SEER Incidence Site Recode
The values of SEER site recode variables are based on the primary site and histology data fields submitted to SEER by the registries. The site recode variables define the major cancer sites that are commonly used in the reporting of cancer incidence data. For example, there is a section of the SEER Cancer Statistics Review for each major site corresponding to groupings in a site recode variable. The site recode variables are added to the SEER databases as a convenience for researchers.
The table below contains definitions for the available site recode variables. Follow the links to view the values of primary site and histology for each grouping. Each definition shows the coding for an additional Site Recode in which mesothelioma and Kaposi sarcoma are separate categories.
The ICD-O-2 (1/27/2003) and ICD-O-3 (1/27/2003) definitions apply to cases coded in ICD-O-2 and ICD-O-3, respectively. These current definitions of site recode include the same set of site groups and are comparable to one another. If all histologies for all years have been converted to ICD-O-3, use only the ICD-O-3 (1/27/2003) recode. If not, use the ICD-O-3 (1/27/2003) recode for cases in ICD-O-3 and the ICD-O-2 (1/27/2003) recode for cases in ICD-O-2. Do not continue to use the ICD-O-2 (4/15/2002) recode except for historic analysis of ICD-O-2 cases only. Any comparisons between recodes dated 1/27/2003 and 4/15/2002 are invalid.
