title: Combination chemotherapy of L1210 leukemia with platinum compounds and cyclophosphamide plus other selected antineoplastic agents.
abstract: Six antitumor platinum compounds were used in combination with cyclophosphamide plut 1 of 7 other antitumor drugs for treatment of L1210 leukemia in B6D2F [C57BL/6 X DMA/2) F] mice. Data obtained from each three-agent regimen were compared with those obtained after administration of each compound alone and each appropriate two-agent combination. No cure (greater than 60-day survival) was obtained with any compound used alone. Combination of cyclophosphamide with a platinum compound (Pt+CY) yielded a collective cure rate of 193/420, and the addition of a third cure rate to 290/420 (P less than 0.001). Certain regimens produced 100% cure rates. The most effective drugs when used in combination with PT+CY were cytosine arabinoside, 5-fluorouracil, hydroxyurea, and Yoshi-864. Adriamycin, methotrexate, and vincristine were less effective at the doses used. Toxicity, as evidenced by maximum weight loss, was slightly greater with the three-agent combinations than with the Pt+CY regimens.
