Video Summary
Dr. Zvankin presents a study on enhancing the efficacy of convection-enhanced delivery (CED) in diffuse intrinsic pontine glioma (DIPG). DIPG is a highly infiltrative and inoperable brain tumor that is difficult to treat due to the blood-brain barrier and ABC transporters. The study focuses on using dasatinib, an inhibitor of the PDGF receptor, and teriquidar, an ABC transporter inhibitor, to improve drug-tumor interaction. In vitro and animal models demonstrated increased cell viability and survival rates with dasatinib and teriquidar treatments. Pre-treatment with ABC transporter inhibitor and dexamethasone in CED showed improved drug dispersion, increased apoptosis, and extended survival in DIPG-bearing mice.
