NRAS-mutant Melanoma : Characteristics

Jakob et al. Cancer 2012

•NRAS mutated in 10-15% melanomas •Majority of congenital melanocytic nevi •Meta-analysis: 31 studies and 1972 patients no association Age-NRAS no association Gender-NRAS •NRAS mutations associated:

thicker primary increased mitotoc rate lower incidence of ulceration •Linked to poorer survival compared to BRAF and WT melanomas

Future

• Identification and validation of new targets or new ways to optimally act on already known targets

• Predictive biomarker identification and increased ability to evaluate the correlates with survival benefit

• Greater knowledge of the effect of combination therapy
