A Pilot Study of Chemo-prevention of Green Tea in Women With Ductal Carcinoma in Situ

Phase 2

Terminated

Brief Summary: The purpose of this study is to find molecular signs (biomarkers) to better understand the role of green tea as an anti-cancer and anti-inflammation agent in women with newly-diagnosed ductal carcinoma in situ (DCIS).

Detailed Description: Many studies have shown that green tea may have anti-cancer and anti-inflammatory effects in cancer cells and animal models of breast cancer. Some studies have found that Asian women who drink many cups of green tea have lower rates of breast cancer. Green tea may have an effect on proliferative and inflammatory pathways. Women with ductal carcinoma in situ (DCIS) have been found to have inflammation in the breast tissue surrounding DCIS lesions. Inflammatory pathways are being studied for a possible link to cancer. This study is designed to evaluate changes in biomarkers of proliferation, inflammation, and angiogenesis in response to green tea intake.

Recruitment & Eligibility

Age >18 years.
ECOG performance status <2 (Karnofsky >60%)
Life expectancy of greater than 12 months.
Normal organ and marrow function as defined below:
leukocytes >3,000/mcL
absolute neutrophil count >1,500/mcL
platelets >100,000/mcL
total bilirubin within normal institutional limits
AST(SGOT) & ALT(SGPT)within normal institutional limits

Exclusion Criteria

Pregnancy
Patients who have undergone prior excisional biopsy for DCIS.

History of allergic reactions attributed to compounds of similar chemical or biologic composition to green tea extracts or sensitivity to green tea.
Uncontrolled concurrent illness including, but not limited to: ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
