Description:
Detailed site-specific codes for the postneoadjuvant therapy Path N category suffix as defined by AJCC.
Clinical, pathological, and post therapy yc and yp stage data are given four 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.
