Applications of molecular barcode sequencing for the detection of low-frequency variants in circulating tumour DNA from hepatocellular carcinoma.

Purpose: Liquid biopsy has emerged as a promising tool for minimally invasive and accurate detection of various malignancies. We aimed to apply molecular barcode sequencing to circulating tumour DNA (ctDNA) from liquid biopsies of hepatocellular carcinoma (HCC).

Study Design: Patients with HCC or benign liver disease were enrolled between 2017 and 2018.

Detection of recurrent, rare, and novel gene fusions in patients with acute leukemia using next-generation sequencing approaches.

Identification of gene fusion is an essential part in the management of patients with acute leukemia, not only for diagnosis but also in predicting the treatment outcome and selecting appropriate treatment. Adopting next-generation sequencing (NGS) technology for identification of gene fusion in patients with acute leukemia can be a good alternative to conventional tests. In the present study, the NGS RNA fusion gene panel test was applied to diagnostic samples of patients with acute leukemia to identify fusion genes more efficiently.

Clinical utility of targeted NGS panel with comprehensive bioinformatics analysis for patients with acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is a genetically complex and heterogeneous disease for which a wide range of genetic variations has been identified. With the need for comprehensive high-throughput analysis, we have designed a comprehensive next-generation sequencing (NGS) assay to detect somatic mutations, translocations, and copy number changes and have evaluated its clinical utility in patients with ALL. The panel reliably detected single nucleotide variations (SNV) and copy number variations (CNV) analysis was exceptionally useful in identifying genic and chromosomal CNV which dominated the genetic abnormalities of ALL.
