In general, progress of chemotherapy for advanced gastrointestinal tumors has been slow, however, introduction of cisplatin has improved the results of chemotherapy in esophageal cancer. Cisplatin has been also recognized to be active for gastric cancer and study of combinations containing it is underway. Adriamycin appears to be the most active for hepatoma and 5-fluorouracil for pancreatic and colorectal cancers. Thus, combinations containing these drugs have been extensively studied but none has shown a definitive superiority over single agent efficacy of both drugs.

There was no direct inhibition of DNA synthesis in ascites hepatoma 22A cells after intraperitoneal injection of single doses of copper (II) complexes with amino acids into tumor-bearing C3HA mice. Meanwhile cis-dichlorodiamine platinum (II) (DDP) as well as sarcolysine showed such inhibition. Copper (II) complexes with alpha-amino acids displayed as significant superoxide dismutase-like activity at concentrations corresponding to therapeutic doses of these compounds. The complexes of copper (II) combined with DDP give an additive antitumor effect in solid tumors of mice.

Thirty patients with metastatic malignancy of various types were treated with cis-diamminedichloroplatinum(II) (DDP) administered by continuous infusion for 120 hours. The starting dose was 20 mg/m2/day (100 mg/m2/course) and was escalated by stages to 40 mg/m2/day (200 mg/m2/course). Dose-limiting toxicity was observed at 30 mg/m2/day (150 mg/m2/course), manifested as marrow suppression and particularly thrombocytopenia in 13 of 14 patients evaluated at doses greater than or equal to 30 mg/m2/day. The gastrointestinal toxicity characteristic of bolus treatment schedules was less intense but was cumulative and dose-related. Renal toxic effects developed in five of 30 patients in spite of adequate hydration and daily diuretic therapy. Peripheral neuropathy developed in the only two patients who received four courses of continuous-infusion DDP. Antitumor effects were observed in six patients (oral cancer, two; lymphoma, one; prostatic cancer, one; hepatoma, one; and bronchogenic carcinoma, one). The recommended starting dose for continuous venous infusion therapy with DDP is 30 mg/m2/day for 5 days.

Patients with unresectable liver cancer (primary and metastatic) were treated with a newly-devised arterial infusion chemotherapy using Cis-DDP and its antidote Sodium thiosulfate (STS). The patients consisted of 4 with primary hepatoma and 1 with metastatic liver cancer originated from intestinal cancer. For the purpose of reducing unfavourable side effects without changing anticancer effect, Cis-DDP was infused into hepatic artery through the catheter while STS being administered systemically. According to Koyama and Saito's criteria, 2 of 5 patients showed partial response (PR) and the others showed no change (NC). The median survival time after onset of therapy was 6.6 months ranging from 2 to 11 months in all the patients. The myelosuppression and renal toxicity, which were considered to be the most serious side effects of Cis-DDP, were not found and liver function was not affected in all the patients. However, all the patients complained of nausea and vomiting. Thus, our experience has indicated that this newly devised infusion chemotherapy is a promising method for treating unresectable liver cancer, although further efforts are necessary for reducing the gastrointestinal toxicity.

We studied the effects of combination chemotherapy of an antitumor drug cis-diamminedichloroplatinum (II) (DDP) and its potent antidote, sodium thiosulfate (STS) in rat liver tumor systems. This therapy was given to female WKA rats with metastatic liver tumors 13 days after inoculation of syngeneic hepatoma cells through the mesenteric vein. DDP and STS were administered via two different routes, hepatic artery and femoral vein, respectively (we call this treatment "two route infusion chemotherapy"). The antitumor effects were evaluated 21 days after the treatment by calculating the tumor weight from the total weight of the liver. Tumor weights of rats treated with 20 mg/kg of intra-arterial DDP plus 1,054 mg/kg of systemic STS (group A), 5 mg/kg of intra-arterial DDP alone (group B), and 5 mg/kg of systemic DDP alone (group C) were, about one fifth, two fifths and three fifths of the tumor weights in the untreated controls, respectively. In group A, no rats died despite administration of a 4-fold higher DDP dose than in the latter two groups B and C in which 14-18 per cent of the rats died, due to DDP-induced toxicity. The patterns of body weight gain in the three groups after the chemotherapy were much the same. Our results clearly indicate that the antitumor effect of DDP on metastatic liver tumors in rats can remarkably be enhanced by the "two route infusion chemotherapy" of DDP and STS.

The antimetastatic effects of two drugs, cis-diamminedichloroplatinum(II) (DDP) and hydrocortisone (liposome-incorporated or free), were studied. The experimental models were regional and distant metastases of hepatoma A and pulmonary adenocarcinoma, which were transplanted into the footpads of A/He mice. Liposomes were prepared from phosphatidylcholine by sonic dispersion. DDP and hydrocortisone were injected sc into the region of the plantar aponeurosis of the foot with the primary tumor. This administration route was considered to be equivalent to the intralymphatic route. Evidence indicated that only liposome-incorporated DDP and hydrocortisone decreased significantly the frequency and growth rate of tumor metastases in the regional lymph nodes. The effect observed was not due to the direct action of the drugs on the primary tumors. When nonencapsulated, these drugs were ineffective. Both liposome-encapsulated and free DDP did not affect distant metastases of pulmonary adenocarcinoma. The intralymphatic administration of liposome-encapsulated antitumor agents is suggested as a method for the prophylactic treatment of tumor metastases in the lymph nodes.

A total of 114 children with solid tumors refractory to conventional therapy were evaluated for response and/or toxic effects after receiving cisplatin at doses of 3.0-4.5 mg/kg with aggressive hydration and mannitol diuresis every 3 weeks; a minimum of two courses was required for evaluation of response (110 patients). Objective responses were noted in 18 patients: rhabdomyosarcoma (three), Wilm's tumor (three), osteogenic sarcoma (three). Ewing's sarcoma (two), neuroblastoma (one), undifferentiated sarcoma (one), hepatoblastoma (one), ovarian teratoma (one), hepatocellular carcinoma (one), embryonal carcinoma of the mediastinum (one), and thymoma (one). Twenty-six patients had some evidence of renal toxicity. Asymptomatic hearing loss was commonly found when audiometry was performed (eight of 18 patients tested). Eight additional patients had symptomatic hearing problems--tinnitus or hearing loss. Myelosuppression was mild. Hypomagnesemia and/or hypocalcemia were common but only one patient had symptoms. Cisplatin, administered at a dose of 3.0 mg/kg with aggressive hydration and mannitol diuresis, is reasonably well-tolerated. Its role in the therapy for those tumors against which it shows activity remains to be determined.

Twenty patients with unresectable hepatocellular carcinoma were treated by intra-arterial subsegmental injection of Cisplatin/4-0-Tetrahydro-Pyranyl-adriamycin Lipiodol suspension (CTLS). The mean single doses of Lipiodol, cisplatin and THP were 2.3 ml, 85 mg and 8.9 mg, respectively. The therapy was given once in 10 patients, twice in 8 and 3 times in two. Over 25% reduction in tumor size was recognized in 12 patients (60%). Fifty or more % decrease of alfa-feto-protein (AFP) was observed in all of 7 patients (100%) with the initial serum AFP level of more than 200 ng/ml. Although transitional and mild symptoms, such as fever, abdominal pain and vomiting were recognized in some cases, no severe complications were encountered. This method is promising as an excellent procedure for unresectable hepatocellular carcinoma.

Eighty patients with inoperable hepatocellular carcinoma (HCC) were treated by transcatheter arterial chemoembolization using an emulsion of Lipiodol and Cisplatin. In 59 patients, gelfoam embolization was also given. The tumour size ranged from 0.5 cm to 33 cm in maximum diameter with the median diameter being 8 cm. The chemoembolization sessions were repeated every 1 1/2 to 3 months. The number of sessions the patients underwent varied from 1 to 11, with the mean number of sessions being 3.7. The HCC either disappeared completely or decreased in size in 44 patients (55%). In patients having an HCC of 12 cm or less in size, 31 out of 41 (75.6%) who had the addition of gelfoam demonstrated decrease in tumour size, while seven out of 11 (63.6%) without the addition of gelfoam demonstrated decrease in tumour size. In patients having an HCC of more than 12 cm in size, only six out of 18 (33.3%) who had the addition of gelfoam demonstrated reduction in tumour size and none of the 10 patients without the addition of gelfoam responded. Thus, HCCs of 12 cm or less in size responded better than larger ones to chemoembolization (P < 0.0001) while the addition of gelfoam enhanced the response (P = 0.039). The 1 year survival rate for the 80 patients was 53% and the 2 years survival rate was 38%. The median survival was 13 months. For patients having an HCC of 12 cm or less in size, the 1 year and 2 year survival rates were 69% and 47% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1990 and January 1996, 39 consecutive patients with histologically improved pT3 or pT4 HCC tumors underwent curative resection (n = 19) or sequential transarterial chemoembolization (n = 20) with a median time interval of 7 weeks up to six times with an emulsion of Lipiodol, Epirubicin and Cisplatin. The 30-day mortality rate for all sessions of TA was 3.8% vs. 21.8% in the resection group (p < 0.05); the cumulative survival rate for the embolization group at 6, 12, 18 and 24 months was 72.3%, 50.1%, 41.2%, 35.4% vs. 42.1%, 31.6%, 31.6% and 14.2% following resection, which cannot be considered statistically significant. Patients with T3 and T4 HCC, treated with sequential embolization or resection, seem to have a comparable survival time.
