[Possibilities of quantitative criteria of the effectiveness of treatment of glial brain tumors].

The authors suggest a quantitative criterion for evaluating the efficacy of radiotherapy in patients with glial tumors of the brain. Three types of course followed by the disease are distinguished: regressive, progressive, and undulating. The use of the quantitative criterion made it possible to detect patients with individual increased sensitivity to macrofractional radiotherapy and to come to the decision on the expediency of conducting the next series of irradiation in each concrete case.
