[Complication due to arterial infusion chemotherapy for liver metastasis from colorectal cancer].
OBJECTIVE
Arterial infusion chemotherapy is considered to be an extremely effective treatment for liver metastasis from colorectal cancer in terms of its tumor reduction and preventing recurrence in residual liver after resection. However, there still remain some unclear points as to the influence on hepatic artery and bile duct when this treatment is used over the long term. We report some conclusions obtained by examining cases of hepatic arterial occlusion (stenosis) and biliary complication who received this treatment.


METHODS
Thirty-six cases who received this treatment over 3 months were the objects of this study, with the aim of direct effect against metastatic focus (21 cases) and prevention of recurrence in residual liver (15 cases). The ages were from 27 to 81; 22 cases were male and 14 were female. Indwelling routes of catheter were gastroduodenal artery (GDA) in 28 cases and femoral artery (FA) in 8 cases. Intermittent high-dose infusion (WHF: 5-FU 1,000 mg/m2/5 hrs qw) was adopted as the method.


RESULTS
Hepatic arterial occlusion or stenosis was observed in 12 cases (GDA: 10; FA: 2). There seemed to be no correlation with the total dosage of 5-FU or the number of administrations. Even when hepatic arterial occlusion or stenosis occurred, no change was observed in liver function, and there no death was caused by this. However, CT showed a low-density area followed by atrophy in the right lobe in one case with right hepatic arterial stenosis, despite normal portal blood flow. Of the 6 cases which developed obstructive jaundice, 4 were due to the increase of metastatic focus or lymph nodes, and 1 case without dilatation of bile duct died from suspected sclerosing cholangitis. In this case, ALP had been increasing since 1 month before the onset of jaundice. Another case which developed biloma accompanied by the increase of serum bilirubin improved by discontinuance of chemotherapy.


CONCLUSIONS
Since arterial infusion chemotherapy for liver metastasis from colorectal cancer causes hepatic arterial occlusion (stenosis) at a high rate, early detection of abnormalities by liver function test and imaging diagnosis which leads to early treatment is important.
