Pediatric Oncology Research:The Impact of Collaborative Clinical Trials Mary Lou Schmidt, MD Head, Division of Pediatric Hematology/OncologyDepartment of PediatricsUniversity of Illinois at Chicago College of Medicine
Important Concepts • Pediatric Oncology Partnerships have led to dramatic gains against childhood cancer • 2/3 of survivors of childhood cancer have a major disability by 25 years of age • 15-45 year olds have had NO improvement in their survival from cancer in the last 30 years.
Childhood Cancer’s Impact The leading cause of death by disease for children < 15 years of age (greater than HIV, heart disease, cystic fibrosis, infection combined) 12,000 US cases/year, 160,000 cases worldwide 20% death rate in Western World (1 in 5 die) 65% of survivors have a major disability 25% of survivors have 3-4 disabilities/one of which is life-threatening
Pediatric Oncology WorldGoal • Improve the survival rates for childhood cancer • Reduce the immediate and long-term side effects including: second cancers, cognitive deficits, musculoskeletal abnormalities, major organ dysfunction (lungs, heart, kidneys, liver, etc.), infertility
Specific types of childhood cancer Hematologic: acute leukemias-33% lymphomas-12% Solid tumors: brain tumors-20% muscle or bone tumors-12% Solid Tumors that affect children < 8: 16% retinoblastoma, Wilm’s tumor, neuroblastoma

The Children’s Oncology Group 250 institutions: US, Australia, Canada, Switzerland, the Netherlands and New Zealand including: St. Jude, Sloan-Kettering, Mayo Clinic, Harvard, Stanford, MD Anderson + 240 other leading academic medical centers 7 Chicagoland COG programs: UIC + Rush (+ Stroger); CMH, U of C, Loyola, Lutheran General, Christ
Children’s Oncology Group Clinical Trials Research Program Goal: improve survival and decrease toxic side effects by comparing new experimental therapy to current standard of care 150 clinical trials currently available for different diseases and patients Each trial includes: 30-2000 patients Trials frequently randomize patients between 2-4 different plans Each trial must be locally approved and managed, With high quality data entered on time and on-line, And institutional audits passed every 3 years Results are published collaboratively
Children’s Oncology GroupClinical Trials Research Program Succeeds because of Full participation by all US Pediatric Oncologists in a Collaborative Spirit, using scarce shared resources which has led to amazing forward progress Fueling further research & education
When is a kid a kid? • Why have children begun to survive at much higher rates than adults? • Why have patients ages 15-45 had NO improvement in their survival in 30 years? • How can we improve the survival rate for adolescents and young adults?

Impact of support • Push all facets of research forward by improving enrollment on all possible Children's Oncology Group clinical trials at each local institution • Specifically focus on adolescents and young adults • Educate the public and community-based practitioners to refer adolescents and young adults to the COG centers
Funding for COG Clinical Trials National Institutes of Health $$$ COG: CureSearch website, tissue banks and research labs, the 150 COG clinical trials publish clinical trials results auditing 250 COG institutions Estimated actual cost to the local COG institution: $ 7000/patient enrolled Each COG hospital/institution receives: ____________________________ $ 2400/patient enrolled Local Institutional Funding Gap Coverage: who pays? The treating institution or philanthropists
Requirements for maximum participation in COG Clinical Trials • Salary support for: Principal Investigator/MD’s Clinical Research Nurses Regulatory Researchers Community educator to improve referrals • Travel Funds to COG meetings • Supplies-computers, specimen submissions
Immediate Impact on Childhood and Adolescent/Young Adult Cancer • Open the broadest pallet of COG clinical trials possible and fully participate in all aspects of COG • Enroll, enroll, enroll all possible patients • Collaborate, collaborate, collaborate
