Intraoperative frozen section analysis of margin status as a quality indicator in gastric cancer surgery.

Introduction: Positive pathologic margins following gastric cancer (GC) resection carries a poor prognosis. We evaluated intraoperative frozen section (IFS) analysis of resection margins (RMs) as a quality indicator in GC surgery.

Methods: Patients referred to a provincial cancer agency with surgically resected non-metastatic GC between 2004 and 2012 were included.
