liquid biopsies

Sequencing circulating tumor DNA (ctDNA) within liquid biopsies permits tumor identification and tracking. 

After controlling for high levels of bacterial contamination in their lab and reagents, researchers detect microbial genetic material in plasma samples from healthy people and cancer patients.

The liquid biopsy, which detects cell-free tumor DNA, spotted undiagnosed cancers in some women, but had a greater number of false positives and false negatives.

Machine-learning algorithms tuned to detecting cancer DNA in the blood could pave the way for personalized cancer care.

The test can pick up several types of cancer, including pancreatic and ovarian, years before symptoms appear.

Fragments of circulating DNA from tumors are around 20 to 30 base pairs shorter than those from healthy cells, researchers report.
