Cancer-specific survival by stage of bladder and urinary tract cancers and factors collected by Mallorca Cancer Registry associated to survival.
Abstract Background: Information about survival by stage in bladder cancer is scarce. Objectives: 1) to find out the distribution of bladder and urinary tract cancers by stage; 2) to determine cancer-specific survival by stage of bladder and urinary tract cancers; 3) to identify factors that explain and predict the likelihood of survival and the risk of dying from these cancers.Methods: Incident bladder and urinary tract cancer cases diagnosed between 2006 and 2011 were identified through the Mallorca Cancer Registry. Inclusion criteria: cases with codes C65–C68 (ICD-O 3) with any behaviour. DCO cases were excluded. We collected: sex; age; date and method of diagnosis; histology (ICD-O 3); T, N, M and stage at the time of diagnosis; and date of follow-up or death. End of follow up was 31 December 2015. Multiple imputation (MI) was performed to estimate cases with unknown stage. Actuarial and Kaplan-Meier methods and Cox regression models were used.Results: 2060 cases were identified. 15% were women and 65.2% were 65 years or older. 3.7% had no stage (benign or undetermined behaviour) and 12.5% had unknown stage. After MI, 35.7% were in stage Ta (non-invasive papillary carcinoma), 3.1% in stage Tis (carcinoma in situ), 33.3% in stage I, 11.9 % in Stage II, 4.7% in stage III, and 11.1% in stage IV. Survival was 73% at 5 years. Survival by stage: 98% at stage Ta, 88% at stage Tis, 84% at stage I, 44% at stage II, 33% at stage III, and 7% at stage IV. The Cox model showed that age, histology, and stage were associated with survival.Conclusion: Bladder and urinary tract cancers survival vary greatly with stage. The percentage of non-invasive cancers was high. Stage, age and histology are associated to survival, but sex has no association..
