Background: Epidermal growth factor receptor (EGFR) mutations, and to a lesser extent EGFR copy number variations, have been correlated with response to EGFR tyrosine kinase inhibitors (TKIs). In contrast, KRAS mutations have been recently associated with resistance to […]

Background: Mutations involving the epidermal growth factor receptor (EGFR) correlate with responsiveness to tyrosine kinase inhibitors (TKIs), which significantly improves patient survival in lung adenocarcinoma (AC). These mutations are described to be more frequent in non-mucinous lepidic adenocarcinomas (nmBAC). The unquestionable importance of determining the presence of these mutations, even in samples with […]

Background: Non-small cell lung cancer (NSCLC) is classified in two main categories: adenocarcinoma (AC), which includes bronchioloalveolar carcinoma (BAC), and squamous cell carcinoma (SCC). Activating mutations and increased copy number of the EGFR gene have been reported in tumors from patients with NSCLC with increased response rate to tyrosine kinase inhibitors (TKIs). There is […]

Background: Activating mutations of the EGFR gene were identified in tumors from patients with non small cell lung cancer (NSCLC) that responded to therapy with tyrosine kinase inhibitors (TKIs). More recently, survival has been reported to significantly increase amongst patients carrying a […]
