Optimising prediction of early metastasis-free survival in uveal melanoma using a four-category model incorporating gene expression profile and tumour size.

Background: Largest basal diameter (LBD) appears to have independent prognostic value in uveal melanoma (UM).

Methods: All patients undergoing plaque brachytherapy or enucleation for UM involving the choroid and/or ciliary body between 2012 and 2019.

Results: A total of 348 patients with a mean age of 60±14 years were included and followed for a mean of 40±26 months (3.
