#2: 2007 SEER Manual, C-740. Appendix C
Question:
CS Site Specific Factor--Prostate: Please clarify how SEER registries should use code 040 for Site-Specific Factor 3 on prostate cases. See Discussion.
Discussion:
The 6/11/09 NAACCR Webinar on prostate cancer pointed out that SSF 3 code 040 refers the registrar to Note 4, which states "when the apical, distal urethral, bladder base, or bladder neck margins are involved and there is no extracapsular extension, use code 040." The webinar went on to say that code 040 ONLY applies to these specific margins, and that if other margins are involved (for example, the 'right lateral margin'), we should not use code 040. Is this consistent with SEER's interpretation of Note 4? Are we to ignore involvement of margins other than those specified in Note 4, and consequently code SSF 3 within the 000-032 range? Would this also apply to code 048 (extracapsular extension and margins involved)?
Answer:
Yes, SEER agrees. Code SSF3, code 040 per page C-740 of 2007 SEER manual exactly as stated in Note 4. According to the Inquiry and Response System of the CoC, Note 4 lists specific margins that were once thought to have a prognostic impact. Code 040 in SSF3 should be used only when those margins are involved.
Note 4 pertains to code 040, not to code 048.
