Background Currently, 959 men in Germany and 67 in Austria are diagnosed with penile cancer each year, with an increase of approximately 20% in the last decade [RKI 2021, Statcube.at 2023]. Despite the rising incidence, the number of cases per hospital remains low. The median annual number of penile cancer cases at university hospitals in the DACH region was 7 patients (IQR 5-10) in 2017 [E-PROPS group 2021]. The compromised institutional expertise due to low case numbers is compounded with inadequate adherence to penile cancer guidelines, as shown in several studies. The centralization, which is rigorously implemented in countries such as the UK, enabled a significant increase in organ-preserving primary tumor surgery and stage-adapted lymphadenectomies, as well as improved patient survival in cases of penile cancer, resulting in a claim for a similar centralization in Germany and Austria. The aim of this study was to determine the current effects of case volume on penile cancer related treatment options at university hospitals in Germany and Austria.Materials and Methods In January 2023, a survey was sent to the heads of 48 urological university hospitals in Germany and Austria, including questions regarding case volume in 2021 (total number of inpatient and penile cancer cases), treatment options for primary tumors and inguinal lymphadenectomy (ILAE), the availability of a designated penile cancer surgeon, and the professional responsibility for systemic therapies in penile cancer. Correlations and differences related to case volume were statistically analyzed without adjustments.Results The response rate was 75% (n=36/48). In total, 626 penile cancer patients were treated at the 36 responding university hospitals in 2021, representing approximately 60% of the expected incidence in Germany and Austria. The annual median total number of cases was 2807 (IQR 1937-3653), and for penile cancer, it was 13 (IQR 9-26). There was no significant correlation between the total inpatient and penile cancer caseloads (p=0.34). The number of organ-preserving therapy procedures for the primary tumor, the availability of modern ILAE procedures, the presence of a designated penile cancer surgeon, and the responsibility for systemic therapies were not significantly influenced by the total inpatient or penile cancer case volume of the treating hospitals, regardless of whether the case volumes were dichotomized at the median or upper quartile. No significant differences between Germany and Austria were observed.Conclusion Despite a significant increase in the annual number of penile cancer cases at university hospitals in Germany and Austria compared to 2017, we found no case volume-related effects on structural quality with respect to penile cancer therapy. In the light of the proven benefits of centralization, we interpret this result as an argument for the necessity of establishing nationally organized penile cancer centers with even higher case volumes compared to the status quo, in light of the proven benefits of centralization.
