To the Editor:Prostate cancer is one of the most common malignant tumors of the male genital system,with approximately 1.1 million new cases in 2012.[1]The accurate diagnosis of prostate cancer leads to a better chance of successful treatment when it is still confined to the prostate gland.The Gleason grading(GD)system was first established by Donald Gleason during 1966 to 1974.[2,3]The Gleason pattern ranges from 1 to 5.A higher score corresponds to poorer differentiation,which indicates a worse prognosis and higher metastasis possibility.The total score is calculated with the first half of the dominant Gleason pattern and the second half based on the non-dominant one.
