Clinical Trials

This study will recruit breast cancer patients and survivors to take part in an ongoing study of the issues and concerns surrounding breast cancer survivorship. We will recruit both newly diagnosed patients as well as patients diagnosed within the past 5 years. Those who consent to the study will be asked to provide a series of questionnaires and blood samples over time. These data/samples will create a repository that will enable us to address many specific hypotheses both now and in the future. As part of the study DNA samples will be genotyped for common genetic variants ...

The purpose of this study is to develop a breast cancer survivor (BCS) multiscale omics database that includes a complete fecal metagenome (gut microbiome) and fecal metabolome characterization. 

The goal of this study is to further evaluate the effect of magnesium on the symptoms of menopause, specifically vasomotor symptoms (VMS) in breast cancer patients and/or women at an elevated risk of breast cancer.

This randomized phase III trial studies how well oxybutynin chloride works in managing hot flashes in patients who are not candidates for, or not interested in hormone replacement therapy. Previous studies have shown that oxybutynin is effective in managing hot flashes, however doses used in prior studies have resulted in side effects. This trial is evaluating lower doses of oxybutynin with the goal of determining if they are efficacious with less side effects.

The purpose of this study is to compare the effectiveness of fulvestrant to anastrozole or tamoxifen in treating invasive lobular breast cancer, by measuring the level of the biomarker Ki67 found in tumor tissue before and then after treatment.

The purpose of this research study is to test whether metformin, a drug commonly used to treat diabetes, is able to get rid of atypia (early cell changes that are thought to be a marker of breast cancer risk) in women at increased risk for breast cancer. There will be testing for the presence of atypia in the breast after metformin is given to see if it can get rid of atypia. The study will compare the effects, good and/or bad, of metformin or placebo on atypia to find out which is better. Note: The standard drug used for the ...

The purpose of this study is to determine if counseling patients about low dose tamoxifen will influence the decision to take (or not take) preventive therapy among women at increased risk for breast cancer.

The purpose of this study is to estimate the circulating tumor DNA (ctDNA)detection rate and mutational load in breast cancer patients with indications for regional nodal irradiation.

We aim to determine if Molecular Breast Imaging (a new nuclear medicine technique developed at Mayo) can identify malignant breast lesions in women who have atypical ductal hyperplasia, atypical lobular hyperplasia, or lobular carcinoma in situ.

The purpose of this study is to analyze breast tissue changes after a short course of Tamoxifen (Tam).

The purpose of this study is to compare the effectiveness of two different combinations of chemotherapy in treating women who have stage II or stage IIIA breast cancer that has spread to the lymph nodes. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which regimen of chemotherapy is more effective for breast cancer.
