To target the treatment of small points of cancer, Beriplast P, already used clinically as a physiological tissue adherent drug carrier, was mixed with the anticancer drug, mitomycin C (MMC). In this in vitro study, MMC did not release quickly from the clot of MMC/Beriplast P. The antitumor effect of this mixture was examined for its effect on cancer growth. In one series of experiments, tumor tissues were inoculated with MMC/100 μl Beriplast P and in another series, MMC/100 μl Beriplast P was injected into tumors at a weight of 300 mg. In the first series of experiments, tumor tissue treated with 0.3 mg MMC/100 μl Beriplast P was replaced with plasma cells and lymphocytes, and no viable cancer cells could be found. In the second series, MMC/100 μl Beriplast P delayed tumor growth, and the survival of Balb/c mice injected with 0.08 mg MMC/100 μl Beriplast P was significantly longer than that of mice injected with 0.08 mg MMC/100 μl saline solution ( P=0.026). In addition, the abdominal aorta, vena cava, and intestine around the area of treatment with 1.6 mg MMC/100 μl Beriplast P were not damaged. These results indicate that the mixture of Beriplast P and MMC is more effective than MMC solution alone in the local treatment of residual cancer. [ABSTRACT FROM AUTHOR] |
