Endoscopic Resection for Undifferentiated Early Gastric Cancer: Focusing on Histologic Discrepancies Between Forceps Biopsy-Based and Endoscopic Resection Specimen-Based Diagnosis
2014
Background
Before endoscopic resection (ER), a considerable number of undifferentiated early gastric cancer (UD-EGC) cases were initially diagnosed as atypical glands, dysplasia, or differentiated EGC (D-EGC) based on forceps biopsy specimens. As UD-EGC carries a high risk of resection margin involvement, identifying the predictive factors for UD-EGC cases with histologic discrepancy (HD) is of clinical importance.
