Radical surgery for early gastric cancer.

The role of radical surgery for early gastric cancer has become a topic of considerable debate. Despite excellent results from Japan and several retrospective and uncontrolled trials, results from two large prospective randomized trials appear to demonstrate no benefit from D2 compared to the D1 resections. These trials have prompted a move away from radical lymph-node dissection. We argue that this reasoning is flawed and based not on the lack of efficacy of the D2 resection but in an attempt to reduce post-operative mortality and morbidity. Post-operative complications are largely a result of distal pancreatectomy and splenectomy and the relative inexperience of surgeons performing the operations. By preserving these organs and concentrating surgery to specialized centres the complication rate of radical surgery can be significantly reduced to approximate that of non-radical surgery. Lymph-node metastasis to the N2 nodes in early gastric cancer has been shown to be as high as 23%. Non-radical surgery poses significant risks of leaving residual disease. Radical surgery must remain the operation of choice if non-curative surgery for a curable condition is to be avoided.
