Gleason Scale



The Gleason Scale is a commonly-used medical testing device that is used to approximate the aggressiveness with which prostate cancer is spreading or the overall state of prostatic cancer in a patient. The Gleason Scale is also called the Gleason Score since it is essentially a medical test. It was developed at the Mayo Clinic in USA. The Gleason Scoring System was put forth by Dr. D. Gleason in 1966 and the system used by this noted pathologist is still in practice and regarded as very accurate in the medical fraternity.



Gleason & Prostate Cancer Symptoms

Management of prostate cancer is very demanding. The prostate is located in the male pelvis region, i.e. before the urinary bladder. The prostrate is a rather small organ, about the size of a walnut. Its main function is to produce the fluids that are needed during the act of ejaculation. It also plays some secondary role in the formation and expulsion of urine. Prostrate enlargement or cancer of the prostrate is a serious condition. It seeps-in very quietly and measuring the rate at which it spreads in the male body is very difficult. Further, prostate cancer can be very confusing for healthcare practitioners, since it often begins as benign prostatic enlargement which is largely understood as non-invasive, non-malignant or harmless. However, without any signs (absence of major symptoms), the condition can quickly take a very lethal form and become highly malignant. In fact, the entire change can happen within a few weeks. Thus, there is a constant need to probe the prostatic health of a patient once any kind of cancer-related, medical diagnosis has been made. This is where the use of a Gleason prostrate scale has come to the fore-it provides an undemanding method of observing the prostate's cancerous condition and that of the surrounding organs. The Gleason Score is widely regarded as an exact approximation of the degree up to which the prostrate cancer has become invasive in the body.

Understanding Gleason Score

Once cancer is diagnosed, a series of tests are performed on the prostrate. The most common test is a biopsy that is later used to arrive at a Gleason Score. Even if the prostate cannot be saved and has to be surgically removed, the medical facility will still insist for getting a Gleason Score from the removed prostatic tissue. The biopsy sample is put through a series of preparatory procedures grouped under Histological Evaluation. Then the sample is viewed under powerful microscopes. During this visual examination, the Gleason grades for various cells are calculated. The cells are compared with what a normal, non-cancerous prostate cell should look like and accordingly, the Gleason grading is done. It should be understood that the appearance of all cells, even the cancerous cells, is markedly different from each other. This is the core philosophy of grading various cells using the Gleason scoring system. Interpreting the Gleason Score Results is not difficult. As a thumb-rule, the lower the score, the better is the condition of the prostrate or lower are the chances of cancer becoming invasive in the body. This is why a Gleason scoring of 10 is regarded as a progressive condition of the cancer that needs immediate medical attention or there is a high chance of the patient's life being lost. For simple understanding of the Gleason scoring/grading system, the following comparison tool can be used:
