Description:
Detailed site-specific codes for the clinical N category suffix as defined by AJCC.
Clinical, pathological, and postneoadjuvant therapy 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.
