In lung cancer, targetable activating alterations in cancer genes, such as EGFR, ALK, RET, ROS1 and MET, are usually mutually exclusive. Rare lung cancer cases with coexistent alterations of EGFR and ALK or EGFR mutations with RET or ROS1 rearrangements have been reported. In this study, we report 15 patients (3 men and 12 women; 14 Caucasians and 1 African American) with ages ranging from 43 to 81 years (median 60 years) with lung adenocarcinoma in which coexistent alterations of two cancer-associated genes, including ALK, ROS1, or RET rearrangement or MET amplification were present...

For some years now, we have entered the genomic age of tumour genotyping from a medical point of view. Technological breakthroughs in both biology and information science now allow a genomic analysis of cancers in everyday medical practice with, in some case, a major impact on patient care not only for the choice of therapy (i.e. EGFR mutations in lung adenocarcinoma), but also for diagnosis and monitoring of the disease. Tumour genotyping is performed from formalin-fixed paraffin-embedded tissues used for diagnosis of cancer...

OBJECTIVE: Epidermal growth factor receptor (EGFR) gene mutation status is a well-established predictor of the efficacy of EGFR tyrosine-kinase inhibitor (TKI) therapy in patients with non-small cell lung cancer. Recently, differences in EGFR mutation subtypes have been reported to be associated with the efficacy of EGFR-TKI therapy. The prognostic impact of EGFR mutation status and subtypes remains controversial, however. METHODS: We retrospectively reviewed 939 patients with surgically resected adenocarcinomas who underwent EGFR mutation status analysis between January 2010 and December 2014...

Blood-based liquid biopsies, including tumor-educated blood platelets (TEPs), have emerged as promising biomarker sources for non-invasive detection of cancer. Here we demonstrate that particle-swarm optimization (PSO)-enhanced algorithms enable efficient selection of RNA biomarker panels from platelet RNA-sequencing libraries (n = 779). This resulted in accurate TEP-based detection of early- and late-stage non-small-cell lung cancer (n = 518 late-stage validation cohort, accuracy, 88%; AUC, 0.94; 95% CI, 0...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide, mainly because of its poor prognosis. A valid mechanism-based prognostic biomarker is urgently needed. γ-hydroxy-1,N(2) -propanodeoxyguanosine (γ-OHPdG) is an endogenously formed mutagenic DNA adduct derived from lipid peroxidation (LPO). We examined the relationship of γ-OHPdG with hepatocarcinogenesis in two animal models and its potential role as a prognostic biomarker for recurrence in HCC patients. Bioassays were conducted in the Xeroderma pigmentosum group A knockout mice (Xpa(-/-) ), and the diethylnitrosamine (DEN)-injected mice, both prone to HCC development...

Breast cancer susceptibility genes 1 and 2 (BRCA1 and BRCA2) mutations are associated with hereditary breast and ovarian cancer syndromes (HBOC). However, certain individuals with breast cancer do not meet high-risk factors for hereditary breast cancer screening based on age, family history, and biology of malignancy. We present a patient with relapsed breast cancer who developed progressive disease with significant tumor burden causing a recurrent pleural effusion. Next-generation sequencing (NGS) done on a tumor biopsy was positive for the BRCA2 mutation...

According to the latest data, lung cancer is one of the most common cancer worldwide, men contributing nearly 21.2% and women 8.6% of all diagnosed cancers. Late detection of tumour drastically reduces the chance for a cure. Thus, it is important to search for candidate biomarkers for screening of early stage nonsmall cell lung carcinoma (NSCLC). Tumour suppressor genes, DLEC1, TUSC4 and MLH1, localized on 3p21 are recognized to play a role in NSCLC carcinogenesis. The aim of this study was to assess the relationship between the DLEC1, TUSC4 and MLH1 mRNA expression, and clinical features of NSCLC patients, tobacco addiction, and tumour histopathological characteristics...

Lung cancer is the leading cause of cancer-related death worldwide. The poor prognosis is partly due to lack of efficient methods for early diagnosis. MicroRNAs play roles in almost all aspects of cancer biology, and can be secreted into the circulation and serve as molecular biomarkers for the early diagnosis of cancer. In the present study, we determined the expression of miR-96 and the function of its target genes in lung cancer through bioinformatic analysis. Four microRNA expression profiles of lung cancer were downloaded from Gene Expression Omnibus and the data were analyzed using SPSS 16...

The extracellular microenvironment is an integral component of normal and diseased tissues that is poorly understood owing to its complexity. To investigate the contribution of the microenvironment to lung fibrosis and adenocarcinoma progression, two pathologies characterized by excessive stromal expansion, we used mouse models to characterize the extracellular matrix (ECM) composition of normal lung, fibrotic lung, lung tumors, and metastases. Using quantitative proteomics, we identified and assayed the abundance of 113 ECM proteins, which revealed robust ECM protein signatures unique to fibrosis, primary tumors, or metastases...
