D’Amico risk classification
D’Amico risk classification was performed according to the preoperative
total PSA value, prostate biopsy GS and clinical T stages. According to
this classification, patients were divided into 3 groups as low risk,
intermediate risk and high risk. Patients with preoperative total PSA
<10 ng / dl, GS <7 and clinical stage cT1-2a were
considered low-risk group. Patients with total PSA 10-20 ng / dl or GS 7
or clinical stage cT2b were defined as intermediate-risk group. Lastly,
patients with total PSA value> 20 ng / dl or
GS> 7 or clinical stage cT2c were identified as the
high-risk group 3.
