egfr mutation testing methods

Impact of Epidermal Growth Factor Receptor Expression on Survival and Pattern of Relapse in Patients with Advanced Head and Neck Carcinoma. However, in situations where insufficient tumor cells are available for molecular testing from a tissue biopsy, or in situations where a tissue biopsy is not able to be taken, a blood test (liquid biopsy) may be an acceptable alternative testing method. Epidermal growth factor receptor (EGFR) mutations are generally detected in DNA from samples of tumor tissue obtained during biopsy or surgcial resection, usually in the form of formalin … Available Online at http://cancerres.aacrjournals.org/cgi/content/full/62/24/7350.

Mutation testing methods. 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. Pathologists and cancer specialists (oncologists) help interpret the precise significance of the exact EGFR mutation identified for each patient. “EGFR Liquid”, *8 developed by DNA Chip Research, is a minimally invasive testing method that uses blood, and it makes it possible to perform highly sensitive genetic testing by the … Clinical pharmacogenomic testing of KRAS, BRAF and EGFR mutations by high resolution melting analysis and ultra-deep pyrosequencing.
