Background Some studies have reported that deletions at chromosome arm 9p occur frequently and represent a critical step in carcinogenesis of some neoplasms. Our aim was to evaluate the deletion of locus 9p21 and chromosomes 3, 7 and 17 in localized prostate cancer (PC) and correlate these alterations with prognostic factors and biochemical recurrence after surgery. Methods We retrospectively evaluated surgical specimens from 111 patients with localized PC who underwent radical prostatectomy. Biochemical recurrence was defined as a prostate-specific antigen (PSA) >0.2 ng/mL and the mean postoperative follow-up was 123 months. The deletions were evaluated using fluorescence in situ hybridization with centromeric and locus-specific probes in a tissue microarray containing 2 samples from each patient. We correlated the occurrence of any deletion with pathological stage, Gleason score, ISUP grade group, PSA and biochemical recurrence. Results We observed a loss of any probe in only 8 patients (7.2%). The most common deletion was the loss of locus 9p21, which occurred in 6.4% of cases. Deletions of chromosomes 3, 7 and 17 were observed in 2.3%, 1.2% and 1.8% patients, respectively. There was no correlation between chromosome loss and Gleason score, ISUP, PSA or stage. Biochemical recurrence occurred in 83% cases involving 9p21 deletions. Loss of 9p21 locus was significantly associated with time to recurrence (p = 0.038). Conclusions We found low rates of deletion in chromosomes 3, 7 and 17 and 9p21 locus. We observed that 9p21 locus deletion was associated with worse prognosis in localized PC treated by radical prostatectomy.

Introduction: We sought to determine predictors for early and late biochemical recurrence following radical prostatectomy among localized prostate cancer patients.Methods: The study included localized prostate cancer patients treated with radical prostatectomy (RP) at the University of Southern California from 1988 to 2008. Competing risks regression models were used to determine risk factors associated with earlier or late biochemical recurrence, defined using the median time to biochemical recurrence in this population (2.9 years after radical prostatectomy).Results: The cohort for this study included 2262 localized prostate cancer (pT2-3N0M0) patients who did not receive neoadjuvant or adjuvant therapies. Of these patients, 188 experienced biochemical recurrence and a subset continued to clinical recurrence, either within (n=19, 10%) or following (n=13, 7%) 2.9 years after RP. Multivariable stepwise competing risks analysis showed Gleason score ≥7, positive surgical margin status, and ≥pT3a stage to be associated with biochemical recurrence within 2.9 years following surgery. Predictors of biochemical recurrence after 2.9 years were Gleason score 7 (4+3), preoperative prostate-specific antigen (PSA) level, and ≥pT3a stage.Conclusions: Higher stage was associated with biochemical recurrence at any time following radical prostatectomy. Particular attention may need to be made to patients with stage ≥pT3a, higher preoperative PSA, and Gleason 7 prostate cancer with primary high-grade patterns when considering longer followup after RP.

80 Background: There are limited prospective data comparing outcomes of Open Radical Prostatectomy (ORP) and Robot-Assisted Laparoscopic Radical Prostatectomy (RALRP) for clinically localized prostate cancer. Our aim was to compare ORP and RALRP with respect to cancer control outcomes. Methods: A prospective analysis of data from the University of Alberta Radical Prostatectomy Database was performed. Between September 2007 and August 2010, 1019 consecutive men underwent radical prostatectomy for clinically localized prostate cancer. The surgical approach was selected by the surgeon. The outcomes were biochemical recurrence (BCR) and positive surgical margins (PSM). BCR was defined as a PSA ≥ 0.1 ng/ml followed by a subsequent confirmatory value or initiation of salvage therapy. PSM was defined as the presence of cancer at the inked margin in the radical prostatectomy specimen. The Kaplan-Meier method was used to estimate biochemical recurrence free survival (BCRFS). Univariable and multivariable analyses were used to determine the association between surgical approach and outcomes. Results: Data were evaluable for 1014 out of 1019 patients. 204 patients underwent ORP and 810 patients underwent RALRP. The median follow-up duration was 21 months (IQR 12 to 29). Baseline characteristics were similar between the groups. In univariable analysis, 3-year BCRFS (90.6% versus 88.9%), overall PSM (26.5% versus 28.8%), and stage-stratified PSM (pT2: 19.9% versus 21.8%; pT3: 40.6% versus 49.1%) did not differ between the groups (all comparisons p>0.05). In multivariable analysis, surgical approach was not independently associated with BCR (HR 0.77, 95% CI 0.43 to 1.37, p=0.37) or PSM (OR 1.2, 95% CI 0.80 to 1.67, p=0.44). Conclusions: ORP and RALRP provided comparable short-term oncologic efficacy. Extended follow-up of the prospective cohort is needed to confirm these preliminary findings.

Abstract Background To compare the functional and oncological outcomes between innovative “three-port” and traditional “four-port” laparoscopic radical prostatectomy (LRP) in patients with prostate cancer (PCa). Methods We retrospectively collected the data of PCa patients treated at our institutions from June 2012 to May 2016. According to the inclusion criteria, a total of 234 patients were included in the study, including 112 in group A (four-port) and 122 in group B (three-port). The perioperatively surgical characteristics, functional and oncological outcomes were compared between groups. Results There were no statistical differences in the baseline parameters between these two groups. Compared with group A, the operative time (OT) and estimated blood loss (EBL) were significantly less in group B. On follow-up, the rate of positive surgical margin (PSM), prostate specific antigen (PSA) biochemical recurrence and continence after LRP did not show any statistically significant difference between the groups. An identical conclusion was also received in comparison of overall survival (OS) and biochemical recurrence-free survival (BRFS) between both groups. Conclusions Innovative “three-port” LRP can significantly shorten the OT and reduce the EBL compared with the traditional “four-port” LRP. Meanwhile, it does not increase the rate of PSM and PSA biochemical recurrence. “Three-port” LRP could be popularized in the future in view of its superior surgical technique, considerably better functional outcomes and remarkable oncological control.
