The prognosis of esophageal liver metastasis remains poor because of the high incidence of synchronous metastasis in other area and insufficient response to systemic chemotherapy. We assessed loco-regional anticancer potential of intra-arterial 5-FU chemotherapy for esophageal liver metastasis aimed at combination with systemic chemotherapy, radiotherapy and ablation therapy as a multidisciplinary treatment. Six patients of esophageal cancer with liver metastasis and without extra-hepatic metastasis were enrolled. Intra-aortic chemotherapy consisted of 5-FU (250 mg/body) in a one-shot infusion or a continuous infusion for 7 days with 2-week intervals until failure. The responses of liver metastasis were 2 cases of CR, 3 of PR and 1 of SD. The response rate and the local control rate were 83% and 100%, respectively. The maximum time to progression was 53 months. Grade 3/4 toxicity was not observed. Two cases had catheter failure and the treatment was interrupted. Liver metastases were controlled well until death in all cases except one. Low-dose intra-aortic 5-FU chemotherapy provided a good regional response and a combination with systemic chemotherapy may prolong survival for the patients of liver metastasis of esophageal cancer.
