NAACCR XML: Tumor.tnmClinStageGroup

Alternate Names
   Clinical Stage Group (CoC)
Description
Detailed site-specific codes for the clinical stage group as defined by AJCC and recorded by the physician.

Pathologic and clinical stage data are given three separate areas in the NAACCR Data Exchange Record Layout.
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.
Codes (in addition to those published in the AJCC Cancer Staging Manual)
88 Not applicable, no code assigned for this case in the current AJCC Staging Manual.
99 Unknown, not staged
Note: See the AJCC Cancer Staging Manual, current edition for site-specific categories for the TNM elements and stage groups. See the STORE manual for specifications for codes and data entry rules.
