The authors' experience with intraoperative radiotherapy (IORT) in 129 patients with a tumorous process at various sites has demonstrated that in most clinical events, single radiation doses of 10-20 Gy is insufficient to have a persistent local effect and requires additional pre- or postoperative remote irradiation. The use of IORT as a single component of radiation exposure does not lead to significant radiation damages to normal tissues. When IORT is combined with remote irradiation (the latter using doses of 30-60 Gy), 30% of patients develop radiation-induced normal tissue lesions.

Research in radiobiology should be aimed at the design of nonstandard dose fractionation, introduction of various modifiers and their combinations, prediction of individual responses of the tumor to ionizing radiation. First-hand clinical data on 3000 cases support the promise of such approach.

The first direction includes scientifically substantiated regimens of non-classic dose fractionation, various radiomodifiers and their combinations, and individual prognosis of a tumor response to ionizing radiation. This direction based on 3000 cases, holds promise.
