Metastatic cancer cells have the ability to break free from tissue, circulate in the blood stream, and form tumors all over the body, in a way acting like blood cells.

Circulating tumor cell (CTC) clusters — clumps of from 2 to 50 tumor cells that break off a primary tumor and are carried through the bloodstream — appear to be much more likely to cause metastasis than are single CTCs, according to a study from investigators at the Massachusetts General Hospital (MGH) Cancer Center.

Now a team of researchers in China has developed a new microfluidic chip that can quickly and efficiently segregate and capture live circulating tumor cells (CTCs) from a patient's blood, with potential applications for cancer screenings and treatment assessments.

«We wanted to utilize platelets» intrinsic tendencies to accumulate at wounds and to interact with circulating tumor cells, for targeted delivery of immune checkpoint inhibitors» said Gu, «Interestingly, we found the antibody can be promoted to release from activated platelets in the surgical site, due to generation of small platelet - derived microparticles upon the platelet activation.

«This development has the potential to enable earlier detection of solid tumors through a simple blood draw by substantially improving our ability to detect very low quantities of circulating DNA derived from tumor cells,» says corresponding author Hunter Underhill, M.D., Ph.D., who initiated the research while in the lab of senior author Jay Shendure, M.D., Ph.D., a professor in genome sciences at the University of Washington.

Epidermal growth factor receptor (EGFR) mutations found in the circulating free tumor DNA (ctDNA) from the plasma of advanced non-small cell lung cancer (NSCLC) patients correlates well with the EGFR mutations from patient - matched tumor tissue DNA.

Further research could test these cancer stem cell gene expression at the RNA and protein level in circulating tumor cells and biopsies from patients on trial.

The technique typically homes in on circulating - tumor DNA (ctDNA), genetic material that routinely finds its way from cancer cells into the bloodstream.

«Our circulating tumor cell device can release a tumor cell captured from a blood sample, enabling single cell analysis,» says Liu.

Adds Liu: «With metastatic cancers accounting for around 90 % of deaths from solid tumors, the hope is that one day a device that can enable the analysis of single tumor cells circulating in the blood could make a big difference in early diagnosis, detection and monitoring of numerous types of cancer, without invasive biopsies.»

In tumor - bearing mice, the researchers could monitor the real - time dynamics of circulating cancer cells released from a primary tumor.

Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize.

So my field is science and technology, so my work is circulating tumor cells where I isolate cancer cells from blood of patients and isolate their DNA and RNA and try to sequence them and try to device treatments for cancer treatment and therapy.

These cells are thought to break off from the original tumor and circulate in the blood, and may be a sign of an aggressive tumor.

Once settled in the microwell, the circulating tumor cells were burst open and the proteins released from inside each cell were separated according to differences in size or mass.

«Circulating tumor cells — cells from a tumor that have escaped into the bloodstream with the potential to spread into other tissues — are extremely useful for assessing a patient's disease in order to select the most appropriate treatment,» said UBC mechanical engineering professor Hongshen Ma, the lead researcher.

Circulating cell - free DNA (cfDNA) isolated from plasma or serum by noninvasive procedures can serve as a «liquid biopsy» and has potential as a biomarker for the tumor burden and survival prediction of breast cancer (BC).

We have invented new biomaterial surfaces based on natural halloysite nanotubes, that capture rare circulating tumor cells (CTCs) from blood while simultaneously repelling white blood cells.

Analysis of circulating cell - free DNA (cfDNA) reveals reversion mutation heterogeneity not discernable from a single solid - tumor biopsy and potentially allows monitoring for the emergence of PARPi resistance.
