Impact of age and gender on glioblastoma onset, progression, and management

2023

Glioblastoma (GBM) is the most common primary malignant brain tumor in adults, while its frequency in pe-diatric patients is 10-15%. For this reason, age is considered one of the major risk factors for the development of GBM, as it correlates with cellular aging phenomena involving glial cells and favoring the process of tumor transformation. Gender differences have been also identified, as the incidence of GBM is higher in males than in females, coupled with a worse outcome. In this review, we analyze age-and gender-dependent differences in GBM onset, mutational landscape, clinical manifestations, and survival, according to the literature of the last 20 years, focusing on the major risk fa…

HGG-03. THE GLYCOSPHINGOLIPIDS METABOLISM IS A NOVEL TARGET IN H3K27M-MUTANT DIFFUSE MIDLINE GLIOMA

2021

Abstract H3K27M-mutant diffuse midline glioma (H3K27M-mutant DMG) is a rare malignant brain tumour entity in children and adults with a median overall survival of around 12 months. Genomic and proteomic analysis may help to identify new target structures, however not all relevant targets are covered by these analyses. Glycosphingolipids and particularly gangliosides play a major role in brain development and have been involved in the pathology of brain tumours. The conversion of ceramide to glucosylceramide via glucosylceramide synthase (GCS) is one of the first steps in the synthesis of glycosphingolipids. Therefore, targeting GCS will inhibit their synthesis. Here we analysed the glycosph…

Brain mapping as helpful tool in brain glioma surgical treatment—Toward the “perfect surgery”?

2018

Gliomas are the most common primary malignant brain tumours in adults, representing nearly 80%, with poor prognosis in their high-grade forms. Several variables positively affect the prognosis of patients with high-grade glioma: young age, tumour location, radiological features, recurrence, and the opportunity to perform post-operative adjuvant therapy. Low-grade gliomas are slow-growing brain neoplasms of adolescence and young-adulthood, preferentially involving functional areas, particularly the eloquent ones. It has been demonstrated that early surgery and higher extent rate ensure overall longer survival time regardless of tumour grading, but nowadays, functional preservation that is as…

Current regimen for high-grade gliomas is maximal safe surgical resection followed by external beam radiotherapy with concurrent temozolamide. Maximal tumor resection, however, must be balanced with preservation of the patient’s neurological function. A crucial prognostic factor in oncological neurosurgery is the extent of resection. Several studies have addressed the importance of extent of resection in gliomas surgery. Despite development in the fields of pre operative and intraoperative neuroimaging and neuromonitoring have ameliorated the survival rate and the quality of life for patients affected by high grade gliomas, the clinical outcome of patients with such gliomas remains extremel…
