RSSearch Patient Registry

About the RSSearch® Patient Registry

The Radiosurgery Society hosts the RSSearch® Patient Registry, the longest established patient registry dedicated to SRS/SBRT managed by a professional society. In 2020, this multi-platform research and data sharing registry exceeded 31,000 cases and has become a critical resource for radiosurgical investigators world-wide in a wide range of specialties, as well as hospitals, teaching institutions and researchers engaged in the field.

Since RSSearch opened in 2005, the data has served as the foundation for peer-reviewed publications and research; improved quality of patient care; elevated medical decision making; provided access to novel treatments and approaches; and advanced the science of SRS/SBRT. Data mined from RSSearch also contributes to the industry-wide development of clinical and quality guidelines.

We welcome new centers to participate in the RSSearch Registry. All participating centers need to have a designated Principal Investigator who is an RSS member in good standing, must receive approval of the RSSearch Registry Protocol at a local IRB/Ethics Committee and execute Data Usage Agreement. For more information email us.

"The RSSearch Registry provides a comprehensive and flexible system where we can use existing data fields and also customize new ones specific to our study, which will facilitate the analysis of patients treated on MRIdian at various institutions across the globe. Through our contributions to the RSSearch Registry, we hope to demonstrate how MRIdian can achieve substantial clinical benefit for cancer patients."
