ONCOLOGIC OUTCOMES OF RADICAL PROSTATECTOMY AND PROGNOSTIC STRATIFICATION IN PATIENTS WITH CLINICALLY LOCALLY ADVANCED PROSTATE CANCER

Abstract

Oncologic outcomes of radical prostatectomy in 106 patients with clinically locally advanced prostate cancer were demonstrated. The mean follow-up was 50.6 (12-129) months. 5-year recurrence-free survival was 47.7 %, 5-year cancer-specific and overall survival - 85.8 %. Patients were devided into three different risk groups: low risk patients had PSA level <20 ng/ml, biopsy Gleason score ≤6 and absence of the seminal vesicle invasion of cancer; intermediate risk was noted when the patient had only one of poor prognostic factors (PSA ≥20 ng/ml or biopsy Gleason score≥7 or presence of cancer invasion to the seminal vesicle) and high risk patients had 2 or 3 poor prognostic factors. For patients of low, intermediate and high risk the biochemical reccurence rates were 14.3 %, 37.1 % and 70.2 %, respectively (p=0.002). The patients of intermediate and high risk had clinically significant higher risk of biochemical reccurence than those of low risk with odds ratio 3.0 and 8.5, respectively. Such grouping may help in guiding the individualized treatment for these patients.
