Hiram A. Gay, MD is an Associate Professor in the Department of Radiation Oncology at Washington University School of Medicine. He earned his medical degree from the University of Puerto Rico in 2000 and completed his residency in radiation oncology at SUNY Upstate Medical University in 2005. Dr. Gay joined the Washington University faculty in 2009 from East Carolina University, The Brody School of Medicine. His clinical practice and academic interests include cancer of the genitourinary area (prostate, urologic, bladder and kidney) cancer and head and neck cancer. He serves as the Clinical Director of Radiation Oncology at the South County Siteman Cancer Center. Dr. Gay is interested in improving the quality of life of patients undergoing radiotherapy for head and neck cancer and genitourinary (prostate, bladder) cancer. This involves reducing the radiation dose and volume treated for head and neck cancer patients, especially for those with Human papillomavirus (HPV / p16 positive) tumors. He initiated the high dose rate brachytherapy (HDR) program for prostate cancer which has resulted in decreased side effects for patients. Dr. Gay has published on techniques to minimize the side effects of high doses per fraction used in stereotactic body radiation therapy (SBRT) and brachytherapy. He is an active collaborator with scientists both in the USA and overseas in these areas. He is an active participant in novel clinical trials and new technologies to help patients.
