does lymph node dissection alter survival?
GROUND: Extragastric lymphadenectomy (D2 node dissection) is strongly supported by Japanese data to have survival benefit. Randomized trial data are either inconclusive or nonsupportive of this view. We have reviewed a prospectively gathered database of 18,346 cases of gastric carcinoma from a gastric cancer patient care evaluation study conducted by the American College of Surgeons to assess whether the performance of extragastric node dissection was associated with improved survival in patients who had resection with curative intent (all margins microscopically clear). STUDY DESIGN: We reviewed a subgroup of patients with curatively resected gastric carcinoma and compared the outcome in patients having extragastric lymph node dissection with the outcome in patients who did not have dissection of N2 nodes. RESULTS: Among the 3,804 patients having curative resection in the long-term study with more than a five-year follow-up, 695 had dissection of the nodes along the celiac axis, hepat
