Over the past decade,the treatment of lung cancer gradually develops to individulized molecule targeted therapy for certain driver gene from chemotherapy based on histological features.High-throughput sequencing (HTS) technology has many advantages,such as higher throughput,shorter running time,less cost and so on.Further mining analysis to the massive data generated by HTS can reveal the mechanism of the development of lung cancer at genome level and seek new driver gene as the target of targeted therapy,it also can identify the gene alternatives that confer resistance to certain targeted therapy.
