Predicting prostate cancer’s return

For men who have undergone surgery for prostate cancer, their prostate specific antigen (PSA) level before surgery is still the best predictor of whether the cancer will return, say researchers at Johns Hopkins University. Investigators tracked more than 2,300 men who had their prostate removed and found that for every two-point increase in PSA before surgery, the risk for having their cancer recur doubled. They also found that higher PSA levels were associated with larger and more aggressive tumors. The study was published in the Journal of Urology.
