Abstract: Glioblastoma Multiforme (GMB) is the most aggressive primary brain tumor with poor survival rates and universal recurrence
despite aggressive treatments. Recent research suggested that GBM has multiple glioma cell populations, some of which are organized in a
stem cell hierarchical order with different stages of differention. Evidence indicated that recurrence is due to a development or persistance of
a subpopulation of these tumor cells which are inherently resistant to treatment and these were defined as the glioma stem-like cells
(GSC). It is hypothesized that GSC become highly malignant by accumulating mutations in oncogenic pathways. These cells present with
specific surface markers which helps identify them. Targeting the surface markers as well as the signaling pathways of GSCs has been an
ongoing research effort. This review focuses on summarizing the current treatment modalities used to glioblastoma treatments, evaluating
their efficacy in controlling and eradicatig the GSCs, discussing the machanisms involved in GSC tumor proliferation and resistance to
treatments in addition to proposing potential avenues to target GSCs in order to provide a potential cure for this cancer.
