An anti-cancer drug sensitivity test was performed using a transplantable human osteosarcoma originated in the mandible (HOSIVIN-1). The drugs tested in this study were Adriamycin (ADM), Cis-platinum (CDDP), and Methotrexate (MTX)(high and low-dose). The effect of the drugs were judged according to the Battelle Columbus Laboratories Protocol (BCLP), and the following results were obtained.<BR>1) Growth inhibition was seen with all drugs.<BR>2) With respect to the duration of effect and the maximum rate of tumor inhibition, the most effective drug was losv-dose MTX followed by CDDP, high-dose MTX and ADM in that order.<BR>3) In the substantial weight change, only low-dose MTX group showed no weight loss. Refering to its low incidence of side effect as well, it was suggested that low-dose MIX was most useful in this experiment.
