Survival statistics for childhood non-Hodgkin lymphoma

Survival statistics for childhood non-Hodgkin lymphoma (NHL) are very general estimates and must be interpreted very carefully. These statistics are based on the experience of groups of children and cannot be used to predict a particular child’s chances of survival.

There are many different ways to measure and report cancer survival statistics. Your child’s doctor can explain the statistics for childhood NHL and what they mean for your child.

Observed survival is also called overall survival. It is the percentage of children with a certain type of cancer who are expected to live for at least a specified period of time after their diagnosis. Doctors often use the observed survival rate when they talk about a prognosis.

The 5-year observed survival for NHL in children 0 to 14 years of age is 89%. This means that, on average, 89% of children diagnosed with NHL are expected to live at least 5 years after their diagnosis.

Observed survival does not consider the cause of death. But of the 11% of children who don’t survive 5 years, most die from the cancer rather than from other causes.

Survival varies with each type of childhood NHL as well as by stage.

Generally, the earlier childhood NHL is diagnosed and treated, the better the outcome.

There are no specific Canadian statistics available for the different types and stages of NHL in children. The following information comes from a variety of sources. It may include statistics from other countries that are likely to have similar outcomes as in Canada.

Talk to your child’s doctor about their prognosis. A prognosis depends on many factors, including:

• the child’s health history
• the type of cancer
• the stage
• certain characteristics of the cancer
• the treatments chosen
• how the cancer responds to treatment

Only a doctor familiar with these factors can put all of this information together with survival statistics to arrive at a prognosis.
