WebMar 12, 2024 · The purpose of CTCS (Ministry of Railways 2009) is to define a train control system for Chinese Railways to realize interoperability of train control system in the … A circulating tumor cell (CTC) is a cell that has shed into the vasculature or lymphatics from a primary tumor and is carried around the body in the blood circulation. CTCs can extravasate and become seeds for the subsequent growth of additional tumors (metastases) in distant organs, a mechanism … See more CTCs that originate from carcinomas (cancers of epithelial origin, which are the most prevalent) can be classified according to the expression of epithelial markers, as well as their size and whether they are apoptotic. … See more To date, a variety of research methods have been developed to isolate and enumerate CTCs. The only U.S. Food and Drug Administration (FDA) cleared methodology for enumeration of CTC in whole blood is the CellSearch system. Extensive clinical … See more CTCs were observed for the first time in 1869 in the blood of a man with metastatic cancer by Thomas Ashworth, who postulated that "cells identical with those of the cancer itself … See more The detection of CTCs may have important prognostic and therapeutic implications but because their numbers can be very small, these cells are not easily detected.
