BACKGROUND: For many years, lung cancer has been the most common and deadly cancer worldwide. Early diagnosis of non-small cell lung cancer (NSCLC) in particular is very difficult because the symptoms are often ignored. The five-year survival rate is very low despite great improvements to therapy. Thus, there is an urgent need to identify prognostic biomarkers and target molecules for the clinical diagnosis and individualized treatment of NSCLC. METHODS: We performed quantitative real-time PCR to determine the expression levels of the long non-coding RNA (lncRNA) linc01433 in NSCLC and normal matched lung tissue...

Lung cancer is one of the most common cancers and the predominant cause of cancer-related death in the world. The low accuracy of early detection techniques and high risk of relapse greatly contribute to poor prognosis. An accurate clinical tool that can assist in diagnosis and surveillance is urgently needed. Circulating tumor DNA (ctDNA) is free DNA shed from tumor cells and isolated from peripheral blood. The genomic profiles of ctDNA have been shown to closely match those of the corresponding tumors. With the development of approaches with high sensitivity and specificity, ctDNA plays a vital role in the management of lung cancer as a result of its reproducible, non-invasive, and easy-to-obtain characteristics...

ROS1 rearrangement is a validated therapeutic driver gene in non-small cell lung cancer (NSCLC) and represents a small subset (1-2%) of NSCLC. A total of 17 different fusion partner genes of ROS1 in NSCLC have been reported. The multi-targeted MET/ALK/ROS1 tyrosine kinase inhibitor (TKI) crizotinib has demonstrated remarkable efficacy in ROS1-rearranged NSCLC. Consequently, ROS1 detection assays include fluorescence in situ hybridization, immunohistochemistry, and real-time PCR. Next-generation sequencing (NGS) assay covers a range of fusion genes and approaches to discover novel receptor-kinase rearrangements in lung cancer...

BACKGROUND: The EML4-ALK fusion gene has recently been identified as a driver mutation in a subset of non-small cell lung cancers. In subsequent studies, EML4-ALK has been detected in a low percentage of patients, and was associated with a lack of EGFR or KRAS mutations, younger age, and adenocarcinoma with acinar histology. Cases with the EML4-ALK fusion gene were examined to clarify the clinicopathological characteristics of young adenocarcinoma patients. METHODS: Between December 1998 and May 2009, 85 patients aged ≤ 50 with lung adenocarcinoma were treated at our hospital...

BACKGROUND: Lung cancer (LC) is the most common malignancy in the world. Many long non-coding RNAs (lncRNAs) have been reported to be associated with LC; however, the function of KCNQ1OT1 in LC requires exploration. METHODS: We conducted in silico analysis with data from The Cancer Genome Atlas to investigate the association between KCNQ1OT1 and LC. A Kaplan-Meier plotter was used to analyze the function of KCNQ1OT1 on LC patient prognosis. Quantitative reverse transcription-PCR (qRT-PCR) was performed to confirm previous results...

The ALK gene encodes a transmembrane tyrosine kinase receptor. ALK is physiologically expressed in the nervous system during embryogenesis, but its expression decreases postnatally. ALK first emerged in the field of oncology in 1994 when it was identified to fuse to NPM1 in anaplastic large-cell lymphoma. Since then, ALK has been associated with other types of cancers, including non-small-cell lung cancer (NSCLC). More than 19 different ALK fusion partners have been discovered in NSCLC, including EML4, KIF5B, KLC1, and TPR...

We describe a novel method using electromagnetic navigation bronchoscopy (ENB) without dye marking to perform vectorial localization for an impalpable peripheral lesion in the right lower lobe during diagnostic surgical resection in a 52-year-old woman. After the ENB registration process, the anesthetist changed the single-lumen endotracheal tube to a double-lumen endobronchial tube. Guided by the ENB system, the operator delivered the probe of the locatable guide to the planned site through the right lumen of the endobronchial tube...

BACKGROUND: Activating EGFR mutations, HER2, and HER3 are implicated in lung cancer; however, with the exception of EGFR gene amplification in lung adenocarcinoma harboring EGFR mutations, their involvement in disease progression during the early stages is poorly understood. In this paper, we focused on which receptor is correlated with lung adenocarcinoma progression in the presence or absence of EGFR mutation from stage 0 to IA1. METHODS: HER2 and HER3 expression and activating EGFR mutations in surgically resected lung adenocarcinoma exhibiting ground glass nodules on chest computed tomography and re-classified to stage 0 and IA1 were examined by immunohistochemistry and peptide nucleic acid-locked nucleic acid PCR clamp method, respectively...
