Stereotactic Radiotherapy Added to Oncology Services

Ames, Iowa - Mary Greeley Medical Center introduced stereotactic radiotherapy (SRT), a specialized type of radiation therapy, to the list of services offered at the William R. Bliss Cancer Center's oncology treatment options in Ames. 

Board-certified radiation oncologist Joseph Rhoades, M.D., of the William R. Bliss Cancer Center describes the advantages of SRT, shown in clinical trials, as remarkable. "Survival doubled in those patients with less than four areas of metathesis," he said. "Whole radiation therapy can cause fatigue, nausea, and vomiting, this new focused, precise radiation has virtually no side effects."

Radiation therapy uses radiation to treat cancer by directing a radiation beam to the tumor inside the body in order to destroy it. SRT delivers a high dose of radiation to the tumor in a short period of time, decreasing treatment duration from weeks to days and minimizing side effects. Imaging equipment is used to pinpoint the precise location of the cancer cells and allows monitoring of the cancerous area and other organs while treatment occurs.

Mary Greeley Medical Center also plans to introduce brachytherapy, during which radioactive sources are left in place permanently or temporarily, in upcoming months.

Providing SRT, brachytherapy, and other cancer treatment options supports Mary Greeley Medical Center's mission to provide high quality, cost-effective health care services that advance the health of central Iowans through specialized care and personal touch.
