Not affiliated When either EGFR or HER-2 is significantly increased in a cancer, it often indicates a more aggressive tumor and a poorer patient prognosis. EGFR mutations were detected at significantly lower MAFs in patients with brain metastases, suggesting that these patients risk for a false positive result. Certain mutations called "activating mutations" in the EGFR gene can result in excessive signaling for growth and uncontrolled proliferation of cancer cells. 2011;7(4):519-541 [On-line information]. Also, patients may wish to consult their health insurance company as to whether this blood testing would be covered. Kimura H, Fujiwara Y, Sone T, et al. Cytology samples including fine needle aspirate and pleural effusion can be used successfully to determine EGFR mutation status provided that sensitive testing methods are employed. The primary differences between EGFR and HER-2 testing are that they are ordered to help evaluate different types of cancer and that the drugs that have been developed to target them are specific for that particular receptor, EGFR or HER-2.
