Hepatoduodenal lymph node (HDLN) positivity is considered distant metastasis in gastric cancer according to the seventh American Joint Committee on Cancer (AJCC) classification. In contrast, the International Union Against Cancer seventh edition and the Japanese Gastric Cancer Association both consider HDLN as a regional lymph node that can be included in the context of a curative resection. The purpose of this study was to determine whether there was justification for considering HDLN involvement as a distant metastasis for which resectional surgery could not have survival benefit. ⋯ It is inappropriate to include the HDLN in the distant metastatic lymph node group in gastric cancer. The seventh AJCC criteria for node grouping should be revised.
