Radiation resistance assay for predicting treatment response and clinical outcome

摘要

The present invention provides a novel method for assaying radiation resistance of cancer cells by isolating cancer cells, irradiating the cells, incubating the cells with a labeled marker indicative of cell proliferation, measuring the amount of labeled marker incorporated into the cells in order to determine the effect of radiation on the proliferation of cells, and then determining the relative resistance of the cells to radiation. Also provided are methods of assaying radiation resistance of cancer cells which are exposed to radiation and radio-sensitizing or chemotherapeutic agents.
