Using nanoparticles administered directly into the cerebrospinal fluid (CSF), a research team has developed a treatment that may overcome significant challenges in treating a particularly deadly brain cancer.
The researchers, led by professors Mark Saltzman and Ranjit Bindra, administered to mice with medulloblastoma a treatment that features specially designed drug-carrying nanoparticles. The study, published in Science Translational Medicine, showed that mice who received this treatment lived significantly longer than mice in the control group.
Medulloblastoma, a brain cancer that predominantly affects children, often begins with a tumor deep inside the brain. The cancer is prone to spread along two protective membranes known as the leptomeninges throughout the central nervous system, particularly the surface of the brain and the CSF.
