LOINC long common name : Descriptor.clinical Cancer Narrative;
LOINC short name : Descript.clinical Cancer;
LOINC 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, clinical,
and other 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.
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... NAACCR Data Standards and Data Dictionary Version 11;
