Table 2 Scoring scale of Selection Score of Oncologic Safety

From: Oncological safety of intrafascial nerve-sparing radical prostatectomy compared with conventional process: a pooled review and meta-regression analysis based on available studies

Section Clinical T stage Preoperative PSA level (ng/ul)
Item T1c T2a T2b T2c T3 NS 0–2.5 2.6–4 4.1–6 6.1–10 > 10 NS
Score 5 4 3 2 1 0 5 4 3 2 1 0
Section Biopsy Gleason score Invaded cores percent (%)
Item 2–4 5–6 3 + 4 4 + 3 8–10 NS < 34 34–50 > 50 NS
Score 5 4 3 2 1 0 3 2 1 0
  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
