Radiation Oncology

Radiation Oncology Clinical Research

Physicians and researchers associated with the Froedtert & Medical College of Wisconsin Clinical Cancer Center are members of several research groups that offer cancer trials sponsored by the National Cancer Institute (NCI). Our researchers also participate in university consortiums as well as develop and manage trials funded with grants from the Medical College of Wisconsin and other sources. Because of this, the Froedtert and Medical College of Wisconsin Clinical Cancer Center can offer the latest in treatment options that often are not yet available outside the research setting. Our interdisciplinary approach to cancer care and cancer research is evident by the strong relationship between radiology, surgical oncology, medical oncology, and radiation oncology.

The Department of Radiation Oncology is a leader in the NRG Oncology group, previously Radiation Therapy Oncology Group. (RTOG). NRG Oncology is part of the National Clinical Trials Network (NCTN). The NCTN is a collection of organizations and clinicians that coordinate and support cancer clinical trials across the United States and Canada. Our department has been a full member institution since 1979. We are the lead department in the VA research program and has consistently been one of the highest enrollers to NRG/RTOG studies with recognition for excellence in data quality. Many of our faculty have leadership roles in facets of NRG while pursuing individual research quests to prevent and treat cancer as well as minimize effects of cancer therapies on normal tissue.

In 2012, the Department of Radiation Oncology became a founding member of the Elekta MR-Linac Consortium. This consortium was formed to bring integrated magnetic resonance (MR) imaging and radiation therapy delivery into the clinic. The department has been extensively involved in developing and optimizing elements of the technology and clinical trials to demonstrate the effectiveness of MR-guided RT, particularly, in the areas of developing plan adaptation strategies, optimizing MR imaging techniques, designing innovative adaptive radiation therapy treatments for pancreatic cancer. The Chair of the department, Dr. Schultz, is the current Chair of the consortium.

For more information on clinical trials offered through the Froedtert and Medical College Clinical Cancer Center, call (414) 805-3666 or (800) 272-3666.

Translational/Basic Research Program

Translational research takes basic research from the laboratory for implementation into the clinical setting, often being described as "bench to bedside" research. Researchers in the Department of Radiation Oncology are involved in several translational and basic research programs in the following areas:

Radiation Biology

  • Low dose rate irradiation
  • Radiation damage to normal tissues

Molecular Biology

  • Biomarkers for radiation responses

Radiation Physics

  • Adaptive Radiation Therapy (online and offline)
  • Outcome modeling for treatment planning
  • Motion management
  • Anatomic/biological/functional imaging (CT, CBCT, MRI, PET) for treatment planning and delivery
