Abstract
Purpose: Specimen pathology findings collectively impact the long-term outcomes of robot-assisted laparoscopic prostatectomy. Since seminal vesicle invasion (SVI) is an important independent predictor of biochemical recurrence (BCR), this study was designed to evaluate the influence of isolated SVI in the absence of capsular/margin invasion on BCR. Material and Methods: Pathology reports of 2009 robot-assisted laparoscopic prostatectomy specimens were analyzed retrospectively excluding capsular breach and/or margin-positive cases to include 1409 patients in the study. Factors predicting SVI and BCR in this select group of patients were assessed and statistically analyzed. Survival analysis for PSA (prostate-specific antigen) failure probability and binomial regressions for variable predictability were performed. Results: The African American race was associated with SVI (p < 0.05). PSA had a directly proportional correlation with the occurrence of SVI and BCR. SVI was found to be an independent predictor of BCR, leading to higher odds of BCR at 5 years (odds ratio [OR] 8.2, 95% confidence interval [CI] 4.5-14.6, p < 0.0001). When the seminal vesicle was invaded, the specimen Gleason grade group (SGGG; OR 1.9, 95% CI 1.02-3.7, p = 0.04), PSA (OR 1.2, 95% CI 1.01-1.4, p = 0.03), and BMI (body mass index) (OR 1.2, 95% CI 1.04-1.5, p = 0.01) predicted BCR. Seminal vesicle involvement was not found in SGGG 1. Risk stratification of significant predictors of BCR with isolated SVI identified a subgroup with BMI ≤27.9 kg/m2, PSA ≤8.6 ng/mL, and SGGG 2, which had a significantly better prognosis (p = 0.029, log-rank test). Conclusions: Seminal vesicles are infrequently involved with SGGG 1. Select groups of patients with isolated SVI who have low-grade disease with relatively lower PSA and BMI do not have an aggressive biological behavior and are unlikely to have a BCR, thereby circumventing unnecessary adjuvant therapy with its attendant side effects. The BMI significantly predicted PSA failures and should be considered as an additional risk assessment tool.

Abstract
Patient-specific assessment, disease monitoring, and the development of an accurate early surrogate of the therapeutic efficacy of locally advanced prostate cancer still remain a clinical challenge. Contrary to prostate biopsies, circulating tumor cell (CTC) collection from blood is a less-invasive method and has potential as a real-time liquid biopsy and as a surrogate marker for treatment efficacy. In this study, we used size-based filtration to isolate CTCs from the blood of 100 prostate cancer patients with high-risk localized disease. CTCs from five time points: +0, +2, +6, +12 and +24 months were analyzed. Consenting treatment-naïve patients with cT3, Gleason 8-10, or prostate-specific antigen > 20 ng/mL and non-metastatic prostate cancer were included. For all time points, we performed 3D telomere-specific quantitative fluorescence in situ hybridization on a minimum of thirty isolated CTCs. The patients were divided into five groups based on the changes of number of telomeres vs. telomere lengths over time and into three clusters based on all telomere parameters found on diagnosis. Group 2 was classified as non-respondent to treatment and the Cluster 3 presented more aggressive phenotype. Additionally, we compared our telomere results with the PSA levels for each patient at 6 months of ADT, at 6 months of completed RT, and at 36 months post-initial therapy. CTCs of patients with PSA levels above or equal to 0.1 ng/mL presented significant increases of nuclear volume, number of telomeres, and telomere aggregates. The 3D telomere analysis of CTCs identified disease heterogeneity among a clinically homogeneous group of patients, which suggests differences in therapeutic responses. Our finding suggests a new opportunity for better treatment monitoring of patients with localized high-risk prostate cancer.

Abstract
PURPOSE Cryoablation has been proven as a less invasive, safe, and effective treatment for localized prostate cancer. We attempted to identify the predictors of biochemical recurrence after prostate cryoablation for localized prostate cancer in this study. METHODS We reviewed 114 patients who underwent primary whole-gland prostate cryoablation for localized prostate cancer from October 2008 to March 2013. The perioperative parameters included age >70 years, initial prostate-specific antigen (PSA), preoperative prostate volume, Gleason score, T stage, D'Amico risk group, postoperative PSA nadir, time to PSA nadir, and PSA biochemical recurrence, defined by Phoenix definition (nadir plus 2 ng/mL). Receiver operating characteristic (ROC) analysis was used for the best cutoff value of PSA nadir for PSA biochemical recurrence. The parameters were analyzed in binary logistic regression and Kaplan-Meier analysis for PSA biochemical recurrence. RESULTS A total of 31.6 % (N = 36) patients had PSA biochemical recurrence during the median follow-up of 34.87 ± 16.49 months. ROC analysis revealed that the best cutoff value for biochemical recurrence prediction was when the PSA nadir = 0.3 ng/mL. On multivariate analysis and Kaplan-Meier analysis, the D'Amico high-risk group [hazard ratio (HR) 6.552; p = 0.014], PSA nadir >0.3 ng/mL (HR 34.062; p < 0.001), and time to PSA nadir <3 months (HR 4.144; p = 0.021) were statistically significant for PSA biochemical recurrence. CONCLUSIONS The D'Amico high-risk group, postoperative PSA nadir >0.3 ng/mL, and time to PSA nadir <3 months predict biochemical recurrence in primary whole-gland prostate cryoablation.

Advanced imaging for the early diagnosis of local recurrence prostate cancer after radical prostatectomy. BIOMED RESEARCH INTERNATIONAL 2014; 2014:827265.

Abstract
Currently the diagnosis of local recurrence of prostate cancer (PCa) after radical prostatectomy (RT) is based on the onset of biochemical failure which is defined by two consecutive values of prostate-specific antigen (PSA) higher than 0.2 ng/mL. The aim of this paper was to review the current roles of advanced imaging in the detection of locoregional recurrence. A nonsystematic literature search using the Medline and Cochrane Library databases was performed up to November 2013. Bibliographies of retrieved and review articles were also examined. Only those articles reporting complete data with clinical relevance for the present review were selected. This review article is divided into two major parts: the first one considers the role of PET/CT in the restaging of PCa after RP; the second part is intended to provide the impact of multiparametric-MRI (mp-MRI) in the depiction of locoregional recurrence. Published data indicate an emerging role for mp-MRI in the depiction of locoregional recurrence, while the performance of PET/CT still remains unclear. Moreover Mp-MRI, thanks to functional techniques, allows to distinguish between residual glandular healthy tissue, scar/fibrotic tissue, granulation tissue, and tumour recurrence and it may also be able to assess the aggressiveness of nodule recurrence.

Abstract
Ureteral metastases of prostatic adenocarcinoma are very rare. We report the case of a 66-year-old man with a right ureteral metastasis of prostate cancer. Only 10 cases have been reported in the literature these last 30 years. Most patients had a multimetastatic prostate cancer. Local treatment is not standardized. Hormonotherapy seems to be the most appropriate treatment in first intention.

Abstract
PURPOSE To evaluate the accuracy of contrast-enhanced (18)F-choline PET/CT in restaging patients with prostate cancer after radical prostatectomy in relation to PSA, PSA velocity (PSAve) and PSA doubling time (PSAdt). METHODS PET/CT was performed in 49 patients (age range 58-87 years) with rising PSA (mean 4.13 ng/ml) who were divided in four groups according to PSA level: ≤1 ng/ml, 1 to ≤2 ng/ml, 2 to ≤4 ng/ml, and >4 ng/ml. PSAve and PSAdt were measured. PET and CT scans were interpreted separately and then together. RESULTS PET/CT diagnosed relapse in 33 of the 49 patients (67%). The detection rates were 20%, 55%, 80% and 87% in the PSA groups ≤1, 1 to ≤2, 2 to ≤4 and >4 ng/ml, respectively. PET/CT was positive in 7 of 18 patients (38.9%) with a PSA ≤2 ng/ml, and in 26 of 31 (83.9%) with a PSA >2 ng/ml. PET/CT was positive in 7 of 25 patients (84%) with PSAdt ≤6 months, and in 12 of 24 patients (50%) with PSAdt >6 months, and was positive in 26 of 30 patients (86%) with a PSAve >2 ng/ml per year, and in 7 of 19 patients (36.8%) with PSAve ≤2 ng/ml per year. PET alone was positive in 31 of 49 patients (63.3%), and of these 31 patients, CT was negative in 14 but diagnosed bone lesions in 2 patients in whom PET alone was negative. CT with the administration of intravenous contrast medium did not provide any further information. CONCLUSION Detection rate of (18)F-choline imaging is closely related to PSA and PSA kinetics. In particular, (18)F-choline PET/CT is recommended in patients with PSA >2 ng/ml, PSAdt ≤6 months and PSAve >2 ng/ml per year. CT is useful for detecting bone metastases that are not (18)F-choline-avid. The use of intravenous contrast agent seems unnecessary.

Abstract
Changes in quantitative D-dimer levels, circulating tumor cell (CTC) counts, and prostate-specific antigen (PSA) levels were measured in 28 patients with refractory castration-resistant prostate cancer to assess their concordance during the course of therapy and their relationship with risk of progressive disease. A significant correlation was identified between changes in PSA and both CTC counts and D-dimer levels (r = 0.67 and 0.58, respectively; P < .001). In addition, there was a significant correlation between changes in CTC count and D-dimer level (r = 0.62; P < .001). A significantly stronger concordance between these biomarkers was noted for increasing values (sensitivity, 72%-77.8%) compared with decreasing values (specificity, 43.8%-71.4%). Notably, increases in PSA and D-dimer levels, not CTC counts, were associated with increased risks for progressive disease (P < .024). Increases in quantitative D-dimer levels correlate with progressive disease better than CTC counts in patients with refractory prostate cancer.

Abstract
The fact that external beam radiotherapy and brachytherapy are now considered to be curative techniques has led to major review of the modalities of follow-up after radiotherapy for prostate cancer. The problem concerns both the diagnosis of recurrence, rapidly announced by elevation of prostatic-specific antigen (PSA), usually at a subclinical stage, and the validity of criteria of biochemical recurrence to allow comparison of various study. Physicians involved in follow-up should be aware of the potential of bounce in PSA follow-up after external beam radiotherapy or brachytherapy. The PSA bounce phenomemon was defined by a rise of PSA values (+0.1 -0.8 ng/ml) with a subsequent fall. Biochemical failure after external beam radiotherapy or brachytherapy (with or without hormonotherapy) was defined by Phoenix criteria by a rise of 2 ng/ml above an initial PSA nadir. This definition was more correlated to PSA bounce phenomenon.
