin gallate Polyphenon E the other arm to receive a placebo Patients receive topical applications daily for 12 weeks or until resolution of all actinic keratoses within the treatment field
PROJECTED ACCRUAL A minimum of 60 patients will be accrued for this study over 10 months
