About Dr. Koay
Dr. Koay is an Associate Professor in the Department of Radiation Oncology at MD Anderson Cancer Center and serves as co-director of Gastrointestinal (GI) Radiation Oncology for the MD Anderson Cancer Network.
The MD Anderson GI Radiation Oncology Section represents decades of GI cancer expertise by nine radiation oncology doctors, and a specialized team of GI radiotherapy physician assistants, nurses, physicists, therapists, and dosimetrists. We treat cancers of the stomach, liver, bile duct, pancreas, rectum, and anus. We offer every type of radiotherapy technology including intensity modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), and proton therapy, always selected and personalized for each patient. We are constantly working to improve radiotherapy for GI cancers, and offer many clinical trials designed to make radiotherapy more effective with fewer side effects.
Dr. Koay treats all types of GI cancers. He is well-recognized for his clinical and translational research on GI cancers and their properties on diagnostic imaging, participating in national and international collaborations at the forefront of science. He has published over 60 articles, and a textbook titled An Introduction to Physical Oncology. He enjoys educating the next generation and has given lectures at multiple undergraduate, graduate, medical, health professional and resident courses. He has mentored dozens of students, residents, and fellows over the past decade, helping them achieve successful presentations, publications, and awards.
