Abstract
Today, radiotherapy plays a crucial role in the treatment of malignant brain tumors. At the same time, in general, recent advances in clinical oncology concerning modern methods of radiotherapeutic treatment of malignant neoplasms, in contrast to the already traditional 3D-conformal radiotherapy (3D-CRT), include its use with modulated intensity (IMRT), volume-modulated arc therapy (VMAT) and stereotactic radiosurgery (SRS). All these methods make it possible to deliver higher doses of radiation to the target volume, while at the same time reducing the risk of increased toxicity to normal tissues, compared to the already traditional 3D conformal radiotherapy (3D-CRT). Moreover, proton therapy can currently be an alternative to photon irradiation due to a more favorable dose distribution over the target volume. In the presented first part of the general review concerning the problem of "Metastases of malignant tumors in the brain", a brief report is offered on the latest technological achievements in radiotherapy of malignant brain tumors and their clinical impact on the special treatment of this category of neuro-oncological patients.
