Hi Sherri,

Welcome to GRACE. I'm sorry to hear that you have this diagnosis. Embryonic adenocarcinoma is an uncommon form of cancer which originates in germ cells, which are the cells that pass on genetic information through the production of the gametes used in reproduction,  More typically, cancers originate in somatic cells, which comprise all of the other cells that make up the body. I have not found any literature describing the use of EGFR inhibitors on such tumors, but I will make an inquiry to verify that.
