The study is relatively small and requires further confirmation, said Dr. Durado Brooks, director of prostate and colorectal cancer at the American Cancer Society.
"But for men trying to make a decision about prostate cancer treatment, it provides useful information for the men and their physicians," Brooks said. "A man who has had radiation treatment, if he and his doctor talk about the results of this study, it can help them make a decision about hormone treatment in a more informed way."
The results apply to "a significant percentage of older prostate cancer patients," Brooks said, noting that the average age of men in the study was over 70.
Until now, only general advice about hormone treatment could be given to such men, he said. "Now we can be a little more specific and say, 'If you don't have underlying cardiac disease or other major co-morbid conditions, the chance of having a good response to the treatment is better.' But many men with heart disease or other problems may decide they do not want to deal with the side effects of hormone treatment."
