Most prominently altered molecular marker genes in SCLC are associated with neuronal differentiation and/or growth such as the human achaete-scute homolog 1 (ASCL1) and the glycine receptor alpha1 subunit gene (GLRA1) [8,9], whereas NSCLC is characterized by deregulation of the Epidermal growth factor receptor (EGFR) and tumor-suppressor p53 [10,11]. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
