Can Differences in Bowel Function After Surgery for Rectal Cancer Be Identified by the European Organization for Research and Treatment of Cancer Quality of Life Instrument?

Abstract
Bowel function is an important outcome after rectal cancer surgery that affects quality of life (QOL). Postoperative bowel function is often assessed with QOL instruments, but their ability to detect functional differences has not been evaluated. This study evaluated the efficacy of the European Organization for the Research and Treatment of Cancer (EORTC) Core (C)-30 and Colorectal (CR)-38 QOL instruments in identifying functional differences among patients undergoing sphincter-preserving surgery, grouped by clinical and treatment-related factors known to be associated with bowel function.
