: Despite observing progress in recent years in the treatment of patients with advanced melanoma, the optimal management of locoregional recurrence has not been determined. Various methods are used to treat this group of patients. One of these methods is electrochemotherapy. The present study presents the distant results in treating patients with the locoregional recurrence of melanoma, using the technique of electrochemotherapy. This study includes a retrospective analysis of 88 patients' data with locoregional melanoma recurrence, treated with electrochemotherapy (ECT) between 2010 and 2023, in two reference centers. Approximately 80% of patients responded to the ECT treatment, achieving partial or complete remission. In a multivariate analysis, statistically significant longer overall survival was found in the group of patients who achieved complete remission after ECT and were treated with immunotherapy. The results may suggest the existence of synergy between ECT and immunotherapy. However, confirmation of this fact requires further prospective studies that will also establish the role of ECT in the combination treatment of patients with locoregional recurrence of melanoma.
