Lymph Nodes Size Mets 99 AJCC 6 Table - For N

Notes

**Note**: When CS Lymph Nodes is coded 150, 250, 350-450, or 505 and CS Mets at DX is coded 99, the AJCC 6 N and M categories are determined by the size of involved nodes as coded in CS Site-Specific Factor 2, Size of Metastasis in Lymph Nodes as shown in this table. A CS Site-Specific Factor 2 code takes precedence over a CS Lymph Nodes code for "stated as N"; however, if CS Site-Specific Factor 2 is coded as unknown, the N category may be assigned based on "stated as N" recorded in CS Lymph Nodes.
