Detailed site-specific codes for the postneoadjuvant therapy Path stage group 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.

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.

Identifies the remaining anatomic extent of disease based on the T and N following the completion of neoadjuvant therapy (satisfying the definition for that disease site) and planned postneoadjuvant therapy surgical resection, and the M status defined during the diagnostic workup.
