Risk Classification of Localized Prostate Cancer

Risk Classification	Definition
Very Low Risk	PSA＜10ng/mL, Gleason=6, T¹～T^2a, biopsy positive core rate＜34%, no cancer volume＞50% of biopsy volume, PSA density＜0.15ng/mL
Low Risk	PSA＜10ng/mL, Gleason=6, T¹～T^2a
Intermediate Risk	10ng/mL≤PSA＜20ng/mL, or Gleason=7, or T^2b～T^2c
Favorable Prognosis	Gleason=6 and 10ng/mL≤PSA＜20ng/mL, or Gleason 3+4=7 and PSA＜10ng/mL
Unfavorable Prognosis	Gleason 3+4=7 and (10ng/mL≤PSA＜20ng/mL or T^2b～T^2c), or Gleason 4+3=7 and PSA＜20ng/mL
High Risk	PSA≥20ng/mL, or Gleason=8～9, or ≥T³
