Supplementary Material for: Acceptance of Adjuvant and Neoadjuvant Chemotherapy in Muscle-Invasive Bladder Cancer in Germany: A Survey of Current Practice

<b><i>Background:</i></b> Guidelines support the use of neoadjuvant (NAC) and adjuvant (AC) chemotherapy in muscle-invasive bladder cancer. However, data from North America reported the underutilization of NAC in favor of AC despite the lower level of scientific evidence supporting AC. We aimed to assess current practice patterns of NAC and AC in ­Germany. <b><i>Methods:</i></b> A 15-question online survey was developed and sent via email newsletters to members of the ­German Association of Urology and of the German Society of Residents in Urology in October 2016 to analyze current practice patterns. <b><i>Results:</i></b> The survey yielded 141 individual responses from 61 different German urology departments. Eighty-nine (69.0%) and 119 (93.0%) participants were stated to regularly use NAC and AC respectively. The number of participants who were stated to use NAC and AC regularly was not associated with the type of institution (academic vs. nonacademic), number of hospital beds, and number of cystectomies performed annually. Gemcitabine/cisplatin combination chemotherapy was named as the primarily used NAC regimen by 80 (95%) respondents. The median number of administered cycles was 3 for NAC and 4 for AC. In the case of cisplatin ineligibility, combination chemotherapy with gemcitabine/carboplatin was the most common regimen. Respondents stated that chemotherapy was generally administered by urologists (81% for NAC and 85% for AC). <b><i>Conclusions:</i></b> Our survey of current practice shows a high acceptance rate of NAC in Germany, which was independent of the type of institution. Although the scientific level of evidence for AC is lower, it still seems to be more widely accepted than NAC. NAC and AC were generally administered by urologists
