Web8 de mar. de 2024 · The radiotherapy community has for decades been striving for an easy-to-use assay to measure the radiosensitivity of an individual patient's tumour. Initially these approaches centred around developing short-term cultures [1]. In these cultures, radiosensitivity was defined as the fraction of cells surviving 2 Gy radiation dose (SF2). WebRadiosensitivity. Radiosensitivity is the response of the tumor to irradiation that can be measured by the extent of regression, rapidity of response, and response durability.
