ANALYTICAL ANALYSIS OF THE CONDITION OF PATIENTS WITH BRAIN TUMORS AFTER RADIATION THERAPY

Abstract

Relevance. The number of oncological diseases is growing from year to year. This is due to the widespread use of computer-based visualized research methods in the modern world. Brain tumors occupy a special place among oncopathology. The treatment of brain tumors is an urgent problem of modern neuro-oncology, since the survival rate of patients remained low until recently, and the disease itself led to an increase in cases of disability and a decrease in quality of life. Along with surgical and drug treatment methods, radiation therapy is currently widely used, which allows for long-term remission, even complete recovery, in some diseases. Modern innovative methods of radiation therapy in combination with other types of therapy undeniably increase the survival of patients, especially with primary brain tumors. The main goal of radiation therapy is to increase the effectiveness of targeted impact on the tumor with minimal radiation exposure to healthy organs and tissues. Radiation therapy for brain tumors can be performed using whole brain radiation therapy (WBRT), classical conformal radiation therapy, stereotactic radiation surgery (SRS), stereotactic radiation therapy (SRT). The effectiveness of radiation therapy against tumor cells is achieved by high doses of ionizing radiation, which in turn increases the risk of developing radiation necrosis (RN) of brain tissue in the irradiated area. The risk of ROP also increases with the volume of brain parenchyma and the radiation dose.
