In resected high-risk melanoma (stage IIB/C-III) the risk of locoregional and/or distant recurrence is substantial and so far adjuvant therapies have been fairly unsuccessful. Interferon showed slight improvements in recurrence-free survival (RFS) but failed to convincingly improve overall survival (OS). In these patients, adjuvant therapy with treatments that show promising results in stage IV disease is arising. Studies using immune checkpoint blockade with anti-CTLA-4 and anti-PD-1 agents reveal convincing RFS benefits. OS rates, however, are not mature yet in most studies. Only ipilimumab has shown an OS benefit but at a high cost of toxicity. Also in studies with adjuvant targeted therapy using BRAF and MEK inhibitors, ensuring results are reported regarding RFS. As possible toxicity cannot be ignored, it is crucial to identify patients who would benefit most from these adjuvant therapies. In patients with clinically detectable lymph node metastases, studies using neoadjuvant schedules of immunotherapy and targeted therapy have been performed. In phase I and II studies the most optimal schedule of combination immunotherapy was identified and further research on this front will follow in the coming years. Concluding, after decades of scarce options for patients with high-risk melanoma, recent developments in adjuvant therapy have changed the standard of care for these patients.
