Abstract
A recent meta-analysis showed that penile cancer (PeC) is associated with the human papilloma virus (HPV) in 50 % of patients in Europe. It is unknown whether urologists are aware of the impact of viral carcinogenesis. A (German-language) survey comprising 14 items was created and sent to urologists of 45 clinical centres in Germany (n = 34), Austria (n = 8), Switzerland (n = 2) and Italy/South Tyrol (n = 1) once in Q3/2018. According to a predefined quality standard, a total of 557 surveys were eligible for final data analysis (response rate: 85.7 %). Among other questions, urologists were asked to state the frequency of HPV-associated PeC in Europe. 4 potential answers were provided: (A)-"< 25 %", (B)-"25 - 50 %", (C)-"> 50 - 75 %", (D)-"level of association unknown". For the final calculation, a tolerance of ± 50 % was considered acceptable, so B and C were deemed correct answers. Based on a bootstrap-adjusted multivariate logistic regression model, criteria independently predicting a correct answer were identified. Categories A-D were selected in 19.2 % (n = 107), 48.8 % (n = 272), 12.9 % (n = 72) and 19 % (n = 106), respectively, representing a rate of 61.8 % of urologists (n = 344) reaching the endpoint (B + C). Autonomous performance of chemotherapy for PeC by urologists within the given centre (OR 1.55, p[Bootstrap] = 0.036) and the centre's number of urological beds (OR 1.02, p[Bootstrap] = 0.025) were the only parameters showing a significant independent impact on the endpoint. In contrast, the status of a university centre (p = 0.143), a leading position of the responding urologist (p = 0.375) and the number of PeC patients treated per year and centre (p = 0.571) did not significantly predict a correct answer. Our results demonstrate insufficient knowledge on the association of PeC and HPV among German-speaking urologists.
