In Japan, R2 lymph node dissection is standard practice for all curatively resected gastric cancer patients. From 1969 to 1984, data were collected prospectively to evaluate this procedure and to provide information for a more rational approach to node dissection for each individual case. A total of 3843 cases was included in this study and an evaluation was made of the prognostic variables and lymph node involvement at various locations. Using a computer program, it is possible to compile a group of treated patients, with prognostic variables exactly matching those of an individual patient. Analysis of this group can then give an indication of the extent of lymph node dissection required for an individual patient. This paper gives a demonstration of the structure of such a system by means of an example.
在日本，对所有接受根治性切除的胃癌患者进行R2淋巴结清扫是标准做法。1969年至1984年，前瞻性收集数据以评估该手术，并为针对每个病例更合理地进行淋巴结清扫提供信息。本研究共纳入3843例病例，并对预后变量及不同部位的淋巴结受累情况进行了评估。利用计算机程序，可以编制一组治疗患者，其预后变量与个体患者的完全匹配。然后对该组进行分析，可为个体患者所需的淋巴结清扫范围提供指示。本文通过一个例子展示了这种系统的结构。
