Probing circulating tumor cells in microfluidics.
Circulating tumor cells (CTCs) are important targets for study as we strive to better understand, diagnose, and treat cancers. However, CTCs are found in blood at extremely low concentrations; this makes isolation, enrichment, and characterization of CTCs technically challenging. Recently, the development of CTC separation devices has grown rapidly in both academia and industry. Part of this de...
متن کاملSlanted spiral microfluidics for the ultra-fast, label-free isolation of circulating tumor cells.
The enumeration and characterization of circulating tumor cells (CTCs), found in the peripheral blood of cancer patients, provide a potentially accessible source for cancer diagnosis and prognosis. This work reports on a novel spiral microfluidic device with a trapezoidal cross-section for ultra-fast, label-free enrichment of CTCs from clinically relevant blood volumes. The technique utilizes t...
متن کاملCirculating Tumor Cells and Tumor Dormancy
Metastatic cancer can recur months or even years after apparently successful treatment of the primary tumor. While the exact mechanisms leading to cancer recurrence remain poorly understood, failure to completely eliminate dormant micrometastases and solitary metastatic cells is believed to be a major contributor. Thus, while not of initial clinical concern, metastatic dormancy is still a signi...
متن کاملMetastasis and Circulating Tumor Cells
Cancer is a prominent cause of death worldwide. In most cases, it is not the primary tumor which causes death, but the metastases. Metastatic tumors are spread over the entire human body and are more difficult to remove or treat than the primary tumor. In a patient with metastatic disease, circulating tumor cells (CTCs) can be found in venous blood. These circulating tumor cells are part of the...
متن کاملCirculating tumor cells.
A typical cancerous tumor contains millions or even billions of cells harboring genetic mutations driving them to grow, divide, and invade the local tissue in which they’re embedded. However, as the cells proliferate, they don’t all stay in the neighborhood. Some cells slough off the edges of a tumor and are swept away by the bloodstream or lymphatic system. These so-called circulating tumor ce...
