Cellular change thought to happen only in late-stage cancers to help tumors spread also occurs in early-stage lung cancer as a way to bypass growth controls, say researchers at Mayo Clinic in Florida. The finding, reported in the July 11 issue of Science Translational Medicine, represents a new understanding of the extent of transformation that lung cancer -- and likely many other tumor types -- undergo early in disease development, the scientists say. They add that the discovery also points to a potential strategy to halt this process, known as epithelial-mesenchymal transition, or EMT. "Our study points to EMT as a key step in lung cancer progression during the earliest stages of cancer development," says lead investigator and cancer biologist Derek Radisky, Ph.D.
