SWOG

[1] Comprising more than 4,000 cancer researchers at more than 650 institutions across the United States and Canada, it is one of the largest of the NCI's clinical trial cooperative groups.

SWOG is headquartered at the Oregon Health & Science University in Portland, with an operations office in San Antonio, Texas and a statistical center in Seattle, Washington.

SWOG was created by the NCI in 1956 as the Southwest Cancer Chemotherapy Study Group (SWCCSG) and was headquartered in Houston, Texas.

As mandated by the National Cancer Institute (NCI), every radiotherapy (RT) department participating in a SWOG study submits their data to QARC for review.

The center was founded in 1977 as a not-for-profit health care organization designed to provide quality assurance for CALGB studies.
