          Abstract

          Pseudoaneurysms of the hepatic artery are a rare complication in patients with primary or secondary liver tumors treated with intra-arterial chemotherapy. We present two patients who developed this complication after placement of a catheter system into the gastroduodenal artery and initiation of regional chemotherapy with floxuridine. Diagnosis was made after symptomatic bleeding occurred, necessitating emergency angiography with coil embolization. Pseudoaneurysms usually occur after mechanical damage of the vessel wall, but the chemical toxicity of floxuridine may add to the development of vascular impairment.

          Hepatic arterial infusion of chemotherapy after resection of hepatic metastases from colorectal cancer.

          Two years after undergoing resection of liver metastases from colorectal cancer, about 65 percent of patients are alive and 25 percent are free of detectable disease. We tried to improve these outcomes by treating patients with hepatic arterial infusion of floxuridine plus systemic fluorouracil after liver resection. We randomly assigned 156 patients at the time of resection of hepatic metastases from colorectal cancer to receive six cycles of hepatic arterial infusion with floxuridine and dexamethasone plus intravenous fluorouracil, with or without leucovorin, or six weeks of similar systemic therapy alone. Patients were stratified according to previous treatment and the number of liver metastases identified at operation. The study end points were overall survival, survival without recurrence of hepatic metastases, and survival without any metastases at two years. The actuarial rate of overall survival at two years was 86 percent in the group treated with local plus systemic chemotherapy and 72 percent in the group given systemic therapy alone (P=0.03). The median survival was 72.2 months in the combined-therapy group and 59.3 months in the monotherapy group, with a median follow-up of 62.7 months. After two years, the rates of survival free of hepatic recurrence were 90 percent in the monotherapy group and 60 percent in the monotherapy group (P<0.001), and the respective rates of progression-free survival were 57 percent and 42 percent (P=0.07). At two years, the risk ratio for death was 2.34 among patients treated with systemic therapy alone, as compared with patients who received combined therapy (95 percent confidence interval, 1.10 to 4.98; P=0.027), after adjustment for important variables. The rates of adverse effects of at least moderate severity were similar in the two groups, except for a higher frequency of diarrhea and hepatic effects in the combined-therapy group. For patients who undergo resection of liver metastases from colorectal cancer, postoperative treatment with a combination of hepatic arterial infusion of floxuridine and intravenous fluorouracil improves the outcome at two years.

            Hepatic arterial infusion versus systemic therapy for hepatic metastases from colorectal cancer: a randomized trial of efficacy, quality of life, and molecular markers (CALGB 9481).

            Hepatic metastases derive most of their blood supply from the hepatic artery; therefore, for patients with hepatic metastases from colorectal cancer, hepatic arterial infusion (HAI) of chemotherapy may improve outcome. In a multi-institutional trial, 135 patients were randomly assigned to receive HAI versus systemic bolus fluorouracil and leucovorin. The primary end point was survival; secondary end points were response, recurrence, toxicity, quality of life, cost, and the influence of molecular markers. Overall survival was significantly longer for HAI versus systemic treatment (median, 24.4 v 20 months; P = .0034), as were response rates (47% and 24%; P = .012) and time to hepatic progression (THP; 9.8 v 7.3 months; P = .034). Time to extrahepatic progression (7.7 v 14.8 months; P = .029) was significantly shorter in the HAI group. Quality-of-life measurements showed improved physical functioning in the HAI group at the 3- and 6-month follow-up assessments. Toxicity included grade > or = 3 neutropenia (2% and 45%; P or = 4, the median survival was 24 and 14 months, respectively (P = .17). HAI therapy increased overall survival, response rate, THP, and was associated with better physical functioning compared with systemic therapy. Additional studies need to address the overall benefit and cost of new chemotherapy agents versus HAI alone or the combination of HAI with new agents.
