GP Scoring
GP score was obtained by multiplying the preoperative total PSA value
with the prostate biopsy GS according to the definition of Soga N et al7. According to the distribution of scores, patients
were divided into 3 groups as low, intermediate and high risk
(<50, 50-100, >100).
After the patients were divided into risk groups with each predictive
model, the 1, 3 and 5 year (yr) BCR-free rates of the patients were
determined for each model. Also the accuracy of four predictive models
for predicting 1, 3 and 5-yr BCR was evaluated.
