Abstract:
Glioblastoma (GBM) is aggressive malignant tumor residing within the central nervous system. Although the standard treatment options, consisting of surgical resection followed by combined radiochemotherapy, have long been established for patients with GBM, the prognosis is still poor. Despite recent advances in diagnosis, surgical techniques, and therapeutic approaches, the increased patient survival after such interventions is still sub-optimal. The unique characteristics of GBM, including highly infiltrative nature, hard-to-access location (mainly due to the existence of the blood brain barrier), frequent and rapid recurrence, and multiple drug resistance mechanisms, pose challenges to the development of an effective treatment. To overcome current limitations on GBM therapy and devise ideal therapeutic strategies, efforts should focus on an improved molecular understanding of GBM pathogenesis. In this review, we summarize the molecular basis for the development and progression of GBM as well as some emerging therapeutic approaches.

- Malignant brain tumors
Background:
- Glioblastoma (GBM) is an aggressive central nervous system malignancy with poor patient prognosis despite standard treatments.
- Current therapeutic strategies for GBM face challenges due to tumor invasiveness, blood-brain barrier penetration, rapid recurrence, and drug resistance.
- Sub-optimal survival rates highlight the need for improved understanding and novel therapeutic approaches for GBM.
Purpose of the Study:
- To review the molecular mechanisms underlying glioblastoma development and progression.
- To explore emerging therapeutic strategies aimed at overcoming current treatment limitations for GBM.
- To provide insights into the molecular pathogenesis of GBM for the development of effective therapies.
Main Methods:
- Literature review of molecular mechanisms in GBM pathogenesis.
- Analysis of current and emerging therapeutic strategies for glioblastoma.
- Synthesis of information on GBM's biological characteristics and treatment challenges.
Main Results:
- Glioblastoma exhibits complex molecular alterations driving its aggressive behavior.
- Key challenges in GBM treatment include its infiltrative nature, blood-brain barrier, and resistance mechanisms.
