We screened for EML4-ALK fusion genes and examined the clinicopathological and genetic characteristics of fusion-harboring NSCLC tumors.    ///    Clinicopathologic features of non-small-cell lung cancer with EML4-ALK fusion gene..     ///    Five EML4-ALK fusion genes were detected (four from 111 female samples and one from 202 male samples.     ///    "EML4-ALK fusion genes were observed predominantly in adenocarcinomas, in female or nonsmoking populations. "    ///    "Additionally, the EML4-ALK fusions were mutually exclusive with mutations in the EGFR, KRAS, and ERBB2 genes.. "
