 Previous studies have revealed that EGFR mutation and/or EML4-ALK gene fusion rate was higher in the non-smoker Asian females with pulmonary adenocarcinoma.     ///    "104 consecutively resected lung adenocarcinomas from 396 non-smoker females (less than 100 cigarettes in a lifetime) at a single institution (Tongji University, Shanghai, China) were analyzed for mutations in EGFR, EML4-ALK, KRAS, HER2, BRAF, and PIK3CA. "    ///    "A majority of the mutations were mutually exclusive, except two with EGFR mutation and BRAF mutation, one with EML4-ALK fusions and PI3K mutation. "    ///    "10 (9.6 %) harbored EML4-ALK fusions, two harbored KRAS mutations, two harbored BRAF mutations, and two harbored PI3K mutations. "
