SEER EOD-88, 3rd Ed, 9. January 1998
Question:
Discussion:
Patient underwent resection for adenocarcinoma of the rectum. Path final diagnosis stated: "Regional lymph nodes: met carcinoma in 18 of
43 lymph nodes. Pathologic stage (AJCC/UICC 6th edition): pT3, V2, pN2, pMx. See comment." Path comment: "There are additional macroscopic stellate deposits of carcinoma in the pericolic soft tissue. According to the 6th edition of the AJCC staging manual, these should be designated as "V2," indicating that there is a high likelihood that these represent foci of venous invasion."
Answer:
For cases diagnosed 1998-2003: Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
When the number of deposits is not mentioned, code Number of Regional Nodes Positive as 97 [Positive nodes but number of positive nodes not specified]. Unless the procedure is documented as a dissection, code Number of Regional Nodes Examined as 98 [Regional lymph nodes surgically removed but number of lymph nodes unknown/not stated and not documented as samping or dissection; nodes examined, but number unknown].
