  • Management and outcome of muscle-invasive bladder cancer with clinical lymph node metastases. A nationwide population-based study in the bladder cancer data base Sweden (BladderBaSe)
  • 2019
  • Ingår i: Scandinavian Journal of Urology. - : TAYLOR & FRANCIS LTD. - 2168-1805 .- 2168-1813. ; 53:5, s. 332-338

    • Purpose: To investigate the clinical management and outcome of patients with muscle-invasive bladder cancer with clinical lymph node involvement, using longitudinal nationwide population-based data. Methods: In the Bladder Cancer Data Base Sweden (BladderBaSe), treatment and survival in patients with urinary bladder cancer clinical stage T2-T4 N + M0 diagnosed between 1997 and 2014 was investigated. Patients ' characteristics were studied in relation to TNM classification, curative or palliative treatment, cancer-specific (CSS) and overall survival (OS). Age at diagnosis was categorised as <= 60, 61-70, 71-80 and >80 years, and time periods were stratified as follows: 1997-2001, 2002-2005, 2006-2010 and 2011-2014. Results: There were 786 patients (72% males) with a median age of 71 years (interquartile range = 64-79 years). The proportion of patients with high comorbidity increased over time. Despite similar low comorbidity, curative treatment was given to 44% and to 70% of those in older (>70 years) and younger age groups, respectively. Curative treatment decreased over time, but chemotherapy and cystectomy increased to 25% during the last time period. Patients with curative treatment had better survival compared to those with palliative treatment, both regarding CSS and OS in the whole cohort and in all age groups. Conclusions: The low proportion of older patients undergoing treatment with curative intent, despite no or limited comorbidity, indicates missed chances of treatment with curative intent. The reasons for an overall decrease in curative treatment over time need to be analysed and the challenge of coping with an increasing proportion of node-positive patients with clinically significant comorbidity needs to be met.

  • Period-specific mean annual hospital volume of radical cystectomy is associated with outcome and perioperative quality of care: a nationwide population-based study
  • 2019
  • Ingår i: Bju International. - : WILEY. - 1464-4096 .- 1464-410X. ; 124:3, s. 449-456
  • Tidskriftsartikel (refereegranskat)abstract
    • 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 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.

  • Treatment and prognosis of patients with urinary bladder cancer with other primary cancers: a nationwide population-based study in the Bladder Cancer Data Base Sweden (BladderBaSe)
  • 2020
  • Ingår i: Bju International. - : WILEY. - 1464-4096 .- 1464-410X.
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective To study how patients with urinary bladder cancer (UBC) with previous or concomitant other primary cancers (OPCs) were treated, and to investigate their prognosis. Patients And Methods Using nationwide population-based data in the Bladder Cancer Data Base Sweden (BladderBaSe), we analysed the probability of treatment with curative intent, and UBC-specific and overall survival (OS) in patients with UBC diagnosed in the period 1997-2014 with or without OPC. The analyses considered the patient's characteristics, UBC tumour stage at diagnosis, and site of OPC. Results There were 38 689 patients, of which 9804 (25%) had OPCs. Those with synchronous OPCs more often had T2 and T3 tumours and clinically distant disease at diagnosis than those with UBC only. Patients with synchronous prostate cancer, female genital cancer and lower gastro-intestinal cancer were more often treated with curative intent than patients with UBC only. When models of survival were adjusted for age at diagnosis, marital status, education, year of diagnosis, Charlson Comorbidity Index and T-stage, UBC-specific survival was similar to patients with UBC only, but OS was lower for patients with synchronous OPC, explained mainly by deaths in OPC primaries with a bad prognosis. Conclusions OPC is common in patients with UBC. Treatment for UBC, after or in conjunction with an OPC, should not be neglected and carries just as high a probability of success as treatment in patients with UBC only. The needs of patients with UBC and OPC, and optimisation of their treatment considering their complicated disease trajectory are important areas of research.

  • Survival after radiotherapy versus radical cystectomy for primary muscle-invasive bladder cancer : A Swedish nationwide population-based cohort study
  • 2019
  • Ingår i: ; 8:5, s. 2196-2204
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Studies of survival comparing radical cystectomy (RC) and radiotherapy for muscle-invasive bladder cancer have provided inconsistent results and have methodological limitations. The aim of the study was to investigate risk of death after radiotherapy as compared to RC.Methods: We selected patients with muscle-invasive urothelial carcinoma without distant metastases, treated with radiotherapy or RC from 1997 to 2014 in the Bladder Cancer Data Base Sweden (BladderBaSe) and estimated absolute and relative risk of bladder cancer death and all-cause death. In a group of patients, theoretically eligible for a trial comparing radiotherapy and RC, we calculated risk difference in an instrumental variable analysis. We have not investigated chemoradiotherapy as this treatment was not used in the study time period.Results: The study included 3 309 patients, of those 17% were treated with radiotherapy and 83% with RC. Patients treated with radiotherapy were older, had more advanced comorbidity, and had a higher risk of death as compared to patients treated with RC (relative risks of 1.5-1.6). In the "trial population," all-cause death risk difference was 6 per 100 patients lower after radiotherapy at 5 years of follow-up, 95% confidence interval -41 to 29.Conclusion(s): Patient selection between the treatments make it difficult to evaluate results from conventionally adjusted and propensity-score matched survival analysis. When taking into account unmeasured confounding by instrumental variable analysis, no differences in survival was found between the treatments for a selected group of patients. Further clinical studies are needed to characterize this group of patients, which can serve as a basis for future comparison studies for treatment recommendations.

  • Management and outcome of TaG3 tumours of the urinary bladder in the nationwide, population-based bladder cancer database Sweden (BladderBaSe)
  • Ingår i: Scandinavian Journal of Urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 53:4, s. 200-205
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To investigate the management of TaG3 tumours of the urinary bladder using nationwide population-based data in relation to the prevailing guidelines, patients’ characteristics, and outcome. Materials and methods: The Bladder Cancer Data Base Sweden (BladderBaSe), including data from the Swedish National Register for Urinary Bladder Cancer (SNRUBC), was used to study all patients with TaG3 bladder cancer diagnosed from 2008 to 2014. Patients were divided into the following management groups: (1) transurethral resection (TUR) only, (2) TUR and intravesical instillation therapy (IVIT), (3) TUR and second-look resection (SLR), and (4) TUR with both SLR and IVIT. Patient and tumour characteristics and outcome were studied. Results: There were 831 patients (83% males) with a median age of 74 years. SLR was performed more often on younger patients, on men, and less often in the Western and Uppsala/Örebro Healthcare regions. IVIT was performed more often with younger patients, with men, in the Western Healthcare region, and less often in the Uppsala/Örebro Healthcare region. Death from bladder cancer occurred in 6% of cases within a median of 29 months (0–84 months) and was lower in the TUR/IVIT and TUR/SLR/IVIT groups compared to the other two groups. Conclusion: In the present study, there was, according to the prevailing treatment guidelines, an under-treatment with SLR for older patients, women, and in some healthcare regions and, similarly, there was an under-treatment with IVIT for older patients. Cancer-specific survival and relative survival were lower in the TUR only group compared to the TUR/IVIT and TUR/SLR/IVIT groups.

  • Urinary bladder cancer treated with radical cystectomy: Perioperative parameters and early complications prospectively registered in a national population-based database
  • 2014
  • Ingår i: Scandinavian Journal of Urology. - London : Taylor & Francis. - 2168-1813 .- 2168-1805. ; 48:4, s. 334-340
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Cystectomy combined with pelvic lymph-node dissection and urinary diversion entails high morbidity and mortality. Improvements are needed, and a first step is to collect information on the current situation. In 2011, this group took the initiative to start a population-based database in Sweden (population 9.5 million in 2011) with prospective registration of patients and complications until 90 days after cystectomy. This article reports findings from the first year of registration. Material and methods. Participation was voluntary, and data were reported by local urologists or research nurses. Perioperative parameters and early complications classified according to the modified Clavien system were registered, and selected variables of possible importance for complications were analysed by univariate and multivariate logistic regression. Results. During 2011, 285 (65%) of 435 cystectomies performed in Sweden were registered in the database, the majority reported by the seven academic centres. Median blood loss was 1000 ml, operating time 318 min, and length of hospital stay 15 days. Any complications were registered for 103 patients (36%). Clavien grades 1-2 and 3-5 were noted in 19% and 15%, respectively. Thirty-seven patients (13%) were reoperated on at least once. In logistic regression analysis elevated risk of complications was significantly associated with operating time exceeding 318 min in both univariate and multivariate analysis, and with age 76-89 years only in multivariate analysis. Conclusions. It was feasible to start a national population-based registry of radical cystectomies for bladder cancer. The evaluation of the first year shows an increased risk of complications in patients with longer operating time and higher age. The results agree with some previously published series but should be interpreted with caution considering the relatively low coverage, which is expected to be higher in the future.

  • No increased risk of short-term complications after radical cystectomy for muscle-invasive bladder cancer among patients treated with preoperative chemotherapy : a nation-wide register-based study
  • Ingår i: World Journal of Urology. - : Springer. - 0724-4983 .- 1433-8726. ; 38:2, s. 381-388
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Preoperative chemotherapy is underused in conjunction with radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) due to concerns for complications and delay of surgery. Prospective data on short-term complications from population-based settings with frequent use of preoperative chemotherapy and standardised reporting of complications is lacking. Methods: We identified 1,340 patients who underwent RC between 2011 and 2015 in Sweden due to MIBC according to the Swedish Cystectomy Register. These individuals were followed through linkages to several national registers. Propensity score adjusted logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for complications and death within 90 days of surgery, comparing patients receiving preoperative chemotherapy or not. Results: Minimum two cycles of preoperative chemotherapy were given to 519 (39%) of the patients, who on average tended to be younger, have higher education, better physical status, and more advanced bladder cancer than patients not receiving chemotherapy. After adjusting for these and other parameters, there was no association between treatment with preoperative chemotherapy and short-term complications (OR 1.06 95% CI 0.82–1.39) or mortality (OR 0.75 95% CI 0.36–1.55). We observed a risk reduction for gastrointestinal complications among patients who received preoperative chemotherapy compared with those who did not (OR 0.49 95% CI 0.30–0.81). Conclusion: This nation-wide population-based observational study does not suggest that preoperative chemotherapy, in a setting with high utilisation of such treatment, is associated with an increased risk of short-term complications in MIBC patients treated with radical cystectomy.

  • Incidence, survival and mortality trends of bladder cancer in Sweden 1997–2016
  • 2019
  • Ingår i: Scandinavian Journal of Urology. - : TAYLOR & FRANCIS LTD. - 2168-1805 .- 2168-1813. ; 53:4, s. 193-199
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To evaluate trends in bladder cancer incidence, survival and mortality in Sweden from 1997–2016. Patients and methods: The Swedish National Registry of Urinary Bladder Cancer is a nation-wide quality register that started in 1997. It includes information on initial tumor characteristics and treatment; 41,097 new cases were registered up to 2016. Patients were stratified into four time periods. Deaths were monitored through the national death register. Overall and relative survival in time periods were studied with respect to differences in stage, age and gender. Results: The number of new cases increased by 38% for men and 39% for women from 1997 to 2016. The corresponding age-standardized incidence per 100,000 was less dramatic, with increases of 6% and 21%, respectively, and the increase was most evident in the oldest age group. The survival rate was stable until 2012, but thereafter a significant improvement occurred. The survival trends in stage-groups show that this improvement is found in all categories as well as irrespective of age and gender. The mortality rate during this period was stable for women, but showed a slight decrease for men. The main limitation of this study is the use of administrative data for defining some of the endpoints. Conclusion: The most recent Swedish bladder cancer statistics show an increased incidence, improved survival, but stable mortality. © 2019, © 2019 Acta Chirurgica Scandinavica Society.

  • Treatment according to guidelines may bridge the gender gap in outcome for patients with stage T1 urinary bladder cancer
  • Ingår i: Scandinavian Journal of Urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 52:3, s. 186-193
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of this investigation was to study differences between male and female patients with stage T1 urinary bladder cancer (UBC) regarding intravesical instillation therapy, second resection and survival. Materials and methods: This study included all patients with non-metastatic primary T1 UBC reported to the Swedish National Register of Urinary Bladder Cancer (SNRUBC) from 1997 to 2014, excluding those treated with primary cystectomy. Differences between groups were evaluated using chi-squared tests and logistic regression, and survival was investigated using Kaplan–Meier and log-rank tests and Cox proportional hazards analysis. Results: In all, 7681 patients with T1 UBC (77% male, 23% female) were included. Females were older than males at the time of diagnosis (median age at presentation 76 and 74 years, respectively; p < .001). A larger proportion of males than females underwent intravesical instillation therapy (39% vs 33%, p < .001). Relative survival was lower in women aged ≥75 years and women with G3 tumours compared to men. However, women aged ≥75 years who had T1G3 tumours and underwent second resection followed by intravesical instillation therapy showed a relative survival equal to that observed in men. Conclusions: This population-based study demonstrates that women of all ages with T1 UBC undergo intravesical instillation therapy less frequently than men, and that relative survival is poorer in women aged ≥75 years than in men of the same age when intravesical instillation therapy and second resection are not used. However, these disparities may disappear with treatment according to guidelines.

  • EGFR-expression in primary urinary bladder cancer and corresponding metastases and the relation to HER2-expression. On the possibility to target these receptors with radionuclides
  • 2015
  • Ingår i: Radiology and Oncology. - 1318-2099 .- 1581-3207. ; 49:1, s. 50-58
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. There is limited effect of tyrosine kinase inhibitors or "naked" antibodies binding EGFR or HER2 for therapy of metastasized urinary bladder canter and these methods are therefore not routinely used. Targeting radionuclides to the extracellular domain of the receptors is potentially a better possibility. Methods. EGFR- and HER2-expression was analyzed for primary tumors and corresponding metastases from 72 patients using immunohistochemistry and the internationally recommended HercepTest. Intracellular mutations were not analyzed since only the receptors were considered as targets and intracellular abnormalities should have minor effect on radiation dose. Results. EGFR was positive in 71% of the primary tumors and 69% of corresponding metastases. Local and distant metastases were EGFR-positive in 75% and 66% of the cases, respectively. The expression frequency of HER2 in related lesions was slightly higher (data from previous study). The EGFR-positive tumors expressed EGFR in metastases in 86% of the cases. The co-expression of EGFR and HER2 was 57% for tumors and 53% for metastases. Only 3% and 10% of the lesions were negative for both receptors in tumors and metastases, respectively. Thus, targeting these receptors with radionuclides might be applied for most patients. Conclusions. At least one of the EGFR- or HER2-receptors was present in most cases and co-expressed in more than half the cases. It is therefore interesting to deliver radionuclides for whole-body receptor-analysis, dosimetry and therapy. This can hopefully compensate for resistance to other therapies and more patients can hopefully be treated with curative instead of palliative intention.
