Successful crizotinib monotherapy in EGFR-mutant lung adenocarcinoma with acquired MET amplification after erlotinib therapy
MET is a driver oncogene in non-small-cell lung cancer (NSCLC), and its amplification is associated with acquired resistance to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors. A 56-year-old Japanese male with lung adenocarcinoma harboring an EGFR exon 21 L858R mutation received erlotinib to which he responded for 12 months. After disease progression, re-biopsy analyses revea...
متن کاملSignaling networks assembled by oncogenic EGFR and c-Met.
A major question regarding the sensitivity of solid tumors to targeted kinase inhibitors is why some tumors respond and others do not. The observation that many tumors express EGF receptor (EGFR), yet only a small subset with EGFR-activating mutations respond clinically to EGFR inhibitors (EGFRIs), suggests that responsive tumors uniquely depend on EGFR signaling for their survival. The nature ...
متن کاملPooled analysis of clinical outcome for EGFR TKI-treated patients with EGFR mutation-positive NSCLC
Patients with non-small-cell lung cancer (NSCLC) appear to gain particular benefit from treatment with epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKI) if their disease tests positive for EGFR activating mutations. Recently, several large, controlled, phase III studies have been published in NSCLC patients with EGFR mutation-positive tumours. Given the increased patient ...
متن کاملExpression of MET and SOX2 genes in non-small cell lung carcinoma with EGFR mutation.
Non-small cell lung carcinoma (NSCLC) is a leading cause of cancer-related deaths. Aberrance of the two oncogenes MET and SOX2 are frequently encountered in NSCLC. Exons 18 through 21 of the EGFR gene were screened and MET and SOX2 immunostaining was conducted to analyze the immunohistological staining of MET and SOX2 and the EGFR mutation status. One hundred and fifty tissue samples were exami...
متن کاملc-Met ectodomain shedding rate correlates with malignant potential.
PURPOSE Many proteins are proteolytically released from the cell surface by a process known as ectodomain shedding. Shedding occurs under normal physiologic conditions and can be increased in certain pathologies. Among the many receptors for which ectodomain shedding has been shown is c-Met, the hepatocyte growth factor (HGF) receptor tyrosine kinase. HGF stimulates mitogenesis, motogenesis, an...
