        Description
            This data item is needed to store the results of the derived algorithmic calculation of SEER Combined Stage Group. 
        Rationale
                Rationale for change proposal (potential benefits of change): The SEER Program is developing an algorithm to calculate clinical and pathologic stage group based on their T, N, and M components and additional information as needed to calculate stage. For example, for thyroid, additional information is needed on histology and age to calculate stage. Once the T, N, and M are known an algorithm can assign the stage group instead of a registrar having to look up the stage. There are also provisions for a separate field for directly assigned stage group if the registrar prefers entering it.
