[Effectiveness of super-fractionated irradiation in the radiotherapy of inoperable lung cancer].

The paper is concerned with the results of gamma-beam therapy of 120 patients with inoperable lung cancer using the fractionation of a common daily dose of 2-2.2 Gy into 2 equal fractions as a variant of super-fractionated irradiation used in clinical practice. The direct and short-term therapeutic results were improved: a complete tumor regression rate determined by x-ray was 26.7%, a 2-year survival rate 19.2%. In the group of patients who were irradiated by the commonly used methods, the same values were lower. Improved tolerance of therapy with fractionation of a common daily dose was noted.
