Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/19/2009 [ Schema ]

Thyroid

CS Lymph Nodes

Note 1: Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in the field Mets at DX.
Note 2: This field includes all lymph nodes defined as Levels I-VI and Other by AJCC. The complete definitions are provided in the General Instructions for head and neck cancers.
Note 3: Assignment of N value for thyroid does not depend on laterality. All codes for nodal involvement include ipsilateral bilateral, contralateral, and midline lymph nodes.
