a
Tumors were considered high grade if they were given Gleason sum score ≥8, or G3 according to the former three‐level WHO grading system. Tumors graded low/intermediate had Gleason sum score ≤7, or G1‐G2 according to the former WHO grading system.
b
Prostate cancer cases were considered aggressive if they fulfilled at least one of the following criteria: High tumor grade, nonlocalized tumor (T3‐4), bone metastasis (M1), lymph node metastasis (N1), serum prostate‐specific antigen (PSA) >50 ng/mL or fatal prostate cancer outcome by January 2017.
