According to this source: A new study assigned 1,200 men to get hormones plus radiation or hormones alone. After seven years, 74 percent of men receiving both treatments were alive versus 66 percent of the others. Those on both treatments lived an average of six months longer than those given just hormones.
This prostate study has the potential to change care right away. About 20 percent of the nearly 200,000 men diagnosed with the disease each year in the United States are like those in the study — with cancer that has spread to the area around the prostate. "It is this group of patients in whom many of the deaths from p...rostate cancer occur," because the condition is usually incurable, said study leader Dr. Padraig Warde, a radiation expert from the University of Toronto's Princess Margaret Hospital.
