Abstract
Introduction
The aim of study was to establish pretreatment and postoperative factors which could predict the early biochemical recurrence after radical prostatectomy.
Materials and method
754 patients had undergone radical prostatectomy since January 2002 to December 2008 in our department and were included in this prospective study. Exclusion criteria were: neoadjuvant or adjuvant treatment (radiation or hormonal treatment) and N+. Following parameters were evaluated: age, PSA at time of biopsy, time period from biopsy to operation, biopsy and postoperative Gleason score, stage, high grade intraepithelial neoplasias, perineural invasion. Biochemical recurrence was detected if PSA value after radical prostatectomy was ≥0.2 ng/ml. All factors likely to be predictive were evaluated by univariate analysis (Log-rank test). Multivariate analysis using Cox model was completed for all factors with p value <0.1 at univariate analysis.
Results
Final analysis was done using data of 496 patients. We detected 53 (10.7%) biochemical recurrences. Calculated actuarial biochemical recurrence free survival reached 64%. Multivariate analysis highlighted that PSA >10 ng/ml (HR 2.45, p = 0.008), pathological stage ≥pT3 (HR 2.371, p = 0.02), postoperative Gleason score ≥7 (HR 2.149, p = 0.049), positive surgical margins (HR 2.482, p = 0.014) and absence of high grade intraepithelial neoplasia in removed prostate (HR 0.358, p = 0.006) are independent factors influencing biochemical recurrence after radical prostatectomy.
Conclusion
Patients with higher PSA, locally advanced disease, positive surgical margins, and Gleason score ≥7 are at the highest risk for biochemical recurrence.
