Thirty-one adult patients with malignant glioma (23 with glioblastoma multiforme, six with anaplastic astrocytoma, and two with brainstem glioma) were treated with up to ten cycles of "eight-drugs-in-one-day" chemotherapy (methylprednisolone 300 mg/m2, vincristine 1.5 mg/m2 [maximum of 2 mg/cycle], CCNU 75 mg/m2, procarbazine 75 mg/m2, hydroxyurea 3000 mg/m2, cisplatin 90 mg/m2, cytosine arabinoside 300 mg/m2, and imidazole carboxamide 150 mg/m2). Chemotherapy was planned as two cycles before and eight cycles after 60 Gy of involved brain irradiation. A total of 117 cycles of chemotherapy was administered. There was one treatment-related death. Myelosuppression was the most frequent toxic effect (leucopenia was less than 1000/mm3 in 9% of cycles and 1000-2500/mm3 in 25%; thrombocytopenia was less than 100,000/mm3 in 33% of cycles). Sixteen patients developed infections requiring treatment, two of which were life-threatening. Five patients suffered ototoxicity. Nausea and vomiting were observed in 35% of patients. A reversible rise in creatinine was observed in five patients. One patient developed a severe motor neuropathy, and three patients developed mild peripheral neuropathies. Three patients had episodes of atrial fibrillation. One new bundle branch block with supraventricular tachycardia was observed in a patient with pulmonary embolus. Five patients developed thrombophlebitis, three of whom had pulmonary emboli. Two patients suffered strokes in areas anatomically separate from their tumor. Eleven patients declined to continue therapy after receiving an average of three cycles. Two had complete, and five had partial responses. The median survival time was 47 weeks. The responses and survival times observed are comparable to less toxic treatment protocols for adults with malignant gliomas.

A 55 year-old woman was admitted to hospital in January 1981 with transient expressive dysphasia. Past personal history was unremarkable except for a six-month history of renal colic and thrombophlebitis in the veins of the right leg. Computed tomographic scan of the head and carotid angiogram revealed a left calcified temporoparietal tumor. Because of pulmonary embolism it was decided to refute a cerebral biopsy. The patient also declined radiotherapy. In May 1983, a thorough workup revealed an incomplete fracture of the first lumbar vertebra and a diffuse demineralization of the rachis and pelvis. Four weeks later she developed temporal epilepsy and pulmonary embolism. A whole brain irradiation (60 Gy) was performed in August 1983. The patient's condition remained clinically stable until December 1984 when she was readmitted to hospital with a severe weight loss, diffuse osseous pain and pancytopenia. A bone marrow biopsy from the iliac crest showed a diffuse tumor involvement. Peroxidase-antiperoxidase staining using monoclonal antiserum to glial fibrillary acidic protein was strongly positive in numerous tumors cells. The pathological diagnosis was bone marrow metastasis by glioma. She died in March 1985, 4 years and 3 months after the first admission to hospital. Autopsy was not performed. A literature search reveals only 9 cases of extraneural spreading of astrocytomas and glioblastomas in the absence of previous craniotomy with post-mortem examination. The authors also comment on the clinical, pathological and histogenic aspects of extraneural metastasis of gliomas.

Twenty-two patients with supratentorial malignant gliomas were treated postoperatively with concurrent intracarotid chemotherapy and radiation therapy. There were seven women and 15 men with a median age of 56 years (range, 22-69) and median performance status (Karnofsky score) of 70 (range, 40-90). In all except two cases, histologic studies confirmed malignant glioma. All patients were irradiated with a cobalt 60 equipment. They should have received 45 Gy to the whole brain plus a 15-Gy coned-down boost to the tumor area. Chemotherapy consisted of cisplatin infusion at a dose of 60 mg/m2 on days 2, 22, and 42. Treatment was interrupted in two patients because of progressive disease and voluntary withdrawal in one patient each. In all, 63 courses of cisplatin infusion were administered, all at full dose. Two patients achieved a partial response, and nine had stable disease. Toxicities included nausea/vomiting in nine patients (41%) and transient hemiparesis, confusion, diarrhea, and thrombophlebitis in one patient each. Median time to progression was 26 weeks (range, 4-226+), and median survival was 58 weeks (range, 14-226+). In conclusion, the present study suggests that intracarotid cisplatin administered concurrently with radiation does not improve the therapeutic index in malignant gliomas.
