Important concepts

Important Concepts

  • Pediatric Oncology Partnerships have led to dramatic gains against childhood cancer: (age <15 yrs: survival 80%)

  • 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

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 world goal

Pediatric Oncology WorldGoal

  • Improve the survival rates for childhood cancer

  • Reduce the immediate and long-term side effects causing deficits/disabilities:

    cognitive musculoskeletal pulmonary fibrosiscardiomyopathy renal insufficiencyinfertility

    Endocrinopathiessecond cancers

    vision losshearing loss


Specific types of childhood cancer

Specific types of childhood cancer

Hematologic: acute leukemias-33%

lymphomas-12%

Solid tumors: brain tumors-20%

muscle or bone tumors-12%

Solid Tumors in children < 8yrs: 16% retinoblastoma, Wilm’s tumor, neuroblastoma, hepatoblastoma

The children s oncology group

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

7 Chicagoland COG programs:

UIC + Rush (+ Stroger);

CMH, U of C, Loyola, Lutheran General, Christ


Children s oncology group clinical trials research program

Children’s Oncology Group Clinical Trials Research Program

Goal: improve survival & decrease toxic side effects by

comparing new experimental therapy to current standard of care

150 clinical trials currently available

Each trial enrolls: 30-2000 patients

Trials frequently randomize patients between 2-4 different arms

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 group clinical trials research program succeeds because of

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

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?
