Developing new therapies for infants, children, adolescents and young adults with cancer requires a well-trained, dedicated multidisciplinary team. Physicians and scientists at The Children's Hospital of Philadelphia Division of Oncology and Center for Childhood Cancer Research are collaborating to develop new therapies for cancer. We are dedicated to improving our understanding of the biology and genomics of childhood cancer, developing better preclinical models, evaluating new drugs, and improving the efficiency and conduct of clinical trials.
