2016 SEER Manual
Question:
Scope of Regional Lymph Node Surgery--Lung: How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary? Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC. See Discussion.
Discussion:
There is a discrepancy in regional lymph nodes for lung between SEER and AJCC. Supraclavicular lymph nodes/cervical lymph nodes are distant for SEER but regional for AJCC. For SEER states, when there is an FNA or biopsy of a supraclavicular lymph node performed and it is positive for a lung primary and no other lymph nodes are examined, do you code 95 in Regional Nodes Positive/Regional Nodes Examined and code "1" for Scope of Regional Lymph Node Surgery or do you not count the FNA/biopsy of the supraclavicular lymph node since it is distant?
Answer:
For cases diagnosed through 2017, use the Collaborative Staging (CS) system to determine regional versus distant lymph nodes. Supraclavicular lymph nodes are regional for lung in CS.
Please note that Summary Stage is not the same as EOD, CS, or AJCC staging. Registrars should not use Summary Stage definitions for anything other than directly assigning the Summary Stage field.
