Objective: To investigate and document the surgical, functional and oncological outcomes following surgery for high-risk prostate cancer patients. Patients and methods: Patients with pathological T3a, T3b and N1 disease were extracted from our prospectively updated institutional database. Data include demographics, preoperative cancer parameters, short and long-term complications and functional results. Details of biochemical recurrence, type and oncological outcome of salvage treatments, cancer-specific and overall survival were also obtained. Results: A total of 669 patients were included; 58.9% had T3a disease, 35.9% had pT3b and 11.4% N1 disease. With a median follow-up of 66 months (8–129), overall survival was 94.3%, cancer-specific survival was 98.7% and biochemical recurrence was 45.6%. Average inpatient stay was 1 day and the overall complication rate was 9.1%; 54.2% experienced a biochemical recurrence and 90.3% went on to have one or more salvage treatments, which were varied. Significant predictors of biochemical recurrence included pathological stage, any positive margin and patient age ( P<0.005). A total of 44.9% had an immediate biochemical recurrence, with 90% receiving subsequent treatment and 20.5% having a durable response. None of the patients receiving prostate bed radiotherapy alone had a durable response. 54% had a delayed biochemical recurrence, with 63.5% receiving subsequent treatment and 44% having a durable response. Conclusions: Surgery is associated with encouraging surgical and functional outcomes, cancer-specific survival and overall survival rates in these patients. Pathological stage is a significant predictor of biochemical recurrence. The present analysis shows that long-term observation for certain patients with biochemical recurrence is appropriate and questions the effectiveness of further local salvage treatments in patients with an immediate biochemical recurrence postoperatively.

Androgen deprivation therapy (ADT) is used to improve overall survival (OS) in prostate cancer treatment; however, we encountered that long-term ADT in elderly patients may be related to high other-cause mortality (OCM). This study aimed to confirm the potential risk associated with long-term ADT in elderly patients using a different large cohort. A comparison analysis was conducted between the ≥2- and <2-year ADT groups using open, large data from 1840 patients with clinically localized prostate cancer treated with radiotherapy (1172 treated with high-dose-rate brachytherapy (HDR) + external beam radiotherapy (EBRT) and 668 treated with external beam radiotherapy). The OCM-free survival (OCMFS), overall survival, and prostate cancer-specific survival rates were measured. The 10-year OCMFS rates in patients aged ≥75 years were 94.6% and 86% in the <2- and ≥2-year ADT groups, respectively, but were 96.3% and 93.5% (p = 0.0006) in their younger counterparts. If dividing into HDR and EBRT groups. This inclination was found in brachytherapy group but not in EBRT group. The overall survival rate was also lower in the elderly patients in the ≥2-year ADT group than in the <2-year ADT group; however, the 10-year prostate cancer-specific survival rate was the same in both groups. Long-term ADT in elderly patients resulted in not only higher OCM rates but also poorer OS rates; therefore, longer-term ADT in elderly patients should be performed with meticulous care.

Abstract Purpose A number of observational clinical studies suggest that prior primary tumor treatment favorably influences the course of metastatic prostate cancer (PCa), but its mechanisms of action are still speculative. Here, we describe the long-lasting sensitivity to various forms of androgen deprivation in patients after radical prostatectomy (RP) for locally advanced PCa as one potential mechanism. Methods A consecutive series of 115 radical prostatectomies after inductive therapy for T4 prostate cancer was re-analyzed, and long-term survival, as well as recurrence patterns and responses to different forms of hormonal manipulation, were assessed. Results The estimated biochemical response-free, PCa-specific, and overall survival rates after 200 months were 20%, 65%, and 47% with a median overall survival of 156 months. The majority of patients, although not cured of locally advanced PCa (84/115), showed long-term survival after RP. PCa-specific and overall survival rates of these 84 patients with biochemical recurrence were 61% and 44% at 150 months. Long-term sensitivity to ADT was found to be the main reason for the favorable tumor-specific survival in spite of biochemical recurrence. Conclusions Sensitivity to primary or secondary hormonal manipulation was the main reason for the long-term survival of patients who had not been cured by surgery only. The results suggest that treatment of the primary tumor-bearing prostate delays castration-resistant PCa and enhances the effect of hormonal therapies in a previously unknown manner. The underlying cellular and molecular mechanisms need to be explored in more detailed analyses, which could profoundly impact treatment concepts of locally advanced and metastatic PCa.

Background and Objectives: Significant numbers of prostate cancer (PCa) patients experience tumour upgrading and upstaging between prostate biopsy and radical prostatectomy (RP) specimens. The aim of our study was to investigate the role of grade and stage increase on surgical and oncological outcomes. Materials and Methods: Upgrading and upstaging rates were analysed in 676 treatment-naïve PCa patients who underwent RP with subsequent follow-up. Positive surgical margin (PSM), biochemical recurrence (BCR), metastasis-free survival (MFS), overall (OS) and cancer specific survival (CSS) were analysed according to upgrading and upstaging. Results: Upgrading was observed in 29% and upstaging in 22% of PCa patients. Patients undergoing upgrading or upstaging were 1.5 times more likely to have a PSM on RP pathology. Both upgrading and upstaging were associated with increased risk for BCR: 1.8 and 2.1 times, respectively. Mean time to BCR after RP was 2.1 years in upgraded cases and 2.7 years in patients with no upgrading (p < 0.001), while mean time to BCR was 1.9 years in upstaged and 2.8 years in non-upstaged cases (p < 0.001). Grade and stage increase after RP were associated with inferior MFS rates and ten-year CSS: 89% vs. 98% for upgrading (p = 0.039) and 87% vs. 98% for upstaging (p = 0.008). Conclusions: Currently used risk stratification models are associated with substantial misdiagnosis. Pathological upgrading and upstaging have been associated with inferior surgical results, substantial higher risk of BCR and inferior rates of important oncological outcomes, which should be considered when counselling PCa patients at the time of diagnosis or after definitive therapy.

Objective: Recently, the laparoscopic technique has become widely accepted as a minimally invasive modality which reduces morbidity and provides similar oncological outcomes to open surgery. However, the number of clinical trials comparing laparoscopic and open radical cystectomy are limited. The objectives of this study are to compare the long-term oncological outcomes between open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) for bladder cancer. Materials and Methods: Out of 144 radical cystectomy patients admitted to our institute from January 2006 to December 2016, 87 patients were categorized as being in the LRC group, and 57 patients in the ORC group. Baseline characteristics, perioperative variables, and pathology results were collected retrospectively. Oncological outcomes including overall survival (OS), recurrence-free survival (RFS) and cancer-specific survival (CSS) were analyzed and compared between the two groups. Results: The mean age of the patients was 64.19 ± 9.89 years in the ORC group and 61.90 ± 10.47 years in the LRC group. The most frequent urinary diversion procedure in both groups was ileal conduit. All pathology results between the LRC group and the ORC group showed no statistical significance. The median follow-up duration was 57.18 ± 44.68 months in the ORC group and 53.96 ± 34.97 months in the LRC group. There was no statistically significant difference in overall survival (OS), recurrence-free survival (RFS) and cancer-specific survival (CSS) between the groups (p = 0.322, 0.946, and 0.528, respectively). Conclusion: Our study demonstrated that the long-term oncological outcome of LRC is comparable to ORC in the management of bladder cancer. LRC is an alternative option to open radical cystectomy and is safe, effective, and feasible. However, further large comparative studies with adequate long-term follow-up are recommended to support our results.

Long Term Survival

65 Background: Mortality among men with biochemical failure (BF) after treatment is variable. We examined the long-term survival of men with BF to determine if differences exist, depending on original treatment modality. Methods: Between 1995 and 2008, 6,084 patients underwent treatment for clinically localized prostate cancer at our institution (4,276 underwent radical prostatectomy (RP); 1,808 underwent EBRT). Clinical information and follow up data was obtained from prospectively maintained databases. Survival was assessed using log rank test. Results: 526 (12%) patients had BF defined by PSA > 0.4 after RP. 326 (18%) patients had BF after EBRT, defined as PSA nadir +2. 197 (60%) of EBRT patients received ADT as neoadjuvant/concurrent/adjuvant therapy. Median overall survival was 154 months (95%CI 148-157) versus 129 months (95%CI 123-135) for RP and EBRT respectively (p<.0001). Median prostate cancer specific survival was 125 months (95%CI 93-148) versus 107 months (95%CI 92-123) for RP and EBRT respectively (p=0.17). There was no difference in prostate cancer specific survival between treatments among patients in D’Amico intermediate and high risk groups. Conclusions: In patients with biochemical recurrence after definitive treatment, patients treated with RP have improved overall survival compared to patients treated with EBRT. However, there is no difference among treatment groups in prostate cancer specific survival.

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.

The limitations of the biomarker prostate-specific antigen (PSA) necessitate the pursuit of biomarkers capable of better identifying high-risk prostate cancer (PC) patients in order to improve their therapeutic management and outcomes. Aggressive prostate tumors characteristically exhibit high rates of glycolysis and lipogenesis. Glycerol 3-phosphate phosphatase (G3PP), also known as phosphoglycolate phosphatase (PGP), is a recently identified mammalian enzyme, shown to play a role in the regulation of glucose metabolism, lipogenesis, lipolysis, and cellular nutrient-excess detoxification. We hypothesized that G3PP may relieve metabolic stress in cancer cells and assessed the association of its expression with PC patient prognosis. Using immunohistochemical staining, we assessed the epithelial expression of G3PP in two different radical prostatectomy (RP) cohorts with a total of 1797 patients, for whom information on biochemical recurrence (BCR), metastasis, and mortality was available. The association between biomarker expression, biochemical recurrence (BCR), bone metastasis, and prostate cancer-specific survival was established using log-rank and multivariable Cox regression analyses. High expression of G3PP in PC epithelial cells is associated with an increased risk of BCR, bone metastasis, and PC-specific mortality. Multivariate analysis revealed high G3PP expression in tumors as an independent predictor of BCR and bone metastasis development. High G3PP expression in tumors from patients eligible for prostatectomies is a new and independent prognostic biomarker of poor prognosis and aggressive PC for recurrence, bone metastasis, and mortality.
