ВОЗМОЖНОСТИ СТЕРЕОТАКСИЧЕСКОЙ РАДИОХИРУРГИИ ПРИ ЛЕЧЕНИИ БОЛЬНЫХ С МЕТАСТАТИЧЕСКИМ ПОРАЖЕНИЕМ ПЕЧЕНИ

The introduction of innovative technical developments: the three-dimensional planning, using multileaf collimator, simulated by the intensity radiation therapy, improved methods of fixation significantly improved ability of accurate delivering and escalating of doses of ionizing radiation to the selected volume of tissues. This has changed the perception of the role of radiation therapy in the treatment of liver metastases. Foreign authors data suggest the possibility of reaching 95% local control one year after stereotactic radiotherapy, 92% - after two years (and 100% for tumors smaller than 3 cm.) with the development third or higher degree of radiation damage near in 2%. In 2011, after the technical upgrading of Blokhin Cancer center, the method of stereotactic radiosurgery (SBRS) was introduced in clinical practice for the treatment of patients with liver metastases. This method allows to create a high-dose ionizing radiation in metastatic tumor and cause the destruction of the tumor. This is a promising direction in the treatment of metastatic liver cancer significantly expanded the capabilities of the combined treatment. The article provides an overview of the literature on the treatment of liver metastases, and we publish the results of the use of stereotactic radiosurgery at thirty-five patients with liver metastases and clinical case of successful application of this method in patient with significant co-morbidity.
