Murray, J; Griffin, C; Gulliford, S; Syndikus, I; Staffurth, J; et al. (ELSEVIER IRELAND LTD, 2020-01-01)BACKGROUND AND PURPOSE: Image-guided radiotherapy (IGRT) improves treatment set-up accuracy and provides the opportunity to reduce target volume margins.

This study aimed to identify anatomically-localized regions ... -
Individual patient data meta-analysis shows a significant association between the ATM rs1801516 SNP and toxicity after radiotherapy in 5456 breast and prostate cancer patients.
Andreassen, CN; Rosenstein, BS; Kerns, SL; Ostrer, H; De Ruysscher, D; et al. (ELSEVIER IRELAND LTD, 2016-12-01)PURPOSE: Several small studies have indicated that the ATM rs1801516 SNP is associated with risk of normal tissue toxicity after radiotherapy.
