Description
In a case report, a patient with pancreatic cancer harboring BRAF N486-P490del was treated with trametinib. Within 4 weeks of initiating therapy, her serum CA19-9 had fallen from 36,000 to 8,100 U/mL, and the radiographic partial response was revealed by CT at 8 weeks after initiation of trametinib. cfDNA measurements for BRAF and TP53 alleles revealed a dramatic decline in response to trametinib. After 6 months of therapy, radiographic progression was identified.
