Abstract Background Glioblastoma multiform is the most common and aggressive type of primary malignant tumor that affects central nervous system in adults. It clinically presents with seizures, headache, and/or progressive focal neurological deficits. Radiologically, glioblastoma appears as a single distinguishable, large heterogeneous lesion affecting cerebrum characteristic necrosis, marginal...

Glioblastoma multiform (GBM) is the most common and lethal type of primary brain tumors with high rates of morbidity and mortality. Treatment options are limited and ineffective in most of the cases. Epidemiological studies have shown a link between inflammation and glioma genesis.  In addition, at the molecular level, pro-inflammatory cytokines released from activated microglia can increa...

An altered expression of microRNAs (miRNAs) contributes both to the development of cancer and to the progression of the disease. Malignant tumours and tumour cell lines have widespread deregulated expressions of miRNAs compared to normal tissues. In this study, we investigated the expression profiles of 340 mammalian miRNAs in 93 cases of multiform glioblastoma (primary and secondary glioblasto...

 Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...

Malignant gliomas are the most frequent primary brain tumors in adults. Temozolomide is an oral alkylating cytotoxic agent of second generation, used in the treatment of high-grade gliomas. It is indicated in newly diagnosed glioblastoma multiform as well as in recurrent or progressive malignant gliomas, such as glioblastoma multiform or anaplastic astrocytoma. However, temozolomide is also use...

Conventional magnetic resonance imaging (cMRI) has an established role as a crucial disease parameter in the multidisciplinary management of glioblastoma, guiding diagnosis, treatment planning, assessment, and follow-up. Yet, cMRI cannot provide adequate information regarding tissue heterogeneity infiltrative extent beyond contrast enhancement. Advanced PET newer analytical methods are transfor...

Many studies have focused on the prognosis role of insulin-like growth factor binding protein 2 (IGFBP2) in glioma patients, but the results remain inconsistent. Thus, a meta-analysis was carried out to explore the relationship between IGFBP2 and glioma prognosis. Relevant publications were searched in several widely used databases and six articles (seven studies, 766 patients in all) were incl...

background : gliomas are the most common primary brain tumors of the central nervous system. among a number of different bio-molecular events, molecular connections between oxidative stress pathways and their development is prevalent. oxidative stress is the consequence of an imbalance between pro-oxidant factors and antioxidant defense. this imbalance may lead to dna damage and changes in grow...
