Astrocytoma, the tumor of astrocytic glial cells, is the most common type of central nervous system (CNS) neoplasms, accounting for more than 60% of all primary brain tumors.4 Diffuse infiltrating astrocytomas are divided into low-grade diffuse astrocytoma (DA; grade II), anaplastic astrocytoma ...
infusions. Eight patients were reoperated when clinical deterioration suggested recurrent tumor; histological examination showed no residual tumor in 7 of them. Of these 8 patients 3 are alive and well, 2 of them after more than 5 years. The study suggests that malignant astrocytoma can be ...
Malignant astrocytoma (MA) is the most common and severe type of brain tumor. A greater understanding of the underlying mechanisms responsible for the development of MA would be beneficial for the development of targeted molecular therapies. In the present study, the upregulated differentially expresse...
Background: Astrocytomas are the most common and aggressive brain tumors characterized by their highly invasive growth. Gain of chromosome 7 with a hot spot at 7q32 appears to be the most prominent aberration in astrocytoma. Previously reports have shown that microRNA-335 (miR-335) resided on...
To date, surgery and irradiation remain the standard therapies for anaplastic astrocytoma (AA, WHO grade III) and glioblastoma multiforme (GBM, WHO grade IV). Due to infiltrative tumor growth a complete surgical resection is never achieved and more than 90% of the tumors will recur within 2cm ...
Furthermore, in astrocytoma, especially glioblastoma, focus of anaplastic tumor cells appeared with CD34 expression, whereas some tumor cells lost glial ... WY Yue,ZP Chen - 《Journal of Histochemistry & Cytochemistry》 被引量: 248发表: 2005年 Interstitial microwave hyperthermia for brain tumors. ...
Notes: aSomeAAs containing oligodendroglial components are classified as anaplastic oligoastrocytomas (AOA). Abbreviations: AA, anaplastic astrocytoma; GBM, glioblastoma multiforme;WHO, World Health Organization. nAA include providing tissue for an accurate pathologic diagnosis as well as tumor ...
Malignant astrocytomas are infiltrative and incurable brain tumors. Despite profound therapeutic implications, the identity of the cell (or cells) of origin has not been rigorously determined. We previously reported mouse models based on conditional inactivation of the human astrocytoma-relevant tumor ...
