[Histonet] Optimal processing for prostate needle biopsies

[Phyllis Thaxton]

How long are you pre-processing the prostate biopsies before processing on the 
XPress120? We use the XPress50 we fix the biopsies in Hollandes for 2 hours, 
then wash for 20 minutes, pre-processing solution for 10 minutes then process. 
We use Harris Hematoxylin in our H&E and morphology is good.

Subject: [Histonet] Optimal processing for prostate needle biopsies

I have a few questions regrading processing of prostate needle biopsies.
1.  What is optimal fixation time that the needle cores should be fixed for 
before loading these on the processors.
2.  Our cores are processed on Tissue tek Xpress x120 but the morphology is not 
so good. I'd like to know if any other labs have tried this processor for 
prostate needle cores processing and would like to know their experience as far 
as morphologic quality on slides
3.  What is the best H&E stain to use for prostate needle biopsies. We are 
currently using Mayer's which is giving us better staining than Harris. Any 
recommendations on which H&E is best suited for prostate needle biopsies.

Thanks
