title: Intratumoral administration of tumor necrosis factor-alpha for malignant gliomas--two case reports.
abstract: Two patients with histologically verified glioblastoma multiforme and anaplastic astrocytoma were treated with four courses of intratumoral administration of human natural tumor necrosis factor-alpha (TNF) (specific activity 2.0 x 10(6) Japan reference unit [JRU]/mg protein) at intervals of 3-5 months. Each consisted of eight to 10 serial injections, ranging from 5 x 10(3) to 10(4) JRU/injection, at intervals of 3-5 days. There was no simultaneous administration of steroids. Serial neurological examinations and neuroimaging studies with computed tomography and magnetic resonance imaging demonstrated partial responses ranging from 28 and 36 months in duration. No significant TNF-related brain edema, intracerebral bleeding, or neurotoxicity occurred. Local immunotherapy with TNF may be used safely to contribute to therapeutic efficacy.
