To address such needs, the European Organization for Research and Treatment of Cancer (EORTC) QOL group developed modules for BC in the 1990s, and Blazeby et al. [8] validated a module specific for NMIBC, EORTC QLQ-NMIBC24 questionnaire in 2014. This questionnaire is a selfadministered, multidimensional instrument exploring QOL of NMIBC patients in six scales (urinary symptom, malaise, future worries, bloating and flatulence, sexual function, and male sexual problems) and five single items (intravesical treatment issues, sexual intimacy, risk of contaminating a partner, sexual enjoyment, and female sexual problems). However, its applicability in different countries except an original European study [8] has not been reported. In this study, we developed a Korean version of QLQ-NMIBC24 questionnaire, and evaluated its psychometric properties to determine if it is appropriate for evaluating the outcomes of Korean NMIBC patients.
