[Enhancing effect by anti-cancer drugs on growth inhibition of colon carcinoma in nude mice by monoclonal antibody and complement].
We investigated the possible sero-therapeutic application of monoclonal antibody-A7 against human colorectal cancer. In complement dependent cytotoxicity, A7 showed 59% cytotoxicity against SW1116 cells. In addition, the killing of tumor cells by A7 and C was enhanced when the tumor cells were pretreated with 2 micrograms/ml mitomycin and 40 micrograms/ml adriamycin. Next, we evaluated the in vivo antitumor effect of A7 alone and combined with MMC on human colon cancer (Colon-6) bearing nude mice. The group injected with A7 alone showed definite antitumor effect compared with the non-treated group. The A7+MMC group (MMC: 4mg/kg, A7: 1 mg/body, two times) showed enhanced antitumor effect compared with the groups administered A7 alone or MMC alone.
