Predictive Biomarkers Of Cellular Radiosensitivity For Clinical Radiotherapy Treatment, Lisa White

Doctoral

Radiotherapy is prescribed to more than 50% of cancer patients during their treatment schedule. Due to intrinsic factors, individual variation in response exists, which will result in side effects or toxicity in a number of patients. Therefore, development of an assay or biomarker for the prediction and assessment of radiosensitivity among cancer patients undergoing radiotherapy would be beneficial. Such an assay would limit toxicities and facilitate dose-escalation for those patients who require it. Assays for predicting intrinsic cellular radiosensitivity remains as the established G2 chromosomal radiosensitivity and most promising, γH2AX foci assay. They can be applied to blood samples from …
