While the cure rate for Leukemia is high -- not all patients respond equally to the drugs used to treat the disease.
Researchers conducted genetic studies using nearly 500 pediatric patients. They were able to identify over 100 genes that influenced how many cancer cells were left after treatment.
Twenty-one genes were linked to relapse; another 21 genes were associated with a greater response to chemotherapy.
They hope to use this information to prescribe effective chemotherapy regimens for each patient.
