Abstract
BACKGROUND Most prostate cancer (PCa) patients with a biochemical failure following primary multimodality treatment (surgery and postoperative radiotherapy) relapse in the nodes. OBJECTIVE To perform a matched-case analysis in men with lymph node recurrent PCa comparing standard of care (SOC) with metastasis-directed therapy (MDT). DESIGN, SETTING, AND PARTICIPANTS PCa patients with a prostate-specific antigen (PSA) progression following multimodality treatment were included in this retrospective multi-institutional analysis. INTERVENTION The SOC cohort (n=1816) received immediate or delayed androgen deprivation therapy administered at PSA progression. The MDT cohort (n=263) received either salvage lymph node dissection (n=166) or stereotactic body radiotherapy (n=97) at PSA progression to a positron emission tomography-detected nodal recurrence. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint, cancer-specific survival (CSS), was analyzed using the Kaplan-Meier method, log-rank test, Cox proportional hazards models, and propensity score-matched analyses. RESULTS AND LIMITATIONS At a median follow-up of 70 (interquartile range: 48-98) mo, MDT was associated with an improved CSS on univariate (p=0.029) and multivariate analysis (hazard ratio: 0.33, 95% confidence interval [CI]: 0.17-0.64) adjusted for the year of radical prostatectomy (RP), age at RP, PSA at RP, time from RP to PSA progression, Gleason score, surgical margin status, pT- and pN-stage. In total, 659 men were matched (3:1 ratio). The 5-yr CSS was 98.6% (95% CI: 94.3-99.6) and 95.7% (95% CI: 93.2-97.3) for MDT and SOC, respectively (p=0.005, log-rank). The main limitations of our study are its retrospective design and lack of standardization of systemic treatment in the SOC cohort. CONCLUSIONS MDT for nodal oligorecurrent PCa improves CSS as compared with SOC. These retrospective data from a multi-institutional pooled analysis should be considered as hypothesis-generating and inform future randomized trials in this setting. PATIENT SUMMARY Prostate cancer patients experiencing a lymph node recurrence might benefit from local treatments directed at these lymph nodes.

Abstract
BACKGROUND Breast cancer anti-estrogen resistance 1 (BCAR1/p130cas) is a hub for diverse oncogenic signaling cascades and promotes tumor development and progression. METHODS To understand the effect of BCAR1 in prostate cancer, we analyzed its expression on more than 11,000 prostate cancer samples. BCAR1 expression levels were compared with clinical characteristics, PSA recurrence, molecular subtype defined by ERG status and 3p, 5q, 6q and PTEN deletion. RESULTS BCAR1 staining was barely detectable in normal prostate glands but seen in 77.6% of 9472 interpretable cancers, including strong expression in 38.5%, moderate in 23.2% and weak in 15.9% of cases. BCAR1 up regulation was associated with positive ERG status (p < 0.0001), high Gleason score (p < 0.0001), advanced pathological tumor stage (p = 0.0082), lower preoperative PSA level (p < 0.0001), increased cell proliferation (p < 0.0001), early PSA recurrence (p = 0.0008), and predicted prognosis independently from clinico-pathological parameters available at the time of the initial biopsy. However, subset analyses revealed that the prognostic impact of BCAR1 expression was limited to ERG-negative cancer. That BCAR1 up regulation was linked to almost all analyzed deletions (p < 0.0001 each for PTEN, 5q, 6q deletion) may suggest a functional link to genomic instability. CONCLUSION The results of our study identify BCAR1 as a prognostic biomarker with potential clinical value for risk stratification of ERG-negative prostate cancer.

Abstract
FOXA1 (Fork-head box protein A1, HNF-3a) is a transcription factor involved in androgen signaling with relevance for lineage-specific gene expression of the prostate. The expression was analyzed by immunohistochemistry on a tissue microarray containing 11152 prostate cancer specimens. Results were compared with tumor phenotype, biochemical recurrence, androgen receptor expression, ETS-related gene (ERG) status and other recurrent genomic alterations. FOXA1 expression was detectable in 97.6% of 8227 interpretable cancers and considered strong in 28.5%, moderate in 46.2% and weak in 22.9% of cases. High FOXA1 expression was associated with TMPRSS2:ERG rearrangement and ERG expression (P < 0.0001). High FOXA1 expression was linked to high Gleason grade, advanced pathological tumor (pT) stage and early PSA recurrence in ERG negative cancers (P < 0.0001), while these associations were either weak or absent in ERG positive cancers. In ERG negative cancers, the prognostic role of FOXA1 expression was independent of Gleason grade, pathological tumor stage, lymph node stage, surgical margin status and preoperative PSA. Independent prognostic value became even more evident if the analysis was limited to preoperatively available features such as biopsy Gleason grade, preoperative PSA, cT stage and FOXA1 expression (P < 0.0001). Within ERG negative cancers, FOXA1 expression was also strongly associated with PTEN and 5q21 deletions (P < 0.0001). High expression of FOXA1 is an independent prognostic parameter in ERG negative prostate cancer. Thus, FOXA1 measurement might provide clinically useful information in prostate cancer.

Comparison of 11 Active Surveillance Protocols in Contemporary European Men Treated With Radical Prostatectomy. Clin Genitourin Cancer 2017; 16:S1558-7673(17)30246-X. [PMID: 28942009 DOI: 10.1016/j.clgc.2017.08.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2017] [Revised: 08/03/2017] [Accepted: 08/12/2017] [Indexed: 01/16/2023]
Abstract
BACKGROUND The aim of this study was to compare 11 active surveillance (AS) protocols in contemporary European men treated with radical prostatectomy (RP) at the Martini-Clinic Prostate Cancer Center. PATIENTS AND METHODS Analyzed were 3498 RP patients, from 2005 to 2016, who underwent ≥ 10 core biopsies and fulfilled at least 1 of 11 examined AS entry definitions. We tested proportions of AS eligibility, ineligibility, presence of primary Gleason 4/5, upstage, and combinations thereof at RP, as well as 5-year biochemical recurrence-free survival (BFS). RESULTS The most and least stringent criteria were very low risk National Comprehensive Cancer Network and Royal Marsden with 18.8% and 96.1% of AS-eligible patients, respectively. Rates of primary Gleason 4/5 at RP, upstaging, or both features, respectively, ranged from 2.3% to 6.7%, 6.1% to 18.2%, and 7.1% to 21.0% for those 2 AS entry definitions. The range of individuals deemed AS-ineligible between the same 2 AS entry definitions, despite not harboring unfavorable pathology (primary Gleason pattern 4/5, upstage, or both), was 80.3% to 3.7%, 78.3% to 3.4%, and 77.8% to 3.4%, respectively. BFS rates showed narrow variability, with a range of 85.9% to 91.8%. CONCLUSION Use of stringent AS entry definitions reduces the number of AS-eligible patients, which is related to a select range in individual entry parameters. Moreover, rates of unfavorable pathology at RP as much as tripled between most and least stringent AS entry definitions. However, less stringent AS entry definitions result in the lowest AS-ineligibility rates, in men without unfavorable pathology. BFS rates were virtually invariably high. Clinicians should know differences in key parameters underlying each AS entry definition, associated effect on rates of eligibility, and potential misclassification of individuals.

Does Cytoreductive Prostatectomy Really Have an Impact on Prognosis in Prostate Cancer Patients with Low-volume Bone Metastasis? Results from a Prospective Case-Control Study. Eur Urol Focus 2017; 3:646-649. [PMID: 28753877 DOI: 10.1016/j.euf.2017.06.016] [Citation(s) in RCA: 53] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2017] [Revised: 06/15/2017] [Accepted: 06/27/2017] [Indexed: 11/17/2022]
Abstract
The impact of cytoreductive radical prostatectomy (CRP) on oncological outcomes in patients with prostate cancer (PCa) and distant metastases has been demonstrated by retrospective data with their potential selection bias. Using prospective institutional data, we compared the outcomes between 43 PCa patients with low-volume bone metastases (1-3 lesions) undergoing CRP (median follow-up 32.7 mo) and 40 patients receiving best systemic therapy (BST; median follow-up 82.2 mo). The inclusion criteria for both cohorts were identical. So far, no significant difference in castration resistant-free survival (p=0.92) or overall survival (p=0.25) has been detected. Compared to recent reports, the outcomes for our control group are more favorable, indicating a potential selection bias in the previous retrospective studies. Therefore, the unclear oncological effect has to be weighed against the potential risks of CRP. However, patients benefit from a significant reduction in locoregional complications (7.0% vs 35%; p<0.01) when undergoing CRP. PATIENT SUMMARY In this study we analyzed the impact of surgery in patients with prostate cancer and bone metastases. Using prospective data, we could not show a significant benefit of surgery on survival, but the rate of locoregional complications was lower. Therefore, patients should be treated within prospective trials evaluating the role of cytoreductive prostatectomy in low-volume, bone metastatic prostate cancer.

Abstract
5069 Background: In this study we present the retrospective validation of the prognostic prostate cancer biomarker PDE4D7 in predicting longitudinal biological outcomes in a historical cohort of radical prostatectomy patients. Methods: Biopsy punches from 550 patients were collected from a representative tumor area of FFPE surgical resections. RNA was extracted and PDE4D7 quantified by one-step RT-qPCR. PDE4D7 scores were calculated by normalization of PDE4D7 to the averaged expression of four reference genes. The independent prognostic value of the PDE4D7 scores were evaluated using uni- and multivariate Cox proportional hazard regression. Multivariate analyses were adjusted for clinical prognostic variables. Post-surgical outcomes tested were: PSA relapse, start of salvage treatment, progression to metastases, overall and prostate cancer specific mortality. Logistic regression was used to create a combined prognostic model of PDE4D7 with clinical risk and tested in outcome prediction. Results: The PDE4D7 score was significantly associated with time to PSA failure after prostatectomy (HR 0.53; 95% CI 0.41-0.67 for each unit increase; p < 1.0E-04). After adjustment for pathology Gleason, pT stage, surgical margin status, and seminal vesicle invasion the HR was 0.55 (95% CI 0.43-0.72; p < 1.0E-04). Patients with a high PDE4D7 score that were clinically classified as intermediate to high risk of progression were re-classified into a group with an average progression risk less than the average cohort risk of clinically very low risk patients. The maximum benefit, compared to Gleason score, was observed in the clinically intermediate favorable risk group. Combining clinical risk with PDE4D7 scores improved the overall risk stratification. Conclusions: The PDE4D7 score has potential to provide independent risk information and, in particular, to re-stratify patients with clinical intermediate to high risk characteristics to a very low risk profile.

Abstract
Prostate cancer is notorious for its heterogeneity, which poses a problem for the applicability of diagnostic molecular markers. However, heterogeneity analysis can provide valuable information on the chronology in which molecular alterations arise. Here, we constructed a heterogeneity tissue microarray (TMA) comprising samples from 10 different tumor areas of 189 prostate cancers each in order to study the sequence of two frequent molecular alterations, i.e. 6q15 deletion and TMPRSS2:ERG fusion. Previous work shows a marked inverse relationship between these alterations, suggesting that presence of one of these alterations might impact development of the other. 6q15 deletion was analyzed by fluorescence in situ hybridization and ERG-expression by immunohistochemistry. Only 6.6% of 334 ERG-positive but 28.4% of 440 ERG-negative TMA spots showed 6q15 deletions (p < 0.0001). A breakdown of these data to the level of tumor foci revealed 6q deletions in 138 tumor foci that were large enough to have at least 3 analyzable TMA spots. These included 42 tumor foci with homogeneous ERG positivity and 16 with homogeneous 6q15 deletions. Remarkably, six of the 42 homogeneously ERG-positive tumor foci (14.3%) harbored small 6q15-deleted areas, but none of the 34 6q15-deleted foci showed areas of ERG positivity (p = 0.022). In conclusion, our data suggest that ERG-fusion can precede 6q15 deletion, but not vice versa. The complete absence of ERG-positive tumor areas in 6q15-deleted tumor foci further suggest that the functional consequences of 6q15 deletions may prevent the development of TMPRSS2:ERG fusions.

Abstract
Deletion of 12p is a recurrent alteration in prostate cancer, but the prevalence and clinical consequences of this alteration have not been studied in detail. Dual labeling fluorescence in situ hybridization using probes for 12p13 (CDKN1B; p27) and centromere 12 as a reference was used to successfully analyze more than 3700 prostate cancers with clinical follow-up data assembled in a tissue microarray format. CDKN1B was selected as a probe because it is located in the center of the deletion, which spans > 10 Mb and includes > 50 genes in 80% of cancers with 12p deletion. Deletion of 12p was found in 13.7% of cancers and included 13.5% heterozygous and 0.2% homozygous deletions. 12p deletion were linked to advanced tumor stage (p < 0.0001), high Gleason grade (p < 0.0001), rapid tumor cell proliferation (p < 0.0001), lymph node metastasis (p = 0.0004), and biochemical recurrence (p = 0.0027). Multivariate analysis including pT stage (p < 0.0001), Gleason grade (p < 0.0001), pN status (p = 0.0001), preoperative PSA levels (p = 0.0001), and resection margin status (p = 0.0001) revealed an independent prognostic value of 12p deletion (p = 0.0014). Deletion of 12p was unrelated to the ERG fusion status. Deletion of 12p was only marginally linked to reduced p27 expression, which by itself was unrelated to clinical outcome. This argues against p27 as the key target gene of 12p deletions. In summary, the results of our study demonstrate that 12p deletion is frequent in prostate cancer and provides independent prognostic information. 12p deletion analysis alone, or in combination with other prognostic parameters may thus have clinical utility.

Abstract
PURPOSE The impact of repeat biopsy sessions on radical prostatectomy remains controversial regarding perioperative, pathological and oncologic outcome. MATERIALS AND METHODS We analyzed the records of 12,624 patients who underwent radical prostatectomy from 2007 to 2013. The association of the number of biopsy sessions (range 1 to 3 or more) with pathological outcomes and perioperative complications was analyzed using the Wilcoxon matched pair test. To test the association between biopsy sessions and biochemical recurrence-free survival we used Kaplan-Meier curves and multivariable Cox regression analysis. RESULTS Of the patients 89.2% had 1 biopsy session, 7.4% had 2 sessions and 3.4% had 3 or more sessions. Median followup was 36.6 months. In patients with 1, 2 and 3 or more biopsy sessions prostate volume (38, 44 and 45 ml) and prostate specific antigen (6.7, 7.6 and 10.1 ng/ml, respectively) were greater (each p <0.001). The perioperative outcome was more favorable. Patients with 1, 2 and 3 or more biopsy sessions more often had organ confined tumors (67.6%, 72.1% and 72.9%, p = 0.003) and higher tumor volume (3.1, 3.0 and 3.6 ml, p <0.001) but a lower tumor percent (7.5%, 3.7% and 2.4%, respectively, p <0.001). More biopsy sessions were associated with fewer lymph node metastases (1, 2 and 3 sessions 0.23, 0.13 and 0.17, respectively, p <0.001). Gleason score and surgical margin status did not differ. The overall biochemical recurrence rate was 18.9% and it was comparable among the biopsy groups. No association was found between the number of biopsies and biochemical recurrence. CONCLUSIONS Patients with multiple biopsy sessions experience a slightly more favorable pathological outcome without an impact on the oncologic outcome. The perioperative outcome was more favorable in patients with multiple biopsies.

Abstract
OBJECTIVE To retrospectively assess the rate of high-grade primary Gleason upgrading (HGPGU) to primary Gleason pattern 4 or 5 in a contemporary cohort of patients with D'Amico low-risk prostate cancer including those who fulfilled Prostate Cancer Research International Active Surveillance (PRIAS) criteria, and to develop a tool for HGPGU prediction. HGPGU is a contraindication in most active surveillance (AS) and focal therapy protocols. PATIENTS AND METHODS In all, 10 616 patients with localised prostate cancer were treated at a high-volume European tertiary care centre from 2010 to 2015 with radical prostatectomy. Analyses were restricted to 1 819 patients with D'Amico low-risk prostate cancer (17.1%) with prostate-specific antigen (PSA) levels of <10.0 ng/mL, cT1c-cT2a and Gleason score ≤6, and were repeated within 772 of the men (7.3%) who fulfilled the PRIAS criteria for AS (PSA level of ≤10 ng/mL, T1c-T2, Gleason score ≤6, PSA density (PSAD) of <0.2 ng/mL2 , ≤2 positive cores). Uni- and multivariable logistic regression models were fitted, testing predictors of HGPGU. The final logistic regression model was based on the most informative variables. RESULTS There was HGPGU in 88 (4.8%) patients with D'Amico low-risk prostate cancer and in 32 (4.1%) of the subgroup who were PRIAS eligible. Multivariable analysis predicting HGPGU for the patients with D'Amico low-risk yielded three independent predictors: age, PSAD, and clinical tumour stage (P = 0.008, P = 0.005 and P = 0.021, respectively). Within the same patients, the model using all vs the most informative variables resulted in area under the curves (AUCs) of 69.2% and 68.3%, respectively. Multivariable analysis of those who were PRIAS eligible, yielded age and number of positive cores as independent predictors of HGPGU (P = 0.002 and P = 0.049, respectively; AUC 64.9%). CONCLUSIONS The low accuracy (invariably <70%) for HGPGU prediction in both patients with D'Amico low-risk prostate cancer and PRIAS eligibility indicates that these variables have poor predictive ability in contemporary patients. Despite HGPGU being a rare phenomenon, it may have life threatening implications and consequently alternatives such as biomarkers, genetic markers, or imaging modalities at re-biopsy are needed.

Abstract
Thymidylate synthase (TYMS) plays a role in DNA synthesis and is a target for 5-fluorouracil. In this study TYMS was analyzed by immunohistochemistry on a tissue microarray containing 11,152 prostate cancers. TYMS expression was higher in neoplastic than in normal prostate epithelium and was detectable in 72.9% of 10,223 interpretable cancers. It was considered strong in 21.9%, moderate in 33.4% and weak in 17.6% of tumors. TYMS overexpression was associated with deletions at 5q21 (p < 0.0001), 6q15 (p < 0.0001) and 3p13 (p = 0.0083) and gradually increased with the total number of these deletions present in the respective cancer sample (p < 0.0001). TYMS expression was unrelated to PTEN deletions (p = 0.9535) but tightly linked to high Gleason grade, advanced pathological tumor stage and early PSA recurrence (p < 0.0001). The prognostic value of TYMS was independent from the ERG status and deletions at 3p13, 5q21, and 6q15. In multivariate analyses the prognostic role of TYMS expression was independent of Gleason grade, pT stage, preoperative PSA, pN stage, or resection margins. TYMS expression analysis might result in clinically useful information in prostate cancer. The striking link to some but not all chromosomal aberrations might suggest a mechanistical link with specific types of DNA damage.

Abstract
HOXB13 is a prostate cancer susceptibility gene which shows a cancer predisposing (G84E) mutation in 0.1–0.6% of males. We analyzed the prognostic impact of HOXB13 expression by immunohistochemistry on a tissue microarray containing more than 12,400 prostate cancers. Results were compared to tumor phenotype, biochemical recurrence, androgen receptor (AR) and prostate specific antigen (PSA) as well as molecular subtypes defined by ERG status and genomic deletions of 3p, 5q, 6q, and PTEN. HOXB13 immunostaining was detectable in 51.7% of 10,216 interpretable cancers and considered strong in 9.6%, moderate in 19.7% and weak in 22.3% of cases. HOXB13 expression was linked to advanced pT stage, high Gleason grade, positive lymph node status (p < 0.0001 each), high pre-operative PSA levels (p = 0.01), TMPRSS2:ERG fusion, PTEN deletions, AR expression, cell proliferation, reduced PSA expression and early PSA recurrence (p < 0.0001 each). The prognostic value of HOXB13 was independent from established parameters including Gleason, stage, nodal stage and PSA. Co-expression analysis identified a subset of tumors with high HOXB13 and AR but low PSA expression that had a particularly poor prognosis. HOXB13 appears to be a promising candidate for clinical routine tests either alone or in combination with other markers, including AR and PSA.

Abstract
BACKGROUND Patients treated with robot-assisted radical prostatectomy (RARP) are frequently selected according to more favorable characteristics. Such patient selection might decrease according to increasing experience. METHODS We relied on the Martini Clinic Prostate Cancer Center database and focused on patients treated with RARP between 2004 and 2013. Differences in clinical, pathological and surgical characteristics at RARP over time (2004-2010, 2011-2012 and 2013) were assessed. RESULTS Overall, 1783 RARP patients were identified. Of those, 407 (22.8%), 764 (42.8%) and 612 (34.3%) were treated between 2004 and 2010, in 2011-2012 and in 2013, respectively. Unfavorable characteristics rate, such as biopsy Gleason Score ≥4+4 (8 vs. 9 vs. 15%, P<0.001), D'Amico high-risk (12 vs. 14 vs. 19%, P=0.001) and pathological Gleason score ≥4+4 (3 vs. 4 vs. 6%, P<0.001) increased over time. Pelvic lymph node dissection (PLND) was more frequently performed over time (62 vs. 83 vs. 84%, P<0.001), especially in D'Amico intermediate or high-risk patients (82 vs. 94 vs. 96%, P<0.001). Lymph node yield increased over time in overall (7 vs. 9 vs. 13, P<0.001), D'Amico intermediate (6 vs. 9 vs. 12, P<0.001) and D'Amico high-risk patients (9 vs. 12 vs. 18, P<0.001). No differences in surgical margin (P=0.7) and nerve sparing rates (P=0.09) were found. CONCLUSIONS A clear trend towards more unfavorable tumor characteristics over time was recorded. Additionally, the rates and extent of PLND increased with increasing experience. RAR P does not represent a barrier to PLND at our institution.

Abstract
BACKGROUND ELAVL1 is an RNA binding protein involved in translation control, which might have a regulatory role in prostate cancer progress. METHODS To evaluate its impact and relationship with key genomic alterations, ELAVL1 expression was analyzed by immunohistochemistry on a tissue microarray containing 12,427 prostate cancers. RESULTS The analysis revealed a mild to moderate predominantly nuclear immunostaining in normal prostate epithelium and an often higher both cytoplasmic and nuclear expression in cancer cells. Weak, moderate, and strong cytoplasmic ELAVL1 staining was found in 43%, 18%, and 3% of 10,478 interpretable tumors. Strong ELAVL1 staining was linked to high Gleason grade, advanced pathological tumor stage, positive nodal status, and PSA recurrence (P < 0.0001 each). A combined analysis of the effect of nuclear and cytoplasmic ELAVL1 expression on PSA recurrence revealed that the association with patient outcome was entirely driven by cytoplasmic staining. ELAVL1 positivity was more frequent in cancers harboring TMPRSS2:ERG fusions found by FISH (78%) or showing immunohistochemical ERG expression (74%) than in cancers without ERG rearrangement (63%) or ERG expression (58%, P < 0.0001 each). Strong cytoplasmic ELAVL1 staining was further linked to presence of PTEN, 5q21, 6q15, and 3p13 deletions (P < 0.0001 each), an observation consistent with cytoplasmic ELAVL1 accumulation in case of genomic instability. The prognostic role of ELAVL1 expression was independent of Gleason grade, T stage, N stage, surgical margin status, and preoperative PSA, irrespective of whether preoperative or postoperative variables were used for modeling. CONCLUSION Our study identifies cytoplasmic accumulation of ELAVL1 as a predictor of adverse clinical behavior of prostate cancer independent of established clinico-pathological parameters.

Abstract
PURPOSE Aberrant DNA content has been discussed as a potential prognostic feature in prostate cancer. EXPERIMENTAL DESIGN We analyzed the clinical significance of DNA ploidy in combination with prognostic relevant deletions of PTEN and 6q15 in 3,845 prostate cancers. RESULT The DNA status was diploid in 67.8%, tetraploid in 25.6%, and aneuploid in 6.8% of tumors, and deletions of PTEN and 6q15 occurred in 17.8% and 20.3% of tumors. Abnormal DNA content and deletions were linked to high Gleason score, advanced tumor stage, and positive nodal stage (P < 0.0001 each). The risk of PSA recurrence increased from diploid to tetraploid and from tetraploid to aneuploid DNA status (P < 0.0001 each). However, 40% of patients with Gleason score ≥4+4 and 55% of patients with PSA recurrence had diploid cancers. This fraction decreased to 21% (Gleason ≥4+4) and 29% (PSA recurrence) if PTEN and/or 6q deletion data were added to ploidy data to identify cancers with an aberrant DNA status. The significance of combining both deletions and ploidy was further demonstrated in a combined recurrence analysis. Presence of deletions increased the risk of PSA recurrence in diploid (P < 0.0001), tetraploid (P < 0.0001), and aneuploid cancers (P = 0.0049), and the combination of ploidy data and deletions provided clinically relevant information beyond the CAPRA-S nomogram. Multivariate modeling including preoperatively and postoperatively available parameters identified the "combined DNA status" as a strong independent predictor of poor patient outcome. CONCLUSIONS The combinatorial DNA content analysis involving general (ploidy) and specific events (deletions) has the potential for clinical utility in prostate cancer.

Abstract
INTRODUCTION The presence of circulating tumor cells (CTCs) is an established marker for prognosis in men with castration-resistant prostate cancer. A cutoff of ≥5 CTCs/7.5ml blood in the CellSearch Epithelial Cell Test has been shown to stratify prognostic groups and predict outcome of abiraterone treatment. In contrast, the value of CTC detection in men with localized prostrate cancer before radical prostatectomy (RP) is unknown. MATERIALS AND METHODS A total of 152 patients treated with RP between 06/2009 and 09/2009 were included. Peripheral venous blood drawn the day before RP was evaluated for CTCs by the CellSearch system. The detection of CTCs was correlated with prostate-specific antigen (PSA) and the histopathological outcome of the RP specimen. A cutoff of 0 vs. ≥1 CTC/7.5ml blood was defined as the threshold for positive vs. negative CTC status. RESULTS Median age was 62 years and median PSA was 6.7ng/dl. Staging revealed 62.5% pT2, 26.3% pT3a, and 11.2% pT3b tumors, and high-grade disease (≥Gleason 4+3) was determined in 25.6% of patients. CTCs were detected in 17 patients (11%) with a median CTC count/7.5ml of 1 (range: 1-clusters with>100 epithelial cells) without significant correlations to PSA levels, pT stage, or Gleason scores. Postoperative pT stage was a significant predictor of biochemical recurrence (BCR) in univariable logistic regression models and as a composite measure together with positive CTC counts (P<0.0001). CTC positivity alone tended to have a higher hazard ratio for BCR, but this was not statistically significant (P = 0.1). After a median follow-up of 48 months, there was no significant difference in BCR-free survival between patients with or without CTCs (P = 0.7). CONCLUSION Using the CellSearch system, we infrequently detected CTCs in patients with localized tumors before RP. The detection of CTCs did not correlate significantly with PSA, disease characteristics, or the development of BCR. However, larger cohorts with extended follow-up are needed to validate our findings.
