Published: May 2019

DNA-triggered reversible isolation and recovery of circulating tumor cells (CTCs) is presented based on a multivalent dual-specific aptamer-tethered rolling circle amplification (MA-RCA) network. The multivalent binding sites endow the MA-RCA network with a strong binding ability towards CTCs, and the repeated cell capture/release processes are also actualized in a noninvasive manner.

Purpose: Epstein-Barr virus (EBV)-positive Burkitt lymphoma (BL) affects children in sub-Saharan Africa, but diagnosis via tissue biopsy is challenging. We explored a liquid biopsy approach using targeted next-generation sequencing to detect the -immunoglobulin (-Ig) translocation and EBV DNA, assessing its potential for minimally invasive BL diagnosis.

Materials And Methods: The panel included targets for the characteristic -Ig translocation, mutations in intron 1 of , mutations in exon 2 of , and three EBV genes: EBV-encoded RNA (EBER)1, EBER2, and EBV nuclear antigen 2.

Background: While most thyroid nodules are benign, 7-15% are malignant. Patients with indeterminate thyroid nodules (specifically Bethesda IV/Thy3f) often undergo diagnostic hemithyroidectomy to reach a diagnosis on final histology. The aim of this study was to assess the feasibility of circulating large extracellular vesicles as diagnostic biomarkers in patients presenting with Thy3f thyroid nodules.

Cerebrospinal fluid (CSF) has emerged as a valuable liquid biopsy source for glioma biomarker discovery and validation. CSF produced within the ventricles circulates through the subarachnoid space, where the composition of glioma-derived analytes is influenced by the proximity and anatomical location of sampling relative to tumor, in addition to underlying tumor biology. The substantial gradients observed between lumbar and intracranial CSF compartments for tumor-derived analytes underscore the importance of sampling site selection.

Purpose: The detection of circulating tumor DNA (ctDNA) after curative-intent therapy in early breast cancer (EBC) is highly prognostic of disease recurrence. Current ctDNA assays, mainly targeting single nucleotide variants (SNVs), vary in sensitivity and specificity. While increasing the number of SNVs in tumor-informed assays improves sensitivity, structural variants (SVs) may achieve similar or better sensitivity without compromising specificity.
