Radiation oncology opening new fields

Radiation oncology is the branch of cancer therapy that uses high energy x-rays, gamma rays, electrons or protons to destroy cancer cells. Radiation can be delivered with a curative intent or to ease symptoms, such as pain. Many times radiation is also used with chemotherapy or surgery in the case of malignant and non-malignant tumors.

In treating cancer, it can be given before, during or after chemotherapy, or preoperatively or postoperatively.

Delivering the highest possible dose of radiation to the tumor yet sparing nearby normal tissue is the goal of radiation oncologists at MCG. Drugs can also be given in conjunction with the radiation therapy to protect normal tissues during treatment and to allow for higher doses.

The Georgia Radiation Therapy Center is working on expanding clinical trials to include Phase I and II trials. Phase III trials are already offered.

A brief description of the radiation oncology group's current interests includes:

• Catherine Chang, MD, finds giving radiation treatments gratifying because she knows they can yield very important outcomes for her patients. Dr. Chang is also a member of the Multidisciplinary Breast Cancer Team.
• Chris Sheils, MD, says he and colleagues utilize all the tools available to get the best results for patients. He specializes in gynocologic oncology.
