Re: delay in fixation of tumor may alter histology, immunohistochemistry results eg E
I am actually going to have my tumor retested for ER status with Genoptix Laboratories. They do AQUA testing for ER status which is supposed to be more accurate. This test was originated by Yale University. Since my cancer has been so resistant to the anti HER2 drugs, I wonder if my ER status was incorrect. This study seems to support that mistakes may be more common than we think.
