Looking into a Better Future: Novel Therapies for Metastatic Melanoma.

Even though melanoma represents a small percentage of all cutaneous cancers, it is responsible for most deaths from skin neoplasms. In early stages it can be successfully treated with surgery, but as the disease expands the survival rate drops significantly. For many years the mainstay of treatment for metastatic melanoma was chemotherapeutic agents, even though they failed to prove survival prolongation. After the advent of ipilimumab, a survival benefit and better overall response rate could be offered to the patients. Other new therapies, such as immunotherapies, targeted therapies, vaccines, and small molecules, are currently being studied. Also, combination regimens have demonstrated superiority to some monotherapies. Nowadays, ipilimumab should no longer be considered the first-line therapy given its severe toxicity and lower efficacy, while nivolumab remains efficacious and has a good safety profile. T-VEC as monotherapy has been shown to be an elegant alternative even for the elderly or cases of head and neck melanomas. If the BRAF mutation status is positive, the combination of dabrafenib and trametinib could be an option to consider. Despite the success of the novel treatments, their effectiveness is still limited. New studies have opened up new avenues for future research in melanoma treatment, which is expected to lead to better therapeutic outcomes for our patients. The objective of this review is to discuss the novel therapies for metastatic melanoma that have been tested in humans during the last 3 years to obtain a sharper perspective of the available treatment options for specific patient characteristics.
