Shaped-beam radiation therapy is a promising treatment for life-threatening metastatic liver tumors, according to researchers at the University of Rochester Medical Center who report an 88 percent success rate for controlling the lesions. This is the first evidence that doctors can treat these tumors with radiation, and the results doubled the average length of survival.
"Radiation therapy has not been a recommended treatment for liver metastases because of the poor results when whole-liver radiation was used," said Alan Katz, M.D., M.P.H., lead researcher and assistant professor of Radiation Oncology. "High-dose, precision radiation therapy is proving to be a promising therapy for metastatic liver disease and provides an effective treatment option for patients who previously didnt have any."
Radiation oncologists at the Universitys James P. Wilmot Cancer Center are leading the effort to expand shaped-beam radiation therapy – originally designed to treat brain tumors – to target metastatic liver tumors with pinpoint accuracy. Initial treatment results were presented this week at the American Society for Therapeutic Radiology and Oncologys annual meeting in Denver.
