Chronic oxidative stress and radiation-induced late normal tissue injury: a review

Int J Radiat Biol. 2004 Apr;80(4):251-9. doi: 10.1080/09553000410001692726.

Abstract

Purpose: It is proposed that the development and progression of radiation-induced late effects are driven, in part, by chronic oxidative stress. This mini-review presents data to support this hypothesis and provides the foundation for antioxidant-based interventional approaches directed at modulating late normal tissue injury.

Conclusions: Although a causal link between chronic oxidative stress and radiation-induced late normal tissue injury remains to be established, a growing body of evidence appears to support the hypothesis that chronic oxidative stress might serve to drive the progression of radiation-induced late effects. The similarity between chronic tissue injury, chronic inflammation and fibrosis observed in a variety of disease states, including radiation late effects, is provocative and offers the opportunity to apply antioxidant-based therapies to mitigate and/or treat late radiation-induced normal tissue injury.
