The first international gliomatosis cerebri conference was held at the Institut Curie in Paris, France on March 26th and 27th. The conference brought together the top physicians and researchers in the world. Experts from Weill Cornell, Dana-Farber, Memorial Sloan-Kettering, Johns Hopkins, and St. Jude’s gathered along with the families devastated by GC. We united to build a foundation for collaboration and to advance the research for GC. Such a successful meeting filled with positivity, progress, and much hope!
