Discrepancy Between European Association of Urology Guidelines and Daily Practice in the Management of Non–muscle-invasive Bladder Cancer: Results of a European Survey

Abstract

BackgroundThe European Association of Urology (EAU) non–muscle-invasive bladder cancer (NMIBC) guidelines are meant to help minimise morbidity and improve the care of patients with NMIBC. However, there may be underuse of guideline-recommended care in this potentially curable cohort. ObjectiveTo assess European physicians’ current practice in the management of NMIBC and evaluate its concordance with the EAU 2013 guidelines. Design, setting, and participantsInitial 45-min telephone interviews were conducted with 20 urologists to develop a 26-item questionnaire for a 30-min online quantitative interview. A total of 498 physicians with predefined experience in treatment of NMIBC patients, from nine European countries, completed the online interviews. Outcome measurements and statistical analysisDescriptive statistics of absolute numbers and percentages of the use of diagnostic tools, risk group stratification, treatment options chosen, and follow-up regimens were used. Results and limitationsGuidelines are used by ≥87% of physicians, with the EAU guidelines being the most used ones (71–100%). Cystoscopy (60–97%) and ultrasonography (42–95%) are the most used diagnostic techniques. Using EAU risk classification, 40–69% and 88–100% of physicians correctly identify all the prognostic factors for low- and high-risk tumours, respectively. Re-transurethral resection of the bladder tumour (re-TURB) is performed in 25–75% of low-risk and 55–98% of high-risk patients. Between 21% and 88% of patients received a single instillation of chemotherapy within 24h after TURB. Adjuvant intravesical treatment is not given to 6–62%, 2–33%, and 1–20% of the patients with low-, intermediate-, and high-risk NMIBC, respectively. Patients with low-risk NMIBC are likely to be overmonitored and those with high-risk NMIBC undermonitored. Our study is limited by the possible recall bias of the selected physicians. ConclusionsAlthough most European physicians claim to apply the EAU guidelines, adherence to them is low in daily practice. Patient summaryOur survey among European physicians investigated discrepancies between guidelines and daily practice in the management of non–muscle-invasive bladder cancer (NMIBC). We conclude that the use of the recommended diagnostic tools, risk-stratification of NMIBC, and performance of re-TURB have been adopted, but adjuvant intravesical treatment and follow-up are not uniformly applied.
