What this research studies
Researchers will study cells taken from children's cystic lymphatic malformations using gene, microRNA, and protein analyses to understand what drives growth and spread. They will use those lab findings to test targeted drug combinations and other therapies in cell and laboratory models to find options that work better than current treatments. The team is focusing on mutations like PIK3CA and pathways that make some patients resistant to existing PI3K/mTOR drugs. The goal is to match treatments to each child’s lesion to reduce infections, inflammation, and the number of surgeries needed.
Who could benefit from this research
Good fit: Children from newborns through 11 years old with cystic lymphatic malformations—especially those with neck masses, recurrent infections, or known PIK3CA pathway changes—are the most likely candidates.
Not a fit: Adults or patients whose malformations do not involve PI3K/PIK3CA pathway abnormalities may not receive direct benefit from this project.
Why it matters
Potential benefit: Could lead to personalized medicines that shrink malformations, reduce infections and inflammation, and lessen the need for repeated surgeries and harsh drugs.
How similar studies have performed: Some patients have experienced size reductions with PI3K/mTOR inhibitors, but many do not respond and none are cured, so this work builds on partial successes to find better, individualized options.
