Uveal melanoma is the most common ocular malignancy for adults and despite effective therapies, roughly 50% of patients will develop metastatic disease. Currently there is no therapy to improve the prognosis of patients with metastatic disease and these patients are usually treated with regimens used for cutaneous melanoma. Tumor Treating Fields is a new type of anti-cancer therapy approved by the FDA for use in glioblastoma multiforme and mesothelioma. TTF has been shown to activate the STING pathway leading to increased levels of dendritic cells in regional lymph nodes.
Tumor Treating Fields targeted to liver metastases may improve outcomes for patients with metastatic uveal melanoma treated with immune checkpoint inhibitors.
