Abstract

We examined the efficacy of extended lymph node dissection for prolonging survival in macroscopically or histologically proven incurable gastric cancer. We analyzed clinicopathologic data on 119 patients with serosally invasive gastric cancer who underwent noncurative gastrectomy, with respect to the relation between the extent of lymphadenectomy and survival benefit. The 5-year survival rate was significantly higher among patients treated with extensive lymphadenectomy (R2/3) compared to simple gastrectomy (R1). Extensive lymphadenectomy significantly prolonged survival time even after noncurative gastrectomy in cases where there was no evidence of hepatic metastasis, peritoneal seeding, or extensive nodal metastasis beyond the tertiary lymph node, and regardless of the extent of direct invasion to adjacent organs. Gastrectomy combined with extended lymphadenectomy and/or resection of adjacent organs is recommended for gastric cancer patients without distant metastasis, even when the operation is histologically noncurative. Gastrectomy and perioperative intensive chemotherapy are called for when patients have distant metastasis.
