Post surgery; the pathologist will do a complete analysis of the entire prostate and will provide an accurate Gleason score. In my case a Gleason 3+4 was upgraded to a Gleason 4+3 which put me at a higher risk. Although my post RP PSA was < .008 my PSA began to slowly rise which 4 years later led to Salvage Radiation along with 2 injections of Zoladex. 18 months later my PSA continues to be < .008 although my Testosterone level is virtually zero and my radiation oncologist suggested that at my age of 81 that it may never come back. In the meantime I keep exercising as much as possible. Everyone's journey will be different but the post surgery pathology report will provide you with more accurate information then you had going in to surgery.
