title: Murine neuroblastoma: further evaluation of the C1300 model with single antitumor agents.
abstract: The murine C1300 neuroblastoma model has been evaluated as a possible model for children with widespread metastatic disease. Drug toxicity studies were conducted in adult A/J mice with various doses of antitumor agents. Adriamycin, BCNU, bleomycin, guanazole, acronycine, isophosphamide, DTIC, ICRF-159, cyclophosphamide, vincristine, and vinblastine were adminstered intraperitoneally to random groups of normal mice. After identification of appropriate doses, chemotherapy studies were conducted with varius regimens of drugs. Chemotherapy was administered to adult A/J mice when their subcutaneously implanted tumors measured 1.0-1.7 cm in diameter. Antitumor drugs can be classified into three groups according to drug efficacy. BCNU, cyclophosphamide, and isophosphamide were extremely active. Cytosine arabinoside was reported to be active against this murine tumor in a previous publication. Drugs with minimal activiyt which deserve further evaluation included adriamycin, guanazole, ICRF-159, DTIC, and vinblastine. Inactive drugs were acronycine, bleomycin, 5-fluorouracil, and vincristine. These experiments suggest that children with metastatic neuroblastoma may respond to cyclophosphamide, isophosphamide, and BCNU, while DTIC, adriamycin, ICRF-159, guanazole, and the vinca alkaloids may also be effective. The results suggest that agents selected by the C1300 model should be given adequate clinical trials.
