Effects of Bony Pelvic and Prostate Dimensions on Surgical Difficulty of Robot-Assisted Radical Prostatectomy: An Original Study and Meta-analysis. Ann Surg Oncol 2024; 31:8405-8420. [PMID: 39080137 DOI: 10.1245/s10434-024-15769-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 06/25/2024] [Indexed: 08/09/2024]
Abstract
BACKGROUND Due to the deep location of the prostate within the pelvic cavity, procedures of robot-assisted radical prostatectomy (RARP) might be challenged by the prostate size and the limited pelvic cavity space. This study aimed to investigate the roles of bony pelvic and prostate dimensions in RARP procedures by an original study coupled with a meta-analysis. METHODS In the original study, patients undergoing multiport RARP between 2021 and 2022 were consecutively assessed. The associations of anatomic features with operative time (OT), estimated blood loss (EBL), and positive surgical margin (PSM) were evaluated using linear and logistic regression analyses as well as restricted cubic spline (RCS) analysis. Based on machine-learning algorithms, this study established predictive models for surgical difficulty and interpreted the model using SHapley Additive exPlanation (SHAP). In the meta-analysis, three databases were searched for eligible studies. Quantitative syntheses were subsequently performed. RESULTS Overall, 219 patients were enrolled in the original study. Prostate volume (PV) and the prostate volume-to-pelvic cavity index (PCI) ratio (PV-to-PCI ratio) were significantly associated with longer OT (P < 0.05). In the RCS models, U-shaped associations were observed between the prostate anteroposterior diameter (PAD) and OT, and between the prostate height (PH) and EBL, and an L-shaped association was observed between the anteroposterior diameter of the pelvic inlet (API) and EBL. The XGBoost model was superior to the logistic regression model in predicting prolonged OT. The meta-analysis demonstrated that greater PV was significantly associated with longer OT (β = 0.20; 95% confidence interval [CI] 0.12-0.27; odds ratio [OR] = 1.05; 95% CI 1.00-1.11), and a smaller PV could increase the risk of PSM (OR = 0.82; 95% CI 0.77-0.88). CONCLUSIONS A large prostate within a narrow and deep pelvis might suggest increased surgical difficulty of RARP. The size of the pelvic inlet also had a great impact on RARP. For PAD and PH, there seemed to be an optimal range with the lowest surgical difficulty. Machine-learning models based on the XGBoost algorithm could be successfully applied to predict the surgical difficulty of RARP.

Prostate 2024; 84:491-501. [PMID: 38173273 DOI: 10.1002/pros.24667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 12/11/2023] [Accepted: 12/15/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND Radical prostatectomy remains the main choice of treatment for prostate cancer. However, despite improvements in surgical techniques and neurovascular sparing procedures, rates of erectile dysfunction, and urinary incontinence remain variable. This is due, at least in part, to an incomplete understanding of neurovascular structures associated with the prostate. The objective of this study was to provide a comprehensive, detailed histological overview of the distribution of nerves and blood vessels within the prostate, facilitating subsequent correlation of prostatic neurovascular structures with patients' clinical outcomes after radical prostatectomy. METHODS Neurovascular structures within the prostate were investigated in a total of 309 slides obtained from 15 patients who underwent non-nerve-sparing radical prostatectomy. Immunohistochemical staining was performed to identify and distinguish between parasympathetic and sympathetic nerves, whereas hematoxylin and eosin staining was used to identify blood vessels. The total number, density, and relative position of nerves and blood vessels were established using quantitative morphometry and illustrated using visualization approaches. Patient-specific outcome data were then used to establish whether the internal distribution of nerves and blood vessels within the prostate correlated with the nature and extent of complications after surgery. One-way analysis of variance tests and unpaired t tests were applied to establish statistically significant differences across the measured variables. RESULTS Nerves and blood vessels were present across all prostatic levels and regions. However, their number and density varied considerably between regions. Assessment of the precise positioning of neurovascular structures revealed that the majority of nerve fibers were located within the dorsal and peripheral aspects of the gland. In contrast, blood vessels were predominantly located within ventral and dorsal midline regions. The number of intraprostatic nerves was found to be significantly lower in patients who recovered their continence within 12 months of surgery, compared to those whose recovery took 12 months or longer. CONCLUSION We report an unexpected disconnect between the localization and positioning of nerve fibers and blood vessels within the prostate. Moreover, individual variability in the density of intraprostatic neurovascular structures appears to correlate with the successful recovery of urinary continence after radical prostatectomy, suggesting that differences in intrinsic neurovascular arrangements of the prostate influence postoperative outcomes.

Abstract
BACKGROUND Prostate cancer (PCa) is one of the most common malignant tumors in men, and laparoscopic radical prostatectomy (LRP) is commonly used to treat localized and advanced PCa. Positive surgical margin (PSM) is one of the most frequent problems faced by surgeons. AIMS This study aimed to explore the value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red blood cell distribution width (RDW) in predicting PSM after LRP. METHODS AND RESULTS Three hundred and twenty patients with PCa were admitted and underwent LRP in Beijing Chaoyang Hospital from January 2017 to June 2023. Patients were randomly divided into a training set (225 cases) and a validation set (95 cases) in a 7:3 ratio. NLR, PLR, and RDW were significantly higher in the PSM group than in the negative surgical margins (NSM) group. In addition, the NLR, PLR, and RDW values correlated with clinical T stage, Gleason score, and seminal vesicle invasion in the PSM group. In training set, ROC curve analysis revealed that the optimal cutoff values of NLR, PLR, and RDW for predicting postoperative PSM in PCa were 2.31, 115.40, and 12.85%, respectively. Multivariate Logistic regression analysis showed NLR and RDW were the clinical independent predictors. The area under the curve (AUC, 0.770, 95% CI 0.709-0.831) for postoperative PSM was the highest when a combination of the three parameters was used, with sensitivity and specificity of 62.5% and 85.2%, respectively. In validation set, the AUC values for NLR, PLR, RDW and the three markers combined were 0.708, 0.675, 0.723, and 0.780, respectively. Correlation analysis showed that in the PSM group, NLR was positively correlated with PLR and RDW, and PLR was positively correlated with RDW. By contrast, in the NSM group, a positive association was only found between NLR and PLR. CONCLUSIONS Higher preoperative NLR, PLR, and RDW values were associated with postoperative PSM. Additionally, the three markers combined may be useful to predict PSM.

Abstract
Introduction A positive surgical margin (PSM) in the radical prostatectomy (RP) specimen is associated with biochemical recurrence (BCR) and the need for adjuvant radiation therapy, and is an analysis of surgical procedure quality. We present data describing the identification, anatomy, and management of PSM after RP performed via an open operation and laparoscopically. The aim of the study was to compare assessment of RP (open vs. laparoscopic) in terms of analysis of PSM in postoperative histopathological tissue. Material and methods Patients with pT1 to pT3b prostate cancer with detailed surgical margin parameters and BCR status were analysed. The patients were divided into groups depending on the stage of neoplastic disease and the choice of operative procedure. Results In total, we obtained data from 140 PC patients. Positive surgical margins were confirmed in 11 cases treated with open surgery and in 7 cases treated with laparoscopic procedure. There was no statistically significant (p >0.05) relationship between the frequency of positive margins and the type of procedure. There was no statistically significant (p >0.05) relationship between the frequency of positive margins and the type of procedure in subgroups according to the Gleason score. There was a statistically significant (p <0.05) relationship between the clinical stage of the tumor and the type of margin. This particularly refers to tumours with stage T3b (more numerous in the group of open surgeries) and T2c (more numerous in the laparoscopic group). Conclusions There was no statistically significant correlation between the type of surgery and the incidence of a positive surgical margin.

Abstract
Objective Positive surgical margins (PSMs) after radical prostatectomy (RP) indicate failure of surgery to completely clear cancer. PSMs confer an increased risk of biochemical recurrence (BCR), but how more robust outcomes are affected is unclear. This study investigated factors associated with PSMs following RP and determined their impact on clinical outcomes (BCR, second treatment [radiotherapy and/or androgen deprivation therapy], and prostate cancer-specific mortality [PCSM]). Methods The study cohort included men diagnosed with prostate cancer (pT2-3b/N0/M0) between January 1998 and June 2016 who underwent RP from the South Australian Prostate Cancer Clinical Outcomes Collaborative database. Factors associated with risk of PSMs were identified using Poisson regression. The impact of PSMs on clinical outcomes (BCR, second treatment, and PCSM) was assessed using competing risk regression. Results Of the 2827 eligible participants, 28% had PSMs-10% apical, 6% bladder neck, 17% posterolateral, and 5% at multiple locations. Median follow-up was 9.6 years with 81 deaths from prostate cancer recorded. Likelihood of PSM increased with higher pathological grade and pathological tumor stage, and greater tumour volume, but decreased with increasing surgeon volume (odds ratio [OR]: 0.93; 95% confidence interval [CI]: 0.88-0.98, per 100 previous prostatectomies). PSMs were associated with increased risk of BCR (adjusted sub-distribution hazard ratio [sHR] 2.5; 95% CI 2.1-3.1) and second treatment (sHR 2.9; 95% CI 2.4-3.5). Risk of BCR was increased similarly for each PSM location, but was higher for multiple margin sites. We found no association between PSMs and PCSM. Conclusion Our findings support previous research suggesting that PSMs are not independently associated with PCSM despite strong association with BCR. Reducing PSM rates remains an important objective, given the higher likelihood of secondary treatment with associated comorbidities.

Abstract
BACKGROUND The effect of positive surgical margins (PSM) on cancer specific mortality (CSM) in high/very high-risk (HR/VHR) prostate cancer (PCa) with aggressive Gleason Grade Group (GGG) is unknown. We tested PSM effect on CSM in this setting, in addition to testing of radiotherapy (RT) benefit in PSM patients. METHODS We relied on Surveillance, Epidemiology, and End Results database (2010-2015), focusing on HR/VHR patients with exclusive GGG 4-5 at radical prostatectomy (RP). Kaplan-Meier plots and multivariable Cox regression models tested the relationship between PSM and CSM. Moreover, the effect of RT on CSM was explored in PSM patients. RESULTS Of 3383 HR/VHR patients, 15.1% (n = 511) exhibited PSM. Patients with PSM harbored higher rates of GGG 5 (60.1% vs. 50.9%, p < 0.001), pathologic tumor stage T3a (69.1% vs. 45.2%, p < 0.001) and lymph node involvement (14.1% vs. 9.4%, p < 0.001), relative to patients without PSM. PSM rates decreased over time (2010-2015) from 16.0% to 13.6%. Seven-year CSM-free survival rates were 91.6% versus 95.7% in patients with and without PSM, respectively. In multivariable Cox regression models, PSM was an independent predictor of CSM (hazard ratio = 1.6, p = 0.040) even after adjustment for age, prostate specific antigen, pathologic tumor stage and lymph node status. Finally, in PSM patients, RT delivery did not reduce CSM in either univariable or multivariable Cox regression models. CONCLUSIONS In HR/VHR PCa patients with exclusive GGG 4-5, PSM at RP adversely affect survival. Moreover, RT has no protective effect on CSM. In consequence, lowest possible PSM rates are crucial in such patients.

Abstract
CONTEXT Positive surgical margin (PSM) on radical prostatectomy (RP) is associated with an increased risk of biochemical recurrence and use of salvage therapies. Given these adverse consequences, exploration of time trends and predictors of PSM will improve the patient outcomes following surgery for prostate cancer. METHODS Pathological data from RP patients treated from 2011 to 2020 was extracted from the Victorian Prostate Cancer Outcomes Registry. This is a clinical quality registry that regularly benchmarks and reports back to individual clinicians the PSM percentage for their patients. Trends in PSM over time were visualized with separate running mean plots for both pT2 and pT3/4 disease. Predictors of PSM were explored with multivariable regression with date of surgery, surgical method, and hospital type, public or private, entered as covariates. RESULTS In total, 12,394 patients formed the sample with PSM recorded in 25% (n = 3,141) of patients, 12% (777/6,640) in pT2 disease and 41% (2,364/5,754) in pT3/4 disease. Comparing 2011-12 to 2019-20, the pT3/4 PSM proportion declined from 50% to 38% while pT2 percentages were steady at 13%. In "high volume" institutions, pT2 PSM fell from 12% to 6.5%. Independent predictors of lower PSM were robotic vs. open method and being treated at a private vs. public institution. CONCLUSION A clear decline in the proportion of pT3 PSM was observed in a large prostate cancer registry. Proposed explanatory factors include improved technical proficiency with robotic surgery and participation in a registry-based quality improvement initiative.

Abstract
BACKGROUND Follow-up during Active Surveillance (AS) may result in psychological burden and discomfort due to the constant clinical monitoring. Therefore, successful implementation of AS is to some extent a challenge for the patient and the caregiver. MATERIALS AND METHODS In this monocentric study, we analyzed the reasons for termination of AS and the rate of the postoperative adverse pathology (AP) in patients who underwent deferred radical prostatectomy (RP) after AS. These results were compared with AS candidates who underwent immediate RP. P-values were calculated with the Χ2 test. RESULTS After 21 months of follow-up during AS, a deferred RP was performed in 74 patients. On the other hand, 214 patients underwent immediate RP. AP (Gleason score ≥7b, ≥pT3a, R1 and N+) was common in the AS group and this was statistically significant (45% vs. 29%, P-value <0.001). CONCLUSION These findings reflect many deficits in the current AS protocols. Using the available tools to apply AS in the routine clinical practice setting may be not adequate to afford oncological safety. This requires the development of new diagnostic tools like new imaging techniques and innovative biomarkers that provide the clinician with more accurate data about disease progression and subsequent help to achieve better outcomes in active surveillance candidates.

Abstract
BACKGROUND Delayed recovery of urinary continence is a major adverse effect of robotic-assisted laparoscopic prostatectomy (RALP) in men undergoing prostate cancer treatment. To address this issue, a number of surgical techniques have been designed to reconstruct the posterior aspect of the rhabdosphincter, which is responsible for urinary continence after removal of the prostate; however, it is unclear how well they work. OBJECTIVES: To assess the effects of posterior musculofascial reconstruction RALP compared to no posterior reconstruction during RALP for the treatment of clinically localized prostate cancer. SEARCH METHODS We performed a comprehensive search of the Cochrane Library, MEDLINE, Embase, three other databases, trials registries, other sources of the grey literature, and conference proceedings, up to 12 March 2021. We applied no restrictions on publication language or status. SELECTION CRITERIA We included randomized controlled trials (RCTs) in which participants were randomized to undergo variations of posterior musculofascial reconstruction RALP versus no posterior reconstruction during RALP for clinically localized prostate cancer. DATA COLLECTION AND ANALYSIS Two review authors independently classified studies and abstracted data from the included studies. Primary outcomes were: urinary continence recovery within one week after catheter removal, at three months after surgery, and serious adverse events. Secondary outcomes were: urinary continence recovery at six and twelve months after surgery, potency recovery twelve months after surgery, positive surgical margins (PSM), and biochemical recurrence-free survival (BCRFS). We performed statistical analyses using a random-effects model. We rated the certainty of evidence (CoE) according to the GRADE approach. MAIN RESULTS Our search identified 13 records of eight unique RCTs, of which six were published studies and two were abstract proceedings. We included 1085 randomized participants, of whom 963 completed the trials (88.8%). All participants had either cT1c or cT2 or cT3a disease, with a mean prostate-specific antigen level of 8.15 ng/mL. Primary outcomes Posterior reconstruction RALP (PR-RALP) may improve urinary continence one week after catheter removal compared to no posterior reconstruction during RALP (risk ratio (RR) 1.25, 95% confidence interval (CI) 0.90 to 1.73; I2 = 42%; studies = 5, participants = 498; low CoE) although the CI also includes the possibility of no effect. Assuming 335 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 84 more men per 1000 (33 fewer to 244 more) reporting urinary continence recovery. Posterior reconstruction may have little to no effect on urinary continence three months after surgery compared to no posterior reconstruction during RALP (RR 0.98, 95% CI 0.84 to 1.14; I2 = 67%; studies = 6, participants = 842; low CoE). Assuming 701 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 14 fewer men per 1000 (112 fewer to 98 more) reporting urinary continence after three months. PR-RALP probably results in little to no difference in serious adverse events compared to no posterior reconstruction during RALP (RR 0.75, 95% CI 0.29 to 1.92; I2 = 0%; studies = 6, participants = 835; moderate CoE). Assuming 25 per 1000 men undergoing standard RALP experience a serious adverse event at this time point, this corresponds to six fewer men per 1000 (17 fewer to 23 more) reporting serious adverse events. Secondary outcomes PR-RALP may result in little to no difference in recovery of continence 12 months after surgery compared to no posterior reconstruction during RALP (RR 1.02, 95% CI 0.98 to 1.07; I2 = 25%; studies = 3, participants = 602; low CoE). Assuming 918 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 18 more men per 1000 (18 fewer to 64 more) reporting urinary continence recovery. We are very uncertain about the effects of PR-RALP on recovery of potency 12 months after surgery compared to no posterior reconstruction during RALP (RR 1.02, 95% CI 0.82 to 1.26; I2 = 3%; studies = 2, participants = 308; very low CoE). Assuming 433 per 1000 men undergoing standard RALP are potent at this time point, this corresponds to nine more men per 1000 (78 fewer to 113 more) reporting potency recovery. PR-RALP may result in little to no difference in positive surgical margins compared to no posterior reconstruction during RALP (RR 1.24, 95% CI 0.65 to 2.33; I2 = 50%; studies = 3, participants = 517; low CoE). Assuming 130 per 1000 men undergoing standard RALP have a positive surgical margin, this corresponds to 31 more men per 1000 (46 fewer to 173 more) reporting positive surgical margins. PR-RALP may result in little to no difference in biochemical recurrence compared to no posterior reconstruction during RALP (RR 1.36, 95% CI 0.74 to 2.52; I2 = 0%; studies = 2, participants = 468; low CoE). Assuming 70 per 1000 men undergoing standard RALP have experienced biochemical recurrence at this time point, this corresponds to 25 more men per 1000 (18 fewer to 107 more) reporting biochemical recurrence. AUTHORS' CONCLUSIONS: This review found evidence that PR-RALP may improve early continence one week after catheter removal but not thereafter. Meanwhile, adverse event rates are probably not impacted and surgical margins rates are likely similar. This review was unable to determine if or how these findings may be impacted by the person's age, nerve-sparing status, or clinical stage. Study limitations, imprecision, and inconsistency lowered the certainty of evidence for the outcomes assessed.

Abstract
Background and Objectives Previous studies have demonstrated that positive surgical margins (PSMs) were independent predictive factors for biochemical and oncologic outcomes in patients with prostate cancer (PCa). This study aimed to conduct a meta-analysis to identify the predictive factors for PSMs after radical prostatectomy (RP). Methods We selected eligible studies via the electronic databases, such as PubMed, Web of Science, and EMBASE, from inception to December 2020. The risk factors for PSMs following RP were identified. The pooled estimates of standardized mean differences (SMDs)/odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. A fixed effect or random effect was used to pool the estimates. Subgroup analyses were performed to explore the reasons for heterogeneity. Results Twenty-seven studies including 50,014 patients with PCa were eligible for further analysis. The results showed that PSMs were significantly associated with preoperative prostate-specific antigen (PSA) (pooled SMD = 0.37; 95% CI: 0.31–0.43; P < 0.001), biopsy Gleason Score (<6/≥7) (pooled OR = 1.53; 95% CI:1.31–1.79; P < 0.001), pathological Gleason Score (<6/≥7) (pooled OR = 2.49; 95% CI: 2.19–2.83; P < 0.001), pathological stage (<T2/≥T3) (pooled OR = 3.90; 95% CI: 3.18–4.79; P < 0.001), positive lymph node (PLN) (pooled OR = 3.12; 95% CI: 2.28–4.27; P < 0.001), extraprostatic extension (EPE) (pooled OR = 4.44; 95% CI: 3.25–6.09; P < 0.001), and seminal vesicle invasion (SVI) (pooled OR = 4.19; 95% CI: 2,87–6.13; P < 0.001). However, we found that age (pooled SMD = 0.01; 95% CI: −0.07–0.10; P = 0.735), body mass index (BMI) (pooled SMD = 0.12; 95% CI: −0.05–0.30; P = 0.162), prostate volume (pooled SMD = −0.28; 95% CI: −0.62–0.05; P = 0.097), and nerve sparing (pooled OR = 0.90; 95% CI: 0.71–1.14; P = 0.388) had no effect on PSMs after RP. Besides, the findings in this study were found to be reliable by our sensitivity and subgroup analyses. Conclusions Preoperative PSA, biopsy Gleason Score, pathological Gleason Score, pathological stage, positive lymph node, extraprostatic extension, and seminal vesicle invasion are independent predictors of PSMs after RP. These results may helpful for risk stratification and individualized therapy in PCa patients.

Abstract
INTRODUCTION Risk assessment for non-organ-confined prostate cancer (PCa) is important in the surgical planning for radical prostatectomy (RP). Perineural invasion (PNI) on prostate biopsy has been associated with adverse pathological outcomes at prostatectomy. Similarly, the identification of suspected extracapsular extension (ECE) on multiparametric magnetic resonance imaging (mpMRI) has been shown to predict non-organ-confined disease. However, no prior study has compared these factors in predicting adverse pathology at prostatectomy. We evaluated mpMRI ECE and prostate biopsy PNI on multivariable analysis to determine their ability to predict pathological stage at time of RP. METHODS We retrospectively investigated the prostatectomy database at our institution to identify men who underwent prostate biopsy with pre-biopsy mpMRI and subsequent RP from 2013-2017. Multivariable regression analysis was performed to compare the association of mpMRI ECE (mECE) and PNI on prostate biopsy on the likelihood of finding pT3 disease on pathology post-prostatectomy. RESULTS Of a total 454 RP between 2013 and 2017, 191 patients met our inclusion criteria. Stage pT2 and pT3+ were found in 120 (62.8%) and 71 (37.2%) patients, respectively. Patients with mECE had 4.84 cumulative odds of worse pathological stage on RP (p=0.045) compared to PNI on biopsy, which showed cumulative odds of 2.25 (p=0.048). When controlling only for those patients without PNI, mECE was still found to be a significant predictor of pT3 disease at RP (p=0.030); however, in patients without mECE, PNI was not significant (p=0.062). CONCLUSIONS While mECE and biopsy PNI were both associated with worse pathological stage on RP, mECE had significantly higher cumulative odds compared to PNI. The significant predictive ability of mECE adds further clinical value to the use of mpMRI in PCa management. While validation in a larger cohort is required, these factors have important clinical implications with regards to early diagnosis of advanced disease and surgical planning.

Abstract
Objective To determine whether evaluating the mean apparent diffusion coefficient (ADC) together with capsular contact (CC) adds value in the prediction of microscopic extracapsular extension (ECE) of prostate cancer. Materials and Methods Between January 2012 and December 2016, 383 patients underwent multiparametric magnetic resonance imaging (mpMRI) of the prostate. A total of 67 patients were selected for inclusion. Two radiologists (observers 1 and 2), working independently, performed qualitative and quantitative analyses of ECE, macroscopic ECE, and microscopic ECE. A third radiologist assessed the correlation with the clinical data, and two experienced pathologists reviewed all histopathological findings. Results Among the 67 patients, mpMRI showed lesions that were confined to the capsule in 44 (66.7%), had microscopic ECE in 12 (17.9%), and had macroscopic ECE in 11 (16.4%). There were no significant differences, in terms of the diagnostic accuracy, as measured by determining the area under the curve (AUC), of CC on T2-weighted images (CCT2), CC on diffusion-weighted imaging (CCDWI), and the mean ADC for the prediction of microscopic ECE, between observer 1 (AUC of 0.728, 0.691, and 0.675, respectively) and observer 2 (AUC of 0.782, 0.821, and 0.799, respectively). Combining the mean ADC with the CCT2 or CCDWI did not improve the diagnostic accuracy for either observer. There was substantial interobserver agreement for the qualitative evaluation of ECE, as demonstrated by the kappa statistic, which was 0.77 (0.66-0.87). The diagnostic accuracy (AUC) of the qualitative assessment for predicting microscopic ECE was 0.745 for observer 1 and 0.804 for observer 2, and the difference was less than significant. In a multivariate analysis, none of clinical or imaging parameters were found to be associated with ECE. Conclusion For the detection of microscopic ECE on mpMRI, CC appears to have good diagnostic accuracy, especially if the observer has considerable experience. Adding the mean ADC to the CCT2 or CCDWI does not seem to provide any significant improvement in that diagnostic accuracy.

Abstract
BACKGROUND Robotic-assisted laparoscopic prostatectomy (RALP) is widely used to surgically treat clinically localized prostate cancer. It is typically performed using an approach (standard RALP) that mimics open retropubic prostatectomy by dissecting the so-called space of Retzius anterior to the bladder. An alternative, Retzius-sparing (or posterior approach) RALP (RS-RALP) has been described, which is reported to have better continence outcomes but may be associated with a higher risk of incomplete resection and positive surgical margins (PSM). OBJECTIVES To assess the effects of RS-RALP compared to standard RALP for the treatment of clinically localized prostate cancer. SEARCH METHODS We performed a comprehensive search of the Cochrane Library, MEDLINE, Embase, three other databases, trials registries, other sources of the grey literature, and conference proceedings, up to June 2020. We applied no restrictions on publication language or status. SELECTION CRITERIA We included trials where participants were randomized to RS-RALP or standard RALP for clinically localized prostate cancer. DATA COLLECTION AND ANALYSIS Two review authors independently classified and abstracted data from the included studies. Primary outcomes were: urinary continence recovery within one week after catheter removal, at three months after surgery, and serious adverse events. Secondary outcomes were: urinary continence recovery six and 12 months after surgery, potency recovery 12 months after surgery, positive surgical margins (PSM), biochemical recurrence-free survival (BCRFS), and urinary and sexual function quality of life. We performed statistical analyses using a random-effects model. We rated the certainty of evidence using the GRADE approach. MAIN RESULTS Our search identified six records of five unique randomized controlled trials, of which two were published studies, one was in press, and two were abstract proceedings. There were 571 randomized participants, of whom 502 completed the trials. Mean age of participants was 64.6 years and mean prostate-specific antigen was 6.9 ng/mL. About 54.2% of participants had cT1c disease, 38.6% had cT2a-b disease, and 7.1 % had cT2c disease. Primary outcomes RS-RALP probably improves continence within one week after catheter removal (risk ratio (RR) 1.74, 95% confidence interval (CI) 1.41 to 2.14; I2 = 0%; studies = 4; participants = 410; moderate-certainty evidence). Assuming 335 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 248 more men per 1000 (137 more to 382 more) reporting continence recovery. RS-RALP may increase continence at three months after surgery compared to standard RALP (RR 1.33, 95% CI 1.06 to 1.68; I2 = 86%; studies = 5; participants = 526; low-certainty evidence). Assuming 750 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 224 more men per 1000 (41 more to 462 more) reporting continence recovery. We are very uncertain about the effects of RS-RALP on serious adverse events compared to standard RALP (RR 1.40, 95% CI 0.47 to 4.17; studies = 2; participants = 230; very low-certainty evidence). Secondary outcomes There is probably little to no difference in continence recovery at 12 months after surgery (RR 1.01, 95% CI 0.97 to 1.04; I2 = 0%; studies = 2; participants = 222; moderate-certainty evidence). Assuming 982 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 10 more men per 1000 (29 fewer to 39 more) reporting continence recovery. We are very uncertain about the effect of RS-RALP on potency recovery 12 months after surgery (RR 0.98, 95% CI 0.54 to 1.80; studies = 1; participants = 55; very low-certainty evidence). RS-RALP may increase PSMs (RR 1.95, 95% CI 1.19 to 3.20; I2 = 0%; studies = 3; participants = 308; low-certainty evidence) indicating a higher risk for prostate cancer recurrence. Assuming 129 per 1000 men undergoing standard RALP have positive margins, this corresponds to 123 more men per 1000 (25 more to 284 more) with PSMs. We are very uncertain about the effect of RS-RALP on BCRFS compared to standard RALP (hazard ratio (HR) 0.45, 95% CI 0.13 to 1.60; I2 = 32%; studies = 2; participants = 218; very low-certainty evidence). AUTHORS' CONCLUSIONS Findings of this review indicate that RS-RALP may result in better continence outcomes than standard RALP up to six months after surgery. Continence outcomes at 12 months may be similar. Downsides of RS-RALP may be higher positive margin rates. We are very uncertain about the effect on BCRFS and potency outcomes. Longer-term oncologic and functional outcomes are lacking, and no preplanned subgroup analyses could be performed to explore the observed heterogeneity. Surgeons should discuss these trade-offs and the limitations of the evidence with their patients when considering this approach.

Abstract
OBJECTIVE To report the first application of ex vivo fluorescence confocal microscopy (FCM) - a novel optical technology that is capable of providing fast microscopic imaging of unfixed tissue specimens- in the urological field assessing its diagnostic accuracy for non neoplastic and cancerous prostate tissue (prostatic adenocarcinoma) compared to the 'gold standard' histopathological diagnoses. PATIENTS AND METHODS In all, 89 specimens from 13 patients with clinically localised prostate cancer were enrolled into the study. All patients underwent robot-assisted laparoscopic radical prostatectomy with fresh prostatic tissue biopsies taken at the end of each intervention using an 18-G biopsy punch. Specimens were randomly assigned to the three collaborating pathologists for evaluation. Intra- and inter-observer agreement was tested by the means of Cohen's κ. The diagnostic performance was evaluated on receiver operating characteristic curve analysis. RESULTS The overall diagnostic agreement between FCM and histopathological diagnoses was substantial with a 91% correct diagnosis (κ = 0.75) and an area under the curve of 0.884 (95% confidence interval 0.840-0.920), 83.33% sensitivity, and 93.53% specificity. CONCLUSION FCM seems to be a promising tool for enhanced specimens' reporting performance, given its simple application and very rapid microscopic image generation (<5 min/specimen). This technique may potentially be used for intraoperative pathological specimens' analysis.

Abstract
Radical prostatectomy is frequently performed as a curative approach for clinically localized prostate cancer. In order to reduce the adverse effects of this operation on erectile function, preservation of neurovascular bundles was introduced as part of this operation. The decision of nerve sparing must be carefully tailored in each patient according to the stage of the disease. Patient selection has a critical importance in performing nerve sparing radical prostatectomy. In organ-confined cancers a nerve sparing surgery can be performed in the majority of the cases without jeopardizing tumor control. Individualized decision making in each case may allow more patients to receive a nerve sparing approach, and therefore, better functional outcomes. However, it continues to be difficult to predict postoperative functional outcomes accurately due to many influencing factors.

Positive Surgical Margins in the 10 Most Common Solid Cancers. Sci Rep 2018; 8:5686.

Abstract
A positive surgical margin (PSM) following cancer resection oftentimes necessitates adjuvant treatments and carries significant financial and prognostic implications. We sought to compare PSM rates for the ten most common solid cancers in the United States, and to assess trends over time. Over 10 million patients were identified in the National Cancer Data Base from 1998–2012, and 6.5 million had surgical margin data. PSM rates were compared between two time periods, 1998–2002 and 2008–2012. PSM was positively correlated with tumor category and grade. Ovarian and prostate cancers had the highest PSM prevalence in women and men, respectively. The highest PSM rates for cancers affecting both genders were seen for oral cavity tumors. PSM rates for breast cancer and lung and bronchus cancer in both men and women declined over the study period. PSM increases were seen for bladder, colon and rectum, and kidney and renal pelvis cancers. This large-scale analysis appraises the magnitude of PSM in the United States in order to focus future efforts on improving oncologic surgical care with the goal of optimizing value and improving patient outcomes.

Abstract
BACKGROUND A positive surgical margin (PSM) following radical prostatectomy (RP) for prostate cancer is associated with increased risk of biochemical recurrence. We sought to examine whether the pathologist is an independent predictor of PSMs. METHODS We performed a retrospective review of 3,557 men who underwent RP for localized prostate cancer at our institution from 2003 to 2015. We evaluated 29 separate pathologists. Univariate and multivariable logistic regression were used to test variables previously shown to influence PSM rates. RESULTS Overall rate of PSM was 18.9%. Compared with patients without PSM, patients with PSM had higher body mass index (mean: 28.8 vs. 28.3), Gleason score≥7 (84% vs. 66%), extracapsular extension (51% vs. 20%), and median prostate-specific antigen (5.9 vs. 5.1ng/ml) (all P<0.05). Univariate logistic regression showed that surgeon experience, pathologist experience, and pathologist genitourinary fellowship training were all predictors of PSMs (all P<0.05). Multivariable regression analysis confirmed that decreased surgeon experience, increased pathologist experience, higher pathologic Gleason score, higher pathologic stage, and higher prostate-specific antigen were significant predictors of PSMs. Increasing surgeon experience was associated with decreased odds of PSM (odds ratio = 0.79 per 1 standard deviation increase, 95% CI [0.70-0.89]). In contrast, increasing pathologist experience was associated with increased odds of PSM (odds ratio = 1.11 per 1 standard deviation increase, 95% CI [1.03-1.19]). The relationship between pathologist experience and PSM appeared to be nonlinear (Fig. 2). CONCLUSIONS Greater pathologist experience appears to be associated with greater odds of PSMs following radical prostatectomy, even after controlling for case mix, pathologist fellowship training, and surgeon experience. Based on these findings, pathologists with less experience reviewing RP specimens may consider requesting rereview by a dedicated genitourinary pathologist.

Are you now a good surgeon? T2 positive margin status as a quality outcome measure following radical prostatectomy. World J Urol 2016; 35:35-43. [PMID: 27112152 PMCID: PMC5233732 DOI: 10.1007/s00345-016-1836-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2015] [Accepted: 04/18/2016] [Indexed: 11/22/2022] Open
Abstract
Objective To assess potential biases, such as the reporting pathologist, that may affect objectivity of T2 positive margin rates as a quality outcome measure following radical prostatectomy. Patients and methods Prospective data on 183 consecutive LRP patients with pT2 disease, operated on by a single surgeon (2003–2009), were studied. Outcomes were grouped as pre-, peri-, and post-operative and included: age, ethnicity, Gleason score, reporting pathologist, percentage of positive cores, operative time, blood loss, nerve-sparing status, hospital stay and prostate weight. Descriptive analysis and logistic regression analysis were carried out to compare these variables by positive margin status. Results A total of 30 (16.4 %) positive surgical margins (PSMs) were reported. Surgical stage, earlier date of surgery, and lower prostatic weight showed statistically significant associations with PSM status in both univariate and multivariate analysis. The reporting pathologist was not found to be predictive of PSMs (P = 0.855). Conclusion We showed that the reporting pathologist does not influence T2 positive margin status, in contrast to tumour characteristics and surgeon experience. T2 positive margin assessment therefore appears to be an objective quality outcome measure.
