Management of patients with unresectable liver metastases from colorectal and gastric cancer employing an implantable port system.
Between 1985 and 1990, 50 patients with unresectable liver metastases from colorectal cancer and 34 subjects with metastases from gastric cancer were treated by repeated hepatic arterial infusion chemotherapy employing an implantable prot system. A catheter was inserted into the hepatic artery via the left subclavian artery and was connected to the implantable injection port in each patient. 5-Fluorouracil (5-FU) at 330 mg/m2 per week (167 mg/m2 daily given continuously over the initial 3 months for colorectal cancer), Adriamycin (ADR) at 20 mg/m2 every 4 weeks and mitomycin C (MMC) at 2.7 mg/m2 every 2 weeks were given to all 34 patients with gastric cancer and to 31 of the colorectal cancer patients. The remaining 19 patients with colorectal cancer received 5-FU at 1,000 mg/m2 every week. As a rule the treatment was performed on an outpatient basis. The side effects and complications observed included myelosuppression (23%), hepatic arterial occlusion (21%), and gastroduodenal mucositis (12%), although no major toxicity was encountered. The response rate (CR+PR) among the evaluated patients as determined using CT scans was 67% for colorectal cancer and 73% for gastric cancer. The overall median survival was 12 months and 15 months, respectively. Good local control of liver metastases from the colorectal and gastric cancers was achieved by repeated hepatic arterial infusion chemotherapy employing an implantable port system without the need for hospitalization and without producing major toxicity. Thus, the implantable port system is very useful for the management of patients with unresectable liver metastases.
