To prevent dissemination to the peritoneum following surgery for gastric cancer, examinations were performed with mouse ascites cancer models and the objective of enhancing the combined effect of MMC, CDDP and 5-FU. Pharmaceutical dosage was set at approximately 30% of the increased life span (ILS) for Meth-A. The dosage was 0.2 mg/kg for MMC, 1 mg/kg for CDDP and 37.5 mg/kg for 5-FU. Results indicated that simultaneous combination of 0.2 mg/kg of MMC and 1 mg/kg of CDDP extended life significantly more than individual administration, and clinical application of this combination was considered to be possible. In contrast, simultaneous combination of 1 mg/kg of CDDP and 37.5 mg/kg of 5-FU had no clear life-extending effect compared to individual administration of each. Some biochemical modulation of the administration method was thus considered necessary.

Based on the experimental studies using Meth A and L 1210 transplantable mouse, which indicated that simultaneous combined administration of MMC and CDDP prolonged life span more significantly than individual administration, clinical application was performed on 14 cases with carcinomatous peritonitis in gastric cancer. One hundred mg of CDDP was administered before the closure of abdomen and drainage tubes were opened 2 hours later. Then, repeated administration of 10 mg/body of MMC and 40-50 mg/body of CDDP was continued once a month via the drug delivery system. Negative change of cytology was observed in seven out of 14 cases, and the prognosis of these patients was better than in the unchanged cytology group. Side effects such as severe gastro-intestinal symptoms and bone marrow toxicities were not recognized. Further studies should be done to confirm the efficacy of the intraperitoneal chemotherapy for carcinomatous peritonitis.

A new indolocarbazole compound, ED-110, which was obtained by glucosylating a microbial product (BE-13793C) and is a potent topoisomerase I inhibitor, showed characteristic inhibitory effects on the growth of 12 human tumor cell lines tested. The IC50 values of ED-110 against 9 of the 12 lines ranged from 11.5 micrograms/ml to 0.07 microgram/ml, while the remaining 3 lines were quite resistant (IC50, > 100 micrograms/ml). In in vivo experiments, i.p. treatment with ED-110 increased the survival period by more than two-fold in mice implanted i.p. with P388, L1210, L5178Y or EL4 murine leukemic cells. The minimum effective dose increasing the life-span of mice bearing P388 leukemia by 25% was < 2.5 mg/kg/day x 10 and the maximum tolerated dose was > 160 mg/kg/day x 10. ED-110 was also effective against the spontaneous metastasis of mouse Meth A fibrosarcoma cells and the growth of xenografted MKN-45 human stomach cancer cells as well as s.c. implanted mouse colon 26 and IMC carcinoma cells. These results indicated that ED-110 may have potential as a new antineoplastic agent with a large chemotherapeutic index and a wide range of effective doses.

Although AIMP1 (previously known as p43) is one of three auxiliary proteins bound to a macromolecular aminoacyl tRNA complex, it is also secreted as a cytokine controlling both angiogenesis and immune responses. Here we show that systemically administered purified recombinant human AIMP1 had anti-tumor activity in mouse xenograft models. In Meth A-bearing Balb/c mice, tumor volume increased about 28 fold in the vehicle treatment group, while an increase of about 16.7 fold was observed in the AIMP1-treated group. We also evaluated the anti-tumor activity of AIMP1 in combination with a sub-clinical dose of the cytotoxic anti-tumor drug, paclitaxel. The growth of NUGC-3 human stomach cancer cells was suppressed by 84% and 94% by the combinations of 5 mg/kg paclitaxel + 25 mg/kg AIMP1 (p = 0.03), and 5 mg/kg paclitaxel + 50 mg/kg AIMP1 (p = 0.02), respectively, while 5 mg/kg paclitaxel alone suppressed growth by only 54% (p = 0.02). A similar cooperative effect of AIMP1 and paclitaxel was observed in a lung cancer xenograft model. These results suggest that AIMP1 may be useful as a novel anti-tumor agent.
