Radiation Oncology - Chairman's Page

Welcome to the Department of Radiation Oncology!

Chul S. Ha, M.D

Our Department of Radiation Oncology, UTHSCSA, is located at an NCI designated cancer center, Cancer Therapy and Research Center (CTRC).  With 8 vaults, 4 linear accelerators including Novalis Tx, soon-to-arrive state of the art Versa HD, and 2 high dose rate afterloaders, we are one of the largest and technically most advanced departments of radiation oncology in the U.S.A. More importantly, I am proud to tell you that we have nationally recognized experts in almost every category of cancers. Once a patient arrives in our department for consultation or treatment, he or she can be assured that all of the medical decisions will be made with one goal in mind: the best care for the patient.

There are many cancer specific tumor boards at the School of Medicine and CTRC where patient’s medical care recommendations are made in a multidisciplinary setting that includes surgeons, medical oncologists, radiation oncologists, diagnostic radiologists, pathologists and other support staff. Within our department, every patient’s treatment plan is reviewed at quality assurance conferences attended by all of the radiation oncology faculty members and clinical physicists to ensure peer reviewed quality control. Our department offers many clinical trials open through the national cooperative study groups such as NRG (NSABP, RTOG and GOG)  and SWOG (Southwest Oncology Group). With close collaboration with the Institute for Drug Development (IDD), one of the nation’s largest and foremost phase I cancer drug trial centers located within CTRC, our department also renders an array of newest treatments in developmental stage available to our patients.

In addition to the clinical excellence, our department takes great pride in our commitment to education and research. We offer clerkships to qualified 3rd and 4th year medical students from around the world. We have ACGME (Accreditation Council for Graduate Medical Education) accredited residency program with 6 residents.  We also offer medical physics residency and DMP (Doctorate in Medical Physics) programs.  The division of radiation biology is not only known for its strength in DNA repair research but also its translational research in radiation protector. The division of medical physics is known for tremendous research productivity and is at the cutting edge of new technology development.
Close collaboration among the basic science, physics and clinical faculty members is greatly fostered in our department to constantly pursue a better way to diagnose and treat cancer.
I feel truly blessed to be surrounded by everyone in the department who strives daily to achieve excellence and national leadership in all three missions of our department: patient care, research and education.

Please take time, explore our website and meet the people from every corner of our department who make this place so special. If you have any question or suggestion for our department, please feel free to write or call me at (210) 450-5566.

Thank you very much.
