CS Tumor Size/Extension Evaluation

CS Tumor Size/Ext-Eval records how the codes for the two items "CS Tumor Size" and "CS Extension" were determined and the diagnostic methods employed.

Code Description & Staging Basis
0 No surgical resection done. Evaluation based on physical examination, imaging examination, or other non-invasive clinical evidence. No autopsy evidence used. C
1 No surgical resection done. Evaluation based on endoscopic examination, diagnostic biopsy, including fine needle aspiration biopsy, or other invasive techniques. No autopsy evidence used.
2 No surgical resection done, but evidence derived from autopsy (tumor was suspected or diagnosed prior to autopsy). P
3 Surgical resection performed without pre-surgical systemic treatment or radiation OR surgical resection performed, unknown if pre-surgical systemic treatment or radiation performed. Evaluation based on evidence acquired before treatment, supplemented or modified by the additional evidence acquired during and from surgery, particularly from pathologic examination of the resected specimen. p
5 Surgical resection performed with pre-surgical systemic treatment or radiation; tumor size/extension based on clinical evidence.
6 Surgical resection performed with pre-surgical systemic treatment or radiation, but tumor size/extension based on pathologic evidence.
8 Evidence from autopsy only (tumor was unsuspected or undiagnosed prior to autopsy).
9 Unknown if surgical resection done,
Not assessed; cannot be assessed
Unknown if assessed,
Not documented in patient record,
For sites with no TNM scheme: not applicable.
