Abstract BACKGROUND Evidence suggests that smaller residual tumor volumes after initial surgery are associated with longer survival in patients astrocytoma, IDH-mutant, grade II. For IDH-mutant glioma of higher but also for oligodendroglioma, and 1p/19q codeleted, the impact volume on is unclear. This could be related to limited follow-up oligodendroglioma typically have long overall survival. ...

- astrocytomas, including glioblastoma multiforme (gbm), arc the most common brain tumors. post-operative radiotherapy plays an important rote in their treatment. records of all patients with a pathologic diagnosis of astrocytoma referred for radiotherapy from 1987-1992 were reviewed and prognostic factors with regard to recurrences were analyzed. during the study period, 162 astrocytoma patien...

A case of cerebellar medulloblastoma with transitional features towards malignant fibrillary astrocytoma is described. In the cerebellum the tumour is characterised by extensive subpial infiltration with cells of undifferentiated type, and the astrocytic component could only be identified by a positive glial fibrillary acidic protein reaction. In the brainstem the character of the growth transf...

Since the recent publication of the World Health Organization brain tumour classification guidelines in 2007, a significant expansion in the molecular understanding of glioblastoma multiforme (GBM) and its pathological as well as genomic variants has been evident. The purpose of this review article is to evaluate the histopathological, molecular and clinical features surrounding emerging and cu...

Multiple primitive intracranial tumors with different histological characteristics are uncommon. Although coexistence of a medulloblastoma with glial tumors has been reported in children, medulloblastoma is rarely found in adults, especially those older than 40 years of age. We present an extremely rare case of a medulloblastoma developing in a 40-year-old male undergoing maintenance chemothera...

Thirty-two cases of surgically removed astrocytoma were evaluated for the expression of androgen receptors(ARs) immunohistochemically and the relationships between androgen receptors, DNA ploidy pattern, and survival of patients were studied. The cases included 18 grade I/II astrocytomas, 4 anaplastic astrocytomas, and 10 glioblastoma multiforme(GBM). Positive AR was present in 12 out of 32 cas...

Breast cancer is the most common cancer in women. Multicentric gliomas are uncommon lesions of the central nervous system (CNS) with an unprecise rate of occurrence that diffusely infiltrate large portions of the brain. High grade astrocytoma is the most agressive form of gliomas and often has a distinct neuroimaging pattern with a poor prognosis. We report a case of a 29-year-old woman patient...

PURPOSE To report the occurrence of an astrocytoma of the ciliary body. METHODS The patient was evaluated by ophthalmoscopic examination (including color ultrasonography and ultrasound biomicroscopy) as well as operating therapy. Histopathology and immunocytochemical analysis were performed. RESULTS A 29-year-old woman was found to have a left ciliary body tumor. Color ultrasonography revea...
