ABSTRACT

OBJECTIVE: Dynamic sentinel node biopsy (DSNB) has been recommended in the EAU guidelines for several years as a minimally invasive method for lymph node staging in patients with penile carcinoma and nonpalpable lymph nodes. However, due to the high methodological demands and the primarily unreliable results, this method is rarely used in Germany. The aim of this study was to establish the reliability and morbidity of this method. MATERIAL AND METHODS: The frequency of lymph node recurrent disease and complications were prospectively recorded in patients with initially nonpalpable inguinal lymph nodes and histologically negative sentinel lymph nodes. Quality criteria were the false negative rate (percentage of lymph node recurrence in negative procedures) and the morbidity rate. Inguinal regions with palpable lymph nodes and/or evidence of metastases were not considered. RESULTS: The study included 37 patients with histologically negative sentinel lymph nodes in 63 groins with nonpalpable inguinal lymph nodes. There were 21 T1(a/b) stages, 10 T2, and 6 T3 stages. Tumor differentiation was good in 4, moderate in 26, and poor in 7 patients. During a median follow-up of 52 months (range 1-131 months), we observed a bilateral lymph node recurrence in 1 patient and a conservatively managed prolonged lymphorrhea in another patient. Per inguinal region the false-negative rate was 3.2 % and the morbidity rate was 1.6 %; seen per patient the rates were both 2.7 %. CONCLUSIONS: DSNB is a reliable method of lymph node staging in patients with penile carcinoma and nonpalpable inguinal lymph nodes. The high degree of reliability in combination with the low morbidity justifies the higher methodical complexity of this method.
