Fifteen patients with advanced gastric cancer were treated with the combination of Ftorafur, Adriamycin and mitomycin-C (FAM II). Three patients showed partial responses, in five the disease remained stable for at least 3 months and seven showed progression while on treatment. All responding patients showed survival in excess of 12 months. Hematologic toxicity was of only moderate severity. Median white count nadir was 3500 cells/mm3 and median platelet nadir was 187,000 cells/mm3. Four patients had white count nadirs from 2000--2500 cells/mm3 and three had nadirs from 500--1500 cells/mm3; also there were four with platelet nadirs less than 100,000/mm3. However, no drug-related infections occurred and no platelet transfusions were required. The major non-hematologic toxicities of the regimen were nausea, vomiting, dizziness, vertigo, and rhinorrhea. These toxicities were limiting and resulted in termination of the trial because of poor patient acceptance and the failure of the combination to exhibit a therapeutic advantage over the similar combination (FAM) that employed weekly 5-fluorouracil in place of Ftorafur.

In this study, 139 eligible and evaluable patients with advanced gastric cancer, measurable disease, and no prior chemotherapy were randomized between treatment with Adriamycin alone, 5-fluorouracil (5-FU) plus mitomycin C, and 5-FU plus methyl-CCNU. Objective responses were seen in eight of 37 patients (22%) receiving Adriamycin, in 17 of 53 (32%) receiving 5-FU plus mitomycin C, and in 12 of 49 (24%) receiving 5-FU plus methyl-CCNU. Median durations of response were 4, 3 1/2, and 8 1/2 months, respectively. Sixty-one patients were treated after previous failure to other chemotherapy regimens. Response rates were seen in seven of 47 patients (15%) receiving Adriamycin, in two of nine receiving 5-FU plus mitomycin C, and in one of five receiving 5-FU plus methyl-CCNU. Complete responses were observed more frequently with Adriamycin and with 5-FU plus methyl-CCNU than with 5-FU plus mitomycin C. Although 5-FU plus methyl-CCNU had a slight advantage in interval to disease progression, this was not statistically significant. Median survival for all previously untreated patients was slightly greater than 17 weeks, and there was no meaningful or significant survival difference between the three treatment groups.

In this multi-institutional study of advanced gastric cancer, 141 eligible and evaluable patients were treated with either (a) Adriamycin alone, (b) a combination of 5-fluorouracil, Adriamycin, and methyl-CCNU (FAMe), or (c) a combination of 5-fluorouracil, mitomycin C, and cytosine arabinoside (FMC). In patients with measurable disease and no prior chemotherapy, objective responses were seen in four of 17 patients (24%) receiving Adriamycin alone, in seven of 15 (47%) receiving FAMe, and in three of 18 (17%) receiving FMC. In previously treated patients with measurable disease, objective responses were seen in three of 17 patients (18%) receiving Adriamycin alone and in one of 11 (9%) receiving FMC. In previously untreated patients with both measurable and nonmeasurable disease, FAMe showed a significant advantage over both Adriamycin alone and FMC with regard to interval to disease progression and survival. In comparing Adriamycin alone with FMC in previously treated patients, intervals to disease progression and survival were essentially identical.

While carcinomas of the stomach is decreasing in incidence in the Dnited States, it is still a major cause of cancer death. But gastric neoplasms are not decreasing in some other geographic areas. According to some studies, 30% of all cancer in the U.S.S.R. originates in the stomach. The rate of gastric neoplasms is greatest in Japan, and over 54% of all cancer in the male population arises in the stomach. The peak age for development of stomach cancer is between 70 and 80 years; over 60% of all stomach cancer is diagnosed in patients between the ages of 60 and 70, while more than 10% is found in those over 80. The main hope for cure at this time rests with surgical treatment. However, despite increased use of surgery, the 5-year survival rate of approximately 13% for patients diagnosed during 1955-59 has not improved to any degree since that time. The major drugs commonly used to treat gastric cancer are 5-fluorouracil (5-FU) and mitomycin C. Controversy still exists concerning the optimum method for administering 5-FU, the most frequently used drug in the United States. The standard loading-course method was attended by a high risk of severe toxicity and drug-related deaths. Several variations of the loading course have evolved. Currently, the Mayo Clinic group uses a 5-day course of 13.5 mg 5-FU/kg repeated every 5 weeks, with therapy interrupted if stomatitis or diarrhea develops; with this regimen the drug-related mortality rate was reported to be less than 1%. Studies have shown that 5-FU plus radiotherapy can enhance survival in patients with locally unresectable diseases. The overall objective with 5-FU is 20-25% with an average of 4-5 months' duration of response. Despite the many patients treated with 5-FU, rarely has a systematic analysis been done of factors such as age, sex, disease-free interval, histologic grade of the tumor, or sites or metastases, which might predispose to a favourable or unfavorable response. In Japan the most commonly used drug for treatment of gastric cancer is mitomycin C, the second most frequently used drug in the United States. The overall objective response rate with mitomycin C is between 20 and 30%, with the higher response rates being reported in the Japanese data. The average duration of response ranges from 1 to 3 months. The nitrosoureas [1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), 1,3-cis(2-chloroethyl)-1-nitrosourea (CCNU), and methyl CCNU (MeCCNU)] have shown some evidence of activity against gastric cancer. BCNU has yielded an objective response rate of 18% (6/33) and an average duration of response of 4.5 months in gastric cancer patients, most of whom had no prior therapy. Adriamycin recently has been shown to have some antitumor activity, with an approximate response rate of 25%. Combination approaches have been more successful in stomach cancer than in any other gastrointestinal neoplasm. The Japanese have reported higher response rates with a combination of 5-FU, mitomycin C, and cytosine arabinoside...

Thirty-six patients with advanced measurable gastric cancer were treated with a new combination chemotherapy program consisting of 5-fluorouracil, Adriamycin and mitomycin-C (FAM). Fifty percent of patients achieved an objective partial response. The median duration of remission was 9.5 months and the median survival for responding patients was 13.5 months, with 2 remaining alive at 14 and 26 months. The median survival for nonresponding patients was 3.0 months and all were dead by 6 months after initiation of therapy. The median survival of all 36 patients treated with FAM was 5.5 months. An analysis of possible prognostic variables including initial performance status, resectability of the primary gastric tumor and histologic differentiation of the neoplasm failed to account for differences in patient response and survival. The FAM regimen was well tolerated, and produced only moderate bone marrow suppression. These results demonstrate that some patients with advanced gastric cancer can be effectively palliated with FAM chemotherapy. Phase III trials are warranted to assess the effect of the FAM regimen on the survival of patients with advanced gastric cancer.

Adriamycin has not been as extensively evaluated in Japan as in some other countries. This is due both to the widespread use of mitomycin C and importantly to the alopecia caused by adriamycin being particularly disturbing to Japanese patients. Japanese studies have shown the drug to be highly active in tumors such as stomach cancer (31/92), lung cancer (27/84), and malignant lymphomas (15/46). Combination studies have been mainly with 5-FU although others have also been investigated. Other approaches which have been studied include intraarterial infusion, local application in bladder cancer, intrapleural application and in the treatment of childhood malignancies.

Adriamycin (ADM), an anthracycline cytotoxic agent, was conjugated with monoclonal antibody 3H11 against gastric cancer via the dextran bridge method. The conjugate 3H11-DEX-ADM, with molar ratio of 3H11 to ADM being 1:73, retained antibody activity to 86%. In the cytotoxicity assay, 3H11-DEX-ADM was shown to exhibit increased cytotoxicity against the target cell line BGC 823. Its IC50 was 3.75 fold less than that of free ADM. The antitumor effect of the conjugate was evaluated in tumor-bearing nude mice. The results indicate that the specific antibody conjugate 3H11-DEX-ADM can significantly inhibit the tumor growth. At the dosage level used in the present study (5 micrograms/mouse x 6), 3H11-DEX-ADM showed an inhibition rate of 51.5%, whereas only moderate inhibition rates were observed with free ADM and the control conjugate NIgG-DEX-ADM. In addition, experiment was performed to evaluate the combined cytotoxicity of 3H11-DEX-ADM and the conjugate of mitomycin C (3H11-HSA-MMC) at different ratios. It was shown that the combination has no synergistic effect when their IC50 was compared with that of the two conjugates used alone. The same result was observed on combinations of the two corresponding free drugs.

Between 1985 and 1990, 50 patients with unresectable liver metastases from colorectal cancer and 34 subjects with metastases from gastric cancer were treated by repeated hepatic arterial infusion chemotherapy employing an implantable prot system. A catheter was inserted into the hepatic artery via the left subclavian artery and was connected to the implantable injection port in each patient. 5-Fluorouracil (5-FU) at 330 mg/m2 per week (167 mg/m2 daily given continuously over the initial 3 months for colorectal cancer), Adriamycin (ADR) at 20 mg/m2 every 4 weeks and mitomycin C (MMC) at 2.7 mg/m2 every 2 weeks were given to all 34 patients with gastric cancer and to 31 of the colorectal cancer patients. The remaining 19 patients with colorectal cancer received 5-FU at 1,000 mg/m2 every week. As a rule the treatment was performed on an outpatient basis. The side effects and complications observed included myelosuppression (23%), hepatic arterial occlusion (21%), and gastroduodenal mucositis (12%), although no major toxicity was encountered. The response rate (CR+PR) among the evaluated patients as determined using CT scans was 67% for colorectal cancer and 73% for gastric cancer. The overall median survival was 12 months and 15 months, respectively. Good local control of liver metastases from the colorectal and gastric cancers was achieved by repeated hepatic arterial infusion chemotherapy employing an implantable port system without the need for hospitalization and without producing major toxicity. Thus, the implantable port system is very useful for the management of patients with unresectable liver metastases.

Forty-four patients with unresectable liver tumors including 25 colorectal cancers, 7 gastric cancers, 6 breast cancer, and 6 other diseases, were treated by intra-arterial infusion chemotherapy using an implantable reservoir. The catheter was placed in hepatic artery via left subclavian artery or by direct insertion at laparotomy. Adriamycin, epirubicin or cisplatin were administered intermittently. Response rate was 31.8% for colorectal cancer, 42.9% for gastric cancer, and 60.0% for breast cancer, averaging 37.5% for all cases. Response in colorectal cancer tended to be higher for cases of H2, well-differentiated adenocarcinoma, and v(-). Response was also validated by survival time and changes in CEA. In a few patients, metastatic lesions could be resected after this treatment. Our results indicate that in combination with an aggressive surgical procedure, this treatment may improve the prognosis of patients with metastatic liver tumors.

Chemotherapy targeting the regional lymph nodes for gastric cancer may be more effective preoperatively than postoperatively since anticancer drugs can be transported to the regional lymph nodes via the lymphatic flow through the stomach. Distribution of Adriamycin (ADR) among the various organs was assessed following its intravenous injection in rabbits. The delivery index of the drug to each organ was assessed by the ratio of the area under the concentration-time curve (AUC) of each organ to the AUC of the regional lymph nodes following the intravenous administration. The delivery index was 0.14 for the stomach, 0.11 for the heart, 0.53 for bone marrow, 0.74 for the spleen, and 0.14 for the liver. These data suggest that preoperative adjuvant chemotherapy by intravenous administration of ADR may be effective in targeting ADR at the regional lymph nodes. Tissue ADR concentrations in the regional lymph nodes were assessed following gastric submucosal administration of ADR in rabbits. The targeting index for the regional lymph nodes was 8.20, measured by the ratio of AUC following a gastric submucosal injection to AUC after the intravenous injection of ADR. This suggests that it may be possible to selectively target chemotherapy to regional lymph nodes by employing a gastric submucosal administration of ADR.
