Maury Regional Hospital’s Cancer Center began utilizing a new technology—High Dose Rate (HDR) brachytherapy—in the Cancer Center, according to Dr. Michael Sattasiri, a radiation oncologist and medical director for the Cancer Center.

Brachytherapy attacks malignant tumors by placing a radioactive source within or adjacent to cancerous tissue. According to Sattasiri, this technology allows a physician to use a higher total dose of radiation to treat a smaller area in a shorter period of time than is possible with external radiation treatment.  Depending upon the type of cancer, brachytherapy may involve either the implanting of a permanent radioactive source—a seed—or in a temporary manner, in which a catheter is used to deliver radiation through a series of treatments over a short period of time.

According to Dr. Sattasiri, this new technology can be used to treat lung, esophageal, gynecologic, breast, cervical and endometrial tumors in the hospital’s Cancer Center. This new treatment has the ability to deliver a higher dose directly to the tumor while sparing healthy surrounding tissue.

“HDR will greatly improve the quality of care we can provide to our patients by allowing effective high dose treatments, given in a shorter treatment course, without increasing the risk of side effects,” said Dr. Sattasiri. “We are very pleased to offer this new technology, another service that expresses our dedication to win in the fight against cancer.”
