I am currently doing FISH correlations on a number of cases done both here
and elsewhere in which the patient tissue was a 3+ on core biopsies but were
negative on subsequent big blocks using the DAKO HercepTest kit. I am also
monitoring the results closely on all HercepTest cases that I perform.
Preliminary results are leading me to believe that the temperature of both
the Kit reagents as well as the HercepTest wash buffer are a much bigger
factor than I had believed. There is a standing order here (Medical College
of Wisconsin & Froedtert Hospital) to no longer do this test on breast core
bx's until this problem is resolved. I'll let you know what I find out.

Is anyone using anything other than Herceptest for clinical Her-2/neu
stains. If so what antibody and detection and could you discuss scoring and
reporting the results?? Also has anyone done FISH correlations with IHC
results within your own laboratory?
