Clinical Trials

The purpose of this study is to learn whether there are differences in the outcome between placing the tissue expander above or below the chest muscle in women having immediate breast reconstruction following a mastectomy  The study will evaluate pain, wellbeing, and overall satisfaction with reconstruction. A secondary purpose is to learn whether there are differences in complications and costs between the two locations.

Plan to conduct a pilot randomized controlled trial to determine the feasibility, benefits and educational impact of using simulation for patient education (SimEd) for post-mastectomy wound and drain care, compared to current patient education practice (StdEd). This study also seeks to derive and validate a skills assessment tool specifically developed to evaluate skills acquired during the education process and compare the results of SimEd vs StdEd; we also plan to relate the scores of our assessment tool to a validated instrument that measures readiness for patient dismissal and compare their results in both study arms.

To determine the effectiveness of targeted nipple areola complex (NAC) re-innervation for improving sensibility in women undergoing nipple sparing mastectomy (NSM). 

This is a prospective, phase II trial to assess feasibility of patients undergoing NSM willingness to be randomized to neurotization or not. Feasibility is to be established in preparation for a larger, multi-site randomized prospective trial aimed at determining if neurotization improves objective and subjective patient outcomes. Patients undergoing NSM through an inframammary incision with prosthetic-based reconstruction will be randomized to undergo neurotization of the NAC (intervention) or not (control).

Feasibility will be defined as the accrual of 7 patients within a year (or 14 patients within 2 years).

Hypothesis: Patients undergoing NSM will be willing ...

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.

The purpose of this study is to evaluate surgical sterility, the microbiome, and infections post mastectomy with immediate/tissue expander surgery by using OR camera recording, surgical site and/or microbiome analysis.

The purpose of this study is to evaluate the timing of AVB-620 administration relative to surgery on the fluorescence and accuracy of the AVB-620 imaging data to distinguish between malignant and nonmalignant tissues in women undergoing surgery with primary, nonrecurrent and nonmetastatic breast cancer.

The purpose of this study is to assess outcomes, satisfaction and aesthetics of two different breast reconstruction techniques (Goldilocks alone, and Goldilocks with Implant-Based Reconstruction) and compare its safety, patient satisfaction, aesthetic evaluation and complications.

This study aims to evaluate the efficacy of personalized 3D-printed external breast prostheses for patients opting out of reconstruction and assess their satisfaction with a survey.

In the light of the pandemic, institutions have had to take greater precautions and instigate procedures to aim to improve safety and reduce risk for patients undergoing surgery. One intiative was designed to implement a same day discharge for patients undergoing mastectomy with or without alloplastic reconstruction. This study aims to evaluate the outcomes and patient satisfaction with same day mastectomy with or without alloplastic reconstruction following COVID-19 and compare satisfaction and outcomes (e.g complications) with patients pre-COVID 19. This is part of a quality improvement project. 

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.

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 compare and identify different forms/regimens of chemotherapy/hormone therapy in breast cancer patients who underwent mastectomy and subsequent immediate breast reconstruction (tissue expander or direct-to-implant). Subsequently, correlate these findings to assess overall surgical and clinical outcomes.

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."

The purpose of this trial is to determine the safety of 15 fraction vs 25 fraction pencil beam scanning proton radiotherapy after mastectomy in patients requiring regional nodal irradiation. Proton therapy is recognized as a standard option for the delivery of radiotherapy for breast cancer.

This study is being done to determine the long-term effects of different kinds of breast surgeries on women’s health-related quality of life from the patient’s perspective. The information will also provide information to assist in improving the quality of care given to patients.

The purpose of this study is to compare three different combination chemotherapy regimens and evaluate how well they work in treating women who have undergone surgery for node-positive breast cancer. Drugs used in chemotherapy, such as docetaxel, doxorubicin, cyclophosphamide, paclitaxel, and gemcitabine work in different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy after surgery may kill any remaining tumor cells.

This randomized phase III trial studies standard or comprehensive radiation therapy in treating patients with early-stage breast cancer who have undergone surgery. Radiation therapy uses high-energy x rays to kill tumor cells. It is not yet known whether comprehensive radiation therapy is more effective than standard radiation therapy in treating patients with breast cancer.

The purpose of this trilal is to study a combination of neoadjuvant radiotherapy (RT), immunotherapy (pembrolizumab) and chemotherapy for lymph node-positive, triple negative (TN) or hormone receptor positive/HER2-negative breast cancer.

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.

The primary purpose of this study is to identify the therapeutic effect of Adipose-Induced Regeneration (AIR) in radiation-induced skin injury of post-mastectomy breast cancer patients.
