From: Letrozole sensitizes breast cancer cells to ionizing radiation
Potentiation of radiation-induced growth inhibition by letrozole measured by the MTT assay. Growth of MCF-7CA cells, measured 6 days after treatment, was inhibited to a 40% greater extent with letrozole plus 2 Gy radiation, and to a 76% greater extent with letrozole plus 4 Gy radiation, compared with radiation alone.
