Imaging and Radiation Oncology Core

The Imaging and Radiation Oncology Core (IROC) is a center for the evaluation of data produced by clinical trials funded by the National Cancer Institute, as part of the National Clinical Trials Network "to provide integrated radiation oncology and diagnostic imaging quality control programs... thereby assuring high quality data for clinical trials designed to improve the clinical outcomes for cancer patients worldwide."

History
The history of the Rhode Island Center (previously known as QARC) goes back to the late 1970s when Rhode Island Hospital was conducting RT QA reviews of leukemia-based protocols for the CALGB, which is one of the major NCI-sponsored cooperative groups. Other cooperative groups like the Pediatric Oncology Group and the Children's Cancer Study Group decided to use the center's quality control. QARC began to seek funding from the NCI in order to manage the large influx of data, and received its first grant in 1980. Sixteen years later, in 1996, QARC switched its affiliation from Brown Medical School to the University of Massachusetts Medical School (UMMS). By late 2003, it moved from the Roger Williams Medical Center to offices in Federal Hill, Providence, Rhode Island; in August 2010, it relocated to its current site in Lincoln, Rhode Island.
