Mission, Vision and History


To prevent cancer in the community and transform cancer patient care through scientific discovery.


World leaders in cancer care – one patient at a time.

Our History

In 1999, the largest gift ever received by Barnes-Jewish Hospital and Washington University School of Medicine in support of cancer research, patient care and services and education and community outreach was made by Alvin J. and Ruth Siteman for the development of Siteman Cancer Center.

A few years later, in 2001, the National Cancer Institute designated Siteman as a Cancer Center, which signaled that the institution had demonstrated significant scope and quality in its cancer research programs. The NCI named Siteman a Comprehensive Cancer Center in 2005, renewing the designation in 2010 and 2015. In 2015, the NCI awarded Siteman an “exceptional” rating, based on a rigorous review of Siteman’s research programs. The grants resulting from Siteman’s designation as a Comprehensive Cancer Center, as well as shared scientific resources and seed awards, fund programs and specialized services that promote multidisciplinary research and new research opportunities.

Scientists and physicians affiliated with Siteman receive more than $150 million in research grants annually. The results of basic laboratory research are rapidly incorporated into treatment advances. This process is enhanced by patient access to 500 therapeutic clinical trials, including many collaborative efforts with other leading cancer centers throughout the country.

More than 450 Washington University physicians and scientists treat 50,000 cancer patients, including nearly 9,000 newly diagnosed patients each year at Siteman, making it one of the largest U.S. cancer centers.

Together, we’re making internationally recognized advances in cancer research, treatment and prevention – with an eye on treating one patient at a time.
