The $13.1 million project will expand the existing facility from 19,500 square feet to 30,750 square feet. The groundbreaking is scheduled for October, with completion planned for November 2016.

The growth is in addition to expansion projects already underway at Siteman’s main campus at Washington University Medical Center and at Siteman Cancer Center-South County, near Interstate 55 and Butler Hill Road. Siteman also has a site at Barnes-Jewish West County Hospital in Creve Coeur. As part of the projects, additional physicians and health-care staff will be added to serve the growing number of patients seeking specialized cancer care at Siteman.

Timothy Eberlein, MD, Siteman’s director and head of the Department of Surgery at Washington University School of Medicine in St. Louis, said the expansion in St. Charles County demonstrates the commitment of Siteman and its partners – Barnes-Jewish St. Peters Hospital, Barnes-Jewish Hospital and the School of Medicine – to the health of patients in Missouri and beyond.​​​​​​​​​​​​

“As one of the largest cancer care providers in the nation, Siteman Cancer Center offers the most advanced care possible,” said Eberlein, who also is the Bixby Professor of Surgery and the Spencer T. and Ann W. Olin Distinguished Professor at the School of Medicine. “Our patients deserve the best, and with additional physicians and space, we can continue providing exceptional care closer to where they live.”

Washington University physicians at Siteman’s four locations treat 43,000 people each year, including 9,000 newly diagnosed patients. The cancer center recently received an “exceptional” rating – the highest possible – from the National Cancer Institute (NCI), the principal federal institute for cancer research funding. The rating is based on a rigorous review of Siteman’s research programs.

Expansion of the St. Peters facility, which opened in 2005, will allow:

  • ​Six medical oncologists to serve patients, up from three
  • Two radiation oncologists to treat patients, up from one full-time and one part-time radiation oncologist
  • An increase in exam rooms to 20, from eight
  • An increase in chemotherapy infusion chairs to 32, from 11

“Our mission is to improve the health of the people and communities we serve,” said Larry Tracy, president of Barnes-Jewish St. Peters Hospital. “In addition to providing excellent care, we want to ensure our patients’ comfort. That’s why the design process also focused on maintaining the friendly, community hospital atmosphere they appreciate.”

To allow for uninterrupted service during construction, Siteman-St. Peters will use the adjoining outpatient surgery center and medical office space. Barnes-Jewish St. Peters Hospital, part of BJC HealthCare, is contributing $10.6 million of the $13.1 million to the Siteman-St. Peters expansion. Washington University School of Medicine is providing the additional funds.

Highlights of the other two Siteman projects are below.

Five floors of a new, 12-story inpatient tower at South Kingshighway Boulevard and Forest Park Avenue will allow Siteman to consolidate and expand clinical care at its main location and provide space for other surgical services and programs. The 558,000-square-foot high rise also will consolidate obstetrics and gynecological services at Barnes-Jewish Hospital.

The project, which is expected to be completed by mid-2017, includes:

  • ​An increase in the number of inpatient cancer beds to 160, from 128, all in private rooms
  • A 25-bed intensive care unit, including 10 beds for bone marrow transplant patients
  • 12 new operating rooms, primarily serving colorectal, urology and gynecological cancer patients
  • A sixth-floor rooftop garden for cancer patients and families, with spaces for large and small gatherings

The center will grow to 41,463 square feet, from 36,761 square feet, when completed this October.

The expansion will increase:

  • ​Medical oncologists to 17, from 12
  • Exam rooms to 22, from 16
  • Chemotherapy infusion stations to 44, from 32

A second linear accelerator, which creates high-energy radiation to treat cancer, will be added at the location.
