Core Tip
Core Tip: This is a retrospective study to evaluate the clinicopathological character-istics, surgical outcomes, and survival of remnant gastric cancer (RGC) after previous gastrectomy for benign disease. We compared the RGC patients with primary proximal gastric cancer (PGC) who underwent total gastrectomy. The findings indicated that RGC and PGC had similar clinicopathological characteristics, including Lauren type and pathological tumor-node-metastasis stage, but RGC patients were older and had a lower number of resected lymph nodes. Although RGC is generally associated with a worse prognosis, there was no significant difference in perioperative morbimortality and survival between the groups.
