  • 2023
  • Ingår i: Ejso. - : Elsevier BV. - 0748-7983 .- 1532-2157. ; 49:4, s. 868-874

    • Introduction: We aimed to compare short term outcomes after robot assisted radical cystectomy (RARC) and open radical cystectomy (ORC) for urinary bladder cancer in a large population.Materials and methods: We included all patients without distant metastases who underwent either RARC or ORC with ileal conduit between 2011 and 2019 registered in the Bladder cancer data Base Sweden (BladderBaSe) 2.0. Primary outcome was unplanned readmissions within 90 days, and secondary out-comes within 90 days of surgery were reoperations, Clavien 3-5 complications, total days alive and out of hospital, and mortality. The analysis was carried out using multivariate regression models.Results: Out of 2905 patients, 832 were operated with RARC and 2073 with ORC. Robotic procedures were to a larger extent performed during later years, at high volume centers (47% vs 17%), more often for organ-confined disease (82% vs. 72%) and more frequently in patients with high socioeconomic status (26% vs. 21%). Patients operated with RARC were more commonly readmitted (29% vs. 25%). In multi -variable analysis RARC was associated with decreased risk of Clavien 3-5 complications (OR 0.58, 95% CI 0.47-0.72), reoperations (OR 0.53, 95% CI 0.39-0.71) and had more days alive and out of hospital (mean difference 3.7 days, 95% CI 2.4-5.0).Conclusion: This study illustrates the "real-world" effects of a gradual and nation-wide introduction of RARC. Patients operated with RARC had fewer major complications and reoperations but were more frequently readmitted compared to ORC. The observed differences were largely due to more wound related complications among patients treated with ORC.(c) 2023 The Authors. Published by Elsevier Ltd.

  • Number of transurethral procedures after non-muscle-invasive bladder cancer and survival in causes other than bladder cancer
  • 2022
  • Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 17:9 September
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Previous research has associated repeated transurethral procedures after a diagnosis of non-muscle invasive bladder cancer (NMIBC) with increased risk of death of causes other than bladder cancer. Aim We investigated the overall and disease-specific risk of death in patients with NMIBC compared to a background population sample. Methods We utilized the database BladderBaSe 2.0 containing tumor-specific, health-related and socio-demographic information for 38,547 patients with NMIBC not primarily treated with radical cystectomy and 192,733 individuals in a comparison cohort, matched on age, gender, and county of residence. The cohorts were compared using Kaplan-Meier curves and Hazard ratios (HR) from a Cox regression models. In the NMIBC cohort, we analyzed the association between number of transurethral procedures and death conditioned on surviving two or five years. Results Overall survival and survival from causes other than bladder cancer estimated with Kaplan- Meier curves was 9.3% (95% confidence interval (CI) (8.6%-10.0%)) and 1.4% (95% CI 0.7%-2.1%) lower respectively for the NMIBC cohort compared to the comparison cohort at ten years. In a Cox model adjusted for prognostic group, educational level and comorbidity, the HR was 1.03 (95% CI 1.01-1.05) for death from causes other than bladder cancer comparing the NMIBC cohort to the comparison cohort. Among the NMIBC patients, there was no discernible association between number of transurethral procedures and deaths of causes other than bladder cancer after adjustment. The number of procedures were, however, associated with risk of dying from bladder cancer HR 3.56 (95% CI 3.43-3.68) for four or more resections versus one within two years of follow-up. Conclusion The results indicate that repeated diagnostic or therapeutic transurethral procedures under follow-up do not increase of risk dying from causes other than bladder cancer. The modestly raised risk for NMIBC patients dying from causes other than bladder cancer is likely explained by residual confounding. © 2022 Holmberg et al.

  • Cohort profile: Bladder Cancer Data Base Sweden (BladderBaSe) 2.0
  • 2022
  • Ingår i: Bmj Open. - : BMJ. - 2044-6055. ; 12:12
  • Tidskriftsartikel (refereegranskat)abstract
    • PurposeWe constructed Bladder Cancer Data Base Sweden (BladderBaSe) 2.0 to expand studies in BladderBaSe on incidence, treatment outcomes, side effects, survival and health economic aspects of men and women with cancer in the urinary bladder, upper tract urothelial carcinoma (UTUC) (renal pelvis and ureter) and urethral carcinoma.ParticipantsBladderBaSe 2.0 includes 53 298 patients with cancer in the urinary bladder, diagnosed from 1 January 1997 to 31 December 2019, and 961 patients with UTUC in the renal pelvis and 792 in the ureter, and 146 patients with urethral urothelial carcinoma, diagnosed from 1 January 2015 to 31 December 2019, and in total 275 816 participants in reference groups, free of cancer in the urinary tract, matched 1:5 on sex, age and county.Findings to dateTo date, 18 published studies based on data from the BladderBaSe have investigated calendar time trends in survival; impact of gender, socioeconomic factors, tumour aggressiveness and hospital volume for radical cystectomy on prognosis; survival after radical cystectomy compared with radical radiotherapy; risk factors for complications and side effects after radical cystectomy such as thromboembolism, strictures of ureteroenterostomies and incisional hernia.Future plansThe BladderBaSe initiators are currently investigating gender-dependent detection delays due to urinary tract infections; survival after non-muscle invasive bladder cancer with respect to the number of transurethral resections; short-term outcomes comparing open and robot-assisted radical cystectomy; studies on risk for intravesical recurrence after different diagnostic measures in UTUC, and suicide risk after bladder cancer diagnosis. The BladderBaSe project group is open for collaborations with national and international colleagues.

  • Preoperative upper tract invasive diagnostic modalities are associated with intravesical recurrence following surgery for upper tract urothelial carcinoma: A population-based study
  • 2023
  • Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 18:2
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundIntravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from urothelial cancer and all causes was investigated as secondary outcomes. MethodsWe investigated a population-based cohort of 1038 consecutive patients subjected to radical surgery for UTUC 2015-2019 in Sweden, using the Bladder Cancer Data Base Sweden (BladderBaSe 2.0), comprising all patients in the Swedish National Registry of Urinary Bladder Cancer. Risk estimates of IVR, death from urothelial cancer, and all causes was assessed using multivariable Cox regression models. ResultsThe study included 536 cases with and 502 without preoperative IDM. IDM was associated with increased risk of IVR (HR 1.24, 95% CI 1.03-1.52) and risk of urothelial cancer death (HR 1.56, CI 1.12-2.18), compared to no IDM after a median follow-up of 1.3 yrs. Stratified analysis for tumor location showed that IDM was associated with risk of IVR in ureteric cancer (HR 1.66, 95% CI 1.21-2.28) but not in renal pelvic cancer (HR 1.07, 95% CI 0.81-1.41). Limitations included the observational setting and the lack of variables such as tumour grade, multifocality and preoperative hydronephrosis. ConclusionsWorse outcomes for patients subjected to preoperative IDM highlight the need for carefully considering diagnostic decisions for UTUC patients, specifically in tumours located in the ureter.

  • 2021
  • Ingår i: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 55:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective For patients undergoing radical cystectomy for bladder cancer, a procedure requiring complex urinary tract reconstruction prone to major postoperative complications, the timing and quality of the surgery have been associated with outcomes. Patients and methods This study investigated if radical cystectomy for bladder cancer performed during holiday periods had worse disease-specific (DSS) and overall survival (OS), higher 90-day mortality and risk of readmissions. All patients operated on with radical cystectomy for primary bladder cancer during 1997-2014 with holiday periods as exposure (with one narrow (7 weeks) and one wider (14 weeks) definition) in the Swedish population-based bladder cancer research-database (BladderBaSe) were studied. DSS and OS after radical cystectomy during holiday periods were analysed with Cox regression models adjusted for sex, age, comorbidity, marital status, T-stage and nodal metastases, neoadjuvant chemotherapy, hospital volume and year of cystectomy. Results Surgery during the holiday periods (narrow and wide definitions) were not associated with DSS (Hazard ratio [HR] = 1.05, 95% confidence interval [95% CI] = 0.90-1.21 and HR = 1.04, 95% CI = 0.91-1.17), respectively. HRs for OS were similar, and no associations between radical cystectomy during any of the holiday period definitions and 90-day mortality and readmission were found. Conclusion Survival after radical cystectomy in Sweden is similar during holiday and non-holiday periods.

  • Swedish National Guidelines on Urothelial Carcinoma: 2021 update on non-muscle invasive bladder cancer and upper tract urothelial carcinoma
  • 2022
  • Ingår i: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 56:2, s. 137-146
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To overview the updated Swedish National Guidelines on Urothelial Carcinoma 2021, with emphasis on non-muscle-invasive bladder cancer (NMIBC) and upper tract urothelial carcinoma (UTUC). Methods: A narrative review of the updated version of the Swedish National Guidelines on Urothelial Carcinoma 2021 and highlighting new treatment recommendations, with comparison to the European Association of Urology (EAU) guidelines and current literature. Results: For NMIBC the new EAU 2021 risk group stratification has been introduced for non-muscle invasive bladder cancer to predict risk of progression and the web-based application has been translated to Swedish (https://nmibc.net.). For patients with non-BCG -responsive disease treatment recommendations have been pinpointed, to guide patient counselling in this clinical situation. A new recommendation in the current version of the guidelines is the introduction of four courses of adjuvant platinum-based chemotherapy to patients with advanced disease in the nephroureterectomy specimen (pT2 or higher and/or N+). Patients with papillary urothelial neoplasms with low malignant potential (PUNLMP) can be discharged from follow-up already after 3 years based on a very low subsequent risk of further recurrences. Conclusions: The current version of the Swedish national guidelines introduces a new risk-stratification model and follow-up recommendation for NMIBC and adjuvant chemotherapy after radical surgery for UTUC.

  • Cumulative incidence of ureteroenteric strictures after radical cystectomy in a population-based Swedish cohort
  • 2021
  • Ingår i: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 55:5, s. 361-365
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective The incidence of benign ureteroenteric strictures following radical cystectomy (RC) for urinary bladder cancer (UBC) is investigated mainly in single-centre studies from high-volume centres. The aim of this study was to evaluate the cumulative incidence of strictures and risk factors in a population-based cohort. Patients and methods Data was collected from Bladder Cancer Data Base Sweden (BladderBaSe). The primary endpoint was stricture with intervention. Secondary endpoint included hydronephrosis both with/without intervention. Results In total, 5,816 patients were registered as having had RC due to UBC between 1997 and 2014. After a median follow-up of 23.5 months (IQR = 9.0-63.1 months; range = 0.0-214.0 months), we found that 515 (8.9%) patients underwent intervention for stricture. Seven hundred and sixty-one (13.1%) patients were diagnosed with hydronephrosis without intervention. The cumulative incidence of strictures with intervention was 19.7% (95% CI = 16.7-23.1%) during the 17 years of follow-up. In the first year, the cumulative incidence of strictures was 5.6% (95% CI = 5.0-6.2%), and in the first 2 years 8.4% (95% CI = 7.6-9.3%). For the secondary endpoint, the cumulative incidence was 30.4% (95% CI = 26.7-33.1%) after 17 years. Only the year of RC was associated with stricture incidence in Cox regression analysis, whereas hospital cystectomy volume, patient age and patient sex were not. Conclusion Ureteroenteric strictures requiring intervention may be more common than previously reported, affecting nearly one fifth of patients who have undergone RC for UBC. The annual incidence was highest in the first 2 years after surgery but the cumulative incidence increased continuously during 17 years of follow-up.

  • Risk of bladder cancer death in patients younger than 50 with non-muscle-invasive and muscle-invasive bladder cancer
  • 2022
  • Ingår i: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 56:1, s. 27-33
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction and objectives Bladder cancer is primarily a disease of older age and little is known about the differences between patients diagnosed with bladder cancer at a younger versus older age. Our objectives were to compare bladder cancer specific survival in patients aged Materials and methods The Swedish bladder cancer database provided data on patient demographics, clinical characteristics and treatments for this observational study. Cox proportional hazard regression models were adjusted for appropriate variables. All analyses were stratified by disease stage (non-muscle-invasive bladder cancer and muscle-invasive bladder cancer. Furthermore, we compared the frequency of lower urinary tract infections within 24 months prior to bladder cancer diagnosis by sex and age groups. Results The study included 15,452 newly-diagnosed BC patients (1997-2014); 1,207 (8%) patients were <50 whilst 14,245 (92%) were aged 50-70. Patients aged <50 at diagnosis were at a decreased risk of bladder cancer death (HR = 0.82, 95%CI: 0.68-0.99) compared to those aged 50-70. When stratified by non-muscle-invasive and muscle-invasive bladder cancer, this association remained in non-muscle-invasive patients only (<50, HR = 0.43, 95% CI: 0.28-0.64). The frequency of lower urinary tract infection diagnoses did not differ between younger and older patients in either men or women. Conclusions Patients diagnosed with non-muscle-invasive bladder cancer when aged <50 are at decreased risk of bladder cancer-specific death when compared to their older (50-70) counterparts. These observations raise relevant research questions about age-related differences in diagnostic procedures, clinical decision-making and, not least, potential differences in tumour biology.
