Very Rare Malignant Tumors Program

Children with very rare malignant tumors will find unparalleled expertise in the multidisciplinary team at the Very Rare Malignant Tumors Program at Children's Hospital of Philadelphia (CHOP). These tumors come in different forms and are individually very rare, but as an aggregate, they comprise more than 10% of all pediatric cancers. Our program will give these patients a pediatric medical home and also drive discoveries in these often under-researched types of cancers.
