Adherence to European Association of Urology and National Comprehensive Cancer Network Guidelines Criteria for Inguinal and Pelvic Lymph Node Dissection in Penile Cancer Patients-A Survey Assessment in German-speaking Countries on Behalf of the European Prospective Penile Cancer Study Group.

BACKGROUND

Urologists' adherence to European Association of Urology and National Comprehensive Cancer Network guideline recommendations to perform inguinal (ILND) and pelvic (PLND) lymph node dissection in penile cancer (PC) patients is not known.

OBJECTIVE

To assess a German-speaking European cohort of urologists based on their criteria to perform ILND and PLND in PC patients.

DESIGN, SETTING, AND PARTICIPANTS: A 14-item survey addressing general issues of PC treatment was developed and sent to 45 clinical centers in Germany (n = 34), Austria (n = 8), Switzerland (n = 2), and Italy (n = 1).

INTERVENTION

Two of the 14 questions assessed the criteria to perform ILND and ipsilateral PLND.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Correct responses for ILND and PLND criteria were assessed. Based on a multivariate logistic-regression-model, criteria independently predicting guideline adherence were identified.

RESULTS AND LIMITATIONS

In total, 557 urologists participated in the survey, of whom 43.5%, 19.3%, and 37.2% were residents in training, certified, and in leading positions, respectively. ILND and PLND criteria were correctly identified by 35.2% and 23.9%, respectively. Of the participants, 23.3% used external sources for survey completion. The use of auxiliary tools (odds ratio [OR] 1.57; p[] = 0.028) and participants outside of Germany (OR 0.56; p[] = 0.006) were predictors of ILND guideline adherence. The number of PC patients treated yearly (p = 0.012; OR 1.06) and the use of auxiliary tools (p < 0.001; OR 5.88) were predictors of PLND adherence. Department size, healthcare status, professional status, and responsibility for PC surgery did not predict endpoints. Limitations include sample size and results in comparison with retrospective studies.

CONCLUSIONS

Our results demonstrate overall suboptimal knowledge of the correct indications to perform ILND and PLND in PC patients among the surveyed urologists. We propose that governments and healthcare providers should be encouraged to centralize PC management.

PATIENT SUMMARY

The management of inguinal and pelvic lymph nodes is crucial for the survival of penile cancer patients. Disease rarity mandates referral to clinical practice guidelines for appropriate treatment selection.
