    Abstract:
    Fifty-four patients with unresectable malignant liver tumors (14 of hepatocellular carcinoma, 40 of metastasis to the liver from gastric or colo-rectal cancer) were treated with intra-hepato-arterial (IHA) injections of cis-diamminedichloroplatinum (II) (CDDP) plus 5-fluorouracil (5-FU). In 32 of the patients, the liver tumors were detected synchronously with the diagnosis of the primary cancers, which were resected palliatively. Therapeutic schedules consisted of bolus injections of CDDP (50 mg/body/week) and 5-FU (250 mg/body/day) [Regimen I], and CDDP (50 mg/body/10-14 days) and 5-FU (100 mg/body/day) [Regimen II]. In 48 patients treated with IHA chemotherapy only, a partial response (PR) was obtained in 6 of 14 (43%) evaluable patients for Regimen I and in 11 of 30 (37%) patients for Regimen II. The dose-limiting factor for treatment with CDDP was bone marrow toxicity, but this toxicity was remarkably alleviated in Regimen II without any decrease in antitumor effectiveness. In 13 patients, other modalities, such as total-body hyperthermia (4 patients), radiofrequency capacitive local hyperthermia (5), and temporary arterial embolization (4), were combined with IHA chemotherapy. PR was obtained in 7 of 13 (54%) patients with the combined therapy. This combined therapy was efficacious in 7 patients in whom no desired results were obtained by IHA chemotherapy only. The survival rate was 50% at 12 months. IHA chemotherapy with CDDP plus 5-FU, especially when according to Regimen II, appears to be a strongly recommended strategy for treatment of unresected primary or metastatic liver tumor. Further, addition of the hyperthermia or the arterial embolization might enhance the antitumor effect of IHA chemotherapy.
