Question:
Scope of Regional Lymph Node Surgery/EOD Fields: When a patient has two simultaneously diagnosed primaries, and a regional lymph node dissection intended for one of the primaries removes nodes that are also regional for the other primary, is the information from the lymph node dissection coded for both primaries?
Discussion:
Answer:
For cases diagnosed 1998-2003:
If the lymph nodes are negative, the status of nodes that are regional for both sites would be used to code the EOD and Site-Specific Surgery fields for both sites.
If any of the lymph nodes are positive use the histology from the lymph nodes to determine how the EOD and Site-Specific Surgery will be coded. For example: If prostate cancer is an incidental finding when a cystoprostatectomy and pelvic lymph node dissection are done to treat a bladder cancer, and all of the positive lymph nodes reflect the histology of the prostate primary (adenocarcinoma), code the nodes as positive for the prostate primary and negative for the bladder primary.
