  1. This scoring scale was according to the Partin table and D’Amico’s study, stratified to 4 parts including clinical stage, preoperative PSA level, Gleason score and invaded cores percent. Scores of the 4 parts were summed to the Selection Score of Oncologic Safety (SSOS). High score means the more rigorous selection criteria for patients and low risk of extraprostatic extension and margin involvement. PSA prostate-specific antigen, NS not evaluated
