Gastric ulceration as a complication of hepatic artery infusion chemotherapy

Based upon the cases reported in this paper and upon a literature review encompassing 1,783 patients having received HAIC, it is our opinion that upper gastrointestinal tract ulceration is a potentially significant complication of hepatic artery infusion chemotherapy. In addition, we believe that the mechanism responsible for HAIC-induced ulceration often involves direct perfusion of the gastric arterial supply with chemotherapeutic agents. The occurrence of ulcerations in patients with surgically placed catheters is disconcerting, and does not allow for any apparent easy method of alleviating HAIC-induced ulceration. Clinicians should be alerted to the possibility of gastric and duodenal ulceration in patients treated with HAIC, and should afford particular attention to gastrointestinal symptoms during hepatic artery infusion chemotherapy.
