Session: MP22: Bladder Cancer: Epidemiology & Evaluation I
MP22-17: The body image scale (BIS) can identify symptoms related to body image after bladder cancer treatment: Validation of the Japanese version of the BIS.
Introduction: The Body Image Scale (BIS), which consists of a 10-items, is a tool that can measure the body images of patients after cancer therapy. A multicenter cross-sectional survey was performed to validate the BIS for bladder cancer patients who received treatment in Japan. Methods: The reliability and validity of the newly developed Japanese BIS were examined in 397 Japanese patients with bladder cancer. The patients simultaneously completed the Short Form (SF)-12, and Bladder Cancer Index (BCI). Internal consistency, criterion-related validity, and correlation were evaluated. The BIS, BCI and SF-12 scores were compared according to treatment type. Results: Of 397 patients who had received bladder cancer surgery, 221 patients were treated by transurethral resection of bladder tumor (TURBT) endoscopically, 49 patients underwent cystectomy with neobladder, and 127 patients underwent cystectomy involving urinary stoma. The mean age was 70 years and a median disease duration was 29 months (IQR: 12–66 months). Cronbach's a coefficient was 0.924. Higher BIS scores indicate negative body image, and the median BIS score for patients with native bladders after TURBT (0.5) was significantly lower than those of the patients with neobladder (4.0) and stoma formation (7.0), which indicated the discriminatory ability of the BIS (p < 0.001). Correlation analysis confirmed the convergent validity. A range of BIS scores were identified among patients who reported similar SF-12 scores (Figure 1). Conclusions: The validation of BIS for diverse treatment of bladder cancer is desirable and will provide an opportunity to identify effective interventions that promote body image in clinical settings. In addition, BIS scale can detect HRQOL-specific body image deterioration that the SF-12 cannot. SOURCE OF Funding: None
