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 the 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 and renewed the designation again in 2010. The grants resulting from this designation, 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 hold more than $160 million in cancer research and related training grants. The results of basic laboratory research are rapidly incorporated into treatment advances. This process is enhanced by patient access to more than 240 therapeutic clinical studies, including many collaborative efforts with other leading cancer centers throughout the country.

In 2011, Siteman treated more than 8,500 newly diagnosed cancer patients and a year later was named a top 10 U.S. cancer center by U.S. News & World Report.

Every year Siteman Cancer Center makes internationally recognized advances in the fields of cancer research, treatment and prevention and continues to provide ongoing care to about 40,000 people every year, making it one of the largest cancer centers in the United States.
