University of Pennsylvania doctor Gary D. Kao defended the quality of the brachytherapy radiation program he said he established and led at the hospital in a "field" hearing of the U.S. Senate Veterans Affairs Committee on Monday. In brachytherapy, physicians permanently implant in a prostate from 80 to 120 tiny metal "seeds" that emit radiation over a 10-month period. If improperly placed, the seeds can damage nearby organs while delivering less-than-optimal doses of radiation to the prostate.
A NRC medical expert "noted that the seed placement in the cases reviewed was quite erratic and not consistent with current medical standards." Ongoing investigations by the VA and the U.S. Nuclear Regulatory Commission, which oversees medical use of radioactive materials, found that 57 of the patients were under dosed. Another 35 patients got too much radiation to nearby tissues and organs, including 25 whose rectums received potentially dangerous doses.
