Nonmuscle Invasive Bladder Cancer Influences Physical Health Related Quality of Life and Urinary Incontinence

Abstract Objective To evaluate the effects of nonmuscle invasive bladder cancer (NMIBC) on health-related quality of life (HRQOL) and urinary function within patients diagnosed with NMIBC as compared to the general population. Methods Using the Surveillance, Epidemiology, and End Results-Medicare Health Outcome Survey (SEER-MHOS) database (1998-2013), 325 patients diagnosed with NMIBC with baseline and postdiagnosis MHOS surveys were propensity-matched 1:5 to noncancer controls (NCC). Multivariate linear regression analysis compared NMIBC patients with matched NCC in terms of physical component summary (PCS), mental component summary (MCS), and health domain scales. Changes in urinary function were assessed using χ 2 testing. Results Patients diagnosed with NMIBC experienced significant decline in PCS vs NCC (−3.0, 95% confidence interval [CI –4.1, –2.0] vs −1.5, 95%CI [−2.0, −1.0], P  = .01), while the observed decline in MCS was not significantly different ( P  = .09) between groups. On sub-analysis, the significant decline in PCS was confined to patients with high-risk NMIBC ( P  = .01). NMIBC patients had significantly greater decline in role physical ( P  = .04), general health ( P  = .04) and role emotional ( P P values all Conclusion NMIBC diagnosis was associated with significant decreases in physical HRQOL and urinary function compared with NCC. Further study focused on NMIBC patients, and the inherent HRQOL factors to this diagnosis is needed to assess where improvements can be made in treating this patient population.
