CS Mets Eval

PUF Data Item Name: 
NAACCR Item #: 
Records how the code for CS Mets at DX was determined based on the diagnostic methods employed.
Analytic Note: 

CS Mets Eval is part of the Collaborative Stage Data Collection System (CS), and was implemented in 2004.  It describes whether the staging basis for CS Mets at Dx was clinical or pathologic, and whether any systemic treatment was given prior to that code assignment.
Some detective work is required to interpret codes in CS Mets Eval.  The codes may differ by type of cancer and by the version of CS in which the case was coded.  In the PUF, CS fields are retained in the form in which they are submitted.  That means that it will be necessary to identify the CS Version Numbers that are used in the PUF file, and use those to identify whether the contents of the CS Mets Eval field may have changed over time.  Links to the site-specific codes can be found at
