The prognosis of prostate cancer relies on the outcome of prostate biopsy. If there are positive signals from a digital anal exam or PSA test then the chances of a patient having prostate cancer become greater. Further tests are then recommended such as biopsy of the prostate.
A biopsy is performed employing a thin, long needle which is put into the insides of the prostate through the colon wall. The whole process is checked by ultrasound. The needle takes a little piece of prostate tissue from six of the regions from across the prostate gland.
These are the base, top, middle, on every side of the prostate. After this process the the selected tissue samples are studied by cytologist to check for the presence of cancer-infected cells.
Doctor - cytologist evaluates every one of the two pieces on the Gleason score from 1 to 5 points. This scale is based on certain microscopic characteristics of cancerous cells and reflects the aggressiveness of the cancer.
The Gleason score is also used to appraise the seriousness of histologic prostate cancer. High values of Gleason score are associated with a poor prognosis outcome. The two most characteristic areas of the biopsy are assessed on a 5 point scale. The resulting make up of these assessments, "Gleason sum" differs from 2 to 10 scores.
The key application of Gleason score is an appraisal of the danger of death from prostate cancer. As mentioned the limits of prostate cancer has a direct result on diagnosis. Recent research has shown that patients with a power of 2 - 4 Gleason possibility of death inside 15 years is small (4 - 7%), whereas when the degree of 8 - 10 on this scale match to a high level of mortality (60 - 87%).
In a conclusion, we can say that Gleason Scale is used to explain evil cancers uncovered by a prostate biopsy. The bigger the amount of Gleason score is, the more assertive is the malignant tissue. The score is calculated on sections of cells of a cancer of the prostate gland.
