[Study of intraarteric infusion chemotherapy with drug delivery system]

We have studied the effect of intraarteric infusion chemotherapy with missile chemotherapy, induced hypertensive chemotherapy and/or two-route infusion chemotherapy in 14 liver tumors (7 cases with liver metastasis from gastric cancer, 3 cases with liver metastasis from colonic cancer, 4 cases with hepatoma). Results indicated that PR in 6 (46.1%) out the 13 evaluated cases. The toxicity was not evident except for slight bone marrow depression with 5 cases and a low grade fever with 2 cases. These results indicate that intraarterial infusion chemotherapy with drug delivery system can be considered one of the treatment therapies available for a nonresectable tumor.
