e- Ab Sensor-based Real-time Detection of Mutant EGFR in Clinical Specimens From Patients of Non-small Cell Lung Cancer

The purpose of this study is to develop a real-time diagnostic technique with e- Ab sensor for specific EGFR mutation detection in clinical specimens of NSCLC patients, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of EGFR, the investigators evaluate the performance of e- Ab sensor, including reproducibility, sensitivity, specificity, and cross-reaction (such as detection of EGFR mutations other than L858R and DelL746-A750). The potential factors which may interfere with the results would be investigated. With such technique, the investigators can obtain EGFR mutation information of NSCLC patients in cost-saving and time-saving way and can offer more individualized treatment for the investigators patients.
