The Cancer Search Bar: Most Searched Pediatric Leukemia Questions

A persistent fever. Bruises or tiny red dots on the skin. A child who seems unusually pale or worn out. These subtle, easy-to-dismiss symptoms are sometimes the first signs of leukemia in children, according to Dr. Andrew Silverman of the Pediatric Hematology Oncology Group at Jersey Shore University Medical Center.

In a new video Q&A with CURE, Dr. Silverman explains that childhood leukemia often mimics common viral illnesses, with one key difference: it doesn't improve or wax and wane the way a typical infection does. Fevers, bruising, petechiae, pallor, shortness of breath during activity, and unusual fatigue that lingers are the signs that often prompt a trip to the pediatrician — and, eventually, routine bloodwork that reveals the diagnosis.

There is encouraging news on outcomes. Survival rates for childhood leukemia, once around 90% at five years, have climbed to more than 95% for most patients thanks to recent advances in treatment.

What causes it, though, often remains a mystery. Silverman notes that most cases can't be traced to a specific behavior or exposure; some children have known risk factors, such as Down syndrome, but for many families, there's no clear explanation.

Treatment length depends on the type of leukemia. Acute myelogenous leukemia (AML) requires aggressive therapy over roughly six months, much of it spent in the hospital. Acute lymphoblastic leukemia (ALL), whether T-cell or B-cell, typically spans about two and a half years — an intensive first six to nine months followed by a longer maintenance phase of oral medication that allows children to return to school and everyday life.

Relapse is possible but uncommon; most children treated for leukemia do not see it return. For those who do, Silverman says, additional treatment options exist to pursue remission and long-term survival again.
