Detection of Cell-Free DNA in Blood Plasma Samples of

This review surveys the use of cellular and cell-free DNA for the Abstract. Cell-free tumor DNA (ctDNA) is a kind of potential tumor biomarkers originated from cancer lesion in the circulating liquids. Liquid biopsy, as a minimally invasive or noninvasive manner, is a cutting-edge technology to detect ctDNA and other circulating biomarkers in the blood or other body fluids. ctDNA is mostly used for cancer patients to select targeted drugs in clinical 2015-10-16 · Next-generation sequencing of cell-free circulating solid tumor DNA addresses two challenges in contemporary cancer care.

Although cell-free DNA (cfDNA) has emerged as the favored nucleic acid to analyze in liquid biopsy samples, there are situations when this marker fails to provided necessary information. In such cases, cell-free RNA (cfRNA) might help fill the void. The first, looking at circulating-free DNA in non-small cell lung tumor samples, used a manual 12-plex PCR that covered the most common hotspot mutations. In 68 retrospective samples with matched tumor samples and circulating cell-free DNA samples they determined a sensitivity of their assay at 58% and an estimated specificity of 87%.
