Collaborative Stage

This table shows the allowable values for the generated Collaborative Stage data items. The Storage Code is the value to be stored in the field of a NAACCR record. The Storage Codes are designed for analysis. The Display String is the corresponding label that should be displayed on the screen or in a report. The meaning of these strings will be clear to the registrar or physician user.
Note: A blank may indicate either that the calculation was not performed or that the calculation resulted in an error.
