Prevention of radiation damage

The development and implementation of precision methods for pre-radiation topodosimetric preparation has significantly reduced the frequency of radiation injuries. The use of the VDF and NSD factors made adjustments to the planning of bioequivalent radiation regimes. Despite this, radiation complications remain a frequent limiting factor in radiation therapy. Recent studies have shown that the development and formation of radiation damage seems to be a complex and diverse process, not all aspects of which have been sufficiently studied. In the overwhelming number of patients who have undergone radiation therapy, there is a decrease in immunity parameters [12]. In the development of radiation injuries, the infection of the radiation zone [17], the prevalence of the malignant process [4], and regional circulatory disorders [6] are of direct importance. The conditions that predispose to the occurrence of radiation damage are trauma and inflammation. The frequency of radiation damage increases with the use of various types of chemotherapy, especially in combination with radiation therapy and hyperthermia [10]. The listed factors, which determine the development of distant radiation damage, create a prerequisite for the development of measures that protect the healthy tissues surrounding the tumor [8].
