Summary

Aim: The clinical relevance of sentinel lymph node (SLN) analysis was evaluated prospectively and compared with other known risk factors of relapse in early stage melanoma. Methods: Surgery was guided by lymphoscintigraphy, blue dye and gamma probe detection. SLN were analysed by haematoxylin eosin (HE) histochemistry and multimarker immunohistochemistry (IHC). Disease free survival (DFS) was evaluated with Kaplan-Meier plots according to different parameters and Cox analyses of variance. Results: From 210 patients a total of 381 SLN were excised. Lymphoscintigraphy identified all excised SLN with only 2 false positive lymphatic lakes. Fifty patients (24%) had tumour positive SLN. With a mean follow-up of 31.3 months, 29 tumour recurrences were observed, 19 (38%) in 50 SLN positive and 10 (6%) in 160 SLN negative patients. Strong predictive factors for early relapse (p <0.0005) were SLN positivity and a high Breslow index. Conclusion: SLN tumour positivity is an independent factor of high risk for early relapse with a higher power of discrimination than the Breslow index.

Zusammenfassung

Ziel: Die klinische Bedeutung des Wächterlymphknoten(SLN)-Befalls wurde prospektiv in Bezug auf das Frühauftreten eines Rezidivs analysiert und mit anderen bekannten Risikofaktoren beim Melanom im Frühstadium verglichen. Methode: Nach der Resektion, gestützt auf Szintigraphie, Patentblau V und intraoperative Gamma- Sondenmessung, wurden die SLN mit Hämatoxylin- Eosin(HE)-Färbung und Multimarker-Immunohistochemie (ICH) untersucht. Tumorfreie überlebenszeit wurde für verschiedene Parameter nach der Kaplan-Meier-Methode und der Cox-Varianzanalyse analysiert. Ergebnisse: Bei 210 Patienten wurden 381 SLN untersucht. Die Szintigraphie identifizierte alle Lymphknoten, mit zwei falsch positiven Ergebnissen. Fünfzig Patienten (24%) wiesen einen Tumorbefall des SLN auf. Bei einer mittleren Beobachtungszeit von 31,3 Monaten wurden 29 Rezidive festgestellt, davon 19 (38%) bei 50 SLN-positiven und 10 (6%) bei 160 SLN-negativen Patienten. Den höchsten prädiktiven Wert (p <0,0005) für ein frühzeitiges Rezidiv wiesen SLN-Befall und Breslow-Index auf. Schlussfolgerung: SLN-Befall ist ein unabhängiger Risikofaktor für ein früh rezidivierendes Melanom mit besserer Diskriminanz als der Breslow- Index.
