Background: Several new medications have shown improved survival rates in high-risk patients with melanoma.
Objective: The aim of this article is to discuss the new medications and outline their roles, the expected benefit from each and the risk of adverse events. We explain the place of sentinel lymph node biopsy (SLNB) and ultrasonography with fine needle aspiration (US-FNA) in assessing and treating patients with melanoma.
Discussion: Ipilimumab has limited efficacy and a very concerning complication profile. More than 50% of patients taking ipilimumab have severe or life-threatening adverse events. BRAF inhibitors have greater efficacy and fewer adverse events than ipilimumab. Combining BRAF inhibitors with mitogen-activated protein kinase inhibitors enhances their effect and improves the overall adverse event profile. BRAF inhibitors are only effective when the melanoma has a BRAF gene mutation, something that occurs in only 50% of cases. Programmed cell death protein 1 medications are also more effective and have a much more acceptable adverse event profile than ipilimumab. Both SLNB and US-FNA can detect early node involvement in patients with melanoma, although US-FNA is a safer procedure.
