Purpose of the study: The usefulness of sentinel lymph node biopsy in thick melanomas is debated. The aim of this study was to evaluate the possible prognostic significance of sentinel lymph node biopsy in T4 melanoma patients and to verify whether this was a homogeneous group of patients with similar poor behavior. Materials and Methods: A retrospective observational study was performed. Data were extracted from the Tuscan Regional Referral Center database. The outcome of sentinel lymph node-negative and sentinel lymph node-positive T4 melanomas were compared. A systematic review of published series on this issue and a meta-analysis were performed. Results: Among 125 T4 melanoma patients, 53 patients (42.4%) were sentinel lymph node-positive and 72 (57.6%) patients were sentinel lymph node-negative. The 5-year and the 10-year melanoma specific survival were 81.9% and 72.3% for sentinel lymph node-negative patients and 42.4% and 17.9% (P < 0.001) for sentinel lymph node-positive patients. A positive sentinel lymph node showed an HR of 3.08. The meta-analysis confirmed that there was a significantly greater risk of death for patients with thick melanoma and positive sentinel lymph node (RR 1.75). Conclusions: The results of the study point out that the sentinel lymph node biopsy is required for the correct staging of patients with melanoma thicker than 4 mm and that the status of sentinel lymph node is a significant predictor of melanoma specific survival. This knowledge allows early surgical and adjuvant treatment as well as appropriate trial enrollment and tailored follow-up. [ABSTRACT FROM AUTHOR] |
