AIM: The contribution of the inflammatory mediator interleukin-17 (IL-17) in nonsmall cell lung cancer (NSCLC) malignancy has been reported in the literature. MicroRNA-181a-5p (miR-181a-5p) acts as a tumor suppressor which can regulate target gene at the posttranscriptional level. Our study aimed to investigate the interaction between IL-17 and miR-181a-5p in NSCLC. METHODS: 35 patients with NSCLC and 24 COPD controls were selected and examined in our study. In vitro, H226 and H460 cell lines were exposed to different doses (20, 40, 60, and 80 ng/mL) of IL-17 to examine the effect of IL-17 on miR-181a-5p and vascular cell adhesion molecule 1 (VCAM-1) expression...

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). Plasma levels of 21 microRNAs were differentially expressed for ALK-positive and ALK-negative NSCLC, including 14 down-regulated and 7 up-regulated microRNAs...

BACKGROUND: MicroRNA-516b (miR-516b) has been recently reported to be downregulated in nonsmall cell lung cancer (NSCLC). However, its clinical significance and biological function in NSCLC remain to be clarified. MATERIALS AND METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-516b in 82 paired fresh primary tumor tissues and NSCLC cell lines. The association of miR-516b expression with clinicopathological factors and prognosis was statistically analyzed by SPSS 21...

Deregulation of the microRNAs (miRNAs), a cluster of important posttranscriptional regulators, has been frequently associated with lung cancer (LCa). However, the emerging mechanism for how miRNAs is linked causally in the development of LCa chemoresistance is poorly understood. Herein, we established for the time the up-regulation of miR-369-3p in cisplatin (DDP)-resistant nonsmall cell lung cancer (NSCLC) tissues and cells. Its deregulation was found to be correlated to the magnitude of malignancy in well-characterized LCa cells...

The therapeutic options of nonsmall cell lung cancer (NSCLC) therapy has been changed since the first discovery of activating epidermal growth factor receptor (EGFR) mutations and the development of specific EGFR tyrosine kinase inhibitors, which resulted in the evolution of "personalized medicine." There are a considerable number of genomic aberrations in NSCLC serving as potential predictive biomarkers and drug targets and still more. We summarized the molecular pathways, potential targets, and possible impact on disease outcome in NSCLC...

BACKGROUND: During lobectomy in patients with lung cancer, the operated lung is often -collapsed and hypoperfused. Ischemia/reperfusion injury may then occur when the lung is -re-expanded. We hypothesized that remote ischemic preconditioning (RIPC) would decrease oxidative lung damage and improve gas exchange in the postoperative period. METHODS: We conducted a single-center, randomized, double-blind trial in patients with nonsmall cell lung cancer undergoing elective lung lobectomy...

Recent studies have indicated that the C-reactive protein (CRP)/albumin (CRP/Alb) ratio is associated with clinical outcomes in patients with various carcinomas. However, no studies have explored the association between the ratio of CRP/Alb and clinical outcome of inoperable patients with nonsmall cell lung cancers (NSCLCs). We examined the prognostic impact of CRP/Alb ratio on 165 stage IV NSCLC receiving palliative chemotherapy. The optimal cutoff level of CRP/Alb ratio was set at 0.195. The median follow-up time was 9 months (range, 1-74 months)...

BACKGROUND: Surgery remains the gold standard for patients with resectable nonsmall cell lung cancer. Current guidance identifies patients with poor pulmonary reserve to fall within a high-risk cohort. The aim of this study was to determine the clinical and quality of life outcomes of anatomical lung resection in patients deemed high risk based on pulmonary function measurements. METHODS: A retrospective review of patients undergoing anatomical lung resection for nonsmall cell lung cancer between January 2013 and January 2015 was performed...

INTRODUCTION: Erlotinib and gefitinib are the most commonly used epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in the treatment of EGFR mutant nonsmall cell lung cancer (NSCLC). Both erlotinib and gefitinib have shown equal efficacy in terms of response rates and overall survival. Hence, their toxicity profile becomes the most important determining factor in choosing these agents when treating EGFR mutant NSCLC. In this study, we compared the toxicity profile of erlotinib and gefitinib among an Indian subset of lung cancer patients...

Solitary bone metastasis to fibula in patients of lung carcinoma is a rare entity, with only four cases reported in literature. We, hereby, present a case of a 50 year-old-male who was given three cycles of chemotherapy for lung carcinoma with no distant metastasis but presented 2 months later with a fusiform, painful swelling around the knee that was clinically suspected to be inflammatory in nature but proved to be fibular metastasis on cytology. There was no evidence of skeletal metastasis on initial bone scan...

We studied the rate of incidental detection of lung carcinomas and its effect on long-term survival in a nationwide cohort of patients operated for nonsmall cell lung cancer (NSCLC). All patients operated for NSCLC in Iceland during 1991-2010 were included. Demographic and clinicopathological features were compared in patients diagnosed incidentally using chest radiography or computed tomography (CT), and in those with symptomatic presentation. Multivariate analysis was used to evaluate prognostic factors. Out of 508 patients, 174 (34%) were diagnosed incidentally; in 26% of cases by chest radiography and in 8% by CT...

In nonsmall-cell lung carcinoma patients, L858R mutation of epidermal growth factor receptor (EGFR) is often found, and molecular target therapy using EGFR tyrosine kinase inhibitors is effective for the patients. However, the treatment frequently develops drug resistance by secondary mutation, of which approximately 50% is T790M mutation. Therefore, the ability to predict whether EGFR will undergo secondary mutation is extremely important. We synthesized a novel radiofluorinated 4-(anilino)pyrido[3,4-d]pyrimidine derivative ([(18)F]APP-1) and evaluated its potential as a positron emission tomography (PET) imaging probe to discriminate the difference in mutations of tumors...

IREB2 is a gene that produces iron regulatory protein 2 (IRP2), which is critical to intracellular iron homeostasis and which relates to the rate of cellular proliferation. IREB2 lies in a lung cancer susceptibility locus. The aims were to assess 1) the relationship between iron loading, cell proliferation and IRP2 expression in lung cancer; 2) the potential of iron related pathways as therapeutic targets; and 3) the relevance of IRP2 in operated lung cancer patients.Cells of two nonsmall cell cancer (NSCLC) lines and primary bronchial epithelial cells (PBECs) were cultured with and without iron; and proliferation, apoptosis and migration were assessed...

The identification of oncogenic driver alterations that underlie sensitivity to small inhibitors has led to growing interest in identifying additional targetable oncogenes in nonsmall cell lung cancer. Although the therapeutic impact of the discovery of these alterations has now been widely demonstrated, the epidemiological data associated with each of these biomarkers remain insufficiently studied. In this review, we discuss the techniques used to discover each of these candidate oncogenes, their prevalence in nonsmall cell lung cancer, and briefly outline the epidemiological features of the major oncogenes and ways in which their identification can determine therapeutic strategies...
