Abstract

Individual radiosensitivity has a crucial impact on radiotherapy related side effects. Our aim was to study a breast cancer collective for its variation of individual radiosensitivity depending on the patients’ age. Peripheral blood samples were obtained from 129 individuals. Individual radiosensitivity in 67 breast cancer patients and 62 healthy individuals was estimated by 3-color fluorescence in situ hybridization. Breast cancer patients were distinctly more radiosensitive compared to healthy controls. A subgroup of 9 rather radiosensitive and 9 rather radio-resistant patients was identified. A subgroup of patients aged between 40 and 50 was distinctly more radiosensitive than younger or older patients. In the breast cancer collective a distinct resistant and sensitive subgroup is identified, which could be subject for treatment adjustment. Especially in the range of age 40 to 50 patients with an increased radiosensitivity are more frequently and may have an increased risk to suffer from therapy related side effects.
