Abstract
INTRODUCTION Over the last decade, multiple clinical trials demonstrated improved survival after chemotherapy for metastatic prostate cancer (mPCa). However, real-world data validating this effect within large-scale epidemiological data sets are scarce. We addressed this void. MATERIALS AND METHODS Men with de novo mPCa were identified and systemic chemotherapy status was ascertained within the Surveillance, Epidemiology, and End Results database (2004-2016). Patients were divided between historical (2004-2013) versus contemporary (2014-2016). Chemotherapy rates were plotted over time. Kaplan-Meier plots and Cox regression models with additional multivariable adjustments addressed overall and cancer-specific mortality. All tests were repeated in propensity-matched analyses. RESULTS Overall, 19,913 patients had de novo mPCa between 2004 and 2016. Of those, 1838 patients received chemotherapy. Of 1838 chemotherapy-exposed patients, 903 were historical, whereas 905 were contemporary. Chemotherapy rates increased from 5% to 25% over time. Median overall survival was not reached in contemporary patients versus was 24 months in historical patients (hazard ratio [HR]: 0.55, p < 0.001). After propensity score matching and additional multivariable adjustment (age, prostate-specific antigen, GGG, cT-stage, cN-stage, cM-stage, and local treatment) a HR of 0.55 (p < 0.001) was recorded. Analyses were repeated for cancer-specific mortality after adjustment for other cause mortality in competing risks regression models and recorded virtually the same findings before and after propensity score matching (HR: 0.55, p < 0.001). CONCLUSIONS In mPCa patients, chemotherapy rates increased over time. A concomitant increase in survival was also recorded.

Abstract
The evolution in the past decade of recommendations for prostate cancer (PCa) management, from screening to surgical treatment, may have affected the radical prostatectomy (RP) landscape. However, comprehensive data at a national level remain scarce. We extracted 5-yr data for RP patients in France from the central database of the national health care system. The primary endpoints were surgical approach (open [ORP], laparoscopic [LRP], and robot-assisted RP [RARP]), length of stay (LOS), and complication and readmission rates. The annual number of RPs was stable during the study period. The proportion of RARPs increased from 39.8% in 2015 to 52.6% in 2019, whereas the proportion of ORPs decreased from 34.4% to 24.5%. LOS continuously decreased over time irrespective of the surgical approach. The proportion of centres in the highest quartile of hospital volume increased from 22.0% to 28.3% (p = 0.006). LOS and complication and readmission rates were significantly lower (p < 0.001) in the LRP cohort at each time point. National trends confirmed that RARP progressively replaced ORP, with a stable number of annual RPs over time. Greater centralisation and better early postoperative outcomes were observed with laparoscopy. Patient summary We reviewed French data for patients undergoing removal of the prostate for prostate cancer between 2015 and 2019. We found that robot-assisted minimally invasive surgery has increased over time and the length of hospital stays has decreased. Rates of complications and readmission were lower with minimally invasive surgery.

Changing trends in robot-assisted radical prostatectomy: Inverse stage migration-A retrospective analysis. Prostate Int 2021; 9:157-162. [PMID: 34692589 PMCID: PMC8498691 DOI: 10.1016/j.prnil.2021.04.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 03/30/2021] [Accepted: 04/08/2021] [Indexed: 11/23/2022] Open
Abstract
Background With increasing availability of data on outcomes of surgery for prostate cancer, the profile of patients undergoing robot-assisted radical prostatectomy (RARP) has changed over the past decade. This impacts the decision-making process for surgeons and patients, particularly in low-incidence regions of Asia. Our institution was among the first in Asia to acquire a da Vinci surgical robot in 2005. We evaluated the changes in the clinical and pathology profile of patients undergoing RARP at our institution over the past 15 years (2005-2019). Methods A retrospective analysis of patients undergoing RARP between April 2005 and December 2019 was conducted from the hospital database. The patients were divided into two groups; patients undergoing RARP from April 2005 to December 2012 (Group I, first 8 years) and January 2013 to December 2019 (Group II, next 7 years). The perioperative characteristics were compared between these two groups to assess changes in their profile and outcome. Results Four hundred forty-seven patients were included in this study; 244 (54.6%) in Group I and 203 (45.4%) in Group II. The median prostate specific antigen in Group II was significantly higher than that in Group I (14.5 vs. 11.7 ng/ml, P = 0.016). Unfavorable pathological characteristics, i.e., Gleason Grade ≥3, perineural invasion, and the margin positivity rate increased substantially from 18.5% to 37.5%, 20.5% to 36.9%, and 15.2% to 26.6%, respectively, in Group II compared with Group I. More patients in Group II received adjuvant therapy than in Group I (P < 0.001). Conclusion There has been a change in profile of patients undergoing RARP and patients with more unfavorable disease characteristics such as higher prostate specific antigen and tumor grade are undergoing surgery. In line with international trends, the number of patients with low-grade disease undergoing surgery has substantially decreased. Multimodal treatment with adjuvant therapy is increasingly used, particularly in high-risk disease.

Twenty-year trends in prostate cancer stage and grade migration in a large contemporary german radical prostatectomy cohort. Prostate 2021; 81:849-856. [PMID: 34110033 DOI: 10.1002/pros.24181] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 05/08/2021] [Accepted: 06/01/2021] [Indexed: 11/11/2022]
Abstract
BACKGROUND A trend towards inverse stage migration in prostate cancer (PCa) was reported. However, previous analyses did not take into account potential differences in sampling strategies (number of biopsy cores), which might have confounded these reports. MATERIAL AND METHODS Within our single-institutional database we identified PCa patients treated with radical prostatectomy (RP) between 2000 and 2020 (n = 21,646). We calculated the estimated annual percentage change (EAPC) for D'Amico risk groups, biopsy Gleason Grade Group (GGG), PSA and cT stage as well as postoperative RP GGG and pT stage relying on log linear regression methodology. Subsequently, we repeated the analyses after adjustment for number of cores obtained at biopsy. RESULTS Absolute rates of D'Amico low risk decreased (-30.1%), while intermediate and high risk increased (+21.2% and +9.0%, respectively). Rates of GGG I decreased (-50.0%), while GGG II-V increased, with the largest increase in GGG II (+22.5%). This trend, albeit less pronounced, was also recorded after adjusted EAPC analyses (p < .05). Specifically, EAPC values for D'Amico low vs intermediate vs high risk were -1.07%, +0.37%, +0.45%, respectively, and EAPC values for GGG ranged between -0.71% (GGG I) and +0.80% (GGG IV). Finally, an increase in ≥cT2 (EAPC: +3.16%) was displayed (all p < .001). These trends were confirmed in EAPC calculations in RP GGG and pT stages (p < .001). CONCLUSION Our findings confirm the trend towards less frequent treatment of low risk PCa and more frequent treatment of high risk PCa, also after adjustment for number of biopsy cores.

Abstract
BACKGROUND Recently, an increase in the rates of high-risk prostate cancer (PCa) was reported. We tested whether the rates of and low, intermediate, high and very high-risk PCa changed over time. We also tested whether the number of prostate biopsy cores contributed to changes rates over time. METHODS Within the Surveillance, Epidemiology and End Results (SEER) database (2010-2015), annual rates of low, intermediate, high-risk according to traditional National Comprehensive Cancer Network (NCCN) and high versus very high-risk PCa according to Johns Hopkins classification were tabulated without and with adjustment for the number of prostate biopsy cores. RESULTS In 119,574 eligible prostate cancer patients, the rates of NCCN low, intermediate, and high-risk PCa were, respectively, 29.7%, 47.8%, and 22.5%. Of high-risk patients, 39.6% and 60.4% fulfilled high and very high-risk criteria. Without adjustment for number of prostate biopsy cores, the estimated annual percentage changes (EAPC) for low, intermediate, high and very high-risk were respectively -5.5% (32.4%-24.9%, p < .01), +0.5% (47.6%-48.4%, p = .09), +4.1% (8.2%-9.9%, p < .01), and +8.9% (11.8%-16.9%, p < .01), between 2010 and 2015. After adjustment for number of prostate biopsy cores, differences in rates over time disappeared and ranged from 29.8%-29.7% for low risk, 47.9%-47.9% for intermediate risk, 8.9%-9.0% for high-risk, and 13.6%-13.6% for very high-risk PCa (all p > .05). CONCLUSIONS The rates of high and very high-risk PCa are strongly associated with the number of prostate biopsy cores, that in turn may be driven by broader use magnetic resonance imaging (MRI).

Abstract
OBJECTIVE To determine the feasibility and outcome of radical prostatectomy (RP) following neoadjuvant therapy (NAT) in patients with initial inoperable, rectum-infiltrating cT4 prostate cancer (PCa). METHODS From 01/2018 to 12/2020, 26 patients with clinical (DRE) or radiographical (mpMRI) suspicion of rectum infiltrating PCa at diagnosis and NAT prior to RP were retrospectively identified from our prospective institutional database. Two patients were still inoperable after NAT. Downsizing was administered for at least 20 weeks and RP was performed after excluding ongoing rectal infiltration. RESULTS At diagnosis, median PSA was 42.5 ng/ml (IQR: 23.0-66.1). Inductive NAT consisted of androgen deprivation therapy (ADT) in combination with chemotherapy (n = 9) or without chemotherapy (n = 14). Median preoperative PSA was 0.93 ng/ml (IQR: 0.24-0.40). Median time from NAT to RP was 6 months (IQR: 5-7). Two patients were still inoperable after NAT. Of 24 patients undergoing RP, abortion of surgery due to inoperability was observed in 2 patients (8.4%), demonstrating a total failure rate of NAT in 4 out of 26 patients (15.4%). One patient suffered a rectal injury with consecutive colostomy (4.2%). No Clavien-Dindo complication Grade IV or V were observed. Urinary continence was achieved in 16 patients (84.2%). Sufficient erection for sexual intercourse was present in 2 patients (10.5%). All patients received adjuvant ADT with or without radiation therapy. Median PSA at 13 months was 0.08 ng/ml (IQR: 0.01-0.74). CONCLUSION RP of initially rectum infiltrating PCa is feasible and safe after inductive NAT, however complications rates tend to be higher compared to standard RP.

Abstract
CLINICAL/METHODOLOGICAL ISSUE Multiparametric magnetic resonance imaging (mpMRI) of the prostate plays a crucial role in the diagnosis and local staging of primary prostate cancer. STANDARD RADIOLOGICAL METHODS Image-guided biopsy techniques such as MRI-ultrasound fusion not only allow guidance for targeted tissue sampling of index lesions for diagnostic confirmation, but also improve the detection of clinically significant prostate cancer. METHODOLOGICAL INNOVATIONS Minimally invasive, focal therapies of localized prostate cancer complement the treatment spectrum, especially for low- and intermediate-risk patients. PERFORMANCE In patients of low and intermediate risk, MR-guided, minimally invasive therapies could enable local tumor control, improved functional outcomes and possible subsequent therapy escalation. Further study results related to multimodal approaches and the application of artificial intelligence (AI) by machine and deep learning algorithms will help to leverage the full potential of focal therapies for prostate cancer in the upcoming era of precision medicine. ACHIEVEMENTS Completion of ongoing randomized trials comparing each minimally invasive therapy approach with established whole-gland procedures is needed before minimally invasive therapies can be implemented into existing treatment guidelines. PRACTICAL RECOMMENDATIONS This review article highlights minimally invasive therapies of prostate cancer and the key role of mpMRI for planning and conducting these therapies.

Abstract
INTRODUCTION Long-term outcomes of prostate cancer (CaP) patients treated with radical prostatectomy (RP) from European cohorts are under-reported. We report on 22,843 RP patients from the Martini-Klinik Prostate Cancer Centre treated between 1992 and 2017. PATIENTS AND METHODS Biochemical recurrence (BCR) free survival, metastasis free survival (MFS), and cancer specific survival (CSS) were stratified according to National Comprehensive Cancer Network (NCCN) risk categories, pT, and pN stages, RP Gleason Grade Groups (GGG), and surgical margin status (R0/R1). For time to event analyses, uni- and multivariable Cox's proportional hazards models and univariable Kaplan-Meier analyses were applied. RESULTS Median follow up was 68 months. Most favourable 20-year survival rates were exhibited in NCCN low risk (78.7% BCR-free, 96.8% MFS, 90.1% CSS) and pT2, GGG 1 to 2, R0 patients (83.1% BCR-free, 96.7% MFS, 92.6% CSS). 20-year follow up was not constantly reached in patients with aggressive CaP features. For example, NCCN very high-risk patients exhibited 15-year BCR-free survival of 30.5%, while 20-year MFS and CSS in these individuals was reached (64.1% and 60.8%, respectively). Lowest 10-year BCR-free survival (35.6%) was exhibited in pT3b, GGG 4 to 5, R0. Lowest 10-year MFS (49.5%) was exhibited in pT2, GGG 4 to 5, R1. Lowest 10-year CSS (69.8%) was exhibited in pT3b, GGG 4 to 5, R1 patients. In separate pN1 analyses, lowest 10-year BCR-free survival (14.5%), MFS (56.9%), and CSS (71.9%) were exhibited in patients with 3 or more positive lymph nodes. CONCLUSION Oncological outcomes after RP can be excellent for individuals with favorable CaP characteristics, also after 20 years of follow up.

External Validation of the Briganti Nomogram to Predict Lymph Node Invasion in Prostate Cancer-Setting a New Threshold Value. Life (Basel) 2021; 11:life11060479. [PMID: 34070313 PMCID: PMC8227656 DOI: 10.3390/life11060479] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 05/20/2021] [Accepted: 05/24/2021] [Indexed: 12/26/2022] Open
Abstract
(1) Introduction: The study aimed to test and validate the performance of the 2012 Briganti nomogram as a predictor for pelvic lymph node invasion (LNI) in men who underwent radical prostatectomy (RP) with extended pelvic lymph node dissection (PLND) to examine their performance and to analyse the therapeutic impact of using a different nomogram cut-off. (2) Material and Methods: The study group consisted of 222 men with clinically localized prostate cancer (PCa) who underwent RP with ePLND between 01/2012 and 10/2018. Measurements included: preoperative PSA, clinical stage (CS), primary and secondary biopsy Gleason pattern, and the percentage of positive cores. The area under the curve (AUC) of the receiver operator characteristic analysis was appointed to quantify the accuracy of the primary nomogram model to predict LNI. The extent of estimation associated with the use of this model was graphically depicted using calibration plots. (3) Results: The median number of removed lymph nodes was 16 (IQR 12–21). A total of 53 of 222 patients (23.9%) had LNI. Preoperative clinical and biopsy characteristics differed significantly (all p < 0.005) between men with and without LNI. A nomogram-derived cut-off of 7% could lead to a reduction of 43% (95/222) of lymph node dissection while omitting 19% (10/53) of patients with LNI. The sensitivity, specificity, and negative predictive value associated with the 7% cut-off were 81.1%, 50.3%, and 96.3%, respectively. (4) Conclusions: The analysed nomogram demonstrated high accuracy for LNI prediction. A nomogram-derived cut-off of 7% confirmed good performance characteristics within the first external validation cohort from Poland.

Abstract
Purpose: To assess the diagnostic performance of the tumor contact length (TCL) and apparent diffusion coefficient (ADC) for predicting extraprostatic extension (EPE) of prostate cancer with capsular abutment (CA). Methods: Ninety-three patients with biopsy-proven prostate cancer underwent 3-Tesla MRI, including diffusion-weighted imaging (b value = 0, 2000 s/mm2) and radical prostatectomy. Two experienced radiologists, blinded to the clinicopathological data, retrospectively assessed the presence of CA on T2-weighted imaging (T2WI). TCL on T2WI and ADC values were measured on detecting CA in prostate cancer. We used the receiver operating characteristic curves to assess the diagnostic performance of TCL and ADC values for predicting EPE. Results: CA was present in 58 prostate cancers among 93 patients. The cut-off value for TCL was 6.9 mm, which yielded an area under the curve (AUC) of 0.75. This corresponded to a sensitivity, specificity, and accuracy of 84.2%, 61.5%, and 69.0%, respectively. The cut-off value for ADC was 0.63 × 10–3 mm2/s, which yielded an AUC of 0.76. This, in turn, corresponded to a sensitivity, specificity, and accuracy of 84.2%, 59.0%, and 67.2%, respectively. The combined cut-off value of TCL and ADC yielded an AUC of 0.82. The specificity (84.6%) and accuracy (81.0%) of the combined value were superior to their individual values (P < 0.05). Conclusion: A combination of TCL and ADC values provided high specificity and accuracy for detecting EPE of prostatic cancer with CA.

Abstract
Objective: To investigate temporal trends in prostate cancer (PCa) radical prostatectomy (RP) candidates. Materials and Methods: Patients who underwent RP for PCa between January 2014 and December 2019 were identified form our institutional database. Trend analysis and logistic regression models assessed RP trends after stratification of PCa patients according to D'Amico classification and Gleason score. Patients with neoadjuvant androgen deprivation or radiotherapy prior to RP were excluded from the analysis. Results: Overall, 528 PCa patients that underwent RP were identified. Temporal trend analysis revealed a significant decrease in low-risk PCa patients from 17 to 9% (EAPC: -14.6%, p < 0.05) and GS6 PCa patients from 30 to 14% (EAPC: -17.6%, p < 0.01). This remained significant even after multivariable adjustment [low-risk PCa: (OR): 0.85, p < 0.05 and GS6 PCa: (OR): 0.79, p < 0.001]. Furthermore, a trend toward a higher proportion of intermediate-risk PCa undergoing RP was recorded. Conclusion: Our results confirm that inverse stage migration represents an ongoing phenomenon in a contemporary RP cohort in a European tertiary care PCa center. Our results demonstrate a significant decrease in the proportion of low-risk and GS6 PCa undergoing RP and a trend toward a higher proportion of intermediate-risk PCa patients undergoing RP. This indicates a more precise patient selection when it comes to selecting suitable candidates for definite surgical treatment with RP.

Abstract
In 2019, the American Cancer Society (ACS) estimates that 174,650 new cases of prostate cancer will be diagnosed and 31,620 will die due to the prostate cancer in the United States. Prostate cancer is often managed with aggressive curative intent standard therapies including radiotherapy or surgery. Regardless of how expertly done, these standard therapies often bring significant risk and morbidity to the patient's quality of life with potential impact on sexual, urinary, and bowel functions. Additionally, improved screening programs, using prostatic-specific antigen and transrectal ultrasound-guided systematic biopsy, have identified increasing numbers of low-risk, low-grade "localized" prostate cancer. The potential, localized, and indolent nature of many prostate cancers presents a difficult decision of when to intervene, especially within the context of the possible comorbidities of aggressive standard treatments. Active surveillance has been increasingly instituted to balance cancer control versus treatment side effects; however, many patients are not comfortable with this option. Although active debate continues on the suitability of either focal or regional therapy for the low- or intermediate-risk prostate cancer patients, no large consensus has been achieved on the adequate management approach. Some of the largest unresolved issues are prostate cancer multifocality, limitations of current biopsy strategies, suboptimal staging by accepted imaging modalities, less than robust prediction models for indolent prostate cancers, and safety and efficiency of the established curative therapies following focal therapy for prostate cancer. In spite of these restrictions, focal therapy continues to confront the current paradigm of therapy for low- and even intermediate-risk disease. It has been proposed that early detection and proper characterization may play a role in preventing the development of metastatic disease. There is level-1 evidence supporting detection and subsequent aggressive treatment of intermediate- and high-risk prostate cancer. Therefore, accurate assessment of cancer risk (i.e., grade and stage) using imaging and targeted biopsy is critical. Advances in prostate imaging with MRI and PET are changing the workup for these patients, and advances in MR-guided biopsy and therapy are propelling prostate treatment solutions forward faster than ever.

Abstract
The majority of patients with prostate cancer who later develop lethal metastatic disease have high-risk localized disease at presentation, emphasizing the importance of effective treatment strategies at this stage. Multimodal treatment approaches that combine systemic and local therapies offer a promising strategy for improving the clinical outcomes of patients with high-risk localized prostate cancer. Combinations of neoadjuvant and adjuvant chemotherapy, hormonal therapy, or chemohormonal therapy are considered to be the standard of care in most solid tumours and should be investigated in the future for the treatment of prostate cancer to improve patient outcomes. However, although the combination of androgen deprivation therapy and radiotherapy is a standard of care in high-risk localized or locally advanced prostate cancer, the benefit of chemotherapy or chemohormonal therapy has yet to be demonstrated outside of the metastatic setting. Moreover, the benefit of neoadjuvant and/or adjuvant systemic therapies in combination with radical prostatectomy has not been proved. The development of next-generation hormonal agents, which have been approved for the treatment of castration-resistant prostate cancer, offers further therapeutic possibilities that are being assessed in early-phase clinical trials.

Abstract
OBJECTIVE There is controversy around prostate cancer (PCa) screening through the use of PSA, due to the risk of overtreatment. The current trend observed in various European and American studies is a decrease in the number of radical prostatectomy (RP) in low-risk PCa and an increase for intermediate or locally advanced diseases. The objective of this study was to observe the migration of the pathological stages from radical prostatectomy (RP) over 10 years in France through 2 French centers. METHODS It was a multicentric retrospective study, where all the RP realized in 2 French tertiary centers, in a laparoscopic or retropubic approach for each of the years 2005, 2010 and 2015 were included. Preoperative data (age, PSA, clinical stage, number of positive biopsies, Gleason biopsy score) and postoperative data (pTNM, pathological Gleason score (pGS)) were analyzed and compared. RESULTS In all, 1282 RP were realized (503 in 2005, 403 in 2010, 376 in 2015). Respectively between 2005, 2010, 2015 the average number of positive biopsy increased significantly from 2.30 vs. 2.88 vs. 5.3 (P=0.0001). The distribution of D'Amico's risk evolves with time: low-risk: 49.9 vs. 44.4 vs. 15.7% (P=0.0001); intermediate risk: 40.95 vs. 43.92 vs. 64.1% (P=0.0001) and high-risk: 9.15 vs. 11.66 vs. 20.2% (P=0.0001) between 2005, 2010 and 2015 respectively. pGS evolved to higher score with SG<7: 22.8 vs. 29.9 vs. 7.1% et SG≥7: 77.2 vs. 70.1 vs. 92.9% (P=0.001). Also, pTNM increased to non-organ-confined disease: pT2: 66.9 vs. 51.9 vs. 48.7%; pT3: 33.1 vs. 48.1 vs. 51.3% (P=0.0001). CONCLUSION This study showed a change in the management of PCa since new recommendations from medical authorities about PSA screening and evolving of conservative treatment. Number of RP increase for higher risk PCa. This change corresponds to better patient selection for RP: decrease for low-risk and increase for high-risk organ-confined disease. LEVEL OF EVIDENCE 3.

Abstract
Prostate cancer is the most commonly diagnosed noncutaneous cancer and second leading cause of death in men. Many patients with clinically organ-confined prostate cancer undergo definitive treatment of the whole gland, including radical prostatectomy, radiation therapy, and cryosurgery. Active surveillance is a growing alternative option for patients with documented low-volume and low-grade prostate cancer. However, many patients are wanting a less morbid focal treatment alternative. With recent advances in software and hardware of magnetic resonance imaging (MRI), multiparametric MRI of the prostate has been shown to improve the accuracy in detecting and characterizing clinically significant prostate cancer. Targeted biopsy is increasingly utilized to improve the yield of MR detected, clinically significant prostate cancer and to decrease in detection of indolent prostate cancer. MR-guided targeted biopsy techniques include cognitive MR fusion transrectal ultrasound (TRUS) biopsy, in-bore transrectal targeted biopsy using robotic transrectal device, and in-bore direct MR-guided transperineal biopsy with a software based transperineal grid template. In addition, advances in MR-compatible thermal ablation technology allow accurate focal or regional delivery of thermal ablative energy to the biopsy-proved, MRI-detected tumor. MR-guided ablative treatment options include cryoablation, laser ablation, and high-intensity focused ultrasound with real-time or near simultaneous monitoring of the ablation zone. We present a contemporary review of MR-guided techniques for prostatic interventions.

Abstract
PURPOSE OF REVIEW Although cytoreductive surgery is accompanied with prolonged survival in many other malignancies in a metastatic stage, its role in oligometastatic prostate cancer is unclear. RECENT FINDINGS Radical prostatectomy (RP) in patients with oligometastatic prostate cancer seems to be feasible. Perioperative complication rates vary between 20 and 50% (Clavien 1-3) and are comparable to patients with locally advanced tumors. Postoperative functional outcomes (urinary continence and erectile function) can be slightly worse than in patients with locally advanced tumor. In literature, an oncological benefit of surgery is so far only described for retrospective multiinstitutional databases and a case-control study but not for prospective studies. Still, men undergoing RP clearly seem to develop severe local complications less frequently than patients receiving best systemic therapy (up to more than 50% versus less than10%). SUMMARY Patients should be counseled about the potential significant reduction of local complications whenever undergoing RP for oligometastatic prostate cancer. Nevertheless, as complication rates are relatively high, functional outcome can be slightly worse compared with RP with curative intent and especially as oncological benefit so far is shown using retrospective but not prospective data, patients should only undergo surgery within the ongoing prospective, randomized trials.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 67-year-old man had presented to his primary physician for routine health maintenance. A digital rectal examination was performed and revealed a suspicious nodule in the right lobe of the prostate without any extraprostatic extension. A serum prostate-specific antigen (PSA) test was 12.4 ng/mL. He had no previous PSA tests. Transrectal ultrasound-guided prostate biopsy showed Gleason 3 + 4 prostate adenocarcinoma in seven of 12 cores. Bone scan and computed tomography scan of the pelvis showed no evidence of metastatic disease, and the patient underwent a robotic-assisted radical prostatectomy with bilateral pelvic lymphadenectomy. Pathology revealed Gleason 3 + 4 adenocarcinoma bilaterally, with extracapsular extension, no seminal vesicle invasion, a 2-mm positive margin at the right mid gland, and 0 of 15 lymph nodes containing adenocarcinoma. Two months after surgery, he had mild stress urinary incontinence and PSA of < 0.1 ng/mL. Adjuvant radiotherapy was discussed, but he elected to have careful follow-up. His PSA was monitored every 6 months and gradually increased from < 0.1 ng/mL to 0.4 ng/mL over the next 3 years. He was asymptomatic. He was referred to discuss the role of salvage radiotherapy.

Focal treatment of prostate cancer has evolved from a concept to a practice in the recent few years and is projected to fill an existing need, bridging the gap between conservative and radical traditional treatment options. With its low morbidity and rapid recovery time compared with whole-gland treatment alternatives, focal therapy is poised to gain more acceptance among patients and health care providers. As our experience with focal treatment matures and evidence continues to accrue, the landscape of this practice might look quite different in the future.

Abstract
BACKGROUND Due to an inverse stage migration, the proportion of patients with more aggressive and locally advanced prostate cancer (PCa) has increased over the last few years. The natural history in these patients shows a higher risk of local complications and worse oncologic outcome. OBJECTIVES To analyze the impact of radical prostatectomy (RP) in patients with locally advanced PCa. MATERIALS AND METHODS A review of the literature was performed using PubMed and MEDLINE databases focusing on articles addressing locally advanced PCa. RESULTS Current guidelines recommend local therapy in patients with locally advanced PCa among other treatment options. Thereby no strong evidence favoring radiotherapy or RP is present. Compared to patients without local treatment, RP may improve oncologic outcome and decrease the risk of local complications. Due to more difficult surgery and an increased need of multimodal therapy, higher perioperative morbidity and worse functional outcomes compared to patients with localized PCa are reported. No reliable prospective data indicating a widespread use of neoadjuvant treatment exists. Indication for further adjuvant or salvage therapies depends on pathologic results and postoperative course. CONCLUSIONS RP is one of the treatment options with good long-term results which can be offered to patients with locally advanced PCa. Nevertheless, patients need to be counselled especially about the worse postoperative functional outcome compared to patients with localized PCa.

Abstract
OBJECTIVE To establish an external validation of the new nomogram from Gandaglia et al which provides estimates of the probability of pathological favorable disease in pre-operatively defined intermediate-risk PCa. PATIENTS AND METHODS Overall, 2928 intermediate-risk PCa patients according to the D'Amico classification undergoing RP and bilateral lymph node dissection in seven academic centres between 2000 and 2011. Pathologically favorable PCa was defined as low-grade organ-confined disease. The Receiver Operating Characteristic (ROC) curve was obtained to quantify the overall accuracy (Area Under the Curve, AUC) of the model to predict specimen-confined (SC) disease. Calibration curve was then constructed to illustrate the relationship between the risk-estimates obtained by the model and the observed proportion of SC disease. Kaplan-Meier method was used for PSA recurrence-free survival (PSA-RFS) assessment. RESULTS Median age was 68 years. 10.6% patients finally presented pathologically favorable disease characteristics at RP. A higher PSAD (OR = 0.01; 95%CI = 0.00-0.04; P < 0.0001) and percentage of positive cores (OR = 0.97; 95%CI = 0.96-0.98; P < 0.0001) were associated with a reduced probability of favorable disease at RP in multivariate analysis. ROC curve analysis showed strongest accuracy of the model (AUC = 0.82; 95%CI = 0.79-0.84). Favorable PCa had a significantly better PSA recurrence-free survival rates as compared to unfavorable PCa after RP (94.2% vs 74.4% at 4 years, P < 0.0001). CONCLUSIONS This external validation of the Gandaglia nomogram shows relevant accuracy with one out of ten patients in this intermediate risk PCa group with pathologically proven organ-confined disease. This validated risk calculator can help physician to distinguish favorable intermediate risk PCa that can be treated by conservative approach or safer nerve-sparing surgery.

Abstract
Introduction The objective of this study was to evaluate changes of patient characteristics and
surgical techniques in radical prostatectomy in Germany within the last decade. Methods Data from 44 German prostate cancer centers were included in the study. Patients’ characteristics (age, initial PSA value), surgical techniques (open vs. minimally invasive approaches), perioperative parameters (operating time, rate of nerve-sparing (NS) radical prostatectomies (RPs), hospitalization time, catheter indwelling time, surgical margin status, number of dissected lymph nodes (LN)), and pathological findings (tumor stage, Gleason score) were analyzed. Results Data from 11,675 patients who underwent RP between 2005 and 2014 were analyzed. The rate of open RP approaches decreased by 1.7% (p = 0.0164), the rate of minimally invasive approaches increased by 1.8% (p = 0.0164). Robot-assisted RPs (RARP) increased by 4.6% (p < 0.0001). The number of NS procedures and pelvic lymphadenectomy (LA) increased by 4.5% (p < 0.0001) and 4.7% (p < 0.0001), respectively. Catheter indwelling time and hospitalization time decreased by 1 day (p < 0.0001). No change in the rate of positive surgical margins (p = 0.5061) and the ratio of positive lymph nodes removed (p = 0.4628) was observed. The number of Gleason ≤6 tumors decreased significantly (p < 0.0001). Conclusions The number of RARP has significantly increased over the past decade and there is a trend towards surgeries on more advanced tumors with higher yields of lymph nodes dissected. At the same time, the rate of nerve-sparing procedures has significantly increased.

Abstract
OBJECTIVE To externally validate the updated 2012 Partin Tables in contemporary North American patients treated with radical prostatectomy (RP) for localized prostate cancer (PCa) at community institutions. MATERIALS AND METHODS We examined records of 25,254 patients treated with RP and pelvic lymph node dissection (PLND) between 2010 and 2013, within the surveillance, epidemiology, and end results database. The ROC derived AUC assessed discriminant properties of the updated 2012 Partin Tables of organ confined disease (OC), extracapsular extension (ECE), seminal vesical invasion (SVI), and lymph node invasion (LNI). Calibration plots focused on calibration between predicted and observed rates. RESULTS Proportions of OC, ECE, SVI, and LNI at RP were 69.8%, 18.4%, 7.4%, and 4.4%, respectively. Accuracy for prediction of OC, ECE, SVI, and LNI was 70.4%, 59.9%, 72.9%, and 77.1%, respectively. In subgroup analyses in patients with nodal yield >10, accuracy for LNI prediction was 76.0%. Subgroup analyses in elderly patients and in African American patients revealed decreased accuracy for prediction of all four endpoints. Last but not least, SVI and LNI calibration plots showed excellent agreement, versus good agreement for OC (maximum underestimation of 10%) and poor agreement for ECE (maximum overestimation of 12%). CONCLUSION Taken together, the updated 2012 Partin Tables can be unequivocally endorsed for prediction of OC, SVI, and LNI in community-based patients with localized PCa. Conversely, ECE predictions failed to reach the minimum accuracy requirements of 70%. Prostate 77:105-113, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
PURPOSE The purpose of this study was to compare the PI-RADS V2 scores, ADC histogram-derived parameters, and their combination for the diagnosis of clinically significant peripheral zone prostate cancer (PCa). MATERIALS AND METHODS The IRB approved this retrospective study of 47 men who underwent 1.5 Tesla endorectal prostate magnetic resonance imaging (MRI). Informed consent was waived. Two readers identified and scored MRI lesions using PI-RADS V2. Their mean, median, 10th, 25th, 75th percentile ADC values, and normalized ratio were also calculated. Multilevel logistic regression and receiver-operating characteristic (ROC) curve analyses assessed their diagnostic performance. Clinically significant PCa was defined as tumor volume over 0.5 cc and Gleason grade of 4 or 5 on prostatectomy. RESULTS The area under the ROC curve (A z) of the overall and diffusion-weighted imaging (DWI) PI-RADS V2 scores were 0.69 and 0.84 (reader-1), and 0.68 and 0.73 (reader-2). The A z of ADC parameters ranged from 0.68 to 0.75 for both readers. Compared to other predictors, DWI PI-RADS V2 yielded the highest A z for identification of significant cancer; but, except for reader-1 75th percentile ADC, the differences were not statistically significant (P > 0.05). Adding ADC parameters to PI-RADS V2 scores did not improve their diagnostic ability. CONCLUSION DWI PI-RADS V2 score may a better predictor of clinically significant PCa than the overall PI-RADS V2 score, but its diagnostic performance was not significantly improved by the addition of objective ADC value measurements.

Abstract
Prostate cancer is the most common cancer (other than skin cancer) in American men, with one in seven men being diagnosed with this disease during his lifetime. The estimated number of new prostate cancer cases in 2016 is 180,890. For the first time, imaging has become the center of the search for contained, intraglandular, small-volume, and unifocal disease, and an increasing number of academic institutions as well as private practices are implementing programs for prostate multiplanar magnetic resonance imaging (MRI) as parts of their routine offerings. This article reviews the role of MRI-guided focal prostate ablation, as well as opportunities for further growth in this minimally invasive therapy of prostate cancer.

Abstract
OBJECTIVE To update the Partin Tables for prediction of pathological stage in the contemporary setting and examine trends in patients treated with radical prostatectomy (RP) over the past three decades. PATIENTS AND METHODS From January 2010 to October 2015, 4459 men meeting inclusion criteria underwent RP and pelvic lymphadenectomy for histologically confirmed prostate cancer at the Johns Hopkins Hospital. Preoperative clinical stage, serum prostate-specific antigen (PSA) level, and biopsy Gleason score (i.e. prognostic Grade Group) were used in a polychotomous logistic regression model to predict the probability of pathological outcomes categorised as: organ-confined (OC), extraprostatic extension (EPE), seminal vesicle involvement (SV+), or lymph node involvement (LN+). Preoperative characteristics and pathological findings in men treated with RP since 1983 were collected and clinical-pathological trends were described. RESULTS The median (range) age at surgery was 60 (34-77) years and the median (range) PSA level was 4.9 (0.1-125.0) ng/mL. The observed probabilities of pathological outcomes were: OC disease in 74%, EPE in 20%, SV+ in 4%, and LN+ in 2%. The probability of EPE increased substantially when biopsy Gleason score increased from 6 (Grade Group 1, GG1) to 3 + 4 (GG2), with smaller increases for higher grades. The probability of LN+ was substantially higher for biopsy Gleason score 9-10 (GG5) as compared to lower Gleason scores. Area under the receiver operating characteristic curves for binary logistic models predicting EPE, SV+, and LN+ vs OC were 0.724, 0.856, and 0.918, respectively. The proportion of men treated with biopsy Gleason score ≤6 cancer (GG1) was 47%, representing a substantial decrease from 63% in the previous cohort and 77% in 2000-2005. The proportion of men with OC cancer has remained similar during that time, equalling 73-74% overall. The proportions of men with SV+ (4.1% from 3.4%) and LN+ (2.3% from 1.4%) increased relative to the preceding era for the first time since the Partin Tables were introduced in 1993. CONCLUSIONS The Partin Tables remain a straightforward and accurate approach for projecting pathological outcomes based on readily available clinical data. Acknowledging these data are derived from a tertiary care referral centre, the proportion of men with OC disease has remained stable since 2000, despite a substantial decline in the proportion of men with biopsy Gleason score 6 (GG1). This is consistent with the notion that many men with Gleason score 6 (GG1) disease were over treated in previous eras.

Abstract
PURPOSE Some patients with long postoperative intervals of undetectable prostate specific antigen are still at risk for biochemical recurrence. Our aims were to identify prognostic factors for late biochemical recurrence, including cancer family history, and evaluate cancer specific mortality. MATERIALS AND METHODS We identified 10,310 patients after radical prostatectomy without neoadjuvant or adjuvant therapy between 1979 and 2015 in the prospective German Familial Prostate Cancer database. A subgroup of 2,480 patients with more than 10 years of followup (median 12.8) had undetectable prostate specific antigen. Biochemical recurrence, defined as prostate specific antigen 0.2 ng/ml or greater, developing at more than 10 years was defined as late biochemical recurrence. Multiple proportional hazards regression with forward selection was applied to determine prognostic factors for late biochemical recurrence. RESULTS The Kaplan-Meier estimated biochemical recurrence rate at 10, 15 and 20 years was 34.3%, 44.0% and 52.7%, respectively. Of 2,480 patients with undetectable prostate specific antigen 10 years postoperatively 249 subsequently had biochemical recurrence, of whom 12 died of prostate cancer. The factors associated with late biochemical recurrence were age at surgery (HR 1.04 per year, p = 0.027), prostate specific antigen at diagnosis (HR 1.02 per ng/ml, p = 0.020), pathological Gleason score (categorical 2-6 vs 7 [3 + 4], 7, 7 [4 + 3] and 8-10, p = 0.002) and pathological tumor stage pT3a or greater (HR 1.50, p = 0.065). CONCLUSIONS From years 10 to 15 and 10 to 20 postoperatively the biochemical recurrence rate increased by 9.7% and 18.4%, respectively. In contrast to a family history of prostate cancer, age at surgery, prostate specific antigen at diagnosis, pathological tumor stage and pathological Gleason score were prognostic factors for late biochemical recurrence. Patients with late biochemical recurrence are still at risk for death from prostate cancer.

Abstract
Prostate cancer is the most commonly diagnosed noncutaneous cancer and second-leading cause of death in men. Many patients with clinically organ-confined prostate cancer undergo definitive treatment of the whole gland including radical prostatectomy, radiation therapy, and cryosurgery. Active surveillance is a growing alternative option for patients with documented low-volume, low-grade prostate cancer. With recent advances in software and hardware of MRI, multiparametric MRI of the prostate has been shown to improve the accuracy in detecting and characterizing clinically significant prostate cancer. Targeted biopsy is increasingly utilized to improve the yield of MR-detected, clinically significant prostate cancer and to decrease in detection of indolent prostate cancer. MR-guided targeted biopsy techniques include cognitive MR fusion TRUS biopsy, in-bore transrectal targeted biopsy using robotic transrectal device, and in-bore direct MR-guided transperineal biopsy with a software-based transperineal grid template. In addition, advances in MR compatible thermal ablation technology allow accurate focal or regional delivery of optimal thermal energy to the biopsy-proved, MRI-detected tumor, utilizing cryoablation, laser ablation, high-intensity focused ultrasound ablation under MR guidance and real-time or near simultaneous monitoring of the ablation zone. Herein we present a contemporary review of MR-guided targeted biopsy techniques of MR-detected lesions as well as MR-guided focal or regional thermal ablative therapies for localized naïve and recurrent cancerous foci of the prostate.

Abstract
Localized prostate cancer (PCa) is a clinically heterogeneous disease, which presents with variability in patient outcomes within the same risk stratification (low, intermediate or high) and even within the same Gleason scores. Genomic tools have been developed with the purpose of stratifying patients affected by this disease to help physicians personalize therapies and follow-up schemes. This review focuses on these tissue-based tools. At present, four genomic tools are commercially available: Decipher™, Oncotype DX®, Prolaris® and ProMark®. Decipher™ is a tool based on 22 genes and evaluates the risk of adverse outcomes (metastasis) after radical prostatectomy (RP). Oncotype DX® is based on 17 genes and focuses on the ability to predict outcomes (adverse pathology) in very low-low and low-intermediate PCa patients, while Prolaris® is built on a panel of 46 genes and is validated to evaluate outcomes for patients at low risk as well as patients who are affected by high risk PCa and post-RP. Finally, ProMark® is based on a multiplexed proteomics assay and predicts PCa aggressiveness in patients found with similar features to Oncotype DX®. These biomarkers can be helpful for post-biopsy decision-making in low risk patients and post-radical prostatectomy in selected risk groups. Further studies are needed to investigate the clinical benefit of these new technologies, the financial ramifications and how they should be utilized in clinics.

Abstract
Background Surgery plus adjuvant radiotherapy is standard care for locally advanced prostate cancer (stage pT3R1). Intraoperative low-energy photon radiotherapy offers several advantages over external beam radiotherapy, and several systems are now available for its delivery, using spherical applicators, which require only limited shielding. The aim of this study was to evaluate the feasibility of this technique for the prostate bed. Materials and methods Applicators were assessed using MRI image data and cadaveric dissection. In cadavers, targeted tissues, defined as a urethral section, both neurovascular bundle sections, the bladder neck and the beds of the seminal vesicles, were marked with metallic surgical clips. Distances between clips and applicator were measured using CT. A dosimetric study of the application of 12 Gy at 5 mm depth was performed using CT images of prostatectomized cadavers. Results Using MRI images from 34 prostate cancer patients, we showed that the ideal applicator diameter ranges from 45 to 70 mm. Using applicators of different sizes to encompass the prostate bed in nine cadavers, we showed that the distance between target tissues and applicator was <2 mm for all target tissues except the upper extremity of the seminal vesicles (19 mm). Dosimetric study showed a good dose distribution in all target tissues in contact with the applicator, with a low probability of rectum and bladder complication. Conclusion Intraoperative radiotherapy of the prostate bed is feasible, with good coverage of targeted tissues. Clinical study of safety and efficacy is now required.
