[Evaluation of long survival cases treated with intra-arterial cancer chemotherapy using implantable reservoirs].

We have treated unresectable liver tumor with intraarterial infusion chemotherapy using an implantable reservoir since 1983. Out of the total 44 cases receiving the chemotherapy during the period from 1983 to February 1989, the evaluation of 8 cases (18.2%) surviving over a year is reported. The 8 cases consist of 3 cases of primary hepatic cancer, 4 cases of metastatic hepatic cancer and 1 case of malignant hemangiopericytoma of pelvis. The cases of primary hepatic cancer are 2 cases of hepatoma (413, 420 days) and 1 case of cancer of bile-duct (400 days). The metastatic cases are 1 case of gastric cancer (826 days), 2 cases of colo-rectal cancer (698, 1080 days) and 1 cases of leiomyosarcoma of small intestine (577 days). A case of malignant hemangiopericytoma of pelvis has survived 4 years and 3 months after the infusion chemotherapy via the internal iliac artery. The two cases of colo-rectal cancer were treated with continuous infusion of FUDR via the proper hepatic artery using Infusaid. For the other cases, ADM and CDDP were infused repeatedly with single-shot type Infuse-a port. Intra-arterial infusion chemotherapy is very useful because treatment in the outpatient clinics is possible over the longterm, and it is possible for patients receiving the therapy to maintain quality of life.
