Abstract

Videoscopic inguinal lymphadenectomy (VIL) represents an innovative approach for patients with melanoma lymph node (LN) metastases, mainly aimed at lowering wound-related morbidity. However, long-term data on oncologic safety are still lacking. The aim of this study is to review the oncologic outcome of videoscopic groin dissection in a single institution caseload. Data were prospectively gathered on patients with inguinal melanoma metastasis who underwent VIL. Clinical data included age, race, sex, tumor histology, node counts and number of metastatic nodes. Disease-free survival and overall survival were monitored based on an institutional follow-up schedule. The study was approved by the local ethics committee (Video-SIIO II study). We analyzed 48 videoscopic groin dissections performed in 50 patients (2 patients underwent bilateral VIL). Median age was 54.5 years. Female/male ratio was 15/33. Indication for surgery was positive inguinal sentinel biopsy and cytological confirmed clinical disease in 40 and 10 cases, respectively. Median LN retrieval count was 19. After a median follow-up of 28 months, groin recurrence (lymphatic basin) was observed in one single case. VIL for melanoma LN metastases is associated with a favorable oncologic outcome. In particular, LN yield and locoregional recurrence rate obtained with videoscopic dissection are comparable to those reported with the open technique. Prospective studies are needed to confirm these results in a larger cohort of patients.
