Emerging Therapies for Glioblastoma

Area of Science:

• Neuro-oncology
• Cancer Biology
• Biomedical Engineering

Background:

• Glioblastoma is the most malignant primary brain tumor with a poor prognosis.
• Tumor heterogeneity complicates treatment strategies.
• Current therapies (temozolomide, radiation, surgery) have limited efficacy.

Purpose of the Study:

• To review alternative and novel treatment strategies for glioblastoma.
• To discuss targeted therapies and emerging modalities like oncolytic viruses and nanomaterials.

Main Methods:

• Literature review of current and emerging glioblastoma treatments.
• Analysis of targeted therapies for specific molecular pathways (PI3K, NFKβ, JAK-STAT, CK2, WNT, NOTCH, Hedgehog, TGFβ).
• Evaluation of oncolytic viruses and nanomaterials for glioblastoma therapy.

Main Results:

• Targeted therapies show promise in preclinical and clinical studies.
• Oncolytic viruses offer a novel approach to selectively destroy cancer cells.
• Nanomaterials facilitate drug delivery and overcoming the blood-brain barrier.

Conclusions:

• Despite advances, glioblastoma remains a significant clinical challenge.
• Targeted therapies, oncolytic viruses, and nanomaterials represent promising avenues.
• Combination treatments and improved drug delivery are crucial for future glioblastoma therapies.
