Medical Leadership

Eric Horwitz, MD

Eric Horwitz
  • Chairman, Radiation Oncology
  • Gerald E Hanks Endowed Chair in Radiation Oncology

Since joining the staff in 1997, Horwitz's contributions include spearheading the clinical program as it grew exponentially in size and patient volumes. He developed advanced treatment programs using intensity-modulated radiation therapy (IMRT), image-guided radiation therapy and brachytherapy, including high-dose-rate (HDR) brachytherapy for prostate cancer. As a result, Fox Chase was the first in the northeastern United States to offer HDR implants to men with prostate cancer.

In addition, Horwitz integrated the use of an MRI treatment simulator into prostate cancer treatment planning for both permanent, low-dose prostate implants and external radiation therapy. Fox Chase was the first in the world to use MRI in radiation treatment planning. Horwitz currently oversees the department's third expansion in seven years which includes three new treatment facilities in the Cancer Research Pavilion being constructed on the Fox Chase campus.

Horwitz has published extensively in peer-reviewed journals and is a co-author of several chapters in various oncology texts. He has been invited to give numerous lectures and presentations at professional meetings in the United States and abroad. Horwitz has been named a top doctor by Castle Connolly's "American's Top Doctors" and is annually listed as one of Philadelphia magazine's "Top Docs." He serves on the editorial board of the journal Brachytherapy and is vice president of the American Brachytherapy Society. He is also active in the American Society of Therapeutic Radiology and Oncology.

Horwitz received his MD from Albany College in New York after earning his undergraduate degree at the University of Pennsylvania in Philadelphia. He completed both his internship and residency at William Beaumont Hospital in Royal Oak, Mich., where he was chief resident in radiation oncology. Horwitz joined Fox Chase in 1997. In 2003, he was promoted from associate member to member with tenure in Fox Chase's division of medical science.
