About

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).

Full 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.

Exclusion criteria

Pregnancy
Patients who have undergone prior excisional biopsy for DCIS.
Patients who are unable to undergo MRI due to claustrophobia or other reason.
Patients with ipsilateral treatment for DCIS or breast cancer within 12 months prior to entering this study.
Patients receiving any other chemotherapy or investigational agents.
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.
