Early diagnosis is difficult since suggestive clinical signs are usually associated with advanced tumors. Routine endoscopic screening should be performed for GSC patients with high risk factors. The treatment of choice for GSC should be the total removal of the gastric remnant including D2 lymphadenectomy. The pattern of lymph node metastases in GSC may differ from primary gastric cancer. Therefore, GSC may require a modified lymphadenectomy to include all important lymph node stations. After radical remnant gastrectomy, GSC has a prognosis similar to primary gastric cancer.
