Status Final References Source 1: 2007 SEER Manual pgs: C-644 Notes: Appendix C Source 2: pgs: Notes: Question MP/H Rules/Multiple primaries--Breast: When an in situ diagnosis is followed by an invasive diagnosis in the same breast 1.5 years later, is it a new primary? See discussion. Discussion Pt had a core bx 1/07 that showed DCIS. Pt refused resection, followed by chemo and/or XRT. A year and a half later (6/08) the pt returns for a MRM which shows infiltrating duct ca and positive LNS. The 6/08 information came in as a Correction Record. The comment in the Correction Record stated “Per MD, pt didn’t see any urgency and delayed surgery 1.5 year after diagnosis. The patient did not have any rx in that time period. Not specifically stated that pt had progression – only info is that pt had no adenopathy 1/07 and then 6/08 had positive LNS. Is the 6/08 a new primary? Answer Abstract the 6/08 invasive diagnosis as a separate primary according to rule M8. Rule M8 applies whether or not the later diagnosis in this case is progression of disease.
