背景：本研究的目的是明确胃癌患者转移淋巴结（RML）比例的结果。方法：对650例接受D2根治性胃切除术的胃癌患者的术后生存情况进行RML的分析。分析了 N1 站和所有（N1 和 N2）站的位置、数量和 RML。从分期准确性和患者生存的角度对这些数据进行比较。结果：RML分类如下：RML 0，无受累； RML 1、0 至。 1; RML 2，A 至 0.25； RML 3，大于或等于 25。按 RML 分层的 5 年生存率为 RML 0、86%； RML 1，68%； RML 2，35%； RML 3，16%。 Cox模型将所有淋巴结转移分类方法识别为每次计算中的独立预后指标。然而，第二次 Cox 回归显示，RML 是三种方法中唯一的独立预后因素（P
Background: The purpose of this study was to clarify the outcome of the ratio of the metastatic lymph nodes (RML) in gastric cancer patients.Methods: The postoperative survival of 650 patients with gastric cancer who underwent D2 curative gastrectomy was analyzed with regard to the RML. The location, number, and RML in the N1 station and in all (N1 and N2) stations were analyzed. These data were compared from the viewpoints of staging accuracy and patient survival.Results: The RML was classified as follows: RML 0, no involvement; RML 1, 0 to. 1; RML 2, A to .25; and RML 3, greater than or equal to.25. The 5-year survival rates stratified by RML were RML 0, 86%; RML 1, 68%; RML 2, 35%; and RML 3, 16%. Cox model identified all methods of classifying lymph node metastases as independent prognostic indicators in each calculation. However, a second Cox regression revealed that RML was the only independent prognostic factor among the three methods (P
