Convection-enhanced delivery (CED) of therapeutic agents is a promising local delivery technique that has been extensively studied as a treatment for CNS diseases over the last 2 decades. Applying this technique to treat brain tumors, we have been working to develop novel local chemotherapy against brain tumors. In the meanwhile, clinical trial against diffuse intrinsic brain tumor aiming at Japanese “shonin” approval is recruiting patients. In this study, potential of local CED based chemotherapy against supratentorial brain tumor is discussed.
