Registries & Trials
To support its continuing efforts to enhance patient care, the Society strongly encourages its members to participate in research and clinical trials. The Society has served and will continue to serve as a sponsor/co-sponsor of registries/trials, when deemed appropriate. Links to information on additional registries and clinical trials, as well as resources designed to assist surgeons interested in participating in such efforts, are listed below.
Society-Sponsored Registries and Research Studies
Idiopathic Granulomatous Mastitis Registry
Status: Active & Recruiting
Background. Idiopathic granulomatous mastitis (IGM) is an uncommon inflammatory condition that requires specialized care. Etiology is unclear and medical and surgical management is complicated. There is a paucity of high-quality literature on its treatment. These patients often get discussed on the ASBRS Forums with mixed recommendations. It is a problem the membership has to treat without consensus on the best treatments. The purpose of this registry trial to be able to collect data on a large cohort of patients across multiple institutions to identify the most efficacious ways to treat this condition. Learn More.
Background. The COVID-19 pandemic rapidly altered health care worldwide. To save protective equipment and minimize exposures, hospitals stopped some or all cancer surgery, leading oncologic providers to quickly adjust patient management. The goal of this study was to describe the breast cancer patient level changes which occurred during the initial months of COVID-19 in the United States. View full publication:

Nipple Sparing Mastectomy Registry
Background. The Nipple Sparing Mastectomy Registry (NSMR) was designed to facilitate compiling information on metrics utilized, techniques utilized, aesthetic outcomes, as well as oncologic outcomes of the Nipple Sparing Mastectomy. The registry aimed to provide a large prospective collection of data points specifically gathered to provide evidence-based medicine on outcome measures and metrics utilized for the nipple sparing mastectomy. This was a non-randomized, multicenter, prospective registry based within the Society’s Mastery of Breast Surgery Program. The nipple sparing mastectomy registry successfully enrolled 2,000 patients and closed in May, 2021.
The CALLER Re-Excision Study
Background. More than 20% of patients undergoing initial breast-conserving surgery (BCS) for cancer require reoperation. To address this concern, the American Society of Breast Surgeons (ASBrS) endorsed 10 processes of care (tools) in 2015 to be considered by surgeons to de-escalate reoperations. In a planned follow-up, we sought to determine which tools were associated with fewer reoperations. View full publications:
