National Cancer Data Base - Data Dictionary PUF 2014

Summary of PUF User File Changes and Previous Versions of the Data Dictionary

With every new release of the PUF, a summary of changes from the previous version of the PUF is compiled. This information is especially useful for those who have previously received a PUF, as item definitions and availability, along with other documentation, may change with a new release.

Below are links to archived versions of previous PUF data dictionaries. If you are analyzing data from the 2011, 2012, or 2013 PUFs, please refer to these links, particularly the item definitions, diagnosis years available, and SAS, SPSS, and STATA syntax, as those may have undergone changes for the 2014 PUF that are not relevant to your version of the PUF.

If you have any questions, please contact PUF staff at
