Extended lymph node dissection (D2 resection) should now be performed routinely in the curative surgical treatment of gastric carcinoma.

Gastric cancer has a dismal prognosis in the Western world. In contrast, in Japan where extended lymphadenectomy is the rule in curative gastric cancer surgery, the prognosis is much better. The arguments for and against the adoption of this procedure in the West are presented. This procedure is safe in the hands of experienced surgeons and by improving locoregional control, may improve survival. However, in the absence of controlled data supporting a survival advantage, the excess morbidity and mortality of this extended procedure in the West may not be justified.
