Abstract

Background

In order to define patients eligible for only a superficial groin dissection or a combined superficial and deep groin dissection, this study aimed to determine the incidence of deep lymph node metastases (LNM) in patients with melanoma metastasized to the groin, to identify patient and melanoma factors that predict deep nodal involvement, and to analyze the impact of deep nodal involvement on survival and recurrence.

Methods

Patients who underwent a combined superficial (inguinal) and deep (iliac and obturator) complete (CLND) or therapeutic lymph node dissection (TLND) of the groin between 1994 and 2012 were analyzed.

Results

QueryDeep LNM were found in 8 of 62 CLND patients (13 %) and in 21 of 67 TLND patients (31 %). More than three superficial LNM was the only independent predictor for deep LNM in both CLND and TLND patients. The 5-year melanoma-specific survival (MSS) for CLND and TLND patients with deep LNM was 14.3 and 16.6 %, respectively, and was significantly worse (hazard ratio [HR] 3.39, 95 % CI 1.34–8.58, p = 0.010; and HR 2.01, 95 % CI 1.04–3.88, p = 0.039) compared with CLND and TLND patients without deep LNM (5-year MSS: 54.1 and 37.2 %, respectively). Distant recurrence was significantly associated with deep LNM in CLND patients (p = 0.032).

Conclusions

The present study showed that LNM in the deep area of the groin are fairly common in both CLND and TLND patients and significantly affect prognosis, especially in CLND patients. The number of superficial LNM is the only factor that was found to predict a finding of deep nodal metastases.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
