treatment for a patient with metastatic or unresectable disease, key factors include BRAF mutation status, tumor bulk, and tempo. An important consideration is whether the patient “has time for an immune response to develop,” he noted. Using Ipilimumab

mutations have been found in this population ( Table 1 ). Typically, in those with RDD, BRAF mutations do not occur; however, MAPK pathway gene mutations are common. “Notably, [in] approximately 10% to 20% of cases, the mutations remain unknown,” Dr. Go
