The study found that most German-speaking urologists have insufficient knowledge on the association between penile cancer (PeC) and human papilloma virus (HPV). Factors such as autonomous chemotherapy performance for PeC and the number of urological beds in a center had a significant impact on the urologists' understanding of HPV-associated PeC, while other factors like university status or number of PeC patients treated per year did not show significant predictive value.
Background 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. Methods 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. Results 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. Conclusions Our results demonstrate insufficient knowledge on the association of PeC and HPV among German-speaking urologists.
