NAACCR XML: Tumor.derivedSeerPathStgGrp

Description
This data item is needed to store the results of the derived algorithmic calculation of Derived SEER Pathologic Stage Group.
Rationale
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.
