title: Phase I clinical trial of intralesional or intraventricular leukocyte interferon for intracranial malignancies.
abstract: Eight patients were treated with leukocyte interferon for a variety of neurological malignancies that had failed or recurred after conventional therapy. Three patients with malignant astrocytoma received intratumoral interferon in dosages up to 9 million units 3X/week, with total dosages of up to 160 million units. Interferon was administered intraventricularly in 4 patients with leptomeningeal metastases and one patient with multiple brain metastases. Dosages increased from 1 to 10 million units 3X/week, and total dosages of up to 113 million units were given intraventricularly. Acute side effects of fever, nausea, vomiting, and headache occurred almost exclusively with intraventricular injections, and these subsided after the initial injection. Fatigue, loss of appetite, weight loss, and hematologic toxicity developed a few weeks after onset of treatment, independent of the dose given. A modest tumor regression was seen on CT scans of one patient with a malignant astrocytoma, who was treated with interferon for 8 months. In all 4 patients with leptomeningeal metastases, the CSF became free of malignant cells for 6 to 10 weeks, while clinical improvement was less dramatic.
