胃癌的早期诊断及手术治疗与提高患者牛存率密切相关。在日本大多数病人常规行根治性胃切除加扩大淋巴结清扫术。然而在西方国家的研究结果却显示其发病率和死亡率均较高，并指出如此高的发病率对患者益处不大。为此，作者研究的目的旨在阐明淋巴结阳性胃癌行根治性胃切除加扩? The early diagnosis and surgical treatment of gastric cancer are closely related to improving the survival rate of cattle. In Japan, most patients routinely undergo radical gastrectomy plus enlarged lymph node dissection. However, studies in Western countries have shown high morbidity and mortality, and pointed out that such a high incidence of disease is of little benefit to patients. To this end, the purpose of the author’s study is to clarify the radical gastrectomy plus enlargement of lymph node positive gastric cancer.
