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.

Morbidity and mortality from pancreatic cancer is steadily increasing. Resectable cases are not more than 20%. Conventional schemes of chemoradiation and radiation therapy are durable over the time, have toxicity and low treatment outcomes. Many foreign authors consider as promising the technique of stereotactic radiotherapy, which is often used in pancreatic cancer and permit achieving high local control. At our institution there has been developed and introduced into clinical practice a method of stereotactic radiotherapy for the palliative treatment of patients with pancreatic cancer, which improved not only the duration but also the quality of life of patients.
