Tumor immune remodeling by TGFβ inhibition improves the efficacy of radiation therapy

The tumor immune environment has been linked to prognosis in patients with a range of malignancies. Recently, we demonstrated in pre-clinical models that modifying the tumor immune environment using a small-molecule inhibitor of TGFb significantly improved outcome to subsequent radiation therapy. These data suggest that this and other immunotherapies may be used to remodel the tumor before conventional cancer therapies to improve outcomes.
