[Histonet] new er pr cap guidelines

[Mike Pence]

My problem is that we do not work weekends. If I have a breast that comes in on Friday afternoon, I have to cut it in and have it embedded on Sat. morning. If the guidelines are 72 hr for everything then I can process it on Mondays.

I am not sure what the problem is here.  You have to fix for up to 72 hours no more you can do less time.  If you are already fixing your her2 for 48 hours, then what needs to change?   You are not going to submit different cassettes for Er/Pr to fix for longer?  You will submit them all and fix them all for 48 hours max.  The guideline is to prevent under AND over fixation.   Not to submit two different samples to fix for different times.

This was my first post about this issue: (I got no responses for)

Yes, the paper is there, however, I see they addressed the fixation time in NBF for er/pr but I do not see where they talk about the time changing for her2. So does this mean that I have to fix some of the tumor for her2 for only 48 hours, while the er/pr can be fixed 72 hours?

I am not sure why CAP would not address this up front. This is a big problem in our lab.

Dr. Hammond presented the new guidelines for ER (it is just ER not PR as I
recall) at the AIMM meeting in Florida at the end of January this year and the fixation times for Breast have been extended to 72 hours, it is supposed to be changed to 72 hours for Her2 as well but I do not know if that has happened yet or not.

Use this link to go to the CAP website to download the 2010 ER/PgR guidelines article (Arch Pathol Lab Med. 2010;134:E1-E16)from the CAP download page:

Anita:
Maybe your pathologist mean this recommendations:
"Consensus Recommendations on Estrogen Receptor
Testing in Breast Cancer By Immunohistochemistry"
(Appl Immunohistochem Mol Morphol 2008;16:513-520)?
These recommendations came not from CAP.
It is refer only to ER, but not PR.
