Background
While most types of childhood leukemia are routinely cured with therapy, juvenile myelomonocytic leukemia (JMML), a type of blood cancer that affects young children remains exceedingly difficult to treat. Even when cured, the infants and toddlers affected by this disorder have difficulty tolerating the required treatment, which can be very intense. Equally frustrating, it is challenging to predict who will respond to the treatments we currently have versus those that will require experimental therapy in order to cure them of their cancer.
