RT Journal Article SR Electronic T1 What’s new in prostate cancer screening and prevention? JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 439 OP 445 DO 10.3949/ccjm.76a.02009 VO 76 IS 8 A1 Eric A. Klein YR 2009 UL http://www.ccjm.org/content/76/8/439.abstract AB Prostate cancer is extremely common but causes death in only a minority of men in whom it develops, facts that raise issues regarding screening and treatment morbidity. Two large trials of screening with prostate-specific antigen (PSA) measurements came to seemingly opposite conclusions. Furthermore, a large trial of selenium and vitamin E found that these agents have no value as preventive agents.
