This classification allows for the diagnosis of isocitrate dehydrogenase wild-type (IDHwt) glioblastoma (GBM), and WHO grade 4 with histologically lower-grade gliomas (LrGGs), even in the absence of high-grade histopathologic features, such as necrosis and/or microvascular proliferation. They ...
Gliomas are tumors of astroglial origin and the World health Organization (WHO) classifies them based on histological criteria into four grades of ascending malignancy. Glioblastoma multiforme (GBM, WHO grade IV) is among the most lethal of human cancers
Glioblastoma multiforme (GBM, WHO grade 4) is the most frequently occurring malignant central nervous system tumor with a global incidence of 0.59–3.69 per 100 000.1 It is by far the most common and malignant of all glial tumors, and is associated with poor prognosis with a median patient...
Glioblastoma Grade IV (GBM) is a highly aggressive and malignant tumour, accounting for 50% of all the gliomas1,2 predominantly occurring in adults. The therapy regime includes maximum debulking of the tumour through surgery, followed by radiation and adjuvant chemotherapy using alkylating agents like...
There is currently no cure for GBM. [2] The standard of care (SOC) for grades 3 or 4 high-grade gliomas (HGGs) including GBM, a grade 4 glioma, currently relies on maximally safe surgical resection followed by concurrent radiation therapy and temozolomide (TMZ). [4] While this SOC has...
Glioblastoma (GBM, grade IV glioma)2 represent the most frequent and aggressive malignant primary brain tumors in humans. GBMs encompass secondary GBMs (about 5% of the cases) which develop from lower-grade diffuse astrocytoma (WHO grade II) or anaplastic astrocytoma (WHO grade III), and primar...

We have tested our system on Glioblastoma Multiforme (GBM), one of the most common and the least curable brain cancer, with glioma cells infiltrating the surrounding tissue with a median survival rate of 14.6 month [2]. Figure 1 shows that the tissue section has a rich spatial composition (...
Utilizing data from Gene Expression Profiling Interactive Analysis, it was found that Ca+2calmodulin gene expression was higher in GBM and low grade glioma than other brain tumors. [96] The three calmosulin genes are associated with different functions according to the state of the cell. Some ...
Moreover, in primary GBM, HILPDA expression was significantly higher in the pseudopalisading region of the tumor. The increase in HILPDA expression in only GBM and not lower-grade brain tumors, combined with the specific increase in pseudopalisading regions, is consistent with brain tumor ...
