Background Although pathological factors remain the main determinate of survival for patients with bladder cancer, quality of surgical care is crucial for satisfactory outcomes. Using a validated quality score, we investigated the impact of surgical factors on the overall survival (OS), recurrence-free survival (RFS) and disease-specific survival (DSS) in patients with locally advanced and organ-confined disease (OCD). Retrospective review of IRCC database includes 2460 patients from 29 institutions across 11 countries. The final cohort included 1343 patients who underwent RARCs between 2005 and 2016. Patients with locally advanced disease (LAD) (> pT2 and/or N +) were compared with OCD (≤ pT2/N0). Validated Quality Cystectomy Score (QCS) based on four sets of quality metrics was used to compare surgical performance. Kaplan–Meier method was used to compute RFS, CSS and OS rates. Multivariable stepwise logistic regression was used to evaluate variables associated with RFS, DSS and OS. Results 48% had LAD. When compared to patients with OCD, they received neobladders less frequently (17% vs. 28%, p p = 0.05). Postoperatively, more patients in the LAD group received adjuvant chemotherapy (24% vs. 4%, p p p Conclusion Quality of surgical care can affect disease control and OS in patients with bladder cancer treated with robot-assisted radical cystectomy.

Radical cystectomy is the gold standard for nonmetastatic muscle invasive bladder cancer and for refractory nonmuscle invasive disease. Compared to open radical cystectomy, robot-assisted radical cystectomy has been shown to provide comparable early oncologic outcomes and improved perioperative outcomes. However, there is a paucity of data on long-term oncologic outcomes and concerns about a higher incidence of local recurrence after robot-assisted radical cystectomy. We report 10-year oncologic outcomes following robot-assisted radical cystectomy using a multinational database.We retrospectively reviewed the prospective International Robotic Cystectomy Consortium database. Consecutive patients who underwent robot-assisted radical cystectomy 10 years ago or earlier were included in analysis. Data were reviewed for demographics, and perioperative, pathological and oncologic outcomes. Kaplan-Meier curves were used to depict recurrence-free, disease specific and overall survival. Multivariate stepwise Cox regression models were applied to identify variables associated with recurrence-free, disease specific and overall survival.We identified 446 patients with a median age of 67 years (IQR 59-76). Of the patients 10% received neoadjuvant chemotherapy, 51% experienced any complication, 23% had high grade complications and 4% died within 3 months of robot-assisted radical cystectomy. Disease was pT3 or greater in 43% of patients and pN+ in 24% while a positive soft tissue surgical margin was observed in 7%. At a median followup of 5 years (IQR 2-10, maximum 14) local and distant recurrence had developed in 15% and 29% of patients, respectively. Ten-year recurrence-free, disease specific and overall survival rates were 59%, 65% and 35%, respectively. Patients with pT3 or greater and pN+ disease showed worse recurrence-free, disease specific and overall survival.Long-term oncologic outcomes, and recurrence rates and patterns after robot-assisted radical cystectomy seem comparable to those in open series. Advanced disease stage and positive surgical margins remain the main determinants of survival after radical cystectomy.

Objective To compare the perioperative outcomes of intracorporeal (ICUD) vs extracorporeal urinary diversion (ECUD) after robot-assisted radical cystectomy (RARC). Patients and methods We retrospectively reviewed the prospectively maintained International Robotic Cystectomy Consortium (IRCC) database. A total of 972 patients from 28 institutions who underwent RARC were included. Propensity score matching was used to match patients based on age, gender, body mass index (BMI), American Society of Anesthesiologists Score (ASA) score, Charlson Comorbidity Index (CCI) score, prior radiation and abdominal surgery, receipt of neoadjuvant chemotherapy, and clinical staging. Matched cohorts were compared. Multivariate stepwise logistic and linear regression models were fit to evaluate variables associated with receiving ICUD, operating time, 90-day high-grade complications (Clavien-Dindo Classification Grade ≥III), and 90-day readmissions after RARC. Results Utilisation of ICUD increased from 0% in 2005 to 95% in 2018. The ICUD patients had more overall complications (66% vs 58%, P = 0.01) and readmissions (27% vs 17%, P = 0.01), but not high-grade complications (21% vs 24%, P = 0.22). A more recent RC era and ileal conduit diversion were associated with receiving an ICUD. Higher BMI, ASA score ≥3, and receiving a neobladder were associated with longer operating times. Shorter operating time was associated with male gender, older age, ICUD, and centres with a larger annual average RC volume. Longer intensive care unit stay was associated with 90-day high-grade complications. Higher CCI score, prior radiation therapy, neoadjuvant chemotherapy, and ICUD were associated with a higher risk of 90-day readmissions. Conclusions Utilisation of ICUD has increased over the past decade. ICUD was associated with more overall complications and readmissions compared to ECUD, but not high-grade complications.

Objective To characterise the surgical feasibility and outcomes of robot-assisted radical cystectomy (RARC) for pathological T4 bladder cancer. Patients and Methods Retrospective evaluation of a prospectively maintained International Radical Cystectomy Consortium database was conducted for 1118 patients who underwent RARC between 2003 and 2012. We dichotomised patients based on pathological stage (≤pT3 vs pT4) and evaluated demographic, operative and pathological variables in relation to morbidity and mortality. Results In all, 1000 ≤pT3 and 118 pT4 patients were evaluated. The pT4 patients were older than the ≤pT3 patients (P = 0.001). The median operating time and blood loss were 386 min and 350 mL vs 396 min and 350 mL for p T4 and ≤pT3, respectively. The complication rate was similar (54% vs 58%; P = 0.64) among ≤pT3 and pT4 patients, respectively. The overall 30- and 90-day mortality rate was 0.4% and 1.8% vs 4.2% and 8.5% for ≤pT3 vs pT4 patients (P < 0.001), respectively. The body mass index (BMI), American Society of Anesthesiology score, length of hospital stay (LOS) >10 days, and 90-day readmission were significantly associated with complications in pT4 patients. Meanwhile, BMI, LOS >10 days, grade 3–5 complications, 90-day readmission, smoking, previous abdominal surgery and neoadjuvant chemotherapy were significantly associated with mortality in pT4 patients. On multivariate analysis, BMI was an independent predictor of complications in pT4 patients, but not for mortality. Conclusions RARC for pT4 bladder cancer is surgically feasible but entails significant morbidity and mortality. BMI was independent predictor of complications in pT4 patients.

What's known on the subject? and What does the study add? Lymph node dissection and it's extend during robot-assisted radical cystectomy varies based on surgeon related factors. This study reports outcomes of robot-assisted extended lymphadenectomy based on surgeon experience in both academic and private practice settings. Objective To evaluate the incidence of, and predictors for, extended lymph node dissection (LND) in patients undergoing robot-assisted radical cystectomy (RARC) for bladder cancer, as extendedLND is critical for the treatment of bladder cancer but the role of minimally invasive surgery for extended LND has not been well-defined in a multi-institutional setting. Patients and Methods Used the International Robotic Cystectomy Consortium (IRCC) database. In all, 765 patients who underwent RARC at 17 institutions from 2003 to 2010 were evaluated for receipt of extended LND. Patients were stratified by age, sex, clinical stage, institutional volume, sequential case number, and surgeon volume. Logistic regression analyses were used to correlate variables to the likelihood of undergoing extended LND. Results In all, 445 (58%) patients underwent extended LND. Among all patients, a median (range) of 18 (0–74) LNs were examined. High-volume institutions (≥100 cases) had a higher mean LN yield (23 vs 15, P < 0.001). On univariable analysis, surgeon volume, institutional volume, and sequential case number were associated with likelihood of undergoing extended LND. On multivariable analysis, surgeon volume [odds ratio (OR) 3.46, 95% confidence interval (CI) 2.37–5.06, P < 0.001] and institution volume [OR 2.65, 95% CI 1.47–4.78, P = 0.001) were associated with undergoing extended LND. Conclusions Robot-assisted LND can achieve similar LN yields to those of open LND after RC. High-volume surgeons are more likely to perform extended LND, reflecting a correlation between their growing experience and increased comfort with advanced vascular dissection.

OBJECTIVES To evaluate the effect of previous robot-assisted radical prostatectomy (RARP) case volume on the outcomes of robot-assisted radical cystectomy. Little is known regarding the effect of previous robotic surgical experience on the implementation and execution of robot-assisted radical cystectomy. METHODS Using the International Robotic Cystectomy Consortium database, 496 patients were identified who had undergone robot-assisted radical cystectomy by 21 surgeons at 14 institutions from 2003 to 2009. The surgeons were divided into 4 groups according to their previous RARP experience (150 cases). The overall operative time, blood loss, lymph node yield, pathologic stage, and surgical margin status were compared among the 4 groups using chi-square analysis. RESULTS The mean operative time was 386 minutes (range 178-827). The mean estimated blood loss was 408 mL (range 25-3500). The operative time and blood loss were both significantly associated with previous RARP experience (P < .001). The mean lymph node count was 17.8 nodes (range 0-68). Lymph node yield and increased pathologic stage were significantly associated with previous RARP experience (P < .001). Finally, 34 (7.0%) of the 482 patients had a positive surgical margin. Margin status was not significantly associated with previous RARP experience (P = .089). CONCLUSIONS Previous RARP case volume might affect the operative time, blood loss, and lymph node yield at robot-assisted radical cystectomy. In addition, surgeons with increased RARP experience operated on patients with more advanced tumors. Previous RARP experience, however, did not appear to affect the surgical margin status.

Background: Robot-assisted radical cystectomy (RARC) has evolved as a minimally invasive alternative to open radical cystectomy for patients with invasive bladder cancer. Objective: We sought to de. ne the learning curve for RARC by evaluating results from a multicenter, contemporary, consecutive series of patients who underwent this procedure. Design, setting, and participants: Utilizing the International Robotic Cystectomy Consortium database, a prospectively maintained and institutional review board-approved database, we identified 496 patients who underwent RARC by 21 surgeons at 14 institutions from 2003 to 2009. Measurements: Cut-off points for operative time, lymph node yield (LNY), estimated blood loss (EBL), and margin positivity were identified. Using specifically designed statistical mixed models, we were able to inversely predict the number of patients required for an institution to reach the predetermined cut-off points. Results and limitations: Mean operative time was 386 min, mean EBL was 408 ml, and mean LNY was 18. Overall, 34 of 482 patients (7%) had a positive surgical margin (PSM). Using statistical models, it was estimated that 21 patients were required for operative time to reach 6.5 h and 8, 20, and 30 patients were required to reach an LNY of 12, 16, and 20, respectively. For all patients, PSM rates of

Background: Complication reporting is highly variable and nonstandardized. Therefore, it is imperative to determine the surgical outcomes of major oncologic procedures. Objective: To describe the complications after robot-assisted radical cystectomy (RARC) using a standardized and validated reporting methodology. Design, setting, and participants: Using the International Robotic Cystectomy Consortium (IRCC) database, we identified 939 patients who underwent RARC, had available complication data, and had at least 90 d of follow-up. Outcome measurements and statistical analysis: Complications were analyzed and graded according to the Memorial Sloan-Kettering Cancer Center (MSKCC) system and were defined and stratified by organ system. Secondary outcomes included identification of preoperative and intraoperative variables predicting complications. Logistic regression models were used to define predictors of complications and readmission. Results and limitations: Forty-one percent (n = 387) and 48% (n = 448) of patients experienced a complication within 30 and 90 d of surgery, respectively. The highest grade of complication was grade 0 in 52%, grade 1-2 in 29%, and grade 3-5 in 19% patients. Gastrointestinal, infectious, and genitourinary complications were most common (27%, 23%, and 17%, respectively). On multivariable analysis, increasing age group, neoadjuvant chemotherapy, and receipt of blood transfusion were independent predictors of any and high-grade complications, respectively. Thirty and 90-d mortality was 1.3% and 4.2%, respectively. As a multi-institutional database, a disparity in patient selection, operating standards, postoperative management, and reporting of complications can be considered a major limitation of the study. Conclusions: Surgical morbidity after RARC is significant when reported using a standardized reporting methodology. The majority of complications are low grade. Strict reporting of complications is necessary to advocate for radical cystectomy (RC) and helps in patient counseling. (C) 2013 European Association of Urology. Published by Elsevier B.V.

Objectives Clinical outcome studies of prostaglandin E 1 (PGE 1 ) have shown a markedly decreased rate of palpable fibrosis and plaque formation. In this prospective study we investigate the potential of this agent to produce subclinical fibrotic changes. Methods Real-time high-resolution ultrasound scanning of the corpora was performed using a 7.5 to 10 MHz linear array transducer in 80 men on initiation of treatment with self-administered PGE 1 and at quarterly intervals during the course of follow-up (3 to 28 months). The dorsal portion of the penile shaft was scanned in the transverse and sagittal planes from base to glans for a side by side comparison of the cavernosal tissue, evaluating local abnormalities of tissue echogenicity. Results Palpable lesions were not detected in any men on quarterly follow-up examination. Thirteen (16.5%) men developed new echogenic foci not present on pretreatment scanning at the following locations: proximal corpus cavernosum, subcutaneous tissues, and corpus spongiosum. These changes were observed both as single and multiple lesions ranging in size from 1 to 10 mm. The presence of these findings was independent of the etiology of impotence, dose frequency, and duration of intracavernous therapy. Conclusions The significance of these subclinical changes is unknown but their low incidence should be recognized when considering long-term intracavernous therapy.

Positive surgical margins at radical cystectomy confer a poor prognosis. We evaluated the incidence and predictors of positive surgical margins in patients who underwent robot assisted radical cystectomy for bladder cancer.Using the International Robotic Cystectomy Consortium database we identified 513 patients who underwent robot assisted radical cystectomy, as done by a total of 22 surgeons at 15 institutions from 2003 to 2009. After stratification by age group, gender, pathological T stage, nodal status, sequential case number and institutional volume logistic regression was used to correlate variables with the likelihood of a positive surgical margin.Of the 513 patients 35 (6.8%) had a positive surgical margin. Increasing 10-year age group, lymph node positivity and higher pathological T stage were significantly associated with an increased likelihood of a positive margin (p = 0.010,0.001 and p0.001, respectively). Gender, sequential case number and institutional volume were not significantly associated with margin positivity. The rate of margin positive disease at cystectomy was 1.5% for pT2 or less, 8.8% for pT3 and 39% for pT4 disease.Positive surgical margin rates at robot assisted radical cystectomy for advanced bladder cancer were similar to those in open cystectomy series in a large, multi-institutional, prospective cohort. Sequential case number, a surrogate for the learning curve and institutional volume were not significantly associated with positive margins at robot assisted radical cystectomy.

Gonadoblastomas are known to be hormonally active tumors that occur in streak or dysgenetic gonads of patients with intersex abnormalities. Several reports document their ability to produce beta-human chorionic gonadotropin (HCG), but none have documented an elevated peripheral serum beta-HCG. We report on the case of a patient with pure gonadal dysgenesis with XY karyotype who was found to have an elevated peripheral serum beta-HCG after a positive pregnancy test. Knowledge of gonadoblastoma's potential to elevate serum beta-HCG levels may prevent unnecessary searches for other causes.
