| pubmed-article:7676699 | pubmed:abstractText | The controversy over the value of extended lymph node dissection for treatment of gastric cancer is fiercely debated. Whereas Japanese surgeons claim that the superior survival rates in their series are due to extensive resection (D2 resection), many Western authorities believe that their results only reflect differences in the prevalence of prognostic factors, inconsistencies between Japanese and Western staging systems, and the phenomenon of "stage migration," which occurs with extensive resection. Two small randomized prospective trials from Hong Kong and Cape Town showed a tendency toward high morbidity with extensive lymph node dissection but no survival benefit. In contrast, the recently completed prospective German Gastric Carcinoma Study demonstrated a clear survival advantage with D2 resection for tumor stages II and IIIa with no increase in perioperative morbidity or mortality. The long-term results of the still ongoing randomized MRC and Dutch trials are therefore eagerly awaited. | lld:pubmed |
