title: [Evaluation of hepatic toxicity following high-dose 5-FU arterial infusion chemotherapy: analysis of 42 cases of colorectal liver metastases].
abstract: The regional toxicity of an anticancer agent for normal liver tissue following hepatic arterial infusion chemotherapy (HAI) was evaluated in terms of morphology, function, and histopathology. Forty-two patients(M:F = 30:12; mean age, 59.9 years) with liver metastases from colorectal cancer were treated with HAI using a totally implantable vascular access port system from July 1994 to March 1999. The regimen used here was so-called weekly high-dose 5-fluorouracil(5-FU) infusion(5-FU, 1,000 mg/m2/week). Volume measurement of the liver demonstrated not only whole liver atrophy including the tumor but also volume reduction of the non-tumorous lobe. Atrophic change of the liver was seen in patients who were administered over 20 g/m2 of 5-FU(p < 0.01). The CT attenuation values of the liver were examined, and fatty infiltration was seen in six patients. Histologic examination of liver biopsies from the non-tumorous part revealed steatosis and infiltration of inflammatory cells in the portal triad, which were not seen in specimens prior to HAI. On clinical laboratory findings, enzymes representing bile duct, including alkaline phosphatase, leucine amino peptidase, and gamma-glutamyltranspeptidase, were increased in 22 patients. In terms of regional toxicity for long-term HAI, 20 g/m2 of 5-FU, is the key dose at which to consider temporary cessation or dose reduction.
