Fifteen patients, 12 with glioblastoma multiforme and 3 with anaplastic astrocytoma, were treated with "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 3,000 mg/m2, cisplatin 90 mg/m2, cytosine arabinoside 300 mg/m2, and imidazole carboxamide 150 mg/m2]. All patients had prior brain irradiation but none had previous chemotherapy. The population included 10 patients with progressive disease after irradiation and 5 who presented within 2 months of completing radiation. Patients received an average of 5 monthly cycles of chemotherapy. Three patients achieved a complete and 2 a partial response (CR + PRrate was 33%). The median survival time was 46 weeks. Myelosuppression was the dose-limiting toxicity. Leucocyte counts between 2.0-4.5 x 10(3)/mm3 were observed in 40% of patients, between 1.0- less than 2.0 x 10(3)/mm3 in 33%, and less than 1.0 x 10(3)/mm3 in 7%. Platelet counts between 50-130 x 10(3)/mm3 were observed in 27% of patients, and less than 50 x 10(3)/mm3 in 33%. Six patients suffered infections, 4 had reversible renal toxicity, 2 developed paresthesias, and one a debilitating myopathy related to treatment with dexamethasone. Ototoxicity was seen in 3 patients. Two patients developed pulmonary emboli. Nine patients had nausea and vomiting, in one case associated with Candida esophagitis. One long-term survivor developed necrosis of the corpus callosum and dementia. Four patients discontinued treatment after an average of 3.5 cycles because of toxicity. Although extremely toxic, this regimen has modest activity in previously irradiated adult patients with malignant glioma.

Radiotherapy is a standard postoperative treatment for cerebral glioma. We have observed the onset of symptoms related to brain necrosis, as opposed to recurrent tumor, in surviving patients. This has been manifest as dementia with a computed tomographic pattern of low density in the frontal lobe uninvolved with tumor, but within the field of radiotherapy. Two patients presented with mass lesions also unrelated to recurrent tumor. We question the necessity of full brain irradiation and suggest that radiotherapy techniques be altered to target the tumor and not encompass the entire brain.

Normal pressure hydrocephalus is frequently emphasised as a cause of reversible dementia, but is seldom encountered. Over a 2 year period, 5 patients presented with cognitive decline, and gait disturbance, with or without incontinence. CT head examination revealed hydrocephalus. Although none had symptoms of raised intracranial pressure on initial presentation, there were clinical or CT signs of raised intracranial pressure in 4 of the 5. Underlying pathologies were meningeal lymphocytic lymphoma, idiopathic meningeal fibrosis, periaqueductal glioma, basilar aneurysm and basilar invagination. All patients responded to the insertion of a shunt. Over the same period, only 1 patient was shunted for idiopathic normal pressure hydrocephalus, without improvement. We challenge the concept of idiopathic normal pressure hydrocephalus as a cause of cognitive deterioration.

Six cases of symptomatic parasellar granular cell tumor (pituicytoma, myoblastoma, choristoma) are reported. The clinical presentations included visual loss, dementia, and adenohypophyseal insufficiency. Lack of calcification and a suprasellar blush on angiography often help to differentiate these lesions from craniopharyngioma, pituitary adenoma, and optic glioma. These are the first cases studied by computed tomographic scan, which shows a high density, sharply demarcated lesion in the suprasellar region with dense, frequently homogeneous contrast enhancement. At operation these are characteristically tough, nonsuckable, vascular tumors. All previously reported patients with long survival (seven cases) have been contacted recently. The data do not support a role for postoperative radiation therapy. The surgical goal should be limited to decompression of the suprasellar if total excision seems too hazardous.

We report a patient with selective short-term memory disturbance caused by a glioma in the left temporal-parietal lobe. The patient was a 40-year-old right-handed housewife who complained of difficulty in memorizing series of numbers. She was working as a car dealer. She was well until 6 months prior to the present admission when she noted a difficulty in memorizing series of numbers such when telephone numbers and car registration numbers. She had to write them down as her customers told them to her. On admission, she was alert and oriented to all spheres. She was mentally sound without dementia. She did not show aphasia, apraxia, or agnosia, except for brief periods of seizures in which she became unable to speech. Neuropsychological examination revealed that she had difficulty in repeating and dictating series of numbers and meaningless kana words. However, she could easily pick up the correct series of numbers or kana words among multiple choices presented visually. Thus it was clear that her problem was not the disturbance of auditory input nor expression, but a selective impairment of short-term memory. She could memorize the same stimuli when visually presented. Therefore, her problem was thought to be a disturbance of auditory short-term memory of meaningless words. After resection of her tumor, she developed transient amnesic aphasia, which improved a year later. She was examined again in her memory function. In the task of visual stimuli, we presented her a card in which a series of numbers or a nonsense syllable was written for 5 seconds and asked her to remember them.(ABSTRACT TRUNCATED AT 250 WORDS)

Analysis of 139 CSF samples from living subjects, using iso-electric focusing in polyacrylamide gels, demonstrated an anomalous molecular form of acetylcholinesterase (AChE). This form was present in 84 of 87 patients with a clinical diagnosis of Alzheimer's disease (AD), 28 of whom have died and in whom histopathological confirmation of AD was obtained. The abnormal AChE form was also present in 22 of 23 patients with clinical dementia not regarded as AD type. In the six patients who died this abnormal AChE form was found in three cases of multi-infarct dementia, one with cerebral glioma with dementia and one with clinical dementia, but no pathology was found based on the Khachaturian criteria for AD. One patient with normal pressure hydrocephalus was negative when tested for the abnormal AChE form. This evidence indicates that the anomalous molecular form of AChE may not be specific for AD, and may possibly be a common indicator for organic dementia. The discovery of this form in 27 of 29 age-matched non-demented controls may indicate that the anomalous molecular form of AChE may not only exist in patients with clinically detectable dementia, but is probably present for a period before the onset of dementia. Recognizing and understanding the existence of pre-clinical dementia would be beneficial in designing a strategy for both the prevention and the treatment of dementia.

The authors report a case of neuronal ceroid lipofuscinosis (Kufs' disease) confirmed by stereotactically obtained brain biopsy findings and initially diagnosed as a butterfly glioma. The presenting symptoms in the 64-year-old patient were mental alterations with progressive dementia, followed by muscular atrophy and myoclonia with distal preponderance. The mild initial disturbances of coordination increased, and the patient developed a markedly ataxic gait. Computerized tomography (CT) scanning and magnetic resonance imaging revealed generalized cerebral atrophy and a bifrontal space-occupying lesion involving the callosum. The original "clearcut" diagnosis of glioblastoma multiforme, based on CT scans, was unexpectedly disproved by examination of stereotactically obtained brain biopsy specimens, which revealed a neuronal ceroid lipofuscinosis (Kufs' disease). To the authors' knowledge, this is the first report of a case presenting with both diffuse brain atrophy and localized accumulation of neuronal lipofuscin, mimicking a mass lesion on radiological studies.

Aluminum, a trivalent cation unable to undergo redox reactions, has been linked to many diseases such as dialysis dementia and microcytic anemia without iron deficiency. It has also been implicated in Alzheimer's disease although this is controversial. Because cell death due to oxidative injury is suspected to be a contributory factor in many neurological diseases and aluminum neurotoxicity, glioma (C-6) and neuroblastoma (NBP2) cells were utilized to assess early changes in oxidative parameters consequent to a 48-h exposure to aluminum sulfate. A 500-microM concentration of this salt produced a significant increase in reactive oxygen species (ROS) production and a significant decrease in glutathione (GSH) content in glioma cells. However, the same concentration of the aluminum salt did not lead to any significant changes in the neuroblastoma cells. Mitochondrial respiratory activity in glioma cells was also found to be significantly higher in the aluminum treated cells. As judged by morin-metal complex formation, aluminum can enter glioma cells much more readily than neuroblastoma cells. Thus, it is possible that the cerebral target following an acute exposure to aluminum may be glial rather than neuronal.

The benefit of standard treatment of malignant glioma in older patients is debated. In order to assess the effect of a combination of surgery, radiotherapy and chemotherapy on survival of elderly patients with high grade gliomas, 30 consecutive patients older than 70 years with malignant supratentorial gliomas were studied between 9/93 and 9/96. Median age was 73 years (70-79). The mean Karnofsky performance status (KPS) was 66 (30-100). Patients underwent maximum possible surgery, followed by a course of radiotherapy (45 Gy/25 fractions/5 weeks) with 3 or 4 orthogonal beams and a 2 cm margin around the tumor bed. The administration of chemotherapy was left at the discretion of the responsible physician and 12 patients received reduced dose nitrosourea-based chemotherapy. The overall median survival was 36 weeks. The median time to progression was 26 weeks. Three months after surgery, 26 patients were alive, 5 were in complete response, 2 in partial response and 10 were stabilized. Preradiotherapy KPS was the only significant prognostic factor with a median survival of 40 weeks in patients with KPS > or = 70 and 25 weeks when KPS was < 70 (logrank test, p = 0.05). In responding and stable patients (57% of the group) the median KPS was 68 and 66 at 1 and 3 months after the completion of radiotherapy. There was no case of radiotherapy-induced dementia with this regimen. Four out of 12 patients who received chemotherapy, experienced WHO grade 3/4 hematotoxicity. This study suggest that some patients older than 70 years with KPS > or = 70 may benefit from the treatment of malignant gliomas with surgery followed by reduced dose of limited field radiotherapy. Further studies are needed to define the most appropriate dose of radiotherapy and to evaluate further the risk/benefit ratio of a reduced dose chemotherapy in this population.
