Department of Radiation Oncology

Since its inception in 1968, Saint Louis University’s Department of Radiation Oncology has been an integral part of our cancer treatment and academic medical practice. Radiation oncology works closely with SLUCare surgeons and other health care professionals to treat patients who have brain, head and neck tumors, as well as those with prostate, lung, breast and liver cancer.

The state-of-the-art Center for Radiation Medicine is located adjacent to the West Pavilion Cancer Center Outpatient Services. The Varian TrueBeam Linear Accelerator expanded our capabilities including techniques like respiratory gating, Rapid Arc, Calypso, Vision RT, and Cone-beam CT for faster and precise treatment.

In 2017, Saint Louis University has transitioned its Stereotactic Radiosurgery (SRS) for brain and Stereotactic Body Radiotherapy (SBRT) to the pinpoint accuracy of Varian TrueBeam. Our history of intra and extracranial stereotactic radiation started in 2004 with the CyberKnife and now the TrueBeam has grown to offer options of open face masks, continual optical surface monitoring, radiofrequency guidance and Cone Beam CT localization. These accurate TrueBeam treatments are non invasive, faster and gated to help the radiation avoid organs at risk and target the tumor.
