Spread of (a) Detection rates and (b) False Negative Rates among the studies of in vivo sentinel node mapping in colon cancer included in this review. In the figures, studies arising from either of the two centers with the most publications (ie The John Wayne Cancer Institute, California and the McLaren Reginal Cancer Centre, Michgan) on the topic are indicated separately to minimize any visual bias resulting from their inclusion. The remaining studies are divided into multicenter studies and all others.
