Abstract excerpt

OBJECTIVE: The prognosis of ampullary adenocarcinoma (AA) usually is favorable; however, a subset of AA have poor biology and outcomes similar to pancreatic cancer. Patients in this subset will have early recurrence and death usually within 2 years. To date, there are no genetic markers to identify these patients. This study identifies the high-risk subset of AA and evaluates the mutational status of KRAS in...
