Localized/Regional/Distant Stage Adjustments
For 1973-2008 SEER Research Data (November 2010 submission)

The SEER Program strives to make all L/R/D stage variables consistent for all cancer sites for the appropriate years. However, there are certain site/year combinations where this is not possible. The following table details changes imposed on the stage variables by the SEER Program.

Any cases diagnosed in years not covered by the year range indicated in parentheses within the stage variable name are coded as Blank. Cancer sites without notations for a stage variable are fully staged within the year ranges covered by the variable.
