Green Tea Extract in Preventing Cervical Cancer in Patients With Human Papillomavirus and Low-Grade Cervical Intraepithelial Neoplasia
A Phase II Trial of Polyphenon E for Cervical Cancer Prevention

RATIONALE: Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.

PURPOSE: This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.

OBJECTIVES:

Primary

  • Assess the effect of Polyphenon E(defined green tea catechin extract) in patients with human papillomavirus (HPV) expression and low-grade cervical intraepithelial neoplasia (CIN 1) in a pre- and post-treatment setting.

Secondary

  • Compare the toxicity of green tea extract vs placebo among patients with CIN 1.

Tertiary

  • Evaluate the utility of karyometry as an intermediate endpoint biomarker for cervical chemoprevention studies.

OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive Polyphenon E once daily (standardized to contain 800 mg of epigallocatechin gallate, a major green tea catechin) for 16 weeks in the absence of unacceptable toxicity.
  • Arm II: Patients receive oral placebo once daily for 16 weeks in the absence of unacceptable toxicity.

After completion of study treatment, patients are followed for 2 weeks.

PROJECTED ACCRUAL: A total of 176 patients will be accrued for this study.
