Active clinical trials for "Carcinoma, Intraductal, Noninfiltrating"

The goal of this prospective cohort study is to evaluate the possibility of vacuum-assisted excisional biopsy (VAE) to completely remove the pathology in case of small lesions for Atypical Ductal Hyperplasia (ADH) and low-intermediate grade Ductal Carcinoma in Situ (DCIS).

Hypotheses: 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). The risk of local recurrence in the shorter fractionation arm is not worse than that for the standard fractionation arm. 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: To improve the outcome of women with non-low risk DCIS treated with breast conserving therapy. To individualize treatment selection for women with DCIS to achieve long term disease control with minimal toxicity.

This clinical trial assesses if the use of a three-dimensional imaging device called the Clarix Imaging Volumetric Specimen Imager (VSI) can help guide and assist surgeons in identifying and removing all positive margins while in the operating room (intraoperative imaging) for patients with breast cancer and breast ductal carcinoma in situ. Breast conservation surgery or lumpectomy is a standard of care (routine) procedure that removes the tumor and a rim of surrounding normal tissue (margins) while leaving as much normal breast tissue as possible. A margin that does not contain tumor cells is called a negative margin and tells the surgeon that the primary tumor has been removed. A positive margin contains tumor cells at or near the edge of the tissue removed. As part of standard of care, surgeons take two-dimensional x-ray images of the tissue that has been removed in the operating room to assess if there is any additional tissue that should be shaved (removed) to get a negative margin. After the surgery is over, the tissue is examined once again by a pathologist in a laboratory to determine if there are any small pieces of tumor left in the margin that were not visible during surgery. If residual tumor is detected in the margin, a reoperation may be required to remove additional tissue until the tumor has been completely removed from the margin. Diagnostic procedures, such as intraoperative volumetric specimen imaging may reduce the rate of reoperation of for patients who previously underwent lumpectomy.

This PMPF study is proposed to evaluate in real life the reoperation rates (ROR) of breast cancer and/or DCIS surgery when including the use of the HLS in the context of breast lumpectomy margin assessment.

This pilot trial studies how well a diabetes prevention program with or without hunger training works in helping to lower breast cancer risk in obese participants. A diabetes prevention program involves learning about and receiving materials on different strategies to encourage weight loss, and hunger training involves learning how to recognize hunger. It is not yet known whether adding hunger training to a diabetes prevention program helps participants control their weight that could reduce the risk of some cancers.

The goal of this trial is to see if active surveillance monitoring and hormonal therapy in patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast cancer, can be an effective management of the disease. Participants will be asked to receive standard of care hormonal therapy or an investigational treatment. Participants will be asked to return for evaluation with MRI at three months and six months. Depending on the evaluation participants will have the option to continue on the treatment. If the evaluation suggests surgery is recommended, the participant will discontinue the study treatment and will undergo surgery. In addition to the treatment and MRI evaluation, participants will be asked to provide blood sample to understand their immune status, provide saliva sample for genetic testing, provide the study with a portion of the tissue or slides generated from tissue removed during surgery performed as part of their standard of care.

To evaluate whether the combination of clinicopathological factors and the use of the Oncotype DX DCIS score can avoid radiation in women with low risk DCIS who have had breast conserving surgery (BCS)

This randomized phase III trial studies metformin hydrochloride to see how well it works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.

This is a pilot study to determine safety, efficacy, and potential risks of robot assisted nipple sparing mastectomy (RNSM), by utilizing the daVinci surgical system.

This randomized phase I trial studies the side effects and best dose of endoxifen hydrochloride in treating participants who are undergoing breast surgery. Endoxifen hydrochloride may treat or reduce the risk of breast cancer.
