A 62-year-old man with a history of anorexia and weight loss over the past 3 months presents with obstructive painless jaundice that has been present for the past 24 hours. In the emergency department, an abdominal multi-detector computed tomography (MDCT) scan identifies dilated common and intrahepatic bile ducts due to a 4.6 × 3.7 cm mass in the head of the pancreas and multifocal liver lesions, the largest of which is 2.7 cm in diameter. A biliary stent is placed via endoscopic retrograde cholangiopancreatography (ERCP), and forceps biopsy provides tissue confirmation of pancreatic adenocarcinoma. Findings from ultrasound-guided core biopsy of 1 of the liver lesions are consistent with metastatic pancreatic adenocarcinoma. The patient otherwise has excellent performance status with no medical comorbidities and desires treatment with the goals of prolonging his life and maintaining his quality of life. You are consulted for an opinion regarding the best possible treatment option.
