Inquiry Details

2004 SEER Manual, 136-138. 1.d; 3.c
Question:
CS Lymph Nodes--Prostate: How is this field coded when no scan, scope or surgical evaluation of regional lymph nodes is performed for a case with localized disease in the primary site? See Discussion.
Discussion:
Prior to initiation of collaborative stage, SEER prostate guidelines instructed us to code lymph node involvement as negative when clinical or pathologic extension was coded 10-34 and there was no lymph node information. Is this guideline still in effect, or do we follow the collaborative stage rules which require lymph node information or, in absence of node info, usual treatment for localized disease?
Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.For prostate and other "inaccessible sites" with localized disease, code the regional lymph nodes as clinically negative when not mentioned on imaging or exploratory surgery.
