A new rapid method for detecting epidermal growth factor receptor mutations in non-small cell lung cancer.

ABSTRACT: Mutations in the epidermal growth factor receptor (EGFR) gene are associated with a favorable clinical response to the EGFR tyrosine kinase inhibitors gefitinib and erlotinib in non-small cell lung cancer (NSCLC). We present here, a new method for the rapid detection of the two most common EGFR mutations (delE746-A750 and L858R) from clinical samples. The methodology involves the combination of newly designed mutation-specific primers and a novel real-time PCR machine with an innovative thermo-control mechanism that enables ultrarapid PCR. We evaluated this method using a cell mixture composed of various ratios of lung cancer cells harboring mutated or wild-type EGFR, lung cancer tissues obtained by surgery, and a cytology sample obtained by bronchoscopy from a lung cancer patient.
