Can Superextended Lymph Node Dissection be Justified for Gastric Cancer with Pathologically Positive Para-aortic Lymph Nodes?

Background The prognosis of patients with gastric cancer and para-aortic lymph node (PALN) metastasis is poor. Recent Japanese randomized trials concluded that prophylactic PALN dissection is not effective for curable advanced gastric cancer. However, the value of curative resection in patients with pathologically positive PALN is not determined yet.
