Impact of bladder cancer on health-related quality of life.
OBJECTIVES:To identify changes in health-related quality of life (HRQoL) after diagnosis of bladder cancer in older adults in comparison with a group of adults without bladder cancer (controls). PATIENTS AND METHODS:Data from the Surveillance, Epidemiology and End Results registries were linked with Medicare Health Outcomes Survey (MHOS) data. Medicare beneficiaries aged ≥65 years in the period 1998-2013, who were diagnosed with bladder cancer between baseline and follow-up through the MHOS, were matched with control subjects without cancer using propensity scores. Linear mixed models were used to estimate predictors of HRQoL changes. RESULTS:After matching, 535 patients with bladder cancer (458 non-muscle-invasive bladder cancer [NMIBC] and 77 with muscle-invasive bladder cancer [MIBC]) and 2 770 control subjects without cancer were identified. Both patients with NMIBC and those with MIBC reported significant declines in HRQoL scores over time vs controls: physical component summary -2 and -5.3 vs -0.4, respectively; bodily pain -1.9 and -3.6 vs -0.7; role physical -2.7 and -4.7 vs -0.7; general health -2.4 and -6.1 vs 0; vitality -1.2 and -3.5 vs -0.1; and social functioning -2.1 and -5.7 vs -0.8. All scores ranged from 0 to 100. When stratified by time since diagnosis, HRQoL improved over 1 year for some domains (role physical), but remained lower across most domains. CONCLUSIONS:After diagnosis, patients with bladder cancer experienced significant declines in physical, mental and social HRQoL relative to controls. Decrements were most pronounced among individuals with MIBC. Methods to better understand and address HRQoL decrements among patients with bladder cancer are needed.
