Children's researchers unearth cells fueling treatment resistance & recurrence; findings support cancer stem cell hypothesis BOSTON, June 8, 2011 /PRNewswire-USNewswire/ -- Researchers at Children's Hospital Boston have found a marker called ABCB5 that both tags a small proportion of cells within colorectal cancers and fuels resistance in those cells to standard treatments.

SAN DIEGO, May 20 /PRNewswire-FirstCall/ -- An interim analysis of a study presented today at the 39th Annual Digestive Disease Week (DDW) Conference found that, among patients at increased risk for colorectal cancer who completed an annual fecal immunochemical (FIT) test, detection of cancerous lesions occurred an average of 26.5 months earlier than would have occurred during the three- or five-year study-required colonoscopy.
