RESUMO
For 6 patients with advanced hepatocellular carcinoma (HCC) in whom TAE was inefficacious, we tried hepatic arterial infusion chemotherapy. 5-FU 500 mg/day + CDDP 10 mg/day was administered during 5 days. The AFP level was decreased for 4 patients, and 2 patients showed a partial response in CT image. These 2 patients have been alive over 22 and 18 months, respectively. These results suggest that 5-FU + CDDP HAI might be a useful treatment of HCC inefficacious with TAE.

Three rectal cancer patients were treated with arterial infusion chemotherapy through the internal iliac artery. Two patients with pelvic recurrences unresectable after APRA were treated with intensive chemotherapy and the other patient with neoadjuvant chemotherapy. In all cases, 5-FU (500 mg/ body/day) was administered continuously for 5 days or 14 days. We attempted three methods for this procedure which were a bilateral catheterization to the internal iliac artery, a single catheterization with an embolization to the other internal iliac artery and a single catheterization without the embolization. As the result of this treatment, in the resected specimen with neoadjuvant case, histological necrosis was found in 50% in the main tumor and the metastatic lymph nodes. One patient with pelvic recurrence showed a partial response in CT imaging, but died one year later of the recurrence around the external iliac artery. The other patient with pelvic recurrence treated with the bilateral catheterization had no efficacy on CT imaging, but his CEA level has decreased at present. It was concluded that arterial infusion chemotherapy was effective for advanced rectal cancer and the pelvic recurrences. However, the efficacy of this treatment is limited to the area to which the drugs are delivered. Thus, it is important that the method and the location of the catheterization are determined adequately for each case.
