Longitudinal Analysis of the Health-related Quality of Life in Glioma Patients
Gliomas are the most common primary intracranial tumors, representing at least 75% of all primary malignant brain tumors. Histopathologically, gliomas are classified into different subgroups including astrocytomas (60-70%), oligodendrogliomas (10-30%), ependymomas (<10%) and mixed gliomas (i.e. oligoastrocytomas) depending on the cell type from which they originate. The World Health Organization …
