Despite recent claims by some urologists that measuring the blood protein prostate-specific antigen (PSA) may not be effective in predicting risk of prostate cancer, a Johns Hopkins study of more than 2,000 men confirms that PSA remains the best measure of the likelihood of cancer recurrence after surgery.
Results of the study, published in the October issue of The Journal of Urology, demonstrated that men with high PSA levels prior to prostate removal surgery were significantly more likely to have advanced clinical stages of cancer, evidence of higher grade cancers in surgically removed tissue, and spread of cancer cells beyond the prostate. In addition, increasing PSA was significantly associated with increased risk of cancer recurrence after surgery, even in men with lower PSA levels prior to surgery.
The study was led by Stephen J. Freedland, M.D., clinical instructor of urology, and Alan W. Partin, M.D., Ph.D., professor and chair of urology at Johns Hopkins Brady Urological Institute.
