Brief Summary: RATIONALE Estrogen can cause the growth of breast cancer cells Hormone therapy using tamoxifen or letrozole may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes

PURPOSE This clinical trial is studying how well tamoxifen or letrozole work in treating women with ductal carcinoma in situ
Detailed Description: OBJECTIVES

Determine the clinical response in women with estrogen receptor-positive ductal carcinoma in situ DCIS treated with neoadjuvant hormonal therapy comprising tamoxifen or letrozole by evaluating the maximal change in tumor diameter on mammography and MRI following treatment
Identify those cellular antigens which are altered by hormonal therapy
Determine which cellular antigens are predictive of clinical response to hormonal therapy
Evaluate whether genomic changes or gene expression in DCIS are altered by hormonal therapy and find candidate genes which are correlated with response to treatment

OUTLINE This is a pilot study

Patients who are premenopausal receive oral tamoxifen once daily for 3 months in the absence of unacceptable toxicity Patients who are post menopausal receive oral letrozole once daily for 3 months in the absence of unacceptable toxicity

After 3 months of hormonal therapy patients undergo lumpectomy or mastectomy

After completion of study treatment patients are followed every 6 months for 5 years and then annually thereafter

PROJECTED ACCRUAL A total of 40 patients will be accrued for this study
