Abstract
PURPOSE: In patients with penile cancer (PeCa) and increased risk of inguinal lymphatic dissemination, inguinal lymphadenectomy offers a direct histological staging as the most reliable tool for assessment of the nodal metastasic status and a definitive oncologic treatment simultaneously. However, peri- and/or postoperative mutilating sequalae often occurn. We report on clinical outcome and complications of a limited inguinal lymph node (LN) dissection. MATERIALS AND METHODS: Clinical and histopathological data of all patients with PeCa who underwent limited inguinal lymphadenectomy (LIL) at our institution between 1986 and 2012 were comprehensively analyzed. Perioperative results were presented in relation to one-sided procedures, if appropriate, which were assessed without cross comparison with contralateral LILs. RESULTS: 29 consecutive patients with PeCa aged 60±10.3 years were included in the current study with 57 one-sided LIL performed. Mean operative time for one-sided LIL was 89.0±37.3 minutes with 8.1±3.7 LNs removed. A complication rate of 54.4% (n=31), including 16 minor and 15 major complications was found in a total of 57 procedures with leg oedema being the most prevalent morbidity (15.8%). 4 patients with clinically positive LNs developed inguinal lymphatic recurrence within 9 months after surgery. CONCLUSIONS: Our technique of limited inguinal LN dissection provided an acceptable complication rate without aggravating morbidity. We experienced no recurrences in clinically LN negative patients, so that the approach might be a reasonable option in this scenario. In patients with enlarged LNs, radical inguinal lymphadenectomy still appears to represent the gold standard.
