Ralph R. Weichselbaum, MD

D.K. Ludwig Professor of Radiation and Cellular Oncology

Chairman, Department of Radiation and Cellular Oncology

Dr. Ralph Weichselbaum specializes in the treatment of potentially curative treatment of "oligo" metastasis with radiotherapy.

Dr. Weichselbaum's research interests include mechanisms of tumor spread and how radiation therapy and immunotherapy can be used to better treat cancer. He is also studying patterns of gene expression in human tumors that confer resistance to radiotherapy and chemotherapy. Weichselbaum invented a radio-inducible form of gene therapy TNFerade, which is currently in clinical trials. His research has been funded by the National Institutes of Health for more than 35 years.

He is also editor of Cancer Medicine, a definitive reference textbook compiled to help oncologists and internists apply scientific principles to clinical practice.

Read More About Dr. Weichselbaum

Dr. Weichselbaum and colleagues report that targeted radiation therapy can control cancer in select patients with cancer that has spread (metastatic disease) to only a few sites.

Dr. Weichselbaum's research team found that some patients with limited numbers of metastasis can be cured using stereotactic body radiotherapy.
