[Possibilities of stereotactic radiotherapy in the palliative treatment of patients with pancreatic cancer].

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.

[The role of stereotactic radiotherapy in the treatment of patients with liver metastases].

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.

[Complex treatment of breast cancer patients with brain metastases].

Brain metastases in breast cancer develop for 24-32 months after the detection of the primary tumor. The study included patients with brain metastases who were divided into three groups: the first group--with early chemoradiotherapy (CRT) without induction chemotherapy (IC) by capecitabine; the second group--with delayed CRT with 4 or 8 courses of IC by capecitabine; the third group (a historical control) who received only whole brain radiation therapy. The median time to progression of intracranial metastases was 15.

[Thermoradiotherapy as a component of desmoid tumor management: 10-year experience].

Data on radio- and thermoradiotherapy of 83 patients with extra-abdominal desmoid tumors are discussed. In a group of 57 patients followed up for 10 years or less, the relapse-free survival rates, in thermoradiotherapy-treated cases, were significantly higher (74.4% and 28.
