Researchers at Mayo Clinic are developing a Biobank of adult stem cell-rich breast organoids, a new research resource to facilitate normal and cancer stem cell research. Subjects in the Biobank will provide samples of excess breast tissue, complete a health questionnaire, and allow access to medical records now and in the future. The Biobank serves as a library for researchers; instead of having to look for volunteers for each new project, researchers can use samples from the Biobank as well as share information already collected.

This phase II trial studies how well anastrozole and letrozole after surgery work in treating patients with stage I-III breast cancer. Drugs, such as anastrozole and letrozole may stop the growth of tumor cells by decreasing the amount of estrogen made by the body. Giving anastrozole and letrozole after surgery may prevent breast cancer from coming back (recurrence).

RATIONALE: Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy together with trastuzumab and lapatinib after surgery may kill ...

A pragmatic randomized clinical trial of patients with locally advanced breast cancer randomized to either proton or photon therapy and followed longitudinally for cardiovascular morbidity and mortality, health-related quality of life, and cancer control outcomes. Quality of life is the outcome measure for the estimated primary completion date of November, 2020.

This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on ...

This randomized phase III trial studies how well hypofractionated radiation therapy works in preventing recurrence in patients with stage IIa-IIIa cancer who have undergone mastectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells that remain after surgery and have fewer side effects.

The purpose of this trial is to determine the patient's pathological response after hypofractionated radiotherapy to the whole breast based on a specimen after surgery. The analysis of tumor mutation may lead to a better understanding of the effect of radiotherapy in 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.

Each year, the number of breast cancer survivors who choose post-mastectomy breast reconstruction keeps rising. Among women who elect to pursue breast reconstruction, approximately 75% will choose prosthetic breast reconstruction. Implant-based breast reconstruction is frequently achieved in two-stages. The first stage consists of the placement of a tissue expander after mastectomy. This is followed by a period of weekly tissue expansions that can last several months. In the second stage, the tissue expander is removed in a surgical procedure and replaced with a permanent breast implant. Tissue expansion is a well-established breast reconstruction technique characterized by high success rates and ...

This randomized phase II/III trial studies how well standard of care therapy with stereotactic radiosurgery and/or surgery works and compares it to standard of care therapy alone in treating patients with breast cancer that has spread to one or two locations in the body (limited metastatic) that are previously untreated. Standard of care therapy comprising chemotherapy, hormonal therapy, biological therapy, and others may help stop the spread of tumor cells. Radiation therapy and/or surgery is usually only given with standard of care therapy to relieve pain; however, in patients with limited metastatic breast cancer, stereotactic radiosurgery, also known as stereotactic ...

The purpose of this study is to look at the effects cancer and melanoma have on the immune cells found in lymph nodes.

The investigators believe that the lessons learned from studies regarding 30-day and 90-day readmission are primarily due to failure of early symptom recognition, and medical error. Through the aid of remote monitoring and early symptom detection, the hypothesis for the current proposal is that interventions can be recommended in an earlier, remote fashion that may result in earlier post-surgical discharge, prevent decompensation, and prevent increased readmissions that have been associated with decreased LOS in other surgical populations.
