Risk of bladder cancer death in patients younger than 50 with non-muscle-invasive and muscle-invasive bladder cancer

Abstract

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 Conclusions Patients diagnosed with non-muscle-invasive bladder cancer when aged
