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.
