目的研究应用Maruyama软件术前预测胃癌淋巴结转移范围的可靠性与可行性。方法分别对246例和134例胃癌患者进行回顾性和前瞻性研究。将患者性别、年龄、肿瘤Borrmann分型、组织学类型、浸润深度、部位、大小等预后因素输入计算机,应用Maruyama软件对淋巴结转移范围进行分析,再将其结果与术后病理诊断进行对比研究。结果本组胃癌淋巴结转移判断的正确率较高。在回顾性研究中,N1为890%、N2为874%、N3为955%,总体达890%;在前瞻性研究中,上述各组淋巴结转移的术前预测正确率分别达873%、821%、888%和873%。结论通过Maruyama软件分析,术前预测胃癌淋巴结转移可达较高正确率,但为进一步提高其临床应用价值,还应改善术前判断肿瘤浸润深度的可靠性。
Objective To study the reliability and feasibility of predicting lymph node metastasis of gastric cancer by Maruyama software. Methods A retrospective and prospective study was performed on 246 patients and 134 patients with gastric cancer. The patient’s gender, age, tumor Borrmann type, histological type, depth of invasion, location, size and other prognostic factors were entered into the computer. Maruyama software was used to analyze the range of lymph node metastasis, and the results were compared with postoperative pathological diagnosis. Results The correct rate of lymph node metastasis was higher in this group. In the retrospective study, N1 was 890%, N2 was 874%, N3 was 955%, and the total was 890%. In the prospective study, the accuracy of preoperative prediction of lymph node metastases in the above groups was respectively 87.8% and 82.1%. 888% and 873%. Conclusions Maruyama software analysis predicts the accuracy of preoperative lymph node metastasis in gastric cancer. However, in order to further improve its clinical application value, the reliability of judging the extent of tumor invasion before operation should be improved.
