NPCR

DESCRIPTION

This item is needed to store the results of NPCR’s derived algorithmic calculation of clinical stage group based on AJCC T, N, and M and relevant biomarkers and prognostic factors. At this time the algorithm derives AJCC 7th ed. Stage group only; however, updates to future AJCC editions are anticipated. The purpose of the derived stage fields is to segregate the data values for AJCC clinical and pathological stage groups derived from the NPCR algorithm from the values directly entered from the medical record or by the registrar.
