¹Study of submucosal cancer. Percentages represent proportion of patients with metastasis in lymph nodes of given station. All articles but Yoshikawa include both mucosal cancer and submucosal cancer; Yoshikawa includes only submucosal cancer cases. aLGA: Nodes along left gastric artery; SpH: Nodes at the hilum of spleen; aPHA: Nodes along hepatic artery proper; PAN: Paraaortic nodes.
