ABSTRACT

The paper is concerned with the results of radiotherapy of inoperable lung cancer patients. The efficacy of dynamic and conventional fractionation regimens was evaluated in relation to the tumor growth rate and size. The tumor growth rate was shown to be of importance for a local radiation effect the higher growth rate was, the more pronounced tumor lesion and resorption were.
