Different risks of nodal metastasis by tumor location in remnant gastric cancer after curative gastrectomy for gastric cancer

Background Curative surgery for remnant gastric cancer (RGC) after gastrectomy for gastric cancer (GC) can be challenging. We examined the risk factors for lymph node metastasis in RGC, especially for tumors located at the greater curvature (G) or non-greater curvature (NG), to determine the appropriate indications of curative surgery.
