Small cell lung cancer (SCLC) is a subtype of lung cancer, as accounting for 10% to 15% in lung cancer. As the difficulty in early diagnosis, short treatment time window and lacking specific therapeutic regimens for SCLC, the five-year survival rate of the patient was only about 5% (2,3). Therefore, the key points to improving SCLC survival is deeply understand the tumorigenesis mechanism and exploration of more effective and improved treatment methods %U http://tcr.amegroups.com/article/view/38161/html
