Clinical Sensitivity Verification Study of Circulating Tumor Cells Gene Mutation Detection From Advanced NSCLC Patients

Study Overview
=================
Brief Summary
-----------------
Verify the Coincidence rate between Circulating tumor cells (CTCs) and tumor tissue or Circulating tumor DNA (ctDNA) of advanced NSCLC patients with Driver gene mutation

Detailed Description
-----------------
Enrich CTCs from advanced Non-Small Cell Lung Cancer (NSCLC) patients with Driver gene mutation, and detect the Epidermal Growth Factor Receptor (EGFR) mutation, Anaplastic lymphoma kinase (ALK) fusion, ROS proto-oncogene receptor tyrosine kinase 1 (ROS1) fusion, RET proto-oncogene (RET) fusion and Mesenchymal-Epithelial Transition factor (MET) 14 exon skipping by Lung cancer Polymerase Chain Reaction (PCR) panel kit, and verify the mutation coincidence rate between CTCs and tumor tissue. Enrich ctDNA from advanced NSCLC patients with Driver gene mutation, detect the EGFR mutation by PCR, and detect the ALK fusion, ROS1 fusion, RET fusion and MET 14 exon skipping by next generation sequencing (NGS), and compare the mutation coincidence rate between CTCs and ctDNA.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Driver gene mutation-positive<br>Screen the enrolled patients according to the admission criteria. The detection of lung cancer Polymerase Chain Reaction (PCR) panel kit in the hospital requires the use of tissue samples and the results show a Driver gene mutation positive. | Other: nonintervention<br>* nonintervention<br>|
| Driver gene mutation-negative<br>Screen the enrolled patients according to the admission criteria. The detection of lung cancer Polymerase Chain Reaction (PCR) panel kit in the hospital requires the use of tissue samples and the results show a Driver gene mutation negative. | Other: nonintervention<br>* nonintervention<br>|
