BACKGROUND AND OBJECTIVES:The aim of this study was to perform a retrospective analysis of survival rates and determine prognostic indicators for patients who underwent definitive surgical resection of stage IV melanoma. METHODS:Patients included were those who underwent complete resection of metastatic melanoma. Data was analyzed using IBM SPSS 2.0. Survival estimates were derived from Kaplan-Meier, log-rank, and Breslow tests. RESULTS:The study population (n = 95) consisted of 60 males and 35 females. Median overall survival (OS) from the first metastasectomy was 49 months (95% confidence interval, 31-67 months). OS at 1, 2, and 5 years was 92%, 87%, and 50% respectively. Predictors of survival included clear surgical margins compared to patients with positive margins (median OS 53 vs 20 months, P = .026). A preoperative neutrophil to lymphocyte ratio less than 5 experienced a median OS of 65 months compared to 15 months ( P = .006; multivariable analysis for OS: hazard ratio 3.590, P = .009). CONCLUSION:This study's results are consistent with previous findings demonstrating favourable long-term outcomes following selective resection of metastatic melanoma. In addition to achieving clear surgical margins, a low preoperative neutrophil to lymphocyte ratio was associated with improved outcomes. These factors may help identify surgical candidates.
