Varying Mutational Alterations in Multiple Primary Melanomas

In melanoma, the mitogen-activated protein (MAP) kinase pathway plays a crucial oncogenic role. Recent studies identified additional genetic alterations, eg, TERT-promoter mutations. Up to 8% of melanoma patients present with multiple primary melanomas (MPMs). The pathogenesis is not fully understood, and data on the genetic diversity of MPMs are limited. To identify putative diagnostic and therapeutic consequences, we assessed the mutational status of the BRAF and NRAS genes and TERT promoter in patients with MPMs.
