Postoperative long term cancer chemotherapy (PLCC) with the combination of Mitomycin-C, FT-207, a furanyl analog of 5-fluorouracil, and PSK, an immunopotentiator, was prescribed for patients with advanced gastric cancer. Five year survival rates for all stage III and stage IV patients were 52.8 and 19.3 per cent in the PLCC group. The rates were 26.7 and 2.2 per cent in the control groups (p less than 0.05). In curative cases of stage IV, the 5-year survival rate was 50.0% in the PLCC group while the rate was 11.1% in the controls. Mean survival time of patients with peritoneal dissemination or hepatic metastases was 12.8 and 10.9 months, respectively, for the PLCC group, in contrast to the lower 6.4 and 4.3 months for the controls. Thus, the 5-year survival rate of advanced gastric cancer patients in stage III and stage IV was markedly improved when these patients were treated with the protocol. Our findings clearly show that adjuvant chemotherapy should be administered for a long period postoperatively in order to achieve a significant improvement in patients with gastric cancer.

Hemolytic uremic syndrome spontaneously arises in a few patients with advanced cancer, but it is more commonly related to the use of certain chemotherapeutic agents. Mitomycin-C is, etiologically, the most common causative agent inducing hemolytic uremic syndrome, in a dose dependent manner. We report this syndrome, attributable to mitomycin-C at a cumulative dose of 40 mg/m2, in a gastric cancer patient. A 42-year-old female with stage III gastric cancer underwent radical gastrectomy and was given mitomycin-C at 10 mg/m2 intravenously every four weeks as adjuvant therapy. Hemolytic uremic syndrome was diagnosed three months after the last dose of mitomycin-C administration. The most prominent symptoms included pallor, hypertension and anasarca, with laboratory evidence of microangiopathic hemolytic anemia, azotemia and hyperkalemia. Her disease was progressive, but fortunately stabilized after staphylococcus column A dialysis. Her disease remained in remission for 24 months from the time of diagnosis, and then relapsed in the form of peritoneal carcinomatosis with partial intestinal obstruction.

We have reported a successful case of curative partial liver resection of metachronous liver metastasis from advanced gastric cancer. The patient was 56 years old and has undergone total gastrectomy with D2 lymph node dissection (2 type, well-differentiated adenocarcinoma, H0P0n0se, Stage 2). At 18 months later, follow-up ultrasound detected liver metastasis in the right posterior segment. Together with other imaging modalities, it was diagnosed as a solitary lesion without any other recurrence, and we performed partial resection of the right posterior segment. During the operation, there was no sign of any other recurrence (no peritoneal dissemination, no lymph node metastasis, and no other liver metastasis). Two Mitomycin-C (MMC) intravenous injections were given as postoperative chemotherapy. Usually, surgery for liver metastasis from gastric cancer is very rare as a curative therapy, because it is difficult to predict the effectiveness of the operation. In the present case, we decided on the operation since there was no sign of any other recurrence. It has now been 13 years to date since the partial liver resection and the patient remains free from recurrence.

Alpha-fetoprotein (AFP) expression is observed in embryonic tissues and, the expression of this protein is absent in normal adult tissues. The re-elevation of serum AFP strongly suggests generation of a malignant tumor in an adult. We demonstrated here that AFP-producing gastric cancer (AFP-gastric cancer) could be treated by a combination therapy with a low dose of Mitomycin-C (MMC) and lymphokineactivated killer T (LAK-T) cells. Treatment with MMC of AFP-gastric cancer cells enhanced their susceptibility to LAK-T cells and induced ATBF1 gene expression. We revealed here a novel signal pathway for regulation of the cell cycle of AFP-gastric cancer cells through ATBF1, which enhances the promoter activity of the p21 (Waf1/Cip1) gene. Immunoprecipitation revealed the direct interaction between ATBF1 and p53. Overexpressed ATBF1 stimulated p21 (Waf1/Cip1) promoter activity up to 4-fold compared with basal activity. The expression level of ATBF1 mRNA was doubled by MMC (0.05 microg/ml) treatment. The MMC treatment and ATBF1 overexpression synergistically activated the p21 (Waf1/Cip1) promoter activity in a dose-dependent manner up to 7-fold compared with basal activity.
