|What is a "Positive Margin" and what does it mean?|
A Positive Margin is when cancerous tissue is seen up to the edge of the specimen, when it is examined by the pathologist, after the prostate has been removed by Radical Prostatectomy. Removing all the cancer in the prostate with a negative margin is more likely to result in a cure than when a positive margin occurs*. The positive margin rate is a measure of a surgeon's success in removing all the cancer in Cancer of the Prostate. The lower a surgeon's positive margin rate, the more successful the surgeon is in removing all the cancer.
Associate Professor Harewood achieves a very low positive margin rate which is equal to the world’s best reported results. His overall positive margin rate for the first 200 patients on which he has operated is 7.3%. When the cancer is confined to the prostate gland (Organ confined or pT2) his positive margin rate is only 1.7%.
