Over the past 30 years, and despite extensive clinical research, the treatment options for metastatic melanoma have been limited. Single-agent and combination chemotherapy, hormonal therapy, biochemotherapy, immunotherapy, targeted agent therapy and combination regimes have failed to show significant improvement in overall survival. Recent advances and in-depth understanding of the biology of melanoma have contributed in the development of new agents and to a change in the consideration of melanoma as one of the most therapy-resistant malignancies. Since the discovery of activating mutations in the BRAF oncogene, there has been remarkable progress in the development of targeted therapies for unresectable and metastatic melanoma, with unprecedentedly high response rates. Inactivation of immune regulatory checkpoints that limit T cell responses to melanoma has provided clinically validated targets for cancer immunotherapy, resulting in durable tumour responses. The combination of both approaches may result in additional benefits. Here we discuss current molecular targeted treatment options, immunotherapy and promising ongoing research to develop new strategies to treat melanoma.
