Abstract
Lifetime job histories from a population-based, case-control study of gliomas diagnosed among adults in the San Francisco Bay area between August 1991 and April 1994 were evaluated to assess occupational risk factors. Occupational data for 476 cases and 462 controls were analyzed, with adjustment for age, gender, education, and race. Imprecise increased risks were observed for physicians and surgeons (odds ratio (OR) = 3.5, 95% confidence interval (CI): 0.7, 17.6), artists (OR = 1.9, 95% CI: 0.5, 6.5), foundry and smelter workers (OR = 2.6, 95% CI: 0.5, 13.1), petroleum and gas workers (OR = 4.9, 95% CI: 0.6, 42.2), and painters (OR = 1.6, 95% CI: 0.5, 4.9). Legal and social service workers, shippers, janitors, motor vehicle operators, and aircraft operators had increased odds ratios only with longer duration of employment. Physicians and surgeons, foundry and smelter workers, petroleum and gas workers, and painters showed increased risk for both astrocytic and nonastrocytic tumors. Artists and firemen had increased risk for astrocytic tumors only, while messengers, textile workers, aircraft operators, and vehicle manufacturing workers showed increased risk only for nonastrocytic tumors. Despite study limitations, including small numbers for many of the occupational groups, a high percentage of proxy respondents among cases, and lack of specific exposure information, associations were observed for several occupations previously reported to be at higher risk for brain tumors generally and gliomas specifically.

Abstract
Radio-induced tumor have been known for a long time to occur after treatment of cancer during childhood. This entity is exceptional following radiotherapy of the cavum. Skull and facial osteosarcoma were described after treatment of UCNT. We report two observations of radio-induced tumors arising, respectively three and seven years after treatment of UCNT. The first one is a temporoparietal glioblastoma and the second is a rhino- and pharyngeal myxoma. The two patients are alive after treatment of the second tumor. The delay of appearance of these tumors, their situation in the field's irradiated and dose received suggests their radio-induced nature. However, the cytogenetic study is necessary to confirm the implication of radiotherapy in the genesis of these cancers.

Abstract
To clarify factors that may contribute to the development of intratumoral hemorrhage, we analyzed the expression of tissue factor (TF), an initiator of the extrinsic coagulation pathway, and of tissue factor pathway inhibitor (TFPI) in glioblastomas with or without massive intratumoral hematoma. Among 196 glioma cases reviewed, there were 13 with macroscopic intratumoral hemorrhage. We focused on the glioblastomas and used immunoblot- and immunohistochemical methods to compare the expression of TF and TFPI in 9 glioblastomas with macroscopic hematoma and 30 glioblastomas without macroscopic hemorrhage. Although TF was expressed in most glioblastomas irrespective of the presence or absence of macroscopic hemorrhage, the staining patterns differed significantly: TF-positive glioma cells were diffusely present in the non-hemorrhage group; in the group with hemorrhage, positive cells, primarily macrophages, were scattered throughout the tissue examined. The expression of TFPI was significantly higher in the group with than in the group without hemorrhage. Our results suggest that local suppression of the TF-dependent coagulation cascade is a contributing factor that permits the occurrence of intratumoral hemorrhage.

Abstract
Cancer and its link to reproductive hormones is an area of intense concern for our patients and has been the subject of much speculation. But if estrogen causes breast cancer, for example, most women would eventually develop the disease. We know this is not the case! Actually, estrogen and progesterone have been linked to a decrease as well as an increase in cancer, depending upon the type of tumor under investigation. The purpose of this manuscript is to review the data supporting those relationships.

Abstract
We report a surgical case of a 54-year-old woman with a radiation induced glioblastoma. At the age of 34, the patient was diagnosed to have a non-functioning pituitary adenoma. It was partially removed followed by 50 Gy focal irradiation with a 5 x 5 cm lateral opposed field. Twenty years later, she suffered from rapidly increasing symptoms such as aphasia and right hemiparesis. MRI showed a large mass lesion in the left temporal lobe as well as small mass lesions in the brain stem and the right medial temporal lobe. These lesions situated within the irradiated field. Magnetic resonance spectroscopy revealed relatively high lactate signal and decreased N-acetyl aspartate, choline, creatine and phosphocreatine signals. Increased lactate signal meant anaerobic metabolism that suggested the existence of a rapidly growing malignant tumor. Thus, we planned surgical removal of the left temporal lesion with the diagnosis of a radiation induced malignant glioma. The histological examination revealed a glioblastoma with radiation necrosis. MIB-1 staining index was 65%. Postoperatively, her symptoms improved, but she died from pneumonia 1 month after the surgery. An autopsy was obtained. The lesion of the left temporal lobe was found to have continuity to the lesion in the midbrain, the pons and the right temporal lobe as well. High MIB-1 staining index suggested that a radiation induced glioblastoma had high proliferative potential comparing with a de novo and a secondary glioblastoma.

Abstract
Gliomas are the most common primary malignant brain tumours and are classified into four clinical grades, with the most aggressive tumours being grade 4 astrocytomas (also known as glioblastoma multiforme; GBM). Frequent genetic alterations in GBMs (refs 2-5) result in stimulation of common signal transduction pathways involving Ras, Akt and other proteins. It is not known which of these pathways, if any, are sufficient to induce GBM formation. Here we transfer, in a tissue-specific manner, genes encoding activated forms of Ras and Akt to astrocytes and neural progenitors in mice. We found that although neither activated Ras nor Akt alone is sufficient to induce GBM formation, the combination of activated Ras and Akt induces high-grade gliomas with the histological features of human GBMs. These tumours appear to arise after gene transfer to neural progenitors, but not after transfer to differentiated astrocytes. Increased activity of RAS is found in many human GBMs (ref. 11), and we show here that Akt activity is increased in most of these tumours, implying that combined activation of these two pathways accurately models the biology of this disease.

Abstract
Several types of epidermal growth factor receptor (EGFR) gene mutations have been reported in glioblastomas, and in nearly all cases the alterations have been reported in tumors with EGFR amplification. The objectives of this study were to determine the frequency and diversity of EGFR mutations in glioblastomas and to determine whether gene mutation is inevitably associated with increased EGFR gene dosage. To accomplish these aims, we sequenced cDNA products representing the entire EGFR coding region in 44 glioblastomas, half of which had EGFR amplification. Coding sequence alterations were identified in 17 of the tumors, and each of these cases had amplified EGFR. No mutations were identified in the 22 tumors without EGFR amplification. An additional 26 glioblastomas with EGFR amplification were then examined to establish more reliable frequencies for each type of mutation identified in the tumors for which the entire gene was sequenced. Transcripts associated with the most common mutation lacked coding sequence for amino acids 6-273 (67%). This mutation has been described extensively in the literature. Transcripts encoding receptors that would truncate at amino acid 958 and transcripts encoding receptors that would lack amino acids 521-603 were the next most common types of alteration. Each of these were observed in 15% of the tumors with EGFR amplification. Other mutations were observed at lower frequencies, but among these were three cases with missense mutations. Sixteen of the 48 tumors with EGFR amplification showed multiple types of EGFR mutations (33%), and in one case it was determined that multiple alterations had occurred in the same transcript. In total, these data are consistent with EGFR mutation being exclusively and frequently associated with EGFR amplification. Furthermore, the determination of multiple EGFR mutations within individual tumors suggests that glioblastomas with EGFR amplification have the capacity to produce a variety of functionally distinct EGFRs.

Abstract
The aneuploidy of autosomes 7, 10, and sex chromosomes (X and Y) was analyzed in a series of 44 primary (de novo) and 20 secondary glioblastomas using fluorescence in situ hybridization (FISH) on smear preparations of glioma tissue. The tumors were screened for trisomy 7, monosomy 10, as well as loss of the Y chromosome and disomy of the X chromosome in male subjects, and monosomy of the X chromosome in female subjects. We found that taken alone or in combination, these chromosomal abnormalities do not appear to be characteristic of a glioblastoma subtype; therefore, they do not allow the differentiation between primary and secondary glioblastomas. Also, the loss of a chromosome 10 appears to be an earlier event than a gain of a chromosome 7 for the genesis of a secondary glioblastoma.

Abstract
Glioblastoma multiforme is one of the commonest primary malignant tumours of the brain with rare incidence of extracranial metastases. Systemic dissemination via the CSF or CSF diversionary shunt procedures is also rare. The reported 9-year-old child was a case of thalamic glioblastoma with hydrocephalus who underwent biventriculoperitoneal shunting before tumour decompression and radiotherapy. The child developed incapacitating ascites 8 months following surgical decompression and 9 months after the shunt diversion which was found to be caused by CSF dissemination of the glioblastoma via the ventriculoperitoneal shunt. The child ultimately succumbed to his disease.

Abstract
The use of cellular telephones has increased dramatically during the 1990's in the world. In the 1980's the analogue NMT system was used whereas the digital GSM system was introduced in early 1990's and is now the preferred system. Case reports of brain tumours in users initiated this case-control study on brain tumours and use of cellular telephones. Also other exposures were assessed. All cases, both males and females, with histopathologically verified brain tumour living in Uppsala-Orebro region (1994-96) and Stockholm region (1995-96) aged 20-80 at the time of diagnosis and alive at start of the study were included, 233 in total. Two controls to each case were selected from the Swedish Population Register matched for sex, age and study region. Exposure was assessed by questionnaires supplemented over the phone. The analyses were based on answers from 209 (90%) cases and 425 (91%) controls. Use of cellular telephone gave odds ratio (OR) = 0.98 with 95% confidence interval (CI) = 0. 69-1.41. For the digital GSM system OR = 0.97, CI = 0.61-1.56 and for the analogue NMT system OR = 0.94, CI = 0.62-1.44 were calculated. Dose-response analysis and using different tumour induction periods gave similar results. Non-significantly increased risk was found for tumour in the temporal or occipital lobe on the same side as a cellular phone had been used, right side OR = 2.45, CI = 0.78-7.76, left side OR = 2.40, CI = 0.52-10.9 Increased risk was found only for use of the NMT system. For GSM use the observation time is still too short for definite conclusions. An increased risk for brain tumour in the anatomical area close to the use of a cellular telephone should be especially studied in the future.

Abstract
Hepatocyte growth factor (HGF) is a multifunctional cytokine which is believed to have important roles in tissue development and regeneration, and tumor progression. It is indistinguishable from scatter factor (SF), a motility factor. HGF/SF is believed to be a mesenchymal cell-derived cytokine acting for epithelial cells bearing its receptor tyrosine kinase, c-Met. Recently, we found that glioblastoma multiforme (GBM), a highly malignant brain tumor of astrocytic origin, concomitantly express HGF/SF and c-Met. This finding indicates a presence of autocrine loop of HGF/SF signaling pathway in GBM. Moreover, GBM cells also co-express HGF activator, a recently identified serine proteinase having efficient HGF/SF activating activity. The expression of HGF/SF and c-Met was low or hardly detectable in low-grade astrocytoma, and c-Met immunoreactivity was correlated with the histological grade of the tumor suggesting that the creation of HGF/SF autocrine loop occurs along with the progression of astrocytic brain tumors. Experimental evidence indicated that HGF/SF exhibits potent migration/invasion-inducing activity for GBM cells bearing c-Met receptor. It is also a significant angiogenesis factor in GBM, and may serve as a cellular growth factor for certain GBM cells. These lines of evidence suggest that HGF/SF signaling pathway may serve as a promising new target of therapeutic intervention of GBM.

Abstract
The United States Transuranium and Uranium Registries (USTUR) is a unique postmortem research study of the biokinetics, dosimetry, and possible biological effects of actinide elements in persons with occupational exposure to these radioelements. Evaluation of the causes of death in the admittedly biased self-selected cohort of the first 260 deceased participants in the USTUR revealed, in general, no apparently elevated causes of death except for six cases of mesothelioma and six cases of astrocytoma glioblastoma multiforme. The mesothelioma cases had a documented occupational exposure to asbestos, and the six brain tumor deaths all occurred at a single work site and were not radiation related but rather are likely attributable to a factor specific to the work site or surrounding area. Incidental findings in this cohort did not suggest any radiation related illness or cause of death.

Abstract
We report a case of glioblastoma manifesting 49 years after a lobotomy. He was diagnosed as having schizophrenia at age 20 and was operated on with a standard lobotomy when he was 27 years old. He had led a useful life after 40 years old without medication. Because of hallucination and delusion, he was hospitalized at the end of 1996. CT showed a well enhanced tumor adjacent to the cavity made by the lobotomy in the left frontal lobe. This is the second case report of glioblastoma just beside the cavity formed by lobotomy. The relationship between glioblastoma and old lobotomy is discussed, especially in regard to morphology and CT findings.

Abstract
OBJECTIVE Gangliogliomas are indolent tumors comprised of neoplastic glial and neuronal cells. Benign lesions tend to be associated with long survival unless the tumor degenerates to a histologically malignant form. This study reviews four cases of histologically proven benign ganglioglioma that later demonstrated malignant features within the glial component of the tumor. Features common to each case are analyzed, and similar cases from the literature are reviewed. METHODS The records of 42 supratentorial gangliogliomas operated on at our institution since 1985 were reviewed. Special attention was paid to histological characteristics, use of adjuvant radiotherapy, time to tumor recurrence, and histology of the recurrent tumor. RESULTS Of the 42 cases of gangliogliomas, 29 were initially histologically benign. Of these 29, 14 received postoperative radiation therapy and 14 did not; it was unclear whether one patient received adjuvant radiotherapy, and this patient was excluded from further analysis. Four benign gangliogliomas exhibited malignant degeneration of the glial component. These four all occurred in patients who had undergone postoperative irradiation. The time to identified histological change within recurrent tumors averaged 65 months (range, 22-144 mo). CONCLUSION All of the benign gangliogliomas undergoing malignant change had postoperative radiation therapy as a common feature. This represents a potential correlation that requires further study.

Abstract
OBJECTIVE Tumor neogenesis is an uncommon but known consequence after therapeutic irradiation of the central nervous system. Causative agents for glioma induction remain unknown, but laboratory and clinical data suggest a possible role for radiation as a promotor. In the treatment of both pituitary adenomas and craniopharyngiomas, adjunctive conventional radiation therapy has long played a role. CLINICAL PRESENTATION This report details two cases in which patients received standard sellar irradiation for growth hormone-secreting pituitary adenomas and later were diagnosed with gliomas, after a latency period of 11 and 18 years, respectively. Additionally, a comprehensive review of the literature with 30 reports of gliomas developing after conventional radiation for treatment of pituitary adenomas and craniopharyngiomas is presented. The mean dose for craniopharyngiomas (n = 8) was 5800 cGy, with a mean latency of 11.5 years from initial diagnosis to the eventual discovery of the gliomas. The mean dose for the treatment of pituitary adenomas (n = 24) was 5300 cGy, with a mean latency of 10.4 years. CONCLUSION Typical features of the resulting gliomas included presentation in young patients, histologically high grades, and occurrence within the temporal lobe. A large proportion of gliomas were associated with growth hormone-secreting adenomas. This review assesses the implication of doses of conventional radiotherapy that were previously thought to be benign and concludes that although radiation-associated gliomas are uncommon, they represent a potentially devastating long-term risk. Based on this analysis, treatment of sellar tumors with conventional fractionated radiotherapy should be carefully considered and perhaps used primarily in those cases for which radiosurgery is not appropriate.

Abstract
We have generated a transgenic mouse model for astrocytoma by expressing the v-src kinase under control of the glial fibrillary acidic protein (GFAP) gene regulatory elements in astrocytes. Abnormal astrogliosis was observed in all transgenic animals already at 2 weeks postnatally, frequently followed by the development of dysplastic changes. Later, small proliferative foci arose, and overt astrocytoma developed in the brain and spinal cord in 14.4% of mice after a follow up time of 65 weeks. While early lesions were histologically consistent with low-grade astrocytoma, at later stages most tumors were highly mitotic and frankly malignant. Vascular endothelial growth factor (VEGF) was expressed by tumor cells already at early stages, suggesting induction by v-src, and it was most pronounced in pseudopalisading cells surrounding necrotic areas, implying additional upregulation by hypoxia. In larger lesions, mitotic activity and expression of flk-1, the cognate receptor of VEGF were induced in endothelial cells. Therefore, end-stage tumors mimicked the morphological and molecular characteristics of human glioblastoma multiforme. Time course and stochastic nature of the process indicate that v-src did not suffice for malignant transformation, and that astrocytomas were the result of a multistep process necessitating co-operation of additional genetic events.

Abstract
The transmission of donor-related malignancies by organ transplantation is a rather rare event. There has only been one report on the development of a brain tumor metastasis in liver transplantation. From September 1988 to January 1993, 342 donor hepatectomies with subsequent transplantation were performed at our center. The main donor diagnoses included subarachnoidal bleeding (n = 128; 37.4%), isolated head injury (n = 114; 33.3%), multiple injuries (n = 55; 16.1%), primary cerebral neoplasia (n = 13; 3.8%), and other (n = 32; 9.4%). Primary cerebral neoplasia included glioblastoma (n = 4), meningioma (n = 3), astrocytoma (n = 2), angioma (n = 2), neurocytoma (n = 1), and ependymoma (n = 1). In the group of donors suffering from primary cerebral neoplasia, procured organs other than the liver included kidneys (n = 20), combined kidneys and pancreata (n = 1), pancreata (n = 2), hearts (n = 8), combined hearts and lungs (n = 1), and single lungs (n = 1). Follow-up of the respective graft recipients ranged from 28 to 68 months (median 43 months). Recurrent malignancy was observed once, in a liver graft recipient. The donor, a 48-year-old female, had undergone surgical resection of an intracerebral multiform glioblastoma and died 4 months later of a relapse in the brain stem. The 28-year-old female recipient had undergone transplantation for an autoimmune-hepatitic cirrhosis. Four months later, histopathological examination of an intraperitoneal and intrahepatic mass revealed a poorly differentiated, small-cell pleomorphic cancer, identified as a glioma metastasis by S100- and glial fibrillary acidic protein immunohistochemical staining. The patient died 6 months post-transplantation. On autopsy, no further neoplastic lesions were detected. Our review adds a second reported case of a liver graft-transmitted brain tumor to the literature and the fourth donor-related malignancy after hepatic transplantation in general.

Abstract
An adult female rhesus monkey that had received 44.0 Gy of cobalt 60 radiation to 8 cm of the cervical and upper thoracic spinal cord approximately 2.8 years postirradiation developed a sudden onset of self-mutilation and loss of function of the right arm followed progressively by loss of function of the left arm and terminally bilateral paresis of the legs. Histopathologic examination of the cervical spinal cord revealed a glioblastoma multiforme that extended from the cervical medullary junction to the sixth cervical vertebrae. Because of the infrequent occurrence of spontaneous neoplasia in rhesus monkeys and the location in the radiation field, the glioblastoma is believed to be radiation induced.
