Cell-free DNA (cfDNA): Clinical Significance and Utility in Cancer Shaped By Emerging Technologies.
Precision oncology is predicated upon the ability to detect specific actionable genomic alterations and to monitor their adaptive evolution during treatment to counter resistance. Because of spatial and temporal heterogeneity and comorbidities associated with obtaining tumor tissues, especially in the case of metastatic disease, traditional methods for tumor sampling are impractical for this ap...
متن کاملClinical perspective of cell-free DNA testing for fetal aneuploidies.
Cell-free DNA testing in maternal blood provides the most effective method of screening for trisomy 21, with a reported detection rate of 99% and a false positive rate of less than 0.1%. After many years of research, this method is now commercially available and is carried out in an increasing number of patients, and there is an expanding number of conditions that can be screened for. However, ...
متن کاملIntroducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA
Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...

متن کاملOverall evaluation of the clinical value of prenatal screening for fetal-free DNA in maternal blood
OBJECTIVE To explore the clinical value of prenatal screening for fetal-free DNA in maternal blood. METHODS A total of 10,275 maternal blood samples were collected from October 2012 to May 2016 at the prenatal diagnosis center of Changzhou Woman and Children Health Hospital. RESULTS Among 10,275 pregnant women accepted noninvasive prenatal testing (NIPT), 9 cases could not get the results a...
