Part of one lateral ventricle is often distorted, and both lateral and third ventricles may be displaced contralaterally (Fig 31-2) The characteristic histologic ndings of glioblastoma are great cellularity with pleomorphism of cells and nuclear atypia; identi able astrocytes with brils in combination with primitive forms in many cases; tumor giant cells and cells in mitosis; hyperplasia of endothelial cells of small vessels; and necrosis, hemorrhage, and thrombosis of vessels This variegated appearance distinguishes glioblastoma from the anaplastic astrocytomas, which show frequent mitoses and atypical cytogenic features but no grossly necrotic or hemorrhagic areas It is the necrotic and sometimes cystic areas that appear hypointense on imaging studies The vasculature and broblasts undergo a sarcomatous transformation with prominent reticulin and collagen in surrounding tissue The vascular and connective tissue changes suggest the elaboration of a growth factor by the tumor tissue Originally, the glioblastoma was thought to be derived from and composed of primitive embryonal cells, but it is now generally thought to arise through anaplasia of maturing astrocytes It should be emphasized that the histologic grade may vary from site to site within a tumor and it is common for sites of anaplastic astrocytoma and glioblastoma to coexist; in some tumors there are even sites of well-differentiated astrocytoma It is a fair statement that the most aggressive component (eg, glioblastic elements) determines the tumor s behavior To some extent, this behavior is related to some of the aforementioned genetic changes Ampli cation of the epidermal growth factor receptor gene (EGFR) is characteristic of older patients with tumors that begin entirely as glioblastomas, while mutations on the TP53 gene tend to occur in younger individuals whose tumors progress from an astrocytoma to a glioblastoma

.

The natural history of untreated glioblastoma is well known Less than one- fth of all patients survive for 1 year after the onset of symptoms, and only about 10 percent live beyond 2 years (Shapiro) Age is the most important prognostic factor in this group of tumors; fewer than 10 percent of patients over age 60 survive for 18 months, in comparison to two-thirds of patients under age 40 Survival with anaplastic astrocytoma is somewhat better, typically 3 to 5 years Cerebral edema and increased intracranial pressure are usually the immediate causes of death Survival rates with treatment are discussed below The diagnosis must usually be con rmed by a stereotactic biopsy or by a craniotomy that aims to remove as much tumor as is feasible at the same time At operation, only part of the tumor can be removed; its multicentricity and diffusely in ltrative character defy the scalpel Partial resection of the tumor ( debulking ), however, seems to prolong survival slightly Treatment Except for palliation, little can be done to alter the course of glioblastoma For a brief period, corticosteroids, usually dexamethasone in doses of 4 to 10 mg every 4 to 6 h, are helpful if there are symptoms of mass effect such as headache or drowsiness; local signs and surrounding edema tend to improve as well Anticonvulsants are not required unless there have been seizures, but some neurologists and neurosurgeons administer them in order to pre-empt a convulsion Serious skin reactions (erythema multiforme and Stevens-Johnson syndrome) may occur in patients receiving phenytoin at the same time as cranial radiation (Delattre et al) Usually a maximally feasible resection, the debulking described above, is combined with external beam radiation and chemotherapy Total cranial irradiation (4500 cGy), boosted with a dose to the region of the tumor (1500 to 2000 cGy), increases survival by.

ansa sweeps around the internal capsule; the fasciculus traverses the internal capsule in a number of small fascicles and then continues medially and caudally to join the ansa in the prerubral eld Both of these ber bundles join the thalamic fasciculus, which then contains not only the pallidothalamic projections but also mesothalamic, rubrothalamic, and dentatothalamic ones These projections are directed to separate targets in the ventrolateral nucleus of the thalamus and to a lesser extent in the ventral anterior and intralaminar thalamic nuclei The centromedian nucleus of the intralaminar group projects back to the putamen and, via the parafascicular nucleus, to the caudate A major projection from the ventral thalamic nuclei to the ipsilateral premotor cortex completes the large cortical-striatal-pallidal-thalamic-cortical motor loop (the prepyramidal circuit, mentioned above) with conservation of the somatotopic arrangement of motor bers, once again emphasizing the nexus at the thalamic nuclei
