Arterial infusion chemotherapy is commonly-used modality for controlling cancers located in specific regions. Previously we described a new method of intra-hepatic arterial catheterization through the left subclavian artery using a subcutaneously-implanted silicone reservoir. In the present paper, we report our experience using a low dose-intermittent intraarterial (i.a.) infusion chemotherapy. Since February, 1982, 70 patients including 44 cases of metastatic liver cancer, 16 cases of primary hepatocellular carcinoma and 10 cases of other gastrointestinal malignancies, have been treated with this low dose-intermittent i.a. infusion chemotherapy, the drugs used being as follows. 1) MMC 4 mg, 5-FU 500 mg, AraC 40 mg/2w, 2) MMC 4 mg/w, 3) 5-FU 500 mg/w, MMC 4 mg/2w, ADM 30 mg/4w. Here, we briefly review the effectiveness of this modality for controlling regional diseases including liver metastases. The average hospital-free interval was 156 days and partial responses were observed in 43% (21/49) of cases. Side effects during the therapy were only mild bone marrow suppression and anorexia, which were tolerable in out-hospital care. We also studied the pharmacokinetics of i.a. infusion into the liver in comparison with i.v. infusion using 99mTc-RBC, and found that the ratio of i.a. to i.v. with regard to trans-arterial drug delivery to the liver was 10.0. From the viewpoints of first pass effect and increased local concentration theory, this ratio suggests that the effectiveness of a low-dose anti-tumor agent administered intraarterially is not so low. Accordingly, we believe that low dose-intermittent i.a. infusion chemotherapy is beneficial as an induction and maintenance chemotherapy for patients with regionally located cancers because it is effective, safer and prolongs the hospital-free interval.

407 cases of unresectable hepatocellular carcinoma (HCC) occurring from 1970 to March 1985, including 107 cases receiving conservative therapy, 176 cases receiving one-shot therapy and 124 cases receiving transcatheter arterial embolization (TAE) therapy, were studied and the efficacy of chemotherapy was compared with that of TAE therapy. The results were as follows; One-year survival rate was 2.8% with a median survival time of 1.3 months in conservative therapy. In the 176 cases of one-shot therapy, one-year survival rate was 21.0%, two-year 6.8% and three-year 2.3% and the median survival time was 4.8% months. In 120 cases of one-shot therapy which were compatible with criteria for one-shot injection of anticancer drugs via the hepatic artery for HCC, one-year survival rate was 30%. However the rate was 1.8% in 56 cases which were not compatible with the criteria. In 37 cases in which Mitomycin C (MMC) and Adriamycin (ADR) were administered alternately, one-year survival rate was 41.7%, two-year 16.1% and three-year 4.3%. The highest survival rate was obtained by TAE therapy. One-year survival rate was 66.9%, two-year 33.8% and three-year 28.9%. Decrease of AFP after therapy was noted in 42.4% of cases given one-shot therapy and in 95.2% of cases given TEA therapy. The results suggest that alternate administration of anticancer agents produces good chemotherapeutic effects and that the best life-prolongation is obtained by TAE therapy.

The studied patient (70 years old, male) had primary hepatoma with rupture of the liver. We resected his left lobe partially and were able to save him. Since a residual tumor was found after surgery, we injected a total of 30 mg of MMC into the SCA 3 times. Under continuous administration of OK-432, the patient survived for 3 years and 6 months in remission. Because the tumor grew gradually, we started a multi-drug immunotherapy (OK-432 5 KE/2 W/intradermal, PSK/3.0 g/day/P.O., SPG/20 mg/2 W/I. M.) which we have advocated. In 6 months the tumor regressed to 1/3 of its original size. The patient is currently in good condition 4 years and 7 months after the operation. This case demonstrated the superiority of multi-drug immunotherapy over single-drug immunotherapy.

Four patients with advanced hepatocellular carcinoma, but with stage I functional disease, were treated with intrahepatic arterial lipoidal mixed with small doses of Adriamycin (20 mg) and Mitomycin C (10 mg). Regression was seen in 3 out of the 4 patients. In 2 patients, there was substantial regression of tumour clinically, radiologically and biochemically. The treatment was tolerable without marrow depression or deterioration of liver function. Mild fever (37 degrees C) was seen in 2 and epigastric pain in 1. This form of treatment opens up scope for further improvement in the management of irresectable hepatocellular carcinoma.

The lipid lymphographic agent, Lipiodol ultrafluid has been found to remain selectively in hepatocellular carcinoma. Using this characteristic nature of Lipiodol, a new targeting anticancer chemotherapy was devised. In order to achieve targeting anticancer chemotherapy and useful anticancer effects, anticancer drugs must be dissolved or suspended in Lipiodol and diffuse out from the Lipiodol gradually. Oily anticancer agents such as SMANCS dissolved in Lipiodol (SMANCS/Lipiodol), Mitomycin C in Lipiodol (MMC/Lipiodol), Aclarubicin in Lipiodol (ACR/Lipiodol) and a mixture of these were administered by catheterizing the celiac or hepatic artery under X-ray monitoring in 216 patients with hepatocellular carcinoma. Remarkable anticancer effects of this targeting chemotherapy were achieved, the serum AFP level and tumor size both showing a decrease in 91% of cases. The survival period of patients with unresectable hepatoma treated with the present protocol was definitely longer than the comparison group.

A new method of chemoembolization with degradable starch microspheres (DSM) was used for patients with malignant hepatic tumors. DSM, 40-45 micron in diameter, which are degraded by serum amylase, temporarily obstruct arterial blood flow at the arteriolar capillary bed. Experimental studies have demonstrated that such occlusion enhances the regional uptake and reduces systemic exposure to simultaneously administered arterial anticancer drugs. Transcatheter chemoembolization with DSM was performed in 14 cases of hepatocellular carcinoma and 8 cases of metastatic liver cancer. Adriamycin or Mitomycin C mixed with DSM was injected into the patients with hepatocellular carcinoma or metastatic liver cancer, respectively, through the proper hepatic artery. The therapeutic effect of this chemoembolization was evaluated by the change in tumor size measured by angiography or computed tomography. In hepatocellular carcinoma, tumor regression of over 50% was observed in 5 of 14 patients. Elevated serum AFP level of more than 200 ng/ml was decreased in all 6 cases. In metastatic liver cancer, tumor regression of over 50% was observed in 4 of 8 cases. Although half of the patients had transient pain within 2 hours, no major side effects such as bone marrow suppression and hepatotoxicity were observed. Our results suggest that chemoembolization with DSM can be effectively used in the treatment of malignant hepatic tumors.

A retrospective comparative study was done on the management of hepatoma: MMC-mc-chemoembolization therapy (group A; 9 patients) vs. the same therapy in combination with UFT as a maintenance therapy (group B; 8 patients). The six-month survival rate was 44.4% for group A, and 87.5% for group B. Generalized Wilcoxon test for the whole period revealed that the survival was favorable for group B as compared with A (P = 0.048). For adverse reactions in UFT therapy, no subjective signs occurred, but objective ones appeared such as one case of leukocytopenia, one of thrombocytopenia and 3 of increased GOT. However, no cessation of UFT therapy was necessary in these patients. These findings suggested that maintenance therapy with UFT may be favorable in this type of treatment for hepatoma.

Effects of reduction surgery combined with chemotherapy on DAB induced hepatoma were investigated. DAB hepatoma was transplanted in the liver and subcutaneous tissue of rats. The results were as follows; 1. Reduction surgery prolonged the survival time of rats with DAB induced hepatoma, either in liver (5, 7 days, p less than 0.001) and subcutaneous tissue(15.9 days, p less than 0.01). 2. Synchronization chemotherapy with MMC and ADM showed inhibitory effect on cell growth in the cultured human hepatoma cells. (p less than 0.01) 3. Reduction surgery with combined chemotherapy prolonged the survival time 3.9 days compared with reduction surgery only. (p less than 0.05) In conclusion, it was suggested that reduction surgery with synchronization chemotherapy is beneficial for improvement of the prognosis in patients with unresectable hepatic tumors.

Mitoxantrone is similar to Adriblastin in its mechanism of action and antitumor activity. Objective remissions were obtained in 20-30% pretreated patients and in 23-44% of untreated patients by single-drug treatment of patients suffering from metastatic breast cancer. The objective response rates to Mitoxantrone in combination with CTX, 5-FU, MTX, VCR, MMC. Prednimustine or Vindesine were 16-46% in treatment and 38-89% in primary treatment. Randomized studies comparing Mitoxantrone with Adriblastin in single-drug and combination treatment did not show any significant differences in efficacy. However, Mitoxantrone was significantly less toxic. Remission rates of between 24 and 54% were achieved by single-drug treatment in pretreated patients suffering from non-Hodgkin lymphoma. Mitoxantrone appears to be active in ovarian cancer, lung cancer and hepatocellular carcinoma.

Chemosensitivity of liver cell carcinoma was studied by subrenal capsule assay. The method of assay was based on Bogden's one, but the antitumor activity was evaluated by tumor growth inhibition rate (TG-IR). The anticancer agent with more than 50% TG-IR was judged as positive in the chemosensitivity test. Of 3 human hepatoma cell lines transplanted in the subcutaneous space of nude mice, all of 3 were evaluable. The positive rates of ADR, MMC, CDDP, 5-FU and CPA were 66.7%, 100%, 66.7%, 100% and 0%, respectively. Of 24 patients who provided fresh tumor specimens for the assay, 12 (50%) were evaluable. The positive rates of ADR, MMC, CDDP, 5-FU and CPA were 25%, 16.7%, 16.7%, 33.3% and 8.3%, respectively. Our study suggested that 5-FU, MMC and ADR were comparatively active against the hepatoma cell, CDDP was less active than these 3 agents, CPA was inactive. These results seem to justify the use of current anticancer agents against hepatic cell carcinoma and indicate the usefulness of SRC assay for selecting chemotherapeutic agents against liver cell carcinoma.
