PURPOSE We present preclinical data showing the in vitro intranuclear uptake of motexafin gadolinium by glioblastoma multiforme cells, which could serve as a prelude to the future development of radiosensitizing techniques, such as gadolinium synchrotron stereotactic radiotherapy (GdSSR), a new putative treatment for glioblastoma multiforme. EXPERIMENTAL DESIGN In this approach, administratio...

We present a case of metastatic malignant melanoma in a patient initially diagnosed with glioblastoma multiforme, giant cell variant. A forty year old female presented to our institution for a re-resection of a recurrent right parietal lobe mass, presumed to be recurrent glioblastoma multiforme. PET scan during preoperative evaluation revealed a 3 cm left lower lobe lung mass. Metastatic gliobl...

We report the case of a woman with relapsed glioblastoma multiforme (GBM) who recently gave birth. She announced her pregnancy shortly after the sixth cycle of a dense regimen of temozolomide, prescribed for treating the first recurrence of glioblastoma. Three years ago, in April 2008, she had undergone gross total resection of a glioblastoma multiforme in the postcentral region of the right he...

Gliosarcoma is rare central nervous system tumour and a variant of glioblastoma multiforme with bimorphic histological pattern of glial and sarcomatous differentiation. It occurs in elderly between 5(th) and 6(th) decades of life and extremely rare in children. It is highly aggressive tumour and managed like glioblastoma multiforme. A 12-year-old female child presented with complaints of headac...

RATIONALE Primary spinal glioblastoma multiforme (GBM) is a rare clinical entity with an aggressive course and an invariably dismal prognosis. Its clinical characteristics, radiologic and pathologic findings, and treatment protocols have been discussed in a few cases. PATIENT CONCERNS A 15-year-old female was admitted to the neurology department with a chief complaint of progressive numbness ...

G lioblastoma multiforme is the most aggressive of the gliomas, a collection of tumors arising from glia or their precursors within the central nervous system. Clinically, gliomas are divided into four grades; unfortunately, the most aggressive of these, grade 4 or glioblastoma multiforme (GBM), is also the most common in humans. Because most patients with GBMs die of their disease in less than...

Glioblastoma multiforme is an aggressive astrocytic tumour with poor prognosis. Multifocal glioblastomas are uncommon lesions which can mimic secondaries,but treatment of these two disease entities is considerably different. Histopathology and immunohistochemistry are imperative for arriving at the correct diagnosis and planning the mangement. Here we present a case of multifocal glioblastoma, ...

MicroRNAs (miRNAs) are increasingly implicated in regulating cancer initiation and progression. In this study, two miRNAs, miR-25 and -32, are identified as p53-repressed miRNAs by p53-dependent negative regulation of their transcriptional regulators, E2F1 and MYC. However, miR-25 and -32 result in p53 accumulation by directly targeting Mdm2 and TSC1, which are negative regulators of p53 and th...

Spinal glioblastoma multiforme is not common among spinal cord tumors. According to our literature review, only 27 cases originating from the conus medullaris were reported. We herein reported a case of a 10-year-old child diagnosed with glioblastoma multiforme. The patient received adjuvant radiotherapy and standard temozolomide chemotherapy after total excision. Intracranial lesions were foun...

Tumors exhibit complex organization and contain a variety of cell populations. The realization that the regenerative properties of a tumor may be largely confined to a cell subpopulation (cancer stem cell) is driving a new era of anti-cancer research. Cancer stem cells from Glioblastoma Multiforme tumors express markers that are also expressed in non-cancerous neural stem cells, including nesti...
