Meet Dr. Hak Choy
Chair of the Department of Radiation Oncology

Holder of the:
The Nancy B. & Jake L. Hamon Distinguished Chair in Therapeutic Oncology Research

The expertise of Hak Choy, M.D., is in developing new drugs that will combine well with radiotherapy to improve outcomes for patients, particularly those with lung cancer.

At the end of the day, making a true impact on survival for the patient relies on how well we control cancer that we see (with radiation) and how well we control cancer that we don’t see (through chemotherapy), and how well both work in combination.”

Dr. Choy is Chair of the Department of Radiation Oncology and is known globally for his pioneering work, beginning in the early ’90s, showing the benefit of combining paclitaxel and other chemotherapeutic agents with radiation treatment.

More recently, advancements in technology have impacted day-to-day patient care, particularly for those with lung cancer. Dr. Choy has led the Department of Radiation Oncology at UT Southwestern to become, within a few short years, one of the leading institutions in the country housing all of these technologies, and he has instigated training programs to educate physicians on how to effectively use them in the clinic.

Dr. Choy continues to be active in designing national clinical trials that combine chemotherapy with the latest radiation treatment techniques. He holds numerous committee appointments within the Radiation Therapy Oncology Group (RTOG), the national clinical cooperative group for radiation therapy studies funded by the National Cancer Institute (NCI).
