NAACCR XML: Tumor.tnmClinDescriptor


Alternate Names

   Clinical Stage (Prefix/Suffix) Descriptor (CoC)


Description
Identifies the AJCC clinical stage (prefix/suffix) descriptor as recorded by the physician. AJCC stage descriptors identify special cases that need separate data analysis. The descriptors are adjuncts to and do not change the stage group.

Pathologic and clinical stage data are given three separate areas in the NAACCR Data Exchange Record Layout. CoC defines a descriptor and “Staged By” item for each of these three areas.

Rationale
CoC requires that AJCC TNM staging be used in its approved cancer programs. AJCC developed its staging system for evaluating trends in the treatment and control of cancer. This staging is used by physicians to estimate prognosis, to plan treatment, to evaluate new types of therapy, to analyze outcome, to design follow-up strategies, and to assess early detection results.
