About the National Childhood Cancer Registry

The National Childhood Cancer Registry (NCCR) was developed under the NCI Childhood Cancer Data Initiative (CCDI) to leverage the nation's existing, primarily adult, cancer registries to identify and follow childhood cancer cases in the United States.

Special Features

Annual Percent Change and Confidence Intervals available

Rates and trends in NCCR*Explorer are presented with the Annual Percent Change (APCs) and confidence intervals (CI). They are available on the Graph view when you hover over a data point, in the Data Table, and in the data download in CSV format.

Unique age groupings for children and adolescents & young adults

Population-based cancer data sources typically utilize 5-year age groupings which is sufficient to display the profound differences in rates over the life span. Data may also be displayed by some larger age aggregations for comparisons of rates for children/young adults as well as the older ages in which overall rates are much higher.

However, for the age 0-39 population, cancer data are much different than for older adults. For this reason, some selectable age groupings have overlapping ranges.

International Classification of Childhood Cancer disease classification with subtypes

The International Classification of Childhood Cancer (ICCC) is a system for classifying childhood cancer developed by the World Health Organization (WHO). It categorizes childhood cancer based on the type of tissue affected (also called histology or morphology) and body location as well as similar clinical management and outcomes. This is different from the system used for adult cancer, which is primarily based on the location or organ affected. The current version of ICCC can be found here: ICCC Recode Third Edition ICD-O-3/IARC 2017.
