Staging and surgical approaches in gastric cancer: A systematic review

All patients should be discussed at a multidisciplinary team meeting and a staging CT of the chest and abdomen should always be performed. Diagnostic laparoscopy should be performed in patients at risk for stage IV disease. A D2 LND is preferred for curative-intent resection in advanced non-metastatic gastric cancer. At least 16 LNs should be assessed for adequate staging of curative-resected gastric cancer. Gastric cancer surgery should aim to achieve an RO resection margin. In the metastatic setting, surgery should only be considered for palliation of symptoms. Patients should be referred to higher volume centres, and those with adequate support to manage potential complications. Laparoscopic resections should be performed to the same standards as open resections.
