Capture-based next-generation sequencing (NGS) is a potentially useful diagnostic method to measure tumor tissue DNA in blood as it can identify concordant mutations between cell-free DNA (cfDNA) and primary tumor DNA in lung cancer patients. In this study, the sensitivity, specificity and accuracy of capture-based NGS for detecting ALK fusion in plasma cfDNA was assessed. 24 patients with tissue ALK-positivity and 15 who did not harbor ALK fusion were enrolled. 13 ALK-positive samples were identified by capture-based NGS among the 24 samples with tissue ALK-positivity...

The rapid adoption of next-generation sequencing (NGS) in clinical molecular laboratories has redefined the practice of cytopathology. Instead of simply being used as a diagnostic tool, cytopathology has evolved into a practice providing important genomic information that guides clinical management. The recent emphasis on maximizing limited-volume cytology samples for ancillary molecular studies, including NGS, requires cytopathologists not only to be more involved in specimen collection and processing techniques but also to be aware of downstream testing and informatics issues...

The advent of massively parallel sequencing has caused a paradigm shift in the ways cancer is treated, as personalised therapy becomes a reality. More and more laboratories are looking to introduce next generation sequencing (NGS) as a tool for mutational analysis, as this technology has many advantages compared to conventional platforms like Sanger sequencing. In Australia all massively parallel sequencing platforms are still considered in-house in vitro diagnostic tools by the National Association of Testing Authorities (NATA) and a comprehensive analytical validation of all assays, and not just mere verification, is a strict requirement before accreditation can be granted for clinical testing on these platforms...

Despite great histological and molecular heterogeneity, the clinical management of high-grade ovarian carcinomas remains unspecialized. As a major subgroup, high-grade serous ovarian carcinomas (HGSOCs) require novel therapies. In addition to utilizing conventional histological prognostic markers and performing oncogenetic investigations, the molecular diagnostic method of next generation sequencing (NGS) was performed to identify 'druggable' targets that could provide access to innovative therapy. The present study was performed in 45 HGSOC patients (mean age, 59...

Next-generation sequencing (NGS) has reached the molecular diagnostic laboratories. Although the NGS technology aims to improve the effectiveness of therapies by selecting the most promising therapy, concerns are that NGS testing is expensive and that the 'benefits' are not yet in relation to these costs. In this study, we give an estimation of the costs and an institutional and national budget impact of various types of NGS tests in non-small-cell lung cancer (NSCLC) and melanoma patients within The Netherlands...

Colorectal cancer (CRC) is the third most common cancer diagnosed in men and women and approximately 5% of cases are associated with identifiable germline mutations associated with hereditary cancer syndromes. Lifetime risks for CRC can approach 50%-80% for mutation carriers in the absence of endoscopic and/or surgical intervention, and early identification of at-risk individuals can guide clinical interventions for cancer prevention and treatment. Personal and family history and molecular phenotype of CRC tumors are used in determining which patients should be referred for clinical genetic evaluation...

Next-generation sequencing is making it possible to study the antibody repertoire of an organism in unprecedented detail, and, by so doing, to characterize its behavior in the response to infection and in pathological conditions such as autoimmunity and cancer. The polymorphic nature of the repertoire poses unique challenges that rule out the use of many commonly used NGS methods and require tradeoffs to be made when considering experimental design.We outline the main contexts in which antibody repertoire analysis has been used, and summarize the key tools that are available...

Development of targeted cancer therapy is accompanied by a search for markers allowing prediction of response to the particular treatment. Recently, the interest is focused, among other neoplasms, also on the therapy of ovarian cancer using new inhibitors of poly (ADP-ribose) polymerase (PARP) proteins, nuclear enzymes involved in the repair of single-stranded DNA breaks. The greatest benefit from the administration of PARP inhibitors have patients with a deleterious or potentially deleterious germ-line or somatic mutation of BRCA1 or BRCA2, two genes responsible for repair of double stranded DNA breaks...

INTRODUCTION: Targeted therapy significantly prolongs survival in lung adenocarcinoma. Current diagnostic guidelines include only EGFR and ALK testing. Next-generation sequencing (NGS) reveals more actionable genomic alterations (GAs) than stan dard diagnostic methods. Data on the influence of hybrid capture-based (HC-based) NGS on treatment are limited, and we investigated its impact on treatment decisions/clinical outcomes. METHODS: This retrospective study included patients with advanced lung cancer on whom HC-based NGS was performed between 11/2011-10/2015...

Cyclo(Arg-Gly-Asp) peptide (cRGD) decorated disulfide (SS) containing poly(vinyl alcohol) nanogels (cRGD-SS-NGs) with an average diameter of 142 nm prepared by inverse nanoprecipitation, "click" reaction, and cRGD conjugation are developed for targeted treatment of integrin overexpressing human glioblastoma in vivo. Doxorubicin (DOX) release from cRGD-SS-NGs is highly inhibited under physiological conditions, while accelerated at endosomal pH and in response to cytoplasmic concentration of glutathione. Confocal microscopy shows that cRGD-SS-NGs facilitate the cellular uptake and intracellular DOX release in αv β3 integrin overexpressing human glioblastoma U87-MG cells...
