Description:

Detailed site-specific codes for the post therapy clinical (yc) tumor (T) 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.

Evaluates the primary tumor (T) and reflects the tumor size and/or extension of the tumor known following the completion of neoadjuvant therapy (satisfying the definition for that disease site) before planned surgical resection or primary treatment consisting of systemic and/or radiation therapy.
