er069 Laterality

0

Not a paired site

3

Unilateral, NOS

4

Bilateral involvement at time of diagnosis, lateral origin unknown for a single primary; or both ovaries involved simultaneously, single histology; bilateral

retinoblastomas; bilateral Wilms tumors

9

Paired site, but no information concerning laterality

SOURCE

If the transmitted value is numeric, then just load it with no conversion.

Otherwise, convert it to 9.

If TU_Site is an unpaired site and TU_Laterality is not 0, then automatically set TU_Laterality to 0.

 

*Paired sites are referenced under Site.

Manual Change

Manual Change Only

CONSOLIDATED DATA EXTRACT

Yes

Due to differences between SEER and the CCR (SEER wants 5 coded only for cases dx 2010 or later), for cases dx prior to 2010 convert the 5 to 9.

HISTORICAL CHANGES

2/01/06

Removed Update logic that conflicted with IF #326 which now requires a laterality code of 0 for non-paired sites. Conversion of database performed.

2/2009

Added IF #823.

2010

2010 Data Changes:  Added 5 to Allowable values. Code 9 no longer records midline tumor information and is used only when there is no laterality information for a paired site. Code 5 may be used to record a midline tumor of a paired site for any year of diagnosis, but review or recoding of historic cases is not required. For analysis using data with diagnoses before January 1, 2010, code 5 should be grouped with code 9.  Revised Update logic to consider analytic class of case before performing update and removed the update that would take a laterality 4 over a 1 or 2 so these cases will be manually reviewed.

5/11/11

2011 Data changes: Added extract note for converting 5 to 9 for pre-2010 cases. Added new interfield edits IF9154 and IF966.
