Antitumor polyoxomolybdates have been recognized in the course of study on the medical utilization of polyoxometalates, inorganic polymers of metal oxide. [NH3Pri]6[Mo7O24].3H2O (PM-8) was found as a representative of antitumor polyoxomolybdates. The growth suppressions of PM-8 against Co-4 human colon cancer xenografted under the subrenal capsule in cd-1 mice were equal or superior to that of 5-FU, MMC, ACNU, ADM and CDDP. Potent antitumor activity of PM-8 is also established against MX-1 human breast and OAT human lung cancer xenografted in athymic nude mice. Polyoxomolybdate is a new type of antitumor substance.

Nineteen patients with metastatic liver tumor (9 of gastric cancer, 5 of colon cancer, 2 of pancreatic cancer, one each of mammary cancer, cholecystic cancer, carcinoid of biliary tract) and one patient with primary liver cancer were treated by endogenously induced LAK therapy consisting of transhepatic arterial infusion with ADM or MMC for induction therapy and OK-432 and rIL-2 (TGP-3) for immunotherapy. The following results were obtained. 1) Clinical response for liver tumor showed no CR but 8 cases of PR, for an overall response rate of 42.1%. 2) Reduced tumor marker value was noted in 76.5% cases, and 50% survival term became 349 days after the therapy. 3) Many CD4 and CD8 positive mononuclear cells had infiltrated around liver tumor after therapy by immuno-histochemical staining of surface marker. 4) NK activity of peripheral blood lymphocytes was markedly reduced soon after the therapy and continued for about 4-7 days, while in cases of combined subcutaneous administration with OK-432, NK activity showed only a slight decrease.

Liposomes as drug carriers in cancer chemotherapy have attracted considerable interest. To enhance the therapeutic effect of Adriamycin entrapped in liposomes (Lip-ADM) on human solid tumors, we investigated the therapeutic effects of Lip-ADM in combination with recombinant human tumor necrosis factor-alpha (rTNF-alpha), which is known to have specific effects on tumor vasculature. rTNF-alpha or saline solution was injected intravenously into nude mice bearing a human colon cancer strain, HC-1, at 1 hour before intravenous administration of Lip-ADM. The significant therapeutic effect of Lip-ADM in combination with rTNF-alpha was demonstrated by the evaluation with tumor growth curve and the actual tumor weights, in comparison with groups of mice treated with saline solution, rTNF-alpha alone, or with a Lip-ADM after saline. Levels of Adriamycin in tumor tissue in the Lip-ADM in combination with rTNF-alpha-treated group were higher than those in Lip-ADM with saline solution-treated group.

We studied the effects of liposome-entrapped adriamycin (L-ADM) administered via the portal vein and the clinical application of this treatment in the therapy and inhibition of liver metastasis, experimentally and clinically. Liposomes composed of egg phosphatidylcholine (cholesterol 50 mol%) were used as drug carriers. We examined the distribution in tissues and antitumor effect of freeze-dried L-ADM administered via the portal vein to rabbits bearing VX2 tumors. The liver concentration of ADM increased after delivery and cardiac uptake decreased compared with free drug treatment. The life span was prolonged by L-ADM treatment compared with the control group and the free ADM group. This L-ADM administration was confirmed to be safe and revealed a decrease in the heart toxicities compared with free adriamycin. Nineteen cases were studied from Jan. 1986 to May 1991 via the portal vein and the clinical effects were evaluated. From Mar. 1988 to date, 10 cases were treated with L-ADM (20-30 mg every 2 weeks/body) in patients with inoperable cases using subcutaneously implanted reservoir. The median survival was 450 days; 275 days for colon cancer, 492 days for gastric cancer, and 1,052 days for uterine cancer (range: 136-1,152 days), compared with 141 days (range: 52-253 days) in 9 cases of historical control treated with free-ADM via the portal vein. These results suggest that chemotherapy via the portal vein with L-ADM for metastatic liver cancer may increase survival time.

A randomized controlled study was carried out by the envelope method with 491 institutions in participation across the country in order to find an optimal surgical adjuvant chemotherapy for curatively resected colorectal cancer. The schedules for drug administration were different in four districts: ACNU + Futraful (FT) group and FT alone group in the Hokkaido-Shikoku district; the same schedule groups plus untreated group in the Chubu-Kinki district; MMC+FT group, FT alone group in the Tohoku-Kanto district; and ADM+FT group and FT alone group in the Chugoku-Kyushu district. The numbers of patients admitted to this study were 2,450 cases with colon cancer and 2,456 cases met the evaluation criteria of this study. The 5-year survival rate on the whole did not differ from combination therapy to single drug therapy in either colon cancer or rectal cancer, but in Dukes C rectal cancer the five-year survival rate tended to be higher with the combination therapies. In n2 (+) or a2(s) rectal cancer in particular, combination therapies with MMC and FT and with ADM and FT achieved significantly higher five-year survival rate, and the rate of local recurrence was significantly lower with ADM+FT.

In order to improve therapeutic efficacy for metastatic liver cancer, intermittent transarterial administration of BRM in combination with anticancer drugs was performed by use of reservoir apparatus. A total of 22 patients (12 cases of gastric cancer, 6 of colon cancer, 2 of pancreas cancer, 1 of gall bladder cancer and 1 of biliary tract carcinoid) were treated according to the following schedule: both 10 mg of ADM (or MMC) and 0.5 KE (or 1.0 KE) of OK-432 were administered on day 1 and 40 x 10(4) JRU of recombinant interleukin 2 (r-IL 2) on day 4, 7 and 11. The treatment was repeated as many times as possible. In terms of direct antitumor effect and decrease of tumor marker, the response rate was 43% (6 cases out of 14) and 75% (9 cases out of 12), respectively. As for performance status, improvement, no change and deterioration were seen in 4 cases, 8 cases and 3 cases, respectively. Even though 13 patients died, 8 of them survived more than 300 days. In the case of gastric cancer patients with liver metastasis, 50% survival time of 12 cases was 334 days, while that of 30 cases, who were administered anticancer drugs only systemically, was 144 days. In 3 cases the decrease in the size of tumors located in both liver and the other metastases also was seen. Every case developed high grade fever, but an antifebrile was effective. Otherwise severe side effects were not seen. These results indicated that intermittent arterial infusion immunochemotherapy was feasible for the treatment of metastatic liver cancer.

Reversal of multidrug drug resistance (MDR) has been achieved in vitro by a variety of agents including verapamil, quinidine, cyclosporine A, and amiodarone. The toxicity of these agents precludes the achievement of sufficient levels in the serum to circumvent efficiently the MDR in vivo. The authors previously demonstrated that quinine, the widely used antimalarial agent, is able to reverse primary resistance of rat colon cancer cells to anthracyclines. In this report, the efficiency of quinine formiate in reversing the doxorubicin (ADM) (Adriamycin, Adria Laboratories, Columbus, OH) resistance of the well-defined MDR human leukemic cell line K562/ADM was demonstrated. In culture medium, quinine is slightly less effective than verapamil in increasing the cytotoxicity and uptake of ADM when both drugs are used at the same concentration. A nontoxic dose of 5 micrograms/ml is necessary to reverse the MDR in K562/ADM cells. In patients receiving quinine formiate in a continuous intravenous infusion, a significant correlation (r = 0.84) was found between the serum levels of quinine and the ability of sera to increase ADM uptake in K562/ADM cells. When quinine is administered at a conventional dose (25 to 30 mg/kg/d), serum levels consistently reach more than 8 micrograms/ml without severe side effects; ear noises and vertigo are the dose-limiting side effects. At these concentrations, quinine induces a more than double increase in ADM uptake in K562/ADM cells. Pharmacokinetic data indicate that quinine should be administered 24 to 36 hours before anti-cancer drugs in clinical trials that test its efficiency as a modifier of MDR in human hematologic malignant neoplasms.

Thirty four patients with advanced gastric cancer (GC), colon cancer (CC) biliary tract cancer (BC) and pancreatic cancer (PC) were treated with a combined chemotherapy of UFT with ADM (UFT-A), or UFT with ADM and CDDP (UFT-AC). The UFT-A regimen consisted of UFT, 600 mg/body daily. As for ADM, 10 mg/body was given intravenously from day 1-4 and repeated every two weeks. The UFT-AC regimen consisted of UFT 400-600 mg/body daily. As for ADM, 7.5 mg/m2 was given from day 7-9 and CDDP 50 mg/m2 on day 7, repeated every 3-4 weeks. Partial responses (PR) were seen in 7 cases (36.8%) (5 cases of GC, 1 case of CC and 1 case of BC) out of 19 evaluable patients (8 cases of GC, 4 cases of CC, 4 cases of BC and 3 case of PC) treated with UFT-A. Complete response in a case of CC and PR in 6 cases (47.7%) (3 cases of GC and 3 cases of BC) were observed out of 15 evaluable patients (7 cases of GC, 2 cases of CC, 4 cases of BC and 2 cases of PC) treated with UFT-AC. There was no significant difference of survival curve between the two regimens, however, the median survival of responders for both regimens is longer than non-responders with statistical significance. As for side effects, UGI symptoms were recognized in 37% of UFT-A group and in 73% of UFT-AC group. A leukopenia count of less than 2,000/mm3 appeared in 11% of UFT-A group and in 20% of UFT-AC group. Considering these results, UFT-A and UFT-AC therapy appears to be useful in cases of advanced gastrointestinal cancer, especially gastric cancer.

To evaluate the efficacy of surgical adjuvant chemotherapy for patients with curatively resected colorectal cancer (excluding m and sm cancer), a randomized controlled study was performed from January 1982 to October 1983. The schedules for drug administration were different in four districts, and four randomly assigned protocols were studied using tegafur (FT), ACNU, MMC and ADM. A total of 4,906 cases from 491 institutions were entered and 4,206 cases were varied for the study. There were no significant differences in 3-year survival rate in each district protocol. According to Dukes C for rectal cancer patients, ADM + FT group was higher than the FT only group in 3-year survival rate (p = 0.092) and had a significantly longer survival than FT only group in 3-year disease-free rate (p = 0.011). The rate of local recidivation in colon cancer resected curatively was higher in ACNU + FT group than in FT only group (p less than 0.05). A tendency for decreased liver metastasis was observed in FT group compared with the control group, and liver metastasis of ADM + FT group was lower than that of FT only group. No serious adverse effects were observed in any protocol.

A liposome-entrapped liposome form of Adriamycin (Lip-ADM) has been demonstrated to cause less myocardial and gastrointestinal toxicity than free ADM. In the present study, Lip-ADM prepared by the remote loading method was administered to 3 patients with metastatic adenocarcinoma of the liver via a reservoir with the catheter located in the proper hepatic artery. The primary tumor was gastric cancer in 2 patients and sigmoid colon cancer in 1. Lip-ADM was administered at doses of 10, 20 or 50 mg per time. The total ADM dose was 170, 490, and 760 mg, respectively. No severe adverse effects, such as nausea, vomiting, stomatitis, alopecia or cardiotoxicity, were observed in any of the patients. Although mild leukocytopenia (2,800/microliters) was observed in 1 patient, anemia or thrombocytopenia did not occur. The survival time was respectively 6, 15, and 17 months from the start of Lip-ADM administration. A partial response was obtained in 1 patient and stable disease in 1 patient. Administration of Lip-ADM via a reservoir appears to be a useful treatment for patients with metastatic adenocarcinoma of the liver, since the low toxicity of this preparation allows an increase of the total dose of ADM.
