Pancreas Cancer With Hepatic Metastase

The goal of this observational study is to evaluate whether hepatic artery infusion pump (HAIP) chemotherapy can improve outcomes in patients with pancreatic or duodenal adenocarcinoma who have isolated or liver-dominant metastases after surgery and systemic chemotherapy. The main questions it aims to answer are: Does HAIP chemotherapy improve liver tumor response based on imaging criteria (RECIST)? What are the progression-free survival and overall survival outcomes in this patient population? Participants will: Undergo placement of a hepatic artery infusion pump as part of standard clinical care Receive floxuridine (FUDR)-based chemotherapy through the pump Have clinical data, imaging results, and laboratory markers (e.g., ctDNA, CEA, CA 19-9) collected from their medical records over time
