Neocarzinostatin (NCS) is an antibiotic from streptomyces carzinostaticus which inhibits DNA synthesis. Clinical trials in Japan began in 1971. NCS is active against S-180, Ehrlich tumor, L1210, Yoshida sarcoma, and a range of ascitic hepatomas. In rabbit NCS is distributed at high concentrations in the kidney, skin, stomach, pancreas, lung, and muscles. The high distribution in the pancreas and the stomach suggested possible effectiveness in human tumors at these sites. In clinical studies NCS has been shown to be active against acute leukemia. As a single agent 9 out of 51 obtained a CR with 9 more achieving a PR. Anorexia, nausea, and vomiting were the most frequent side effects. NCS has been tried in combination with Ara-C, daunorubicin and prednisolone and CR was ssen in 11 out of 14. In stomach cancer responses of some kind were observed in 12 out of 141 cases, while in the case of pancreatic tumors there were 10 out of 68.

As a postoperative adjuvant chemotherapy for gastric cancer, we have administered a combination of NCS (Neocarzinostatin) and 5-FU (NF treatment method) and in this paper we have compiled the results obtained in patients who were treated for 5 years in an attempt to compare the 5-year survival rate with that of patients administered a combination of MMC and 5-FU (MF treatment group) and a control group administered no anticancer agents. As the selection of either NF or MF treatment was conducted on an annual basis, this study can be considered an historical controlled study. The results obtained are summarized as follows. On comparing the survival rate of the NF treatment group and the control group, the 5-year survival rate for all patients who underwent curative resection and all patients with histological stage III cancers and the curative resection PS (+) group, as well as the survival period of the non-resected patients, showed a statistically significant difference, indicating that the survival rate was higher in the NF group. On comparing the NF group and the MF group, although no statistically significant difference was observed between then based on a stratified analysis of all resected cases, histological stage differences and n.ps factors, etc., certain values tended to indicate a higher survival rate for the NF group. Moreover, the survival rate of the non-resected patients was more favorable in the NF group. These results confirm that NCS is useful for the treatment of stomach cancer and compares favorably with MMC. The appearance of side-effects was significantly lower in the NF group in comparison with the MF group and the number of patients who had to discontinue therapy was extremely low.

The significance and effectiveness of adjuvant intraoperative chemotherapy using subserosal or submucosal administration of Neocarzinostatin (NCS) and CH 40 for gastric cancer and colorectal cancer were studied. Tissue NCS concentration of proximal lymph nodes were higher than for distant lymph nodes, while the immunocompetency of distant lymph nodes (lower NCS concentration) showed slightly higher activity than that of proximal lymph nodes. From these results, it is suggested that loco-regional administration of NCS might be effective for chemical lymph node cleaning of the cancer.
