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 Clinical Trials

  • Nipple Sparing Mastectomy Registry

    The Nipple Sparing Mastectomy Registry (NSMR) has been designed to facilitate compiling information on metrics utilized, techniques utilized, aesthetic outcomes, as well as oncologic outcomes of the Nipple Sparing Mastectomy. The registry will aim 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 is a non-randomized, multicenter, prospective registry based within the Society’s Mastery of Breast Surgery Program. Note: This registry is closed for new recruitment.
