Targeted therapy for malignant ocular melanomas

Abstract

: In a comprehensive literature review, PubMed, Embasem and Web of Science were searched for studies examining targeted therapy of ocular malignant melanomas to present and discuss targeted therapy treatment options of ocular tumors, mainly conjunctival and uveal melanoma (UM). Conjunctival malignant melanomas showed similarities in clinical and genetic aspects with cutaneous melanomas. Many therapies with checkpoint inhibitors already established for cutaneous melanomas may be a treatment option for conjunctival malignant melanomas with shared traits. Existing targeted therapies are for example checkpoint inhibitors like pembrolizumab or nivolumab. As a corollary, due to marked differences in clinics and genetics between UMs and conjunctival melanomas (CMs) or cutaneous melanomas, it has remained elusive whether the available possibilities of molecular targeted therapy will be an option for the therapy of metastasizing UMs. Possible novel ways of treating UM are being explored. Fotemustine or the inoculation of dendritic cells with tumorous RNA or sunitinib in combination with cisplatin and or tamoxifen may be used in future to treat UM. While CM are treatable using targeted therapies, UM have not been researched enough to find working targeted therapy options. Further research has to be done in order to find acceptable treatment options.
