Attempts have been made to develop effective therapeutic strategies to combat lung cancer, such as the identification of mutations in epidermal growth factor receptor (EGFR), K-Ras, and p53, and the EGFR-targeted therapy; however over 5 years prognosis is about 16% in NSCLC and ever lower for SCLC [3]. This evidence concerns the gene EGFR and small cell lung carcinoma.
