Clinical trials Below are current clinical trials.32 studies in Breast Clinic (open studies only). Filter this list of studies by location, status and more. Breast Cancer, Reasoning, And Activity Intervention Scottsdale/Phoenix, Ariz. This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer. Infection Outcomes Assessment of Absorbable Antibacterial Soft Tissue Support in Breast Reconstruction Rochester, Minn. The purpose of this study is to demonstrate the safety and effectiveness of the Melodi Absorbable Antibacterial Matrix for soft tissue support in immediate, two-stage postmastectomy alloplastic prepectoral breast reconstruction, to support an FDA Premarket Approval (PMA) Application. Understanding The Relationship Between Benign Breast Tissue, Benign Breast Disease, And Breast Cancer Development Jacksonville, Fla. The purpose of this study is to culture human mammary cells to identify cellular characteristics associated with lobular involution status. A Study to Evaluate the Patient Experience Regarding Image-Guided Percutaneous Breast Biopsy Jacksonville, Fla. The purpose of this study is to to better understand the concerns of patients prior to a breast biopsy so that we may improve our practice and ultimately enhance overall patient experience. Dose Escalation Study of mRNA-2752 for Intratumoral Injection to Participants in Advanced Malignancies Scottsdale/Phoenix, Ariz. The purpose of this study is to assess the safety and tolerability of escalating intratumoral doses of mRNA-2752 in participants with relapsed/refractory solid tumor malignancies or lymphoma. Turkey Tail Mushroom For Treating Post-Menopausal Women With HER2-Negative ER-Positive Breast Cancer Undergoing Surgery Scottsdale/Phoenix, Ariz. This phase II trial tests how well turkey tail mushroom (TTM) works in treating post-menopausal women with HER2-negative, estrogen receptor (ER)-positive breast cancer undergoing surgery. TTM is a common mushroom. In traditional Chinese medicine, it is used for enhancing function and removing toxins, as well as for cancer, hepatitis, and infections. There is previous evidence of significant tumor shrinkage occurring in the 2-month window between diagnosis and surgery in women who have taken TTM. Giving TTM may be effective in treating post-menopausal women with HER2-negative, ER-positive breast cancer undergoing surgery. A Vaccine (H2NVAC) Before Surgery For The Treatment Of HER2-Expressing Ductal Carcinoma In Situ Jacksonville, Fla., Rochester, Minn. This phase Ib trial studies the side effects and best dose of a vaccine called H2NVAC before surgery in treating patients with HER2 expressing ductal carcinoma in situ. H2NVAC is a vaccine designed to stimulate specialized white blood cells in hopes of increasing immune response and protecting against breast cancer. A Study of Women undergoing Mammogram Screening at Mountain Park Clinic Rochester, Minn., Scottsdale/Phoenix, Ariz. The goal of this research is to identify risk profiles of women (with particular emphasis on Hispanic women) for breast cancer based on family history, breast density and other factors known to impact risk such as age, weight, age at menarche, age at birth of first child, etc. A Study To Evaluate Immune-related Biomarkers For Pathological Response In Stage II-III HER2-positive Breast Cancer Scottsdale/Phoenix, Ariz., Jacksonville, Fla., Rochester, Minn. The purpose of this study is to evaluate invasive disease-free survival (iDFS) of multi-epitope HER2 vaccine vs. placebo in combination with ado-trastuzumab emtansine (TTT-DM1) in patients with stage II-III HER2+ breast cancer with residual disease post-neoadjuvant chemotherapy, and to evaluate the safety of multi-epitope HER2 vaccine given concurrently with T-DM1 maintenance therapy. A Registry For The Collection And Maintenance Of Biological Specimens For Breast Cancer Research Rochester, Minn. The purpose of this registry is to collect and maintain samples of breast tissue from women and men undergoing surgery for a breast related concern at Mayo Clinic Rochester, to create a biospecimen resource for the study of benign and cancerous breast conditions.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
