To date, no studies have been performed on staging based on the lymph node ratio (LNR) in elderly patients with gastric cancer who may require limited lymph node (LN) dissection due to morbidity and tissue fragility. We aimed to develop a new N staging system using the LNR in elderly patients with gastric cancer.

基于淋巴结比率的老年患者胃癌分期新方法。

迄今为止，尚未对老年胃癌患者进行基于淋巴结比率 (LNR) 的分期研究，这些患者可能由于发病率和组织脆性而需要有限的淋巴结 (LN) 清扫。我们的目标是在老年胃癌患者中使用 LNR 开发一种新的 N 分期系统。
