Study Sees No Benefit in Prostate Surgery

A new study of men with early prostate cancer found no difference in death rates whether they received surgery or no treatment. The study adds to recent evidence that prostate cancer may be overtreated in the United States. The study included 731 men with early prostate cancer. Their average age was 67. They were randomly assigned to have immediate surgery or no treatment. People in each group lived an average of about 13 years after the study began. Nearly 6% of men in the surgery group and just over 8% in the no-treatment group died of prostate cancer. That difference was small enough that it could have been caused by chance. But there was some evidence of benefit for men with a score of 10 or higher on the prostate-specific antigen (PSA) test. Prostate cancer deaths were 33% lower for men with these higher scores who had surgery rather than no treatment.
