Highlights ■ The molecular test according to the WHO classification of CNS tumors (gliomas) was performed in 100% (172) of patients. ■ Education on chemotherapy and informed consent for patients with brain tumors was carried out for 100% (130) of the patients who had an indication for chemotherapy treatment. ■ Approximately 87% of the patients with gliomas underwent postoperative cranial MRI. ■ A multidisciplinary approach, including molecular testing, was used for 35% of patients with glioma. ■ Thromboembolic events after […]

OBJECTIVE: To assess intracellular labeling and quantification by magnetic resonance imaging using iron oxide magnetic nanoparticles coated with biocompatible materials in rat C6 glioma cells in vitro. These methods will provide direction for future trials of tumor induction in vivo as well as possible magnetic hyperthermia applications. METHODS: Aminosilane, dextran, polyvinyl alcohol, and starch-coated magnetic nanoparticles were used in the qualitative assessment of C6 cell labeling via light microscopy. The influence of the transfection agent poly-L-lysine on cellular uptake was […]

OBJECTIVE: The aim of the current study was to monitor the migration of superparamagnetic iron oxide nanoparticle (SPION)-labeled C6 cells, which were used to induce glioblastoma tumor growth in an animal model, over time using magnetic resonance imaging (MRI), with the goal of aiding in tumor prognosis and therapy. METHODS: Two groups of male Wistar rats were used for the tumor induction model. In the first group (n=3), the tumors were induced via the injection of SPION-labeled C6 cells. In […]

ABSTRACT Gliomas comprise a group of heterogeneous primary tumors of the central nervous system that originate from glial cells. Malignant gliomas account for the majority of primary malignant CNS tumors and are associated with high morbidity and mortality. Glioblastoma is the most frequent malignant glioma, and despite recent advances in diagnosis and new treatment options, its prognosis remains dismal. New opportunities for the development of effective therapies for malignant gliomas are urgently needed. Magnetohyperthermia consists of heat generation in the […]
