Active clinical trials for "Breast Carcinoma In Situ"

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.

This randomized phase II trial is studying 4-hydroxytamoxifen to see how well it works compared with tamoxifen citrate in treating women with newly diagnosed ductal breast carcinoma in situ. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. It is not yet known whether topical tamoxifen causes less damage to normal tissue than systemic tamoxifen in treating patients with ductal carcinoma in situ.

The purpose of this study is to determine whether it is feasible to give a combination of Metformin and omega-3 fatty acids for one year to women with a history of early stage breast cancer. We will also evaluate whether the metformin and omega-3 fatty acids combination causes changes in breast tissue, blood, and mammograms.

This clinical trial is being conducted to find out the effects (good and bad) of giving the full radiation treatment for breast cancer as a single dose of radiation during surgery for breast cancer. This single fraction intraoperative radiotherapy with electrons will study the toxicity, local control and cosmetic outcome.

This randomized pilot clinical trial studied whether the Oncotype DX gene expression "Recurrence Score" (RS) would be useful for helping make a decision about which type of pre-operative treatment, hormone therapy or chemotherapy would be a better for patients with hormone responsive cancers that were not suitable for breast conserving surgery. The RS is currently used to predict the risk of distant recurrence and the benefit of the addition of chemotherapy to hormonal therapy in the adjuvant setting.

This phase II clinical trial studies how well omega-3 fatty acid works in treating patients with stage I-III breast cancer. Studying samples of tissue and blood in the laboratory from breast cancer patients receiving omega-3 fatty acid may help doctors learn more about the effects of omega-3 fatty acid on tumor cells.

The goal of this study is to assess patient satisfaction after oncoplastic breast conserving surgery. With the help of a breast-questionnaire the patient satisfaction will be assessed before the surgery and 4 weeks, 6 months and 1 year after the operation. The main question it aims to answer are: Does breast conserving surgery improve quality of life. type of study: cohort study, observational OCBS = oncoplastic breast conserving surgery BCT = breast conserving therapy DCIS = ductal carcinoma in situ participant population/health conditions Patients with newly diagnosed breast cancer, that can be treated breast conserving the participants have to be at least 18 years old Participants will fill out a questionnaire pre surgery, 4 weeks, 6 months and 1 year after the surgery. The individual questionnaires will be compared.

By this non-randomized prospective study, it's evaluated the outcome of patients underwent BCS for DCIS at whom an established score system to address adjuvant therapies have been prospectively applied, according to the wideness of free margins. Between March 2000 and April 2006, 224 patients were enrolled and followed within the study.

This study gathers information to create a database to improve the ability to diagnose cancer, predict long term health of breast cancer patients, and help develop future treatment products. This study will provide a foundational platform for therapeutic development and intervention studies in the future and may for therapeutic development and intervention studies in the future, and may advance researchers understanding of the contribution gut bacteria to altered circulating estrogens in breast cancer survivors.

The purpose of this study is to determine whether a new surgical technique (radioguided seed localization) for localizing nonpalpable breast tumours is better than the standard technique (needle localization).
