Combination of chemotherapy and gefitinib as first-line treatment for patients with advanced lung adenocarcinoma and sensitive EGFR mutations: A randomized controlled trial.

To explore the optimal treatment strategy for patients who harbor sensitive EGFR mutations, a head-to-head study was performed to compare chemotherapy and gefitinib in combination or with either agent alone as first-line therapy, in terms of efficacy and safety. A total of 121 untreated patients with advanced lung adenocarcinoma who harbored sensitive EGFR mutations were randomly assigned to receive gefitinib combined with pemetrexed and carboplatin, pemetrexed plus carboplatin or gefitinib alone. The progression-free survival (PFS) of patients in the combination group (17.

Potential Antitumor Activity of SIM-89 in Non-Small Cell Lung Cancer Cells.

Purpose: c-Met and its ligand, hepatocyte growth factor (HGF), play a critical role in oncogenesis and metastatic progression. The aim of this study was to identify inhibited enzymogram and to test the antitumor activity of SIM-89 (a c-Met receptor tyrosine kinase inhibitor) in non-small cell lung cancer.

Materials And Methods: Z'-LYTE kinase assay was employed to screen the kinase enzymogram, and mechanism of action (MOA) analysis was used to identify the inhibited kinases.

Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors in Advanced Squamous Cell Lung Cancer.

Background: The efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in squamous cell carcinoma (SCC) of the lung remains controversial, and the role of EGFR testing in patients with SCC of the lung remains debatable.

Patients And Methods: We retrospectively identified patients with stage IIIB or IV SCC of the lung who had undergone EGFR testing at Shanghai Chest Hospital from January 2009 to December 2013.

Results: A total of 29 EGFR mutation-positive patients (22 patients had received TKI therapy and 7 had not) and 151 EGFR wild-type patients (27 patients had received TKI therapy and 124 had not) were available for an analysis of efficacy.
