Gleason score : ウィキペディア英語版 | Gleason grading system
The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy. A Gleason score is given to prostate cancer based upon its microscopic appearance.〔(【引用サイトリンク】title=Male Genital Pathology )〕 Cancers with a higher Gleason score are more aggressive and have a worse prognosis. ==Specimens and processing== Most often, a urologist or radiologist will remove a cylindrical sample (biopsy) of prostate tissue through the rectum, using hollow needles, and biomedical scientists in a Histology laboratory prepare microscope slides for H&E staining and Immunohistochemistry for diagnosis by a pathologist. If the prostate is surgically removed, a pathologist will slice the prostate for a final examination.
