Filter by:RATIONALE: Diagnostic procedures, such as multifunctional magnetic resonance imaging and CT scans, may help reduce normal tissue damage in patients undergoing radiation therapy for cancer. PURPOSE: This clinical trial is studying how well radiation therapy planning techniques work in reducing damage to normal tissue in women undergoing breast-conserving surgery for ductal breast carcinoma.
This randomized phase I/II trial studies the side effects and best dose of lapatinib ditosylate and to see how well it works in treating patients with ductal breast carcinoma in situ. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Hypotheses: 1. The addition of tumour bed boost after BCS in women with non-low risk DCIS reduces the risk of local recurrence (invasive or intraductal recurrence in the ipsilateral breast). 2. The risk of local recurrence in the shorter fractionation arm is not worse than that for the standard fractionation arm. 3. A molecular signature predictive of invasive recurrence of DCIS will be detectable and the molecular signature may eventually have clinical utility for therapy individualization. Overall Objectives: 1. To improve the outcome of women with non-low risk DCIS treated with breast conserving therapy. 2. To individualize treatment selection for women with DCIS to achieve long term disease control with minimal toxicity.
The subjects in this trial have been diagnosed as having a pre-cancerous disease of the breast called ductal carcinoma in situ (DCIS). This condition is associated with the development of breast cancer in up to 50% of cases. The subjects are being asked to participate in this research study. They are being offered voluntary admission to this study to test the effects of a new investigational drug called Fulvestrant (Faslodex). This drug is approved by the United States Food and Drug Administration (FDA) for the treatment of advanced breast cancer but has not been approved for the treatment of DCIS. However, the FDA has given permission for the drug to be tested in this study. The purpose of this study is to find out if Fulvestrant has any effect on the subject's precancerous changes by comparing samples taken before and after receiving Fulvestrant.
