Core Tip

Core Tip: This is a retrospective study to investigate the survival of gastric cancer patients with positive peritoneal wash cytology but no peritoneal metastasis post-radical gastrectomy and to identify factors associated with long-term prognosis. Our study included 48 such patients and demonstrated that more effective treatment should be established for patients who are diagnosed with pN3b disease and vascular invasion.
