Abstract
In this study mitoxantrone (Mtx) induced DNA strand breaks were measured with the alkaline elution technique in short term cell cultures derived from human gliomas. Glioblastomas or astrocytomasfrom 5 patients who underwent intracranial surgery were cultured and incubated 1 h with different concentrations of Mtx (0, 0.01, 0.1 and 1.0 μg/ml). The alkaline elution methodwas modified to measure DNA lesions in human gliomas. Mtx inducedDNA strand breaks in a dose dependent manner in all cell culturestested. There was a linear increase of DNA strand break frequencyinduced by Mtx between 0.01—1.0 μg/ml. Concerning these in vitro data, Mtx might be potentially useful for the treatment ofpatients with malignant brain tumors.
