Serum peptide expression and treatment responses in patients with advanced non-small-cell lung cancer.

Epidermal growth factor receptor (EGFR) mutation is an important predictor for response to personalized treatments of patients with advanced non-small-cell lung cancer (NSCLC). However its usage is limited due to the difficult of obtaining tissue specimens. A novel prediction system using matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has been reported to be a perspective tool in European countries to identify patients who are likely to benefit from EGFR tyrosine kinase inhibitor (TKI) treatment.

Circulating microRNAs as novel biomarkers of ALK-positive nonsmall cell lung cancer and predictors of response to crizotinib therapy.

Circulating microRNAs are potential diagnostic and predictive biomarkers, but have not been investigated for patients with anaplastic lymphoma kinase (ALK)-positive lung cancer. In this exploratory study, we sought to identify potential plasma biomarkers for ALK-positive non-small cell lung cancer (NSCLC). A microRNA microarray was used to select ALK-related microRNAs in ALK-positive NSCLC (n = 3), ALK-negative NSCLC (n = 3), and healthy subjects (n = 3).

A comparison of ARMS and direct sequencing for EGFR mutation analysis and tyrosine kinase inhibitors treatment prediction in body fluid samples of non-small-cell lung cancer patients.

Background: Epidermal growth factor receptor (EGFR) mutation is strongly associated with the therapeutic effect of tyrosine kinase inhibitors (TKIs) in patients with non-small-cell lung cancer (NSCLC). Nevertheless, tumor tissue that needed for mutation analysis is frequently unavailable. Body fluid was considered to be a feasible substitute for the analysis, but arising problems in clinical practice such as relatively lower mutation rate and poor clinical correlation are not yet fully resolved.

[Erlotinib in the treatment of advanced non-small-cell lung cancer (NSCLC)].

Objective: Erlotinib is a small-molecule inhibitor of EGFR tyrosine kinase, showing a significant improvement of survival in non-small-cell lung cancer (NSCLC) after the failure of front-line chemotherapy. The aim of this study was to evaluate the antitumor efficacy and toxicity of Erlotinib in the treatment of advanced NSCLC patients.

Methods: A total of 104 patients with advanced NSCLC admitted in our department during December 2006 to November 2008 were enrolled in this study.

[Inhibitory effects of a combination of rmhTRAIL and gemcitabine on human non-small cell lung cancer cell line NCI-H460 cells in vitro and in vivo].

Objective: To evaluate the inhibitory effects of recombinant mutant tumor necrosis factor-related apoptosis-inducing ligand (rmhTRAIL) combined with chemotherapeutic agent gemcitabine (GEM) on human lung cancer cell line NCI-H460 cells in vitro and in vivo.

Methods: MTT was used to evaluate the cytotoxic effects of rmhTRAIL and GEM either used alone or in combination treatment on NCI-H460 cells. BAL B/c nude mice were transplanted with NCI-H460 tumor.
