[Chemo-embolization therapy of unresectable liver metastases using implantable infusion port].
Since 1987, 14 patients (10 colorectal, 3 gastric and 1 lung cancer) with unresectable liver metastases received intra-arterial infusion chemo-embolization therapy using implantable infusion port. All patients had more than one lesion in bilateral lobe (H2 and H3). Infusion catheters were placed in the proper hepatic artery through the gastroduodenal artery on laparotomy. Infusion ports were implanted in the subcutaneous tissue of the abdominal wall. Various kinds of chemotherapeutic agents such as MMC, ADR, THP-ADR, CDDP and 5-FU were injected with embolization material (DSM or Lipiodol), every 1 to 4 weeks at the outpatient clinic. Among 10 cases of H2 grade metastases, 1 CR and 3 PR (40% clinical response) were obtained. However, all 4 cases of H3 grade were judged PD. All patients except one with H2 grade metastases are still alive, but 3 out of 4 with H3 grade died within 7 to 11 months. Catheter occlusion was observed in 4 cases for 3 to 7 months. Infection around the port occurred in 1 patient. A patient with metastatic liver cancer was treated by intermittent bolus injection with MMC and DSM. Partial response was confirmed by CT and tumor markers. Histological response was demonstrated in the specimen obtained at partial hepatectomy. It is concluded that this treatment is variable to prolong the survival of patients with H2 grade metastatic liver cancer, together with maintenance of the quality of life.
