Effect of double-layer structure in intramucosal gastric signet-ring cell carcinoma on lymph node metastasis: a retrospective, single-center study
Among all types of gastric cancer (GC), signet-ring cell carcinoma (sig-GC) accounts for 4–17% of cases. The prognosis of early sig-GC is relatively good, with the 5-year survival rate at 99.7%. However, the c...
