Introduction and Objectives. Despite refinements in the initial evaluation and management of patients with newly diagnosed localized high-risk prostate cancer, urologist have difficulties to counsel their patients based upon currently used pretreatment parameters. In this study, we investigate preoperative characteristics that can predict unfavorable pathological outcome in patients undergoing radical prostatectomy for clinically localized high-risk prostate cancer. Materials and Methods. We analyzed a database of 279 patients diagnosed with prostate cancer and treated with radical prostatectomy in our institute between 2014 and 2017 and identified 83 patients with high-risk characteristics because of PSA > 20 ng/ml or biopsy Gleason score ³ 8. The following postsurgical parameters were considered unfavorable pathological outcome: seminal vesicle invasion, surgical margins, perineural invasion and lymph node invasion. To identify the determinants associated with unfavorable pathologic outcomes, we performed univariate and multivariate logistic regression in two models. Results. 77.1% of patients (n=64) had unfavorable pathological outcome. In multivariate analysis, we pointed out that PSA > 20 ng/ml was an independent determinant associated with lymph node invasion ( OR: 3.7, 95 % CI: 1.02- 14.36, p=0.04), biopsy Gleason score ≥ 8 was independently associated with increased risk of perineural invasion ( OR: 6.04, 95% CI: 1.09-33.31, p=0.03) and PSA > 20 ng/ml and biopsy Gleason score ≥ 8 were independent high risk factors for seminal vesicle invasion (OR: 11.10, 95% CI: 1.30-98.44, p=0.02; OR: 11.45, 95% CI: 1.28-102, p=0.02, respectively). Moreover, in the second model, we showed that Gleason score pattern 5 increased the risk of lymph node invasion by 3.21 (OR: 3.21, 95% CI: 1.03-9.99, p=0.04). Conclusions. Newly diagnosed patients with PSA > 20 ng/ml or biopsy Gleason score≥ 8 are at increased risk of more extensive disease. Our data is important for urologist in the selection of patients with high risk characteristics proposed for radical prostatectomy and for patients to better understand their disease.
