Melanoma brain metastases occur in 70% of autopsies; immunotherapy combinations show superior survival versus targeted therapy, but mechanisms remain unclear. EZH2 phosphorylation recruits immunosuppressive neutrophils via G-CSF; TBK1 signaling in microglia promotes metastatic growth; metabolic reprogramming through fatty acid oxidation supports metastatic fitness.

Melanoma Brain Metastasis: Emerging Therapeutic Targets in Immune and Metabolic Pathways
Melanoma brain metastases carry poor prognosis with median survival of 6 months for 1-3 lesions and less than 2 months for leptomeningeal metastasis; immunotherapy-induced neurological adverse events affect 1-12% of treated patients.

Patients with melanoma brain metastasis may benefit from improved treatment options and survival rates; however, new therapies typically involve high out-of-pocket costs and extended treatment timelines, potentially increasing healthcare expenses for affected households.
FDA may accelerate review pathways for immunotherapy combinations targeting identified pathways (EZH2-Src, TBK1, TCTN1-CPT1A); potential for expanded insurance coverage discussions; research funding priorities may shift toward personalized oncology approaches.
