A comparison of immunohistochemical stain quality in conventional and rapid
microwave processed tissues.

Same-day turnaround of pathology specimens is desirable in this era of
managed care, and rapid microwave tissue processing produces histologic
features of a quality equivalent to overnight processing. We studied whether
microwave-assisted rapid tissue processing adversely affects the quality of
immunohistochemical staining. We selected 30 specimens (20 neoplastic and 10
nonneoplastic) from our routine surgical pathology workload. Paired large
tissue blocks were made from each specimen type, one for microwave-assisted
rapid processing and one for conventional processing. Two microarrays of 60
punches each were made from the donor blocks. The microarray blocks were
examined for intensity and extent of staining by 44 commonly used
antibodies. Slides were reviewed independently by 2 pathologists blinded to
the type of processing used. In 5,280 tissue punches examined, we found a
high degree of concordance in quality, as measured by intensity and extent
of immunohistochemical staining, between microwave and routinely processed
tissues. Our study demonstrates that quality of immunohistochemical staining
is similar between rapid microwave and conventional processing. The
potential need for immunohistochemical analysis is not a contraindication
for microwave-assisted rapid tissue processing.

Subject: [Histonet] IHC on Sakura Xpress processed tissue
Can I get feedback from the Histonet world on how IHC staining is effected
by switching from standard processing to processing on the Xpress? Does
anyone see any other drawbacks to the technology?
