New molecular prognostic classification for uveal melanoma based on the data generated by the TCGA project involving primary uveal melanoma cases [40]. The new model comprises four main prognostic classes: class A [D3/D8], class B (D3/partial extra 8q), class C (M3/8q gain) and class D (M3/multiple 8q gains). The risk of metastases development increases progressively from class A to class D. Uveal melanoma patients in class D have the least favourable prognosis, with nearly all patients dying within the first decade after diagnosis.
