The scope of regional lymph node surgery is collected for each surgical event even if surgery of the primary site was not performed.
Record surgical procedures which aspirate, biopsy, or remove regional lymph nodes in an effort to diagnose or stage disease in this data item. Record the date of this surgical procedure in data item Date of First Course of Treatment (NAACCR Item #1270) and/or Date of First Surgical Procedure (NAACCR Item #1200) as appropriate.
For primaries of the meninges, brain, spinal cord, cranial nerves, and other parts of the central nervous system (C70.0-C70.9, C71.0-C71.9, C72.0-C72.9), code 9.
For lymphomas with a lymph node primary site (C77.0-C77.9), code 9.
For an unknown or ill-defined primary (C76.0-C76.8, C80.9) or for hematopoietic, reticuloendothelial, immunoproliferative, or myeloproliferative disease regardless of site, code 9.
Do not code distant lymph nodes removed during surgery to the primary site for this data item. Distant nodes are coded in the data field Surgical Procedure/Other Site (NAACCR Item #1294).
Refer to the applicable AJCC Cancer Staging Manual for site-specific identification of regional lymph nodes.
If the procedure coded in this item was provided to prolong a patient’s life by controlling symptoms, to alleviate pain, or to make the patient more comfortable, then also record this surgery in the item Palliative Care (NAACCR Item #3270).
