    Notes: Summary This report presents the case of a 74-year-old woman who was simultaneously affected by two highly malignant neoplasms, a metastasizing renal cell carcinoma and a glioblastoma with sarcomatous component. Leptomeningeal metastasis of renal carcinoma is shown to invade the glioblastoma at its margin. Especially in gliomas, “cancer to cancer” phenomenoma are only rarely documented. Support by immunohistochemical data may prove those events to be more frequent than assumed.

    Notes: 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.
