Objective: To describe the natural history of untreated muscle-invasive bladder cancer (MIBC) and compare the oncological outcomes of treated and untreated patients., Patients and Methods: We utilised a database encompassing all patients with newly diagnosed bladder cancer in Stockholm, Sweden between 1995 and 1996. The median follow-up for survivors was 14.4 years. Overall, 538 patients were diagnosed with bladder cancer of whom 126 had clinically localised MIBC. Patients were divided into two groups: those who received radical cystectomy or radiation therapy, and those who did not receive any form of treatment. Multivariable Cox or competing-risks regressions were adopted to predict metastasis, overall survival (OS), and cancer-specific mortality (CSM), when appropriate. Analyses were adjusted for age at diagnosis, sex, tumour stage, clinical N stage, and treatment., Results: In all, 64 (51%) patients did not receive any definitive local treatment. In the untreated group, the median (interquartile range) age at diagnosis was 79 (63-83) vs 69 (63-74) years in the treated group (P < 0.001). Overall, 109 patients died during follow-up. At 6 months after diagnosis, 38% of the untreated patients had developed metastatic disease and 41% had CSM. The 5-year OS rate for untreated and treated patients was 5% (95% confidence interval [CI] 1, 12%) vs 48% (95% CI 36, 60%), respectively. Patients not receiving any treatment had a 5-year cumulative incidence of CSM of 86% (95% CI 75, 94%) vs 48% (95% CI 36, 60%) for treated patients. Untreated patients had a higher risk of progression to metastatic disease (hazard ratio [HR] 2.40, 95% CI 1.28, 4.51; P = 0.006), death from any cause (HR 2.63, 95% CI 1.65, 4.19; P < 0.001) and CSM (subdistribution HR 2.02, 95% CI 1.24, 3.30; P = 0.004)., Conclusions: Untreated patients with MIBC are at very high risk of near-term CSM. These findings may help balance the risks vs benefits of integrating curative intent therapy particularly in older patients with MIBC., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)

Objective: To investigate the association between hospital volume and overall survival (OS), cancer-specific survival (CSS), and quality of care of patients with bladder cancer who undergo radical cystectomy (RC), defined as the use of extended lymphadenectomy (eLND), continent reconstruction, neoadjuvant chemotherapy (NAC), and treatment delay of <3 months., Patients and Methods: We used the Bladder Cancer Data Base Sweden (BladderBaSe) to study survival and indicators of perioperative quality of care in all 3172 patients who underwent RC for primary invasive bladder cancer stage T1-T3 in Sweden between 1997 and 2014. The period-specific mean annual hospital volume (PSMAV) during the 3 years preceding surgery was applied as an exposure and analysed using univariate and multivariate mixed models, adjusting for tumour and nodal stage, age, gender, comorbidity, educational level, and NAC. PSMAV was either categorised in tertiles, dichotomised (at ≥25 RCs annually), or used as a continuous variable for every increase of 10 RCs annually., Results: PSMAV in the highest tertile (≥25 RCs annually) was associated with improved OS (hazard ratio [HR] 0.87, 95% confidence interval [CI] 0.75-1.0), whereas the corresponding HR for CSS was 0.87 (95% CI 0.73-1.04). With PSMAV as a continuous variable, OS was improved for every increase of 10 RCs annually (HR 0.95, 95% CI 0.90-0.99). Moreover, higher PSMAV was associated with increased use of eLND, continent reconstruction and NAC, but also more frequently with a treatment delay of >3 months after diagnosis., Conclusions: The current study supports centralisation of RC for bladder cancer, but also underpins the need for monitoring treatment delays associated with referral., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)

Objective: To evaluate the risk of different in-hospital complications for patients undergoing a radical cystectomy (RC), as limited nationwide population data on short- and long-term complications after RC is available, despite it being the standard treatment for localised muscle-invasive urinary bladder cancer (UBC)., Patients and Methods: In all, 7608 persons underwent a RC after UBC diagnosis, as registered in the Swedish National Patient Register between 1964 and 2008. We estimated the frequency and incidences and calculated hazard ratios (HR) and 95% confidence intervals (CI) using multivariate Cox proportional hazards models., Results: Urinary tract infection/septicaemia was the most common complication following radical cystectomy, with an incidence of 90.4 per 1,000 person years. There was a higher risk of urinary tract infection among patients who had a continent cutaneous reservoir (HR: 1.11 (0.94-1.30) or orthotopic neobladder 1.21 (1.05-1.39) than among those with ileal conduit. Similarly, continent cutaneous reservoir and orthotopic neobladder were associated with increased risks for wound and abdominal wall hernias, stones in the urinary tract, hydronephrosis and nephrostomy tube treatment, and kidney failure. In contrast, risk of bowel obstruction was lower among those with orthotopic neobladder than those with ileal conduit (HR: 0.64 (0.50-0.81)) and those with continent cutaneous reservoir (HR: 0.92 (0.73-1.16)., Conclusions: In-hospital complications after RC are numerous and continue to accumulate for many years after surgery, indicating the need for life-long follow-up of these patients. Comparison between different types of diversion should, however, be made with care because of potential confounding by indication., (© 2013 The Authors.

Objective: This study evaluated the impact of hospital volume on local recurrence and distant metastasis in a population-based series of radical cystectomy patients in Sweden., Material and Methods: All patients who underwent cystectomy for bladder cancer in 1997-2002 in Sweden and were reported to the National Bladder Cancer Registry were included. A high-volume hospital (HVH) was defined as one with ≥10 cystectomies/year and a low-volume hospital (LVH) as one with <10 cystectomies/year. Information on preoperative tumour, node, metastasis (TNM) classification, operative procedure, postoperative course and follow-up was obtained from medical records., Results: Of the 1126 patients, 827 (74%) were males. The mean age was 66 years and median follow-up 47 months. Of the 610 (54%) HVH patients, 68 (11%) were pT0, 123 (20%) < pT2, 177 (29%) pT2, 242 (40%) > pT2 and 69 (11%) were microscopic non-radical. Corresponding figures for the 516 (46%) LVH patients were 35 (7%), 68 (13%), 191 (37%), 222 (43%) and 96 (19%). Local recurrence was observed in 245 patients (22%): 113 (19%) at HVHs and 132 (26%) at LVHs. Distant metastasis was found in 363 (32%): 203 (33%) at HVHs and 160 (31%) at LVHs. Perioperative chemotherapy was given to 193 (17%). Multivariate Cox proportional hazards analysis showed that local recurrence was associated with LVHs and non-organ-confined disease, whereas distant metastasis was correlated with non-organ-confined disease and lymph-node metastases., Conclusions: In this retrospective analysis, local tumour recurrence after cystectomy was common, particularly in patients with non-organ-confined disease. Furthermore, local recurrence was more frequent at LVHs than HVHs, and overall survival was better at HVHs. These findings suggest that concentrating cystectomies in HVHs may improve outcomes such as local recurrence and overall survival.

Background: Robot-assisted radical cystectomy (RARC) may reduce morbidity after cystectomy. Descriptions of the surgical techniques of RARC with intracorporeal orthotopic neobladder or ileal conduit are sparse and oncologic and functional outcome data have not been reported., Objective: We present our technique with RARC and intracorporeal urinary diversion (neobladder or ileal conduit) and present oncologic and functional outcomes, as well as complication rates., Design, Setting, and Participants: Single-hospital institution case-series from 2004 to 2009 including 45 selected patients (38 male, 7 female) with high-grade and/or muscle-invasive urothelial cancer of the bladder., Surgical Procedure: We performed RARC; pelvic lymph node dissection using three different templates; and a totally intracorporeal urinary diversion, either orthotopic neobladder (n=36) or ileal conduit (n=9)., Measurements: Perioperative variables, pathology data, early and late complication rates, urinary continence, potency, and cancer-specific survival were evaluated as outcome measures., Results and Limitations: Median patient age, operative time, estimated blood loss, and lymph node yield were 62 yr (range: 37-79), 477 min (range: 325-760), 550 ml (range: 200-2200), and 19 (range: 10-52), respectively. Nine patients were diagnosed with positive lymph nodes. Surgical margins were clear in all but one patient. Early complications occurred in 18 patients (40%). Median postoperative stay was 9 d (range: 4-78), and median postoperative follow-up time was 25 mo. Four patients died due to metastatic disease. The study is limited by a relative small sample size and no comparative group., Conclusions: RARC with totally intracorporeal urinary diversion is technically feasible with good intermediate-term oncologic results. This is a nonrandomised study including a limited number of patients with a restricted follow-up time, however, and so precautions must be considered when interpreting the outcomes., (Copyright © 2011 European Association of Urology.

Purpose: We studied treatment delay, and the impact on disease specific survival and stage progression in a series of patients who had undergone cystectomy., Materials and Methods: All 141 patients underwent radical cystectomy between 1990 and 1997 due to locally advanced bladder cancer. Treatment delay was defined as time from pathological confirmation of invasive disease to performance of cystectomy, and was registered retrospectively from the patient charts. Two patients received neoadjuvant chemotherapy and were excluded from further analyses. Followup continued until April 2003 with death due to bladder cancer as the end point. Causes of death were retrieved from the Swedish Cause of Death Registry., Results: The median treatment delay was 49 days, but was significantly longer for the 71 cases who were referred from other hospitals (63 vs 41 days, p < 0.001). Treatment delay did not influence cumulative incidence of death from bladder cancer. Considering all cases, there was no significant correlation between treatment delay and stage progression. For clinical stage T2 tumors, median treatment delay was 76 days among patients with stage progression compared to 41 and 48 days for those with stage regression and stage equivalence, respectively (p = 0.20)., Conclusions: Treatment delay was not found to influence disease specific survival in the present study. Furthermore, treatment delay was not significantly longer in cases that progressed compared to those with equal or lower pathological stage in the cystectomy specimen.
