[Histonet] HER2 on upper GI biopsies

We have had some oncologists asking for HER2 by IHC then reflexing for FISH if the IHC is negative or equivocal on upper GI tumors.
Our pathologists have been lookin for a recommended guideline to reflex for negatives in these types of cases, but haven't found any -- is anyone aware of FISH testing guidelines on GI cases?
Thanks in advance!
