A multicenter cooperative study was conducted from July 1984 to March 1986 to evaluate the clinical efficacy of sequential MTX-5-FU treatment in 96 cases of advanced gastric cancer and 39 cases of colorectal cancer. 5-FU 600 mg/m2 i.v. was given and MTX 30 mg/m2 (A), 100 mg/m2 (B) and 300 mg/m2 (C) i.v. were given, and the administration interval between MTX and 5-FU was 1 to 3 h for the gastric cancer group, and 7 h for the colorectal cancer group. Leucovorin rescue of 10 mg/m2 p.o. was given 24 h after MTX administration. In the gastric cancer group, the response rate for Regimen A was 23.2% (CR 1 and PR 12) out of 56 evaluable cases, and for Regimen B, 40.5% (CR 1 and PR 14) out of 37 evaluable cases. In the colorectal cancer group, the response rate for Regimen A was 28.6% (PR 6) out of 21 evaluable cases and for Regimen B, 20.0% (PR 3) out of 15 cases. Median survival time for the gastric cancer group was 5.5 months with Regimen A and 7.6 months with Regimen B, and for the colorectal cancer group 10.9 months with Regimen A and 7.9 months with Regimen B. Main adverse effects were marrow impairment and gastrointestinal symptoms such as nausea, diarrhea, and stomatitis. In this study Regimen B showed relatively good results. In order to evaluate the biochemical modulation occurring with sequential MTX-5-FU treatment, a further phase III study in gastric cancer patients should be conducted.

Preoperative cancer chemotherapy for gastric cancer was reviewed with special emphasis on histologic findings and survival. Preoperative chemotherapy with intravenous, split administration of MMC 40 mg caused considerable damage to "micro-solitary metastatic foci" in metastatic lymph nodes. In view of the lipid-adsorbing ability of the lymphatic stream, emulsified 5-FU was used orally in 182 patients with gastric cancer; histologic findings revealed that the emulsified 5-FU enhanced the antitumor efficacy for metastatic lymph nodes as well as the primary lesion. However, the 5-year survival rate for gastric cancer patients undergoing preoperative emulsified 5-FU therapy did not differ from the control, with only the exception of patients with Stage III gastric cancer. On the other hand, combined therapy involving preoperative intra-arterial infusion and surgery was carried out in 62 patients with gastric cancer. These preoperative treatments using MMC, 5-FU, VLB, MTX and/or cytosine arabinoside entailed continuous infusion for 15 to 20 hours; the histologic changes observed revealed marked antitumor effects on the primary focus as well as metastatic lymph nodes. The five-year survival rate for the 62 patients was compared with that for 99 patients with gastric cancer in the corresponding period. The survival rate was analyzed based on the degree of serosal invasion. The overall survivals in the 62 patients were higher than those in the controls for the first 3 years. At 4 to 5 years, the survival rates for both the treated and control groups were approximately equal. In patients without serosal invasion, the survival rates were higher in treated cases than in the controls for the first 2 years. Thirty-nine patients with serosal invasion had significantly higher survival rates than the controls for the first 3 years. The survival rates for the treated patients with cancerous infiltration of ther organs were about the same as those for the corresponding control patients.

We encountered a case of non-curatively resected gastric cancer (p1, n4) who responded well to sequential MTX/5-FU therapy and PMUE therapy. A 63-year-old man was admitted to our hospital with complaints of nausea and vomiting. Upper gastrointestinal examination and CT scan revealed Borrmann type 3 gastric cancer with pyloric stenosis and multiple paraaortic lymphnodal metastasis. The patient underwent palliative gastrectomy for extensive gastric cancer (H0, P1, N4, T3, Stage IV b). Histological examination of the resected stomach revealed poorly differentiated adenocarcinoma with paraaortic lymphnodes metastasis (n4) and peritoneal dissemination (p1). Chemotherapy with sequential MTX/5-FU was given 13 times. Ten months after the operation, abdominal pain and back pain required analgesic treatment. Abdominal CT scan revealed increased size of paraaortic lymphnodes, suggesting recurrence. Sequential MTX/5-FU therapy was switched by PMUE therapy. Lymphnode size became smaller and habitual analgesics could be discontinued. Since then he was given MTX/5-FU and PMUE therapies alternately on an ambulant basis. The patient resumed his daily activities at 2 years and 8 months after the operation.

A phase III randomised study, comparing treatment with fluorouracil, epidoxorubicin and methotrexate (FEMTX) with the best supportive care, was conducted in patients with unresectable or metastatic gastric cancer. During the period from July 1986 to June 1992, 41 patients were randomised to receive FEMTX or best supportive care. MTX was given in a dose of 1500 mg m-2 intravenously (i.v.) followed after 1 h by 5-FU 1500 mg m-2 i.v. on day 1; leucovorin rescue was started after 24 h (30 mg orally every 6 h for 48 h) and epidoxorubicin 60 mg m-2 i.v. was administered on day 15. In addition both groups received tablets containing vitamins A and E. Response rates for FEMTX were as follows: complete response (CR), 19% (4/21); partial response (PR), 10% (2/21); no change (NC), 33% (7/21); and progressive disease (PD), 24% (5/21). Response rates in the control group were: NC, 20% (4/20); and PD, 80% (16/20). Increased pain was observed in one patient in the treated group and in 11 patients in the control group within the first 2 months. WHO grade III/IV toxicity in the chemotherapy group was as follows: nausea/vomiting 40%, diarrhoea 10%, stomatitis 15%, leucopenia 50% and thrombocytopenia 10%. One possible treatment-related death was due to sepsis. The median time to progression in the FEMTX group was 5.4 months [95% confidence interval (CI) 3.1-11.7 months], but only 1.7 months in the control group (95% CI 1.2-2.7 months) (P = 0.0013). Similarly, the FEMTX group displayed significantly (P = 0.0006) prolonged survival compared with the control group, i.e. median survival 12.3 months (95% CI 7.1-15.6 months) vs 3.1 months (95% CI 1.6-4.6 months). In conclusion, FEMTX combined with vitamin A and E is a fairly well-tolerated treatment, giving a response rate of 29% in patients with advanced gastric cancer, and also prolonging patients' survival. It can be used as a reference treatment in testing new investigational combinations.

Sequential MTX/5-FU therapy was performed on 64 patients with unresectable or recurrent gastric cancer. The therapy was most effective in patients with poorly differentiated type gastric cancer. We adopted the intermediate (MTX: 100mg/m2, 5-FU: 800mg/m2) and low (MTX: 30mg/m2, 5-FU: 600 mg/m2) dose regimens. The latter was performed at the outpatient clinic every 2 weeks. This therapy was used for patients with Borrmann type 4 gastric cancer or advanced gastric cancer of poorly differentiated type as postoperative adjuvant chemotherapy. The response rate was 25% in 44 evaluable patients, and 33% in patients with poorly differentiated type cancer. As an adverse effect, leukopenia (grade 3, 4) was observed in 4 patients (9%). The 5-year cumulative survival rate of the sequential MTX/5-FU therapy group (52.6%) was much better than the conventional adjuvant chemotherapy group (32.1%) in patients who underwent curative resection with Borrmann type 4 gastric cancer. One patient survived more than 900 days after non-curative resection with peritoneal dissemination (P 3) after low dose therapy of sequential MTX/5-FU. For the patients who did not respond to the MTX/5-FU therapy, MTX/CDDP/LV/5-FU therapy was adopted. This protocol consisted of MTX (30 mg/m2 iv; day 1), CDDP (60 mg/m2 div; day 2 and day 9), Leucovorin (30 mg iv; day 2-9) and 5-FU (250 mg/m2 div; day 2-9). We also performed MTX/CDDP/LV/5-FU therapy for the treatment of differentiated type gastric cancer.

We reported a case of gastric cancer with peritoneal dissemination, which was successfully treated by neoadjuvant chemotherapy and partial gastrectomy. A 71-year-old female visited to our hospital because of umbilical tumor (Sister Mary Joseph's node). UGI series showed a Borrmann 1 type gastric cancer and laparoscopic examination revealed peritoneal metastasis. Her abdominal cavity was treated with MTX and CDDP and she was given intravenous administration of 5-FU/LV. Repeated laparoscopy revealed complete disappearance of peritoneal seeding, and a partial gastrectomy was done. The histopathological findings of resected specimen showed the significant effects of preoperative chemotherapy. She has been living for more than 2 years with no recurrence after initial chemotherapy.

A 75-year-old man with gastric cancer having multiple liver metastases was given intraarterial infusion therapy with sequential low-dose MTX (30 mg/body) and 5-FU (1,000 mg/body) for metastatic liver tumors one month after the primary gastric tumor was resected. This therapy was given once a week on admission and every two weeks while an outpatient. A total of 18 courses of this therapy produced marked regression and necrosis of liver metastases. The effect was thus rated as partial response. This patient survived 15 months after surgery. These results indicate that intraarterial infusion therapy with sequential low-dose MTX and 5-FU may be effective in multiple liver metastasis from gastric cancer.

Cancer chemotherapy plays a central role in the treatment of recurrent or unresectable scirrhous gastric cancers classified mainly as Borrmann type 4. Though we have no specifically effective drugs for scirrhous gastric cancer, 5-FU and its derivative, MMC, anthracyclines, CDDP, CQ and ACNU are known to be relatively effective single agents against this tumor. In an attempt to enhance the effect of single agents, several combined chemotherapy regimens have been devised and tested. These regimens included 5-FU + MMC, UFT + MMC, UFT + CDDP, MTX.5-FU, FAM, FAP, EAP and ELF regimen. At present, combined therapies using 5-FU and MTX or CDDP may be the most attractive of these combined regimens.

A 70-year-old-male was diagnosed as having gastric cancer (Borr. 2, 78 mm in size on the body region; mod. dif. adenocarcinoma). CT scan revealed direct invasion of the liver. A course of MTX/5-FU sequential therapy was started (MTX 100 mg/m2, 5-FU 500 mg/m2, i.v., weekly; interval, 2 hours) on March 23, 1992. The gastric tumor showed 67% reduction on week 8 and 86% on week 10. The liver invasion had almost disappeared by CT scan (total doses, MTX 1,040 mg, 5-FU 6,750 mg). On June 25, the tumor was completely resected by radical.gastrectomy. The pathological specimen showed a "submucosal carcinoma" (10 mm in size, Stage I). Twenty-two months after the operation, the patient is alive and in good health. No cancer recurrence has been found without post-operative chemotherapy.
