S15 Ep13: Hepatic Artery Infusion Refines Liver-Directed Care for GI Cancers: With Gregory J. Tiesi, MD, FACS, FSSO; Anthony Scholer, MD, FACS, FSSO; Benjamin Jon Golas, MD, FACS; and Eric Pletcher, MD

In this episode, Gregory J. Tiesi, MD, FACS, FSSO, hosted a discussion about the use of hepatic artery infusion (HAI) in colon cancer and liver cancer management. Dr Tiesi is the medical director of Hepatobiliary Surgery at the Hackensack Meridian Jersey Shore University Medical Center in Neptune, New Jersey. He was joined by: Anthony Scholer, MD, FACS, FSSO, a surgical oncologist specializing in hepatobiliary surgery, at Hackensack Meridian Medical Group and Jersey Shore University Medical Center in Neptune, New Jersey Benjamin Jon Golas, MD, FACS, regional chief of Surgical Oncology for Hackensack Meridian Health’s Central Region, surgical director of Oncology Services at Jersey Shore University Medical Center, vice chair of Surgery at Jersey Shore University Medical Center Cancer Surgery, and an associate professor of surgery at the Hackensack Meridian School of Medicine in Nutley, New Jersey Eric Pletcher, MD, a surgeon specializing in Complex General Surgical Oncology at Hackensack Meridian JFK University Medical Center in Edison Drs Tiesi, Scholer, Golas, and Pletcher explained that HAI is a longstanding regional therapy used for treating primary and metastatic tumors to the liver, notably unresectable colorectal liver metastases and intrahepatic cholangiocarcinoma. The physiologic mechanism of this treatment leverages the dual blood supply of the liver, capitalizing on the fact that these malignancies primarily derive their perfusion from the hepatic artery, the experts noted. They emphasized that by delivering chemotherapeutic agents, such as floxuridine, directly via the gastroduodenal artery, HAI concentrates drug exposure at the tumor site, maximizing antitumor effect and minimizing extrahepatic toxicity. They explained that patient selection requires fitness for surgery and good liver function, excluding those with cirrhosis or portal hypertension. They also noted that the procedure involves implanting a subcutaneous pump, followed by rigorous intraoperative and postoperative nuclear medicine studies to confirm the absence of extrahepatic perfusion. Evidence supports that HAI combined with systemic therapy achieves higher intrahepatic objective responses, improves local disease control, and enhances conversion to resectability, correlating with improved long-term survival, the experts reported. However, potential complications include pump pocket infections, biliary sclerosis, and gastric ulcers, they added. The experts concluded by highlighting that establishing an HAI program necessitates a robust, multidisciplinary approach involving surgical oncology, medical oncology, and interventional radiology.
