Abstract
BACKGROUND Research on penile cancer (PeCa) is predominantly conducted in countries with centralized treatment of PeCa-patients. In Germany and Austria (G + A), no state-regulated centralization is established, and no information is available on how PeCa-research is organized. METHODS Current research competence in PeCa was assessed by a 36-item questionnaire sent to all chairholders of urological academic centers in G + A. Based on PubMed records, all scientific PeCa-articles of 2012-2022 from G + A were identified. Current research trends were assessed by dividing the literature search into two periods (P1: 2012-2017, P2: 2018-2022). A bibliometric analysis was supplemented. RESULTS Response rate of the questionnaire was 75%, a median of 13 (IQR: 9-26) PeCa-patients/center was observed in 2021. Retrospective case series were conducted by 38.9% of participating clinics, while involvement in randomized-controlled trials was stated in 8.3% and in basic/fundamental research in 19.4%. 77.8% declared an interest in future multicenter projects. 205 PeCa-articles were identified [median impact factor: 2.77 (IQR: 0.90-4.37)]. Compared to P1, P2 showed a significant increase in the median annual publication count (29 (IQR: 13-17) vs. 15 (IQR: 19-29), p < 0.001), in multicenter studies (79.1% vs. 63.6%, p = 0.018), and in multinational studies (53% vs. 28.9%, p < 0.001); the proportion of basic/fundamental research articles significantly declined (16.5% vs. 28.9%, p = 0.041). Four of the top-5 institutions publishing PeCa-articles are academic centers. Bibliometric analyses revealed author networks, primary research areas in PeCa, and dominant journals for publications. CONCLUSIONS Given the lack of centralization in G + A, this analysis highlights the need for research coordination within multicenter PeCa-projects. The decline in basic/fundamental research should be effectively addressed by the allocation of funded research projects.

Abstract
PURPOSE To assess the long-term risks of infectious and thromboembolic events following inguinal (ILND) and pelvic (PLND) lymph node dissection in men with penile cancer. MATERIAL AND METHODS A total of 364 men subjected to ILND with or without PLND for penile cancer between 2000 and 2012 were identified in the Swedish National Penile Cancer Register. Each patient was matched based on age and county of residence with six penile cancer-free men. The Swedish Cancer Register and other population-based registers were used to retrieve information on treatment and hospitalisation for selected infectious and thromboembolic events. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated using Cox proportional hazard models with multiple imputation. RESULTS The risk of infectious events remained increased for more than five years postoperatively in men with penile cancer compared with matched controls. The palpable nodal disease was the only predictor of these events, with risk increasing with the cN stage. The HR at one, three and five years and six months postoperatively was 8.60 (95% CI 5.16-14.34), 4.02 (95% CI 2.65-6.09) and 1.93 (95% CI 1.11-3.38), respectively. An increased risk of thromboembolic events persisted for three years postoperatively. The HR at one and three years postoperatively was 13.51 (95% CI 6.53-27.93) and 2.12 (95% CI 1.07-4.20). The results correspond well with the over-prescription of anticoagulants observed during this period. An association with bulky disease (cN3) was observed. CONCLUSIONS Lymph node dissection for penile cancer is associated with an increased risk of infectious and thromboembolic events. The findings of this population-based study show that the risks of these events remain increased more than five years for infectious and three years for thromboembolic events. Improved awareness of long-term complications following ILND is of importance both among patients and care givers to ensure early detection and treatment.
