Abstract
Background: Glioblastoma is the most common and malignant form of primary brain cancer; it is characterized by one of the highest mortality among human cancers. Maximal and aggressive surgical resection is the first approach treatment even if not usually definitive, being the tumor characterized by a high proliferative rate and extensive invasion. Early diagnosis, associated to careful monitoring, is pivotal in glioblastoma treatment; Magnetic Resonance Imaging is used for monitoring purpose, but it’s not sensitive enough to detect very small tumors; a valid alternative could be a repeated biopsy, but it is associated to a significant morbidity: less invasive options for diagnosis and therapeutic monitoring are unfailingly researched.
Methods: A careful search was performed on PubMed, mainly considering papers in the last 10 years. Conclusion: In recent years it has begun to take hold the knowledge that glioblastoma cells secrete extracellular vesicles (microvesicles and exosomes), which mirror the molecular features of parental cells and are able to escape from tumor microenvironment, reaching cerebrospinal fluid and systemic blood circulation. Such information led to consider the possibility to use extracellular vesicles in biological fluids as markers of glioblastoma pathology and to use them as a more feasible “liquid-biopsy” to gain diagnostic information, follow the disease progression and the response to clinical treatment, just through a blood test or cerebrospinal fluid collection. The most interesting extracellular vesiclesassociated molecules studied as glioblastoma markers are taken into account, as well as approaches aiming to use extracellular vesicles as cell-free vaccines or vehicle of therapeutic molecules.Keywords: Cells irradiation, exosomes, extracellular vesicles, glioblastoma, glioblastoma markers, microvesicles, U251 cells.

Advances in Cancer Biomarkers and Potential Drug Targets: From Diagnosis to Therapy
Cancer biomarkers play a crucial role in the diagnosis, prognosis, and treatment of cancer. They provide valuable information for cancer detection, risk assessment, treatment selection, and monitoring response to therapy. With advancements in molecular biology and high-throughput technologies, there has been an increasing interest in identifying and characterizing cancer biomarkers ...read more
Novel Therapeutic Approaches to Target Drug Resistant Tumors
With the development of disciplines such as chemical biology and molecular biology, the genes or proteins closely related to tumor occurrence and development have gradually become clear. Targeted therapies targeting these genes or proteins provide more effective methods for tumor treatment. Tumor targeted drugs generally only act on specific targets ...read more
ROLE OF IMMUNE AND GENOTOXIC RESPONSE BIOMARKERS IN TUMOR MICROENVIRONMENT IN CANCER DIAGNOSIS AND TREATMENT
Biological biomarkers have been used in medical research as an indicator of a normal or abnormal process inside the body, or of a disease. Nowadays, various researchers are in process to explore and investigate the biological markers for the early assessment of cancer. DNA Damage response (DDR) pathways and immune ...read more
Targeting the battlefield between host and tumor: basic research and clinical practice on reshaping tumor immune microenvironment
Immune system protects host against malignant tumors through effector cells and molecules. Cancer development and its response to therapy are regulated by inflammation, which either promotes or suppresses cancer progression. Chronic inflammation facilitates cancer progression and treatment resistance, whereas induction of acute inflammatory reactions often lead to anti-cancer immune responses. ...read more
