Several advances in diagnosis and treatment of cutaneous melanoma were discussed at the NCCN 2021 Virtual Annual Conference. First, advances in immunotherapies and targeted agents have enhanced the role of systemic therapies in the up-front management of brain metastases in melanoma while improving survival. With dual-agent immune checkpoint inhibitors, more than half of patients with asymptomatic brain metastases that are not in high-risk anatomic areas of the brain respond to treatment, and these responses appear to be durable, sparing many patients from neurosurgery and/or stereotactic radiosurgery. In addition, molecular tests increasingly have implications for clinical decision-making in later-stage disease. The most important genetic mutation in melanoma is the BRAF V600 mutation, which can be found in approximately 40% to 50% of cutaneous melanomas.
