Radiation Therapy for Gastrointestinal Cancer

Radiotherapy is used in the treatment of many gastrointestinal cancers. For anal cancer in particular, it is often the main form of therapy, in combination with chemotherapy.

UT Southwestern physicians are world leaders in the development of a newer form of radiation delivery called stereotactic ablative radiotherapy (SABR, also known as SBRT). We have successfully tested a high-dose, single-treatment SABR procedure for liver cancer, demonstrating its safety and efficacy. With SABR treatment, the radiation beam is delivered from many different angles, sparing healthy tissue from excessive radiation while delivering a highly potent dose to the tumor target.
