Surgical outcome in patients with gastric adenocarcinoma in the upper third of the stomach

The extent of lymphadenectomy should be tailored to tumor location. Lymphadenectomy might include the lateroaortic lymph nodes for advanced gastric cancer in the upper third of the stomach and the supradiaphragmatic and lower paraesophageal nodes for tumors extending to the esophagus. Randomized controlled trials are needed to verify these indices.
