Similarly, there was no significant difference in 5-year NS between KIT WT and mutated tumours (WT NS 50.4%, 95% CI 44.7-57.3 vs. mutated NS 52.1%, 95% CI 37.1-73.2).<h4>Conclusions</h4>This is the largest national dataset on melanoma NRAS and KIT status published to date to the best of our knowledge. The gene discussed is KIT; the disease is melanoma.
