The purpose of this study was to determine the relationship between platinum-DNA adducts in leukemic cells and the success of remission induction therapy in adult patients with acute nonlymphocytic leukemia (ANLL). Freshly isolated cells from pre-treatment bone marrow aspirates of 14 patients were incubated with cisplatin in vitro and the amount of platinum bound to DNA was determined using a competitive ELISA procedure and an antibody directed against platinum-modified DNA. Platinum-DNA adduct levels discriminated well between complete remission (CR) and remission failure (RF) patients, treated with mitoxantrone, cytosine arabinoside +/- carboplatin.
