Although many molecular genetic studies indicate that there are some genetic mutations in non-small cell lung cancer (NSCLC), including EGFR, KRAS, PIK3CA, BRAF, ALK, DDR2, and PDGFRA [16, 17], only a few studies have focused on the genetic events of salivary gland-type lung carcinomas. Here, KRAS is linked to non-small cell lung carcinoma.
