There’s an old adage that says if you want to go fast, go alone; if you want to go far, go together. Research science rarely adheres to that—investigators spend a lot of lonely hours peering into microscopes and scrolling through endless data points, all in the hope that someday all that solo work will add up to a breakthrough. We often go alone, and go far, but usually not fast.
The Children’s Brain Tumor Project has also defied that adage in that we are going fast, but together. This requires teamwork like no other—we need other labs at Weill Cornell, tissue banks around the country, and other scientists comparing notes and sharing findings—because we know we need to move quickly, and get far.

Thanks to a number of grants and private donations, in July and August the CBTP lab team was joined by several young researchers working on specific projects to advance the field of pediatric neuro-oncology. This “summer sprint” was an unprecedented effort that produced some excellent results.
Umberto Tosi, funded by a POST grant from the Alex’s Lemonade Stand Foundation, worked on a project to improve the measurement of drug delivery to the brain via “theranostic” (therapeutic and diagnostic) agents.
The usual method of determining whether a drug has been successfully delivered is to wait for a clinical response, a “wait-and-see” approach that is neither timely nor precise. If researchers could modify a drug to make it fluorescent—and therefore visible on PET or MRI imaging—they would be able to see in real time whether that drug has reached its target. The key is to make delivery of the drug visible and measurable without reducing its effectiveness. Read more
As many of you probably read about on Facebook, on September 8 we treated the final patient in our Phase I clinical trial of convection-enhanced delivery (CED) for diffuse intrinsic pontine glioma (DIPG). The trial, which had enrolled 27 patients over the past four years, was designed to test the safety of CED as a means of delivering a cancer-fighting drug directly to the site of a DIPG tumor. Four patients received a second infusion, bringing the total number of treatments to 31. Read more

This summer is going to be an amazing one in the Children’s Brain Tumor Project laboratory. Thanks to grants and gifts from families and foundations, we will have six summer researchers conducting several different lines of investigations, which will give our research a tremendous boost.
One thing we’ve known from the beginning of our research on pediatric brain tumors is that none of us will be able to do this alone. We must work too fast, and find answers too quickly, to operate in silos. The old model, in which researchers guard their work carefully until they publish results, simply won’t work. Read more
Thanks to the generosity of a number of donors, the summer of 2016 will be an unprecedented one at the Children’s Brain Tumor Project (CBTP). With grants and gifts from families and foundations, the CBTP plans to fill the lab with an impressive array of summer students and fellows conducting research at an amazing pace. The newly funded summer positions are:
St. Baldrick’s Summer Fellows: Emilie George and Raymond Chang will be testing new drugs and drug combinations against gliomatosis cerebri and DIPG, funded by a summer fellowship grant from the St. Baldrick’s Foundation. (More about that grant)
It will be four years in May since Dr. Souweidane treated the very first patient in his clinical trial testing the safety of convection-enhanced delivery (CED) of 124I-8H9 against DIPG. (The 8H9 antibody has been shown to bind to the tumor, and 124I kills cancer cells with radiation.) The trial was originally expected to last for two years and treat12 DIPG patients at four dose levels; in 2014 the FDA approved an extension of the trial to seven dose levels. Dr. Souweidane is currently treating patients at the seventh dose level, and has re-treated several children. There have been no adverse effects on any child. Read more
I am very proud to be working in the Children’s Brain Tumor Project laboratory, and quite astounded at how fast the initiative has grown. I was appointed as a Fellow in 2012, when I was assigned to work on the role of bone-marrow-derived cells in low-grade glioma transformation. Today, I’m honored to lead the daily operation of our lab’s partnership with the Weill Cornell Institute for Precision Medicine (IPM), which allows us to do exactly the sort of personalized medicine that we dreamed about just a few years ago.
Shortly after our summer issue went to press, Dr. Greenfield and CBTP researchers published a 15-year review of gliomatosis cerebri cases in the Journal of Child Neurology. The paper examined the cases of 10 children seen at Weill Cornell or enrolled in our GC International Registry, alongside 89 children diagnosed with GC reported in the literature between 2000 and 2014. The review documents the kinds of molecular changes seen in gliomatosis cerebri and paves the way for future research. Retrospective reviews like these are invaluable to the research community, as they painstakingly gather data that others can use to initiate new lines of investigation.
