PURPOSE: There is growing interest in developing individually tailored cancer radiation therapy (RT), wherein patients with high intrinsic radiosensitivity are identified before commencing treatment, to minimize severe adverse reactions. In a previous retrospective study of severely radiosensitive RT patients, we established a functional assay with a high predictive capability. The assay involves ex vivo irradiation of peripheral blood mononuclear cells and analysis of DNA repair using the γ-H2AX assay. It is unknown whether RS is a fixed phenomenon or is modulated under different conditions. We now report the impact of RT on the apparent radiosensitivity, as reflected by the assay.
