Alternate Title Phase II Randomized Study of Green Tea or Polyphenon E in Preventing Lung Cancer in Former Smokers With Chronic Obstructive Pulmonary Disease
Trial Description Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea or polyphenon E may prevent cancer from forming in former smokers with chronic obstructive pulmonary disease. This randomized phase II trial is studying how well green tea or polyphenon E work in preventing lung cancer in former smokers with chronic obstructive pulmonary disease. Eligibility criteria include the following:
Final eligibility for a clinical trial is determined by the health professionals conducting the trial. All patients will receive a placebo drink and a placebo capsule four times a day for 2 weeks. They will then be randomly assigned (have an equal chance of being placed) to one of three treatment groups. Patients in group one will receive green tea drinks and placebo capsules each day. Treatment may continue for up to 6 months. Patients in group two will receive placebo drinks and polyphenon E capsules each day. Treatment may continue for up to 6 months. Patients in group three will receive placebo drinks and placebo capsules each day. Treatment may continue for up to 6 months. Patients will undergo blood, urine, sputum, and tissue sample collection before beginning treatment and periodically for laboratory studies.
