‡ Risk groups according to modification of the National Comprehensive Cancer Network. Low risk: T1 to 2, Gleason score 2 to 6, and PSA < 10ng/mL. Intermediate risk: T1 to 2, Gleason score 7, and/or PSA 10 to <20ng/mL. High risk: T3, and/or Gleason score 8 to 10, and/or PSA 20 to <50ng/mL. Regionally metastatic disease: T4 and/or N1 and/or PSA 50 to <100ng/mL in the absence of distant metastases (M0 or Mx). Distant metastases: M1 and/or PSA ≥100ng/mL.
