  • 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

    • 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
  • 2018
  • 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.

  • Intravesical instillations and cancer-specific survival in patients with primary carcinoma in situ of the urinary bladder
  • 2017
  • Ingår i: Scandinavian Journal of Urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 51:2, s. 124-129
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of this study was to evaluate the use of intravesical treatment and cancer-specific survival of patients with primary carcinoma in situ (CIS). Materials and methods: Data acquisition was based on the Swedish National Registry of Urinary Bladder Cancer by selecting all patients with primary CIS. The analysis covered gender, age, hospital type and hospital volume. Intravesical treatment and death due to bladder cancer were evaluated by multivariate logistic regression and multivariate Cox analysis, respectively. Results: The study included 1041 patients (median age at diagnosis 72 years) with a median follow-up of 65 months. Intravesical instillation therapy was given to 745 patients (72%), and 138 (13%) died from bladder cancer during the observation period. Male gender [odds ratio (OR) = 1.56, 95% confidence interval (CI) 1.13–2.17] and treatment at county (OR = 1.65, 95% CI 1.17–2.33), university (OR =2.12, 95% CI 1.48–3.03) or high-volume (OR = 1.92, 95% CI 1.34–2.75) hospitals were significantly associated with higher odds of intravesical instillations. The age category ≥80 years had a significantly lower chance of receiving intravesical therapy (OR = 0.44, 95% CI 0.26–0.74) and a significantly higher risk of dying from bladder cancer (hazard ratio = 3.03, 95% CI 1.71–5.35). Conclusion: Significantly more frequent use of intravesical treatment of primary CIS was found for males and for patients treated at county, university and high-volume hospitals. Age ≥80 years was significantly related to less intravesical treatment and poorer cancer-specific survival.
