childhood brain cancer
Posted on by Dr. Francis Collins
Every year in the United States, several hundred children and their families receive a devastating diagnosis: diffuse intrinsic pontine glioma (DIPG). Sadly, this inoperable tumor of the brain stem, little known by the public, is almost always fatal, and efforts to develop life-saving treatments have been hampered by a lack of molecular data to identify agents that might specifically target DIPG. In fact, more than 200 clinical trials of potential drugs have been conducted in DIPG patients without any success.
Now, using cell lines and mouse models created with tumor tissue donated by 16 DIPG patients, an international research coalition has gained a deeper understanding of this childhood brain cancer at the molecular level. These new preclinical tools have also opened the door to identifying more precise targets for DIPG therapy, including the exciting possibility of using a drug already approved for another type of cancer.
