Introduction Patients with Stage IV melanoma have limited therapeutic options with few long-term survivors. Our goal was to study the impact of metastasectomy on survival in these patients. Methods Patients with Stage IV melanoma were identified from the Surveillance, Epidemiology, and End Results (SEER) database (1988-2006). Those who had metastasectomy performed were compared with patients that did not. Results The median age of the study population (n = 4,229) was 63 years and median survival was 7 months. Patients who underwent metastasectomy (33.6%) had an improved median and 5-year overall survival as compared to patients who did not; 12 months versus 5 months and 16% versus 7% (P < 0.001). In patients with M1a disease (n = 1,994), this improvement of survival following metastasectomy was enhanced; median survival of 14 months versus 6 months and 5-year overall survival of 20% versus 9% (P < 0.001). Younger age and diagnosis from 2001 to 2006 were predictors of metastasectomy. Metastasectomy was an independent and significant predictor of survival for the entire cohort (HR 0.59, 95% CI 0.55-0.63). Conclusions Metastasectomy in patients with Stage IV melanoma may improve long-term survival. The true therapeutic benefit, if any, of metastatectomy needs to be determined by a randomized trial. J.
