Associations between Dietary Intake of Choline and Betaine and Lung Cancer Risk

Evidence from human and animal research indicates that choline metabolic pathways may be activated during a variety of diseases, including cancer. We report results of a case-control study of 2821 lung cancer cases and 2923 controls that assessed associations of choline and betaine dietary intakes with lung cancer. Our results suggest that choline and betaine intake, especially higher betaine intake, may be protective against lung cancer through mitigating the adverse effect of smoking.


Prognostic Significance of Combinations of RNA-Dependent Protein Kinase and EphA2 Biomarkers for NSCLC

RNA-dependent protein kinase (PKR) is an independent prognostic variable in patients with non-small-cell lung cancer (NSCLC). In the current study, we investigated the correlation between PKR and 25 other biomarkers for NSCLC, identified the markers that could further improve the prognostic significance of PKR and elucidated the mechanisms of interaction between these markers and PKR.

PKR/EphA2 is a significant predictor of prognosis for NSCLC. PKR/EphA2 may be a promising approach to improving screening efficiency and predicting prognosis in patients with NSCLC.


Efficacy of Aerosolized Celecoxib Encapsulated Nanostructured Lipid Carrier in Non-small Cell Lung Cancer in Combination with Docetaxel

We evaluated the in-vivo anticancer activity of aerosolized Celecoxib encapsulated Nanolipidcarriers (Cxb-NLC) as a single therapeutic agent and combined with intravenously administered Docetaxel (Doc) against non-small cell lung cancer. Combination therapy with Cxb-NLC and Doc showed significant reduction in tumor growth which was further confirmed by proteomic analysis.


Therapeutic effect of 188Re-MAG3-depreotide on non-small cell lung cancer in vivo an in vitro

This study shows that 188Re-MAG3-depreotide can inhibit the
proliferation and invasion of A549 cells and SPC-A1 cells. Treatment with 7.4MBq 188Re-MAG3-depreotide via tail vein can significantly
suppress the in vivo cancer growth and induce the apoptosis of cancer cells. These findings demonstrate that 188Re-MAG3-depreotide can
induce the apoptosis of NSCLC cells and directly kill the NSCLC cells, which provide evidence for the radiotherapy of NSCLC.


Anticancer activity of fish oils against human lung cancer is associated with changes in formation of PGE2 and PGE3 and Alteration of Akt Phosphorylation

The beneficial effects of omega-3 fatty acids are believed to be due in part to selective alteration of arachidonate metabolism that involves cyclooxygenase (COX) enzymes. Here we investigated the effect of eicosapentaenoic acid (EPA) on the proliferation of human non-small cell lung cancer A549 (COX-2 over-expressing) and H1299 (COX-2 null) cells as well as their xenograft models. Our results of our study suggest that the ability of EPA to generate PGE3 through the COX-2 enzyme might be critical for EPA-mediated tumor growth inhibition which is at least partly due to down-regulation of Akt phosphorylation by PGE3.


Reirradiation for Locoregionally Recurrent Lung Cancer: Outcomes in Small Cell and Non-Small Cell Lung Carcinoma

To our knowledge this is the largest report analyzing outcomes for reirradiation (reRT) for locoregionally recurrent lung cancer, and the first to assess thoracic reRT outcomes in patients with small cell lung cancer (SCLC).

ReRT to the thorax for locoregionally recurrent NSCLC can provide palliative benefit, and a small subset of patients may experience long-term survival. Select SCLC patients may experience meaningful survival prolongation after reRT, but reRT for patients with symptomatic recurrence and/or extrathoracic disease did not offer meaningful survival or durable symptom benefit.


Network-based approach identified cell cycle genes as predictor of overall survival in lung adenocarcinoma patients

The purpose of this study was to delineate gene expression patterns for survival prediction in lung adenocarcinoma. We found significant correlation with genes enriched in the biological process of the cell cycle. Three genes (UBE2C, TPX2, and MELK) were more strongly associated with poor 5-year survival.


CHFR protein expression predicts outcomes to taxane-based first line therapy in metastatic NSCLC

Currently, there is no clinically validated test for the prediction of response to tubulin-targeting agents in non-small cell lung cancer (NSCLC). Here, we investigated the significance of nuclear expression of the mitotic checkpoint gene checkpoint with forkhead and ringfinger domains (CHFR) as predictor of response and overall survival (OS) with taxane-based first-line chemotherapy in advanced stage NSCLC.

CHFR expression is a novel predictive marker of response and OS in NSCLC patients treated with taxane-containing chemotherapy.


Impact of Epidermal Growth Factor Receptor and KRAS Mutations on Clinical Outcome in Resected Non-Small Cell Lung Cancer Patients

Surgery yields best results for non-small cell lung cancer (NSCLC) patients. Epidermal growth factor receptor (EGFR) and its downstream factor Kirsten rat sarcoma viral oncogene homolog (KRAS) are variably mutated in NSCLC. Such mutations predict clinical response to tyrosine kinase inhibitors. This study evaluated incidence and correlation of EGFR and KRAS mutations with clinicopathologic parameters and outcome in resected stage I to III NSCLC.

EGFR and KRAS mutations are frequent in adenocarcinomas and are not prognostic factors for survival. EGFR mutations could be used to identify patients suitable for adjuvant treatment with targeted therapy resulting in potentially improved outcomes.
