Despite significant advancements in understanding the causes and progression of tumors, cancer remains one leading death worldwide. In light advances therapy, there has been a growing interest drug repurposing, which involves exploring new uses for medications that are already approved clinical use. One such medication is edaravone, currently used to manage patients with cerebral infarction amyotrophic lateral sclerosis. Due its antioxidant anti-inflammatory properties, edaravone also investigated potential activities treating cancer, notably as an anti-proliferative cytoprotective against side effects induced by traditional therapies. This comprehensive review aims provide updates on various applications therapy. It explores standalone antitumor drug, either alone or combination other medications, well role adjuvant mitigate conventional anticancer treatments.

Advances in neuro-oncology have transformed the diagnosis and management of brain tumors, which are among most challenging malignancies due to their high mortality rates complex neurological effects. Despite advancements surgery chemoradiotherapy, prognosis for glioblastoma multiforme (GBM) metastases remains poor, underscoring need innovative diagnostic strategies. This review highlights recent imaging techniques, liquid biopsies, artificial intelligence (AI) applications addressing current challenges. Advanced including diffusion tensor (DTI) magnetic resonance spectroscopy (MRS), improve differentiation tumor progression from treatment-related changes. Additionally, novel positron emission tomography (PET) radiotracers, such as 18F-fluoropivalate, 18F-fluoroethyltyrosine, 18F-fluluciclovine, facilitate metabolic profiling high-grade gliomas. Liquid biopsy, a minimally invasive technique, enables real-time monitoring biomarkers circulating DNA (ctDNA), extracellular vesicles (EVs), cells (CTCs), tumor-educated platelets (TEPs), enhancing precision. AI-driven algorithms, convolutional neural networks, integrate tools accuracy, reduce interobserver variability, accelerate clinical decision-making. These innovations advance personalized neuro-oncological care, offering new opportunities outcomes patients with central nervous system tumors.

ABSTRACT Cranial irradiation or radiotherapy (CRT) is one of the essential therapeutic modalities for central nervous system (CNS) tumors, and its efficacy well known. Nevertheless, CRT also associated with brain damages such as focal cerebral necrosis, neuroinflammation, microvascular anomalies, neurocognitive dysfunction, hormone deficiencies in children. Children's brains are much more sensitive to compared adult's brains. Thus, children's likely develop long‐term complication, which severely lessens their quality life after treatment. juvenile rat led a retardation growth cerebellum; both gray white matter neurogenic regions like subventricular zone dentate gyrus hippocampus were predominantly vulnerable CRT.
