Statistics and Outcomes

At Seattle Children’s Cancer and Blood Disorders Center, our outcomes significantly exceed the national average for a wide range of cancers.

  • “Outcomes” refer to the results of treatment and evaluate how effective care is. We also provide statistics such as the number of stem cell transplants performed and patients seen (volumes). 
    We gather this data to:  

    • Measure the health of our patients 
    • Improve the quality of the care we provide 
    • Help you make informed decisions about your child’s care
