Development of a microultrasound-based nomogram to predict extra-prostatic extension in patients with prostate cancer undergoing robot-assisted radical prostatectomy. Urol Oncol 2024; 42:159.e9-159.e16. [PMID: 38423852 DOI: 10.1016/j.urolonc.2024.01.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/12/2024] [Accepted: 01/26/2024] [Indexed: 03/02/2024]
Abstract
OBJECTIVES To develop a microultrasound-based nomogram including clinicopathological parameters and microultrasound findings to predict the presence of extra-prostatic extension and guide the grade of nerve-sparing. MATERIAL AND METHODS All patients underwent microultrasound the day before robot-assisted radical prostatectomy. Variables significantly associated with extra-prostatic extension at univariable analysis were used to build the multivariable logistic model, and the regression coefficients were used to develop the nomogram. The model was subjected to 1000 bootstrap resamples for internal validation. The performance of the microultrasound-based model was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA). RESULTS Overall, 122/295 (41.4%) patients had a diagnosis of extra-prostatic extension on definitive pathology. Microultrasound correctly identify extra-prostatic extension in 84/122 (68.9%) cases showing a sensitivity and a specificity of 68.9% and 84.4%, with an AUC of 76.6%. After 1000 bootstrap resamples, the predictive accuracy of the microultrasound-based model was 85.9%. The calibration plot showed a satisfactory concordance between predicted probabilities and observed frequencies of extra-prostatic extension. The DCA showed a higher clinical net-benefit compared to the model including only clinical parameters. Considering a 4% cut-off, nerve-sparing was recommended in 173 (58.6%) patients and extra-prostatic extension was detected in 32 (18.5%) of them. CONCLUSION We developed a microultrasound-based nomogram for the prediction of extra-prostatic extension that could aid in the decision whether to preserve or not neurovascular bundles. External validation and a direct comparison with mpMRI-based nomogram is crucial to corroborate our results.

The value of preoperative neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and red blood cell distribution width in predicting positive surgical margin after laparoscopic radical prostatectomy. Cancer Rep (Hoboken) 2024; 7:e1977. [PMID: 38258491 PMCID: PMC10849998 DOI: 10.1002/cnr2.1977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/07/2023] [Accepted: 12/28/2023] [Indexed: 01/24/2024] Open
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
Background Treatment outcomes in intermediate-risk prostate cancer (PCa) may be impaired by adverse pathology misclassification including tumor upgrading and upstaging. Clinical predictors of disease progression need to be improved in this category of patients. Objectives To identify PCa prognostic factors to define prognostic groups in intermediate-risk patients treated with robot-assisted radical prostatectomy (RARP). Design Data from 1143 patients undergoing RARP from January 2013 to October 2020 were collected: 901 subjects had available follow-up, of whom 479 were at intermediate risk. Methods PCa progression was defined as biochemical recurrence and/or local recurrence and/or distant metastases. Study endpoints were evaluated by statistical methods including Cox's proportional hazards, Kaplan-Meyer survival curves, and binomial and multinomial logistic regression models. Results After a median (interquartile range) of 35 months (15-57 months), 84 patients (17.5%) had disease progression, which was independently predicted by the percentage of biopsy-positive cores ⩾ 50% and the International Society of Urological Pathology (ISUP) grade group 3 for clinical factors and by ISUP > 2, positive surgical margins and pelvic lymph node invasion for pathological features. Patients were classified into clinical and pathological groups as favorable, unfavorable (one prognostic factor), and adverse (more than one prognostic factor). The risk of PCa progression increased with worsening prognosis through groups. A significant positive association was found between the two groups; consequently, as clinical prognosis worsened, the risk of detecting unfavorable and adverse pathological prognostic clusters increased in both unadjusted and adjusted models. Conclusion The study identified factors predicting disease progression that allowed the computation of highly correlated prognostic groups. As the prognosis worsened, the risk of PCa progression increased. Intermediate-risk PCa needs more prognostic stratification for appropriate management.

Association between ABO blood group and unfavorable prostate cancer features after radical prostatectomy: Retrospective study of 1149 patients. Curr Urol 2022; 16:256-261. [PMID: 36714226 PMCID: PMC9875211 DOI: 10.1097/cu9.0000000000000146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 08/31/2021] [Indexed: 02/01/2023] Open
Abstract
Objectives To test hypothesized associations between the ABO blood group (ABO-bg) system and the pathological features of prostate cancer (PCa). Material and methods Between January 2013 and September 2019, 1173 patients underwent radical prostatectomy. Associations between ABO-bg levels and pathological features were evaluated using statistical methods. Results Overall, 1149 consecutive patients were evaluated using the ABO-bg system, which was represented by O-bg (42.8%) and A-bg (41.3%), followed by B-bg (11.1%) and AB-bg (4.8%). Only positive surgical margins (PSMs) was correlated with ABO-bg (Pearson correlation coefficient, r = 0.071; p = 0.017), and the risk was increased in group-O (odds ratio [OR], 1.497; 95% confidence interval, 1.149-1.950; p = 0.003) versus non-O-bg. In clinical and pathological models, O-bg was at increased risk of PSM after the adjustment for prostate-specific antigen, percentage of biopsy-positive cores, and high surgical volume (adjusted OR, 1.546; 95% confidence interval, 1.180-2.026; p = 0.002); however, the adjusted OR did not change after the adjustment for tumor load and stage as well as high surgical volume. Conclusions In clinical PCa, the risk of PSM was higher in O-bg versus non-O-bg patients after the adjustment for standard predictors. Confirmatory studies are needed to confirm the association between ABO-bg and unfavorable PCa features.

Abstract
The interpretation of conventional MRI may be limited by the two-dimensional presentation of the images. To develop patient-specific MRI prostate-based virtual and three-dimensional (3D)-printed models. To assess the association between 3D imaging and the pathological outcome of RARP specimen. To assess the clinical applicability of 3D models to guide nerve-sparing robot-assisted radical prostatectomy (RARP). We created virtual 3D and 3D-printed 3D models of 20 prostate cancer patients retrospectively. A comparison was made between conventional MRI and 3D-reconstructed images. The concordance between tumour lesion location in 3D models and pathology reporting of RARP specimens was assessed. Seven urologists assessed the side-specific extent of nerve-sparing based on (1) conventional MR images, (2) virtual 3D models, and (3) 3D-printed models. Clinically relevant changes in nerve-sparing and the absolute agreement between observers was analyzed using the Chi-square test and intra-class correlation coefficient (ICC). The index lesion was correctly visualized in 19/20 (95%) 3D models and the expected location of extraprostatic extension was correctly visualized in all 3D models. Clinically relevant changes in the planned extent of nerve-sparing between MRI and virtual 3D models and MRI and 3D-printed models were found in 25% and 26%. The ICC of the planned extent of nerve-sparing between urologists was 0.40 (95% CI 0.28-0.55) for conventional MRI, 0.52 (95% CI 0.39-0.66) for virtual 3D models and 0.58 (95% CI 0.45-0.71) for 3D-printed models. 3D models of the MRI prostate to guide RARP could aid urologists in the planning of nerve-sparing surgery as shown by a higher inter-observer agreement.

Radical or Not-So-Radical Prostatectomy: Do Surgical Margins Matter? Cancers (Basel) 2021; 14:cancers14010013. [PMID: 35008178 PMCID: PMC8749855 DOI: 10.3390/cancers14010013] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 12/17/2021] [Accepted: 12/20/2021] [Indexed: 02/02/2023] Open
Abstract
Simple Summary Prostate cancer is the second most common noncutaneous malignancy in men. Prostatectomy is a commonly used treatment modality for selected patients. The prostate’s ill-defined borders and its vicinity with vital structures complicate the wide excision of the organ, resulting in positive margins of resection. Neoplastic infiltration of margins of resection in prostatectomy specimens affects patients’ prognosis. The surgical technique and surgeons’ expertise affect the incidence of margin positivity. The location and the extent of positive margins diversify the risk of recurrence, with basal infiltration and multifocal foci of positive margins behaving more aggressively. Pathologists are encouraged to thoroughly report the status of margins of resection, as they provide important information for patients’ prognosis and enable the clinician to decide upon the most appropriate subsequent therapeutic steps. Abstract Prostate cancer is the second most common malignancy in men, and prostatectomy is the treatment of choice for most patients with at least low risk of progression. The presence of positive margins in the radical prostatectomy specimen is considered an adverse pathologic feature, and may prompt additional therapeutic intervention in the patients. The absence of a distinct capsule around the prostate and intraoperative manipulations that aim to minimize postoperative adverse effects, complicate its wide removal. Proper handling of the specimen during the gross processing is essential for accurate determination of the status of margins or resection. Positive margins, defined as the presence of neoplastic glands in the highlighted-with-ink margin of resection, range from 6–38%. The surgical technique, surgeon’s expertise and tumor (i.e., grade and stage) and patients’ (i.e., BMI) characteristics affect the rate of margin positivity. Extensive or multifocal and nonanterior/nonapical positive margins are linked with higher recurrence rates, especially in organ-confined disease, underscoring the need for treating these patients more aggressively. In summary, detailed description of the status of the margins should be performed in every pathology report to determine patients’ prognosis and the most appropriate therapeutic plan.

Abstract
The present study aimed to assess the safety and efficacy of robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa) under anticoagulant (AC) and/or antiplatelet (AP) therapy, as compared to a control group, and to establish possible differences in postoperative-related morbidity. Data of all consecutive patients submitted to elective RARP for PCa from June 2017 to May 2020 at our institution were prospectively collected. Patients were divided according to the use of AC/AP therapy at surgery. The primary endpoint was to determine differences in 90-day postoperative complication rate, while secondary endpoints included differences in transfusion rate, readmission rate and postoperative oncological outcomes between the two groups. Sub-groups analysis was separately performed for patients undergoing pelvic lymphadenectomy and nerve-sparing procedures. Overall, 822 patients were included in the study and divided in 704 control-group patients (group A) and 118 patients under AC/AP therapy at surgery (group B). Despite the higher estimated blood loss between AC/AP takers and the control group, we did not find a significant difference in terms of 90-day postoperative complication rate, transfusion rate, readmission rate and postoperative oncological outcomes (all p > 0.05). In the cohort of patients undergoing nerve-sparing prostatectomy, a higher rate of complications and transfusions were found. At multivariate analysis, ASA score and ongoing medications were independently associated with complication in this sub-group. RARP can be safely and effectively performed in patients with PCa and ongoing AC/AP agents. Attention has to be paid in candidates for nerve-sparing procedures.

Between January 2013 and October 2020, 1114 patients were treated with RARP. Associations of ABO-bg with specimen pathological features were evaluated by statistical methods. Overall, 305 patients were low risk (27.4%), 590 intermediate risk (50%) and 219 high risk (19.6%). Pelvic lymph node dissection was performed in 678 subjects (60.9%) of whom 79 (11.7%) had cancer invasion. In the surgical specimen, tumor extended beyond the capsule in 9.8% and invaded seminal vesicles in 11.8% of cases. Positive surgical margins (PSM) were detected in 271 cases (24.3%). The most frequently detected blood groups were A and O, which were equally distributed for both including 467 patients (41.9%), followed by groups B (127 cases; 11.4%) and AB (53 subjects; 4.8%). Among specimen factors, the ABO-bgs associated only with the risk of PSM, which was higher for blood group O (30.4%) compared with group A (19.5%) after adjusting for other standard clinical predictors (odds ratio, OR = 1.842; 95% CI 1.352–2.509; p < 0.0001). Along the ABO-bgs, the risk of PSM was increased by group O independently by other standard preoperative factors. The ABO-bgs may represent a further physical factor for clinical assessment of PCa patients, but confirmatory studies are required.

A Systematic Review of the Impact of Surgeon and Hospital Caseload Volume on Oncological and Nononcological Outcomes After Radical Prostatectomy for Nonmetastatic Prostate Cancer. Eur Urol 2021; 80:531-545. [PMID: 33962808 DOI: 10.1016/j.eururo.2021.04.028] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Accepted: 04/19/2021] [Indexed: 12/13/2022]
Abstract
CONTEXT The impact of surgeon and hospital volume on outcomes after radical prostatectomy (RP) for localised prostate cancer (PCa) remains unknown. OBJECTIVE To perform a systematic review on the association between surgeon or hospital volume and oncological and nononcological outcomes following RP for PCa. EVIDENCE ACQUISITION Medline, Medline In-Process, Embase, and the Cochrane Central Register of Controlled Trials were searched. All comparative studies for nonmetastatic PCa patients treated with RP published between January 1990 and May 2020 were included. For inclusion, studies had to compare hospital or surgeon volume, defined as caseload per unit time. Main outcomes included oncological (including prostate-specific antigen persistence, positive surgical margin [PSM], biochemical recurrence, local and distant recurrence, and cancer-specific and overall survival) and nononcological (perioperative complications including need for blood transfusion, conversion to open procedure and within 90-d death, and continence and erectile function) outcomes. Risk of bias (RoB) and confounding assessments were undertaken. Both a narrative and a quantitative synthesis were planned if the data allowed. EVIDENCE SYNTHESIS Sixty retrospective comparative studies were included. Generally, increasing surgeon and hospital volumes were associated with lower rates of mortality, PSM, adjuvant or salvage therapies, and perioperative complications. Combining group size cut-offs as used in the included studies, the median threshold for hospital volume at which outcomes start to diverge is 86 (interquartile range [IQR] 35-100) cases per year. In addition, above this threshold, the higher the caseload, the better the outcomes, especially for PSM. RoB and confounding were high for most domains. CONCLUSIONS Higher surgeon and hospital volumes for RP are associated with lower rates of PSMs, adjuvant or salvage therapies, and perioperative complications. This association becomes apparent from a caseload of >86 (IQR 35-100) per year and may further improve hereafter. Both high- and low-volume centres should measure their outcomes, make them publicly available, and improve their quality of care if needed. PATIENT SUMMARY We reviewed the literature to determine whether the number of prostate cancer operations (radical prostatectomy) performed in a hospital affects the outcomes of surgery. We found that, overall, hospitals with a higher number of operations per year have better outcomes in terms of cancer recurrence and complications during or after hospitalisation. However, it must be noted that surgeons working in hospitals with lower annual operations can still achieve similar or even better outcomes. Therefore, making hospital's outcome data publicly available should be promoted internationally, so that patients can make an informed decision where they want to be treated.

Abstract
Purpose: To present multinational experience in robot-assisted radical prostatectomy (RARP) by fellowship-trained expertise in low-volume regions in Gulf Cooperation Council (GCC) countries and to compare the current results with global outcomes reported in recent meta-analyses. Methods: A retrospective review of prospectively collected data was performed for patients undergoing RARP for localized prostate cancer (PCa). Three fellowship-trained surgeons at four academic and referral centers in Saudi Arabia and Kuwait performed all procedures between February 2014 and December 2019. Data on demographics, perioperative characteristics, pathology, and adverse events were collected. Results: A total of 207 patients were included with a median (IQR) follow-up duration of 28 (15-38) months. The median prostate volume and prostate-specific antigen were 42 (32-53) g and 9.1 (5.8-14.1) ng/mL, respectively. While 65.2% of patients had a Gleason score ≥7, 20% had grade group 4 disease, and 7.8% had ≥cT3 disease. The mean ± SD operative time was 203 ± 52 minutes, and the mean estimated blood loss was 158 ± 107 mL. Only 4 (1.9%) patients received perioperative blood transfusions. Positive surgical margins were observed in 21.7% of patients, all of whom had ≥pT3 disease. There were 23 complications in 18 (8.7%) patients, including Clavien-Dindo grade III complications in 2.4%. At the 12-month follow-up, 35.8% of patients were potent, 94.6% were continent, and 9.2% had biochemical recurrence. Conclusions: The safety and efficacy of RARP by fellowship-trained expertise in GCC countries were well established. The outcomes seem promising and comparable to international centers and should improve with increasing case volume and fellowship-trained expertise.

Front Oncol 2021; 10:539592. [PMID: 33628724 PMCID: PMC7897672 DOI: 10.3389/fonc.2020.539592] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 12/22/2020] [Indexed: 01/11/2023] Open
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 Current results concerning the effect of body mass index (BMI) on positive surgical margins (PSMs) after robot-assisted radical prostatectomy (RARP) in patients with localized prostate cancer are inconsistent. Therefore, the aim of this study was to further analyse the association between BMI and PSMs after RARP. Material and methods Between March 2017 and December 2017 a multicentre, prospective, randomised, single-blind series with a blinded outcome assessment of 232 RARP patients was performed. Multivariate logistical regression models were used to analyse the independent effect of obesity, with body-mass-index (BMI) dichotomised at 30 kg/m2 (model-1) and at 90th percentile (model-2), on PSMs. Results Median BMI was 27.2 kg/m2, PSMs were found in 15.5% (n = 36). In multivariate model-1, obesity did not have a significant effect on PSMs (OR 2.34, p = 0.061). However, if BMI was dichotomized at the 90th percentile (BMI ≥33.7 kg/m²), patients with a higher BMI showed PSMs four-times more frequently (OR 3.99, p = 0.013). In both models, preoperative prostate-specific antigen (PSA) levels and pathological tumour stage had a significant effect on PSMs. There was no significant correlation between BMI and the extent of PSMs, nor a significant difference between the BMI groups and the localisation of PSMs. There was a higher percentage of posteriolateral PSM localisation in obese patients compared to patients with a BMI of less than 30 kg/m2 (58.3% and 25.3% of the localisations were posterolateral in obese and non-obese patients, respectively), however this effect was not statistically significant (p = 0.175). Conclusions In addition to a longer operation time and about twice as many complications, patients with a BMI of ≥33.7 kg/m² had a higher PSM rate after RARP. Differences in localization of PSMs in relation to obesity should be evaluated in future research.

The impact of extended pelvic lymph node dissection on the risk of hospital readmission within 180 days after robot assisted radical prostatectomy. World J Urol 2020; 38:2799-2809. [PMID: 31980875 DOI: 10.1007/s00345-020-03094-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Accepted: 01/10/2020] [Indexed: 10/25/2022] Open
Abstract
OBJECTIVE To evaluate the factors associated with the risk of hospital readmission after robot assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND) for prostate cancer (PCA) over a long term. MATERIALS AND METHODS The risk of readmission was evaluated by clinical, pathological, and perioperative factors. Skilled and experienced surgeons performed the procedures. Patients were followed for complications and hospital readmission for a period of six months. The logistic regression model and Cox's proportional hazards assessed the association of factors with the risk of readmission. RESULTS From January 2013 to December 2018, 890 patients underwent RARP; ePLND was performed in 495 of these patients. Hospital readmission was detected in 25 cases (2.8%); moreover, it was more frequent when RARP was performed with ePLND (4.4% of cases) than without (0.8% of patients). On the final multivariate model, ePLND was the only independent factor that was positively associated with the risk of hospital readmission (hazard ratio, HR = 5935; 95%CI 1777-19,831; p = 0.004). CONCLUSIONS Over the long term after RARP for PCA, the risk of hospital readmission is associated with ePLND. In patients who underwent RARP and ePLND, 4.4% of them had a readmission, compared to RARP alone, in which only 0.8% of cases had a readmission. When ePLND is planned for staging pelvic lymph nodes, patients should be informed of the increased risk of hospital readmission.

Linear extent of positive surgical margin impacts biochemical recurrence after robot-assisted radical prostatectomy in a high-volume center. J Robot Surg 2020; 14:663-675.

Abstract
The objective of this study is to evaluate if surgeon volume and stratifying positive surgical margins (PSM) into focal and non-focal may differentially impact the risk of biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP). Between January 2013 and December 2017, 732 consecutive patients were evaluated. The population included negative cases (control group) and PSM subjects (study group). PSMs were stratified as focal (≤ 1 mm) or non-focal (> 1 mm). A logistic regression model assessed the independent association of factors with the risk of PSM. The risk of BCR of PSM and other factors was assessed by Cox's multivariate proportional hazards. Overall, 192 (26.3%) patients had PSM focal in 133 patients; non-focal in 59 cases. Focal PSM was associated with the percentage of biopsy positive cores (BPC; OR 1.011; p = 0.015), extra-capsular extension (pT3a stage; OR 2.064; p = 0.016), seminal vesicle invasion (pT3b; OR 2.150; p = 0.010), body mass index (odds ratio, OR 0.914; p = 0.006), and high surgeon volume (OR 0.574; p = 0.006). BPC (OR 1.013; p = 0.044), pT3a (OR 4.832; p < 0.0001) and pT3b stage (OR 5.153; p = 0.001) were independent predictors of the risk of non-focal PSM. Surgeon volume was not a predictor of non-focal PSM (p = 0.224). Independent factors associated with the risk of BCR were baseline PSA (hazard ratio, HR 1.064; p = 0.004), BPC (HR 1.015; p = 0.027), ISUP biopsy grade group (BGG) 2/3 (HR 2.966; p 0.003) and BGG 4/5 (HR 3.122; p = 0.022) pathologic grade group 4/5 (HR 3.257; p = 0.001), pT3b (HR 2.900; p = 0.003), and non-focal PSM (HR 2.287; p = 0.012). Surgeon volume was not a predictor of BCR (p = 0.253). High surgeon volume is an independent factor that lowers the risk of focal PSM. Surgeon volume does not affect non-focal PSM and BCR. Negative as well as focal PSM are not associated with BCR.

Background: The aim of this study was to determine whether any clinical factors are independent predictors of positive surgical margins (PSM), and to assess the association of PSM and biochemical recurrence (BR) after robot-assisted radical prostatectomy (RARP). Methods: The population included cases with negative surgical margins (control group) and patients with PSM (study group). Tumor grade was evaluated according to the International Society of Urologic Pathology (ISUP) system. A logistic regression model assessed the independent association of factors with the risk of PSM. The risk of BR was assessed by Cox’s multivariate proportional hazards. Results: A total of 732 consecutive patients were evaluated. Extend pelvic lymph node dissection (ePLND) was performed in 342 cases (46.7%). Overall, 192 cases (26.3%) had PSM. The risk of PSM was positively associated with the percentage of biopsy positive cores (BPC; odds ratio, OR = 1.012; p = 0.004), extracapsular extension (pT3a; OR=2.702; p < 0.0001), invasion of seminal vesicle (pT3b; OR = 2.889; p < 0.0001), but inversely with body mass index (OR = 0.936; p = 0.021), and high surgeon volume (OR = 0.607; p = 0.006). Independent clinical factors associated with the risk of BR were baseline prostate-specific antigen (PSA; hazard ratio, HR = 1.064; p = 0.004), BPC (HR = 1.015; p = 0.027), ISUP biopsy grade group (BGG) 2/3 (HR = 2.966; p = 0.003), and BGG 4/5 (HR = 3.122; p = 0.022). Pathologic factors associated with the risk of BR were ISUP group 4/5 (HR = 3.257; p = 0.001), pT3b (HR = 2.900; p = 0.003), and PSM (HR = 2.096; p = 0.045). Conclusions: In our cohort, features related to host, tumor, and surgeon volume are associated with the risk of PSM, which is also an independent parameter predicting BR after RARP. The surgical volume of the operating surgeon is an independent factor that decreases the risk of PSM, and, as such, the risk of BR.

Abstract
Objectives: To evaluate clinicopathological and perioperative factors associated with the risk of focal and non-focal positive surgical margins (PSMs) after robot-assisted radical prostatectomy (RARP). Patients and methods: The study was retrospective and excluded patients who were under androgen-deprivation therapy or had prior treatments. The population included: negative SM cases (control group), focal and non-focal PSM cases (study groups). PSMs were classified as focal when the linear extent of cancer invasion was ≤1 mm and non-focal when >1 mm. The independent association of factors with the risk of focal and non-focal PSMs was assessed by multinomial logistic regression. Results: In all, 732 patients underwent RARP, from January 2013 to December 2017. An extended pelvic lymph node dissection was performed in 342 cases (46.7%). In all, 192 cases (26.3%) had PSMs, which were focal in 133 (18.2%) and non-focal in 59 (8.1%). Independent factors associated with the risk of focal PSMs were body mass index (odds ratio [OR] 0.914; P = 0.006), percentage of biopsy positive cores (BPC; OR 1.011; P = 0.015), pathological extracapsular extension (pathological tumour stage [pT]3a; OR 2.064; P = 0.016), and seminal vesicle invasion (pT3b; OR 2.150; P = 0.010). High surgeon volume was a protective factor in having focal PSM (OR 0.574; P = 0.006). Independent predictors of non-focal PSMs were BPC (OR 1,013; P = 0,044), pT3a (OR 4,832; P < 0.001), and pT3b (OR 5,153; P = 0.001). Conclusions: In high-volume centres features related to host, tumour and surgeon volume are factors that predict the risk of focal and non-focal PSMs after RARP.
