East Versus West: Differences in Surgical Management in Asia Compared with Europe and North America

In recent decades, there has been considerable worldwide progress in the treatment of gastric cancer. Gastrectomy with a modified D2 lymphadenectomy (sparing the distal pancreas and spleen) has increasingly gained acceptance as a preferable standard surgical approach among surgeons in the East and the West. Despite growing consensus significant differences still exist in surgical techniques in clinical trials and clinical practices secondary to variations in epidemiology, clinicopathologic features, and surgical outcomes among geographic regions. In addition, Western physicians tend to prefer adjuvant chemotherapy and radiotherapy after surgery instead of using S-1 chemotherapy, as is the preference in the East.
