Question:
EOD-Lymph Nodes: If chemotherapy or radiation is given prior to the excision of an involved lymph node, should the size of the metastasis within the lymph node be coded from the subsequent surgical pathology report? See discussion.
Discussion:
For several sites, the size of the metastasis in an involved lymph node is integrated into the EOD-Lymph Node field. Should the size of the metastasis mentioned on the pathology report be ignored if the patient received radiation or chemotherapy prior to having the lymph node removed?
Answer:
For cases diagnosed 1998-2003:
Record the size of a lymph node metastasis described in the pathology report for cases that had pre-surgical treatment. However, if both the pre-treatment and post-treatment size of the lymph node metastases are available, use the larger size when coding the EOD-Lymph Node field.
