Popis: | OBJECTIVES: To quantify the real-world survival benefit of re-resection vs no re-resection in patients diagnosed with T1 bladder cancer (BC) at the population level. PATIENTS AND METHODS: Retrospective population-wide observational cohort study based on pathology reports linked to health administrative data. We identified patients who were diagnosed with T1 BC in the province of Ontario (01/2001-12/2015) and used billing claims to ascertain whether they received re-resection within 2-10 weeks. The time-dependent effect of re-resection on survival outcomes was modelled by Cox proportional hazards regression (unadjusted and adjusted for numerous assumed patient- and surgeon-level confounding variables). Effect measures were presented as hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: We identified 7666 patients of which 2162 (28.7%) underwent re-resection after a median (interquartile range) time of 45 (35-56) days. Patients who received re-resection were less likely to die from any causes (HR 0.68, 95% CI 0.63-0.74, P |
