In the United States, about 65,980 new cases of non-Hodgkin
lymphoma (including adults and children) will be diagnosed in 2009.
About 460 of these will be in children under age 15.
About 4.3% of childhood cancers are non-Hodgkin lymphomas.
About 70% of non-Hodgkin lymphoma occurs in boys, and it is
about 40% more common in white children than black children. The
reasons for these gender and racial differences are not known. The
number of children with non-Hodgkin lymphoma increases with age.
The 5-year survival rate for children and adolescents younger
than age 20 with non-Hodgkin lymphoma ranges from around 70% for
anaplastic lymphoma to around 85% to 90% for the others. The 5-year
survival rate refers to the percentage of patients who live at least 5
years after their cancer is diagnosed. Five-year rates are used to
produce a standard way of discussing prognosis (outlook for recovery
and survival). Of course, many people live much longer than 5 years.
Five-year survival rates are based on patients diagnosed and initially
treated more than 5 years ago. Improvements in treatment often result
in a more favorable outlook for recently diagnosed patients.
