Overview
About one to two percent of children with leukemia have juvenile myelomonocytic leukemia (JMML). It mainly affects children younger than four years old.
JMML is a very hard type of leukemia to treat. The current treatment includes chemotherapy and a bone-marrow (hematopoietic stem cell) transplant.
The medical team at Seattle Children's, an SCCA parent organization, has a long history of successfully caring for children who have leukemia.

If your child's condition requires a bone marrow transplant, you should know that the Fred Hutchinson Transplant program at SCCA was ranked first in outcomes in a four-year study by the National Marrow Donor Program (NMDP) that measured one-year survival rates of patients among 122 transplant centers in the United States. The Hutchinson Center pioneered the use of bone marrow transplants as a treatment for blood diseases over 40 years ago. Since then thousands of patients with leukemia have come from around the world to receive bone marrow transplants at SCCA. Bone marrow transplants have transformed leukemia and related cancers, once thought incurable, into highly treatable diseases with survival rates as high as 80 percent.
