Collaborative Stage

Note 1: Code only regional nodes and nodes, NOS in this field. Distant nodes are coded in CS Mets at DX.
Note 2: Regional lymph nodes for any part of the esophagus fall in the range from periesophageal/cervical to the celiac region. Contralateral and bilateral cervical, supraclavicular, and mediastinal lymph nodes are included.
Note 3: Celiac nodes are coded in CS Lymph Nodes for lower thoracic (abdominal) esophagus; they are coded in CS Mets at DX for cervical and intrathoracic (upper and middle) esophagus. Cervical nodes, NOS are coded in CS Lymph Nodes for cervical esophagus; they are coded in CS Mets at DX for intrathoracic esophagus.
Note 4: Lymph node stations/groups are listed in parentheses when applicable. See Figure 10.3 in the AJCC Cancer Staging Manual 7th Edition or Handbook for illustrations.
Note 6: The number of positive regional nodes is required to calculate the correct N category for this schema. Use codes 560, 610 or 710 when the pathology report assigns an N1, N2 or N3 category but does not specify the number of nodes involved, or the record identifies an N1, N2 or N3 category but the specific information about number of nodes involved is not available. Use codes (100-255, 265-280 and 305-500) rather than codes 560, 610 or 710 when information about the number of positive nodes is available, or when nodes are clinically positive but not removed for examination.

^ For CS Lymph Nodes codes 100-255, 265-280, and 305-500 ONLY, the N category for AJCC 7 staging is assigned based on the number of positive lymph nodes. When CS Lymph Nodes Eval is 0, 1, 5, or 9, the N category is assigned from the Lymph Nodes Clinical Evaluation AJCC 7 Table, using Regional Nodes Positive and CS Site-Specific Factor 1; when CS Lymph Nodes Eval is 2, 3, 6, 8, or not coded, the N category is determined from the Lymph Nodes Pathologic Evaluation AJCC 7 Table using Regional Nodes Positive.
