Objective:
To examine the relationship between the dissected lymph-node number and the prognosis in D(2) gastrectomy for gastric cancer.
Methods:
From January 1996 to January 2005, 457 patients with primary gastric cancer undergone gastrectomy with different extent of lymphadenectomy in our hospital were followed-up in term of prognostic benefit.
Results:
In lymph-node metastasis group, the 1-, 3-, 5-year survival rates were 82.4%, 49.0%, 33.4% with dissection of >20 nodes and 71.5%, 49.7%, 40.1% with dissection of 16-20 nodes. In the group without lymph-node metastasis, the 1-, 3-, 5-year survival rates were 98.2%, 92.7%, 84.7% with dissection of >20 nodes and 94.0%, 89.7%, 81.4% with dissection of 16-20 nodes. Whether or not it had lymph-node metastasis, the survival curve failed to show any significant difference with regard to the extent of lymph node dissection.
Conclusions:
As to lymphadenectomy for gastric cancer, it is enough to excise the lymph node between 16 and 20. The number of excised lymph node should not be overemphasized unless it is metastasized.

The lymphatic system has two main functions: to return extracellular fluid back to the venous circulation and to expose antigenic substances to the immune system. As the collected fluid passes through lymphatic channels on its way back to the systemic circulation, it encounters multiple nodes consisting of highly concentrated clusters of...
