Rapid Rise in PSA Levels a Poor Predictor of Prostate Cancer

Blood tests that indicate prostate-specific antigen (PSA) levels are rising rapidly over time are of little use in detecting aggressive prostate cancer and should not be done, a new study indicates. The study found that PSA velocity doesn't add any useful information beyond what physicians can already tell from other methods of prostate cancer screening, including the one-time PSA level test and digital rectal exams. Results are leading to hypotize the presence of many unnecessary biopsies, due to compliance to current screening guidelines that recommend biopsies for men who have high PSA velocity but no other signs of prostate cancer -- such as a suspected abnormality during a digital rectal exam or high PSA level during a single test.
