We aimed at revealing the clinical features of EML4-ALK fusion gene and EGFR mutation in non-small-cell lung cancer (NSCLC).     ///    The EGFR mutations and the EML4-ALK fusion genes are coexistent..     ///    Six patients who harbored both EML4-ALK fusion genes and EGFR mutations were identified in our study.     ///    EML4-ALK fusion gene defines a new molecular subset in patients with NSCLC.     ///    "In continuity correction ?? (2) test analysis, EML4-ALK fusion gene was correlated with sex, age, smoking status, and histology, but no significant association was observed between EML4-ALK fusion gene and clinical stage. "    ///    "EML4-ALK fusion gene was analyzed by real-time polymerase chain reaction, and EGFR mutations were analyzed by amplified refractory mutation system. "    ///    Detection of EML4-ALK fusion gene and features associated with EGFR mutations in Chinese patients with non-small-cell lung cancer..     ///     Echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) and epidermal growth factor receptor (EGFR) define specific molecular subsets of lung cancer with distinct clinical features.     ///    "Among the 694 patients, 60 (8.65%) patients had EML4-ALK fusions. "    ///    "Meanwhile, to our surprise, six (0.86%) patients had coexisting EML4-ALK fusions and EGFR mutations. "
