Methods: Hundred and sixty-five patients who underwent radical prostatectomy and PLND between 2012 and 2018 in our clinics were included, and their data were retrospectively screened. Results: The mean age of patients was 63.6 ± 5.8 (range: 49–76) years. Hundred and thirty-five (81.8%) patients had a Briganti score of <5, whereas 30 (18.2%) had a Briganti score of ≥5. The preoperative T-PSA levels, biopsy grades and the incidence of T2b and T2c stages in patients with a Briganti score of ≥5 was significantly higher than that in patients with a Briganti score of <5 (p: .026; p: .000; p: .001, respectively). The incidence of lymph node positivity in patients with a Briganti score of ≥5 (76.7%) was significantly higher than that in patients with a Briganti score of <5 (25.2%) (p: .000). The sensitivity of the Briganti score to detect lymph node positivity was 40.35%, specificity was 93.52%, positive predictive value was 76.67% and the negative predictive value was 74.81%. The accuracy of the test was 75.15%. Conclusion: Nomograms provide useful information regarding prostate cancer. Risk estimates should be carefully considered, and treatment decisions should be given with a patient-specific approach.
