Pathologic Review of Regional Lymph Nodes (SEER)
Regional Lymph Nodes Positive
Number of Positive Regional Lymph Nodes (SEER)
Records the exact number of regional nodes examined by the pathologist and found to contain metastases. Beginning with tumors diagnosed on or after January 1, 2004, this item is a component of the Collaborative Stage system. For tumors diagnosed from 1988 through 2003, this item was part of the 10-digit EOD , detailed site-specific codes for anatomic EOD.
This data item is necessary for pathologic staging, and it serves as a quality measure for pathology reports and the extent of the surgical evaluation and treatment of the patient.
