[A new method of short-term high volume (6 g of 5-FU in a week) intermittent hepatic arterial infusion using repeated transient catheter insertion].

We report a case of liver metastases, which had hepatectomy twice and a partial lung resection after sigmoidectomy with partial bladder resection for advanced sigmoid colon cancer. The patient could not be tolerated the systemic chemotherapy, and percutaneous implantation of a catheter also could not have done with subcutaneous reservoir for hepatic arterial infusion because of an anomaly of hepatic artery branched-out from super mesenteric artery. Therefore, we tried an intermittent hepatic arterial infusion using a transient insertion of catheter to control the liver metastases' growth. A total amount of 6 g of 5-FU was continuously injected in a week by one insertion of catheter at the hepatic artery taking one day rest at day 4. During the next 21 months, a total of 11 courses have been done. CEA and CA19-9 were changed from 15 ng/mL, 48 U/ mL to 18, 30, respectively. The patient was able to keep working except for the duration of this treatment. This procedure could be one of the hepatic arterial infusion options.
