NAACCR XML ID: lnSize

Notes

Note 1 Physician Statement

• Physician statement of Lymph Nodes Size can be used to code this data item when no other information is available.

Note 2 Criteria for coding LN size

• The metric is the size of the largest tumor deposit in the lymph node, not the size of the overall lymph node that is involved.

• For larger nodes however, the size of the deposit becomes essentially the size of the overall lymph node as the nodes become almost entirely overtaken with tumor.

• Code the size of the largest deposit if pathology reports separately list the size of a deposit and the size of the overall lymph node that the deposit is involving.

Note 3 Clinical vs Pathological size

• Code the clinical node size when the largest involved node is not examined pathologically.

• Code the pathological node size when the largest involved node (or same level) is examined clinically and pathologically, even if the pathological size is smaller.

• Code the size of the largest deposit when the pathology report separately lists the size of a deposit and the size of the overall lymph node that the deposit is involving.

• *Example* Clinical evaluation shows 1.5 cm (15 mm) Level II lymph node, pathological examination shows positive Level II node 1.3 cm (13 mm), with size of largest nodal deposit 1.3 mm

• Code 13.0.

Note 4 Regional vs. distant nodes

• Do not code the size of any distant nodes.
