RESUMO
Application of modern linear electron accelerators, equipped with precise navigation systems, maximum conformal dose delivery as well as imaging of irradiated focus significantly increased possibilities of escalating of doses of ionizing radiation in a selected volume with the necessary protection of the surrounding critical structures. These technological solutions and modern ideas about possibilities of remote beam radiation therapy resulted in a significant increase of the role of radiation therapy and, in particular, stereotactic radiotherapy in the treatment of patients with liver metastases. This technique allows creating locally in metastatic tumor site a high dose of ionizing radiation causing by that the destruction of the tumor. This promising direction in treatment of liver metastases significantly expanded possibilities of complex treatment and enabled us to provide specific assistance to those patients who have been rejected from other methods of treatment.

Since February 2012, in order to increase the effectiveness of treatment and quality of life of patients with disseminated disease, there was developed and implemented a method of stereotactic radiotherapy for metastatic lesion of lungs by tumors of different histological types. 20 patients were treated by stereotactic radiotherapy ROD 7 Gy in five sessions during 5 days. There were evaluated results of treatment and prospects of this method.
