Clinicopathological Features and Prognostic Impact of Microscopic Resection Margin Positivity After Curative Gastrectomy for Gastric Cancer

Microscopic resection margin positivity after gastrectomy for GC was linked to specific tumor characteristics, while positive peritoneal lavage cytology independently predicted poorer survival. To minimize the occurrence of resection margin-positive GC after gastrectomy, it is essential to identify risk factors during perioperative evaluation. Furthermore, treatment strategies based on lavage cytology status could improve prognosis in high-risk patients.
