Partial Gastrectomy is Associated with Improved Overall Survival in Signet-ring Cell Gastric Cancer.
2021
ABSTRACT Background Signet-ring cell gastric cancer (SRGC) is a histological variant of gastric adenocarcinoma (GAC) with a worse prognosis compared to non-signet-ring cell gastric cancer (NSRGC). To our knowledge, the overall survival (OS) among patients with SRGC undergoing total/near-total (TG) versus partial gastrectomy (PG) has never been reported from a large-scale Western database. Methods We performed a retrospective analysis of patients with both SRGC and NSRGC using The National Cancer Database. Results In total, 17,086 patients were included. Patients who underwent TG versus PG were 25.5% (n = 770) versus 74.5% (n = 2246) for SRGC, and 20.9% (n = 2943) versus 79.1% (n = 11,127) for NSRGC, respectively. Patients who had SRGC were more likely to undergo TG (25.5% versus 20.9% P Conclusions Our results show that TG is not associated with improved OS in patients who undergo gastrectomy for GAC, even when adjusted for tumor location. The survival differences are more pronounced in the SRGC histology variant. The worst survival is observed in patients with SRGC who undergo TG after adjusting for different covariates.
