Maruyama软件术前预测胃癌淋巴结转移的前瞻性研究

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和可行性.方法]选择2002年1月～2004年6月问施行根治术的胃癌病人166例进行前瞻性研究.将患者性别、年龄、Borrmann分型、组织学类型、浸润深度、肿瘤部位及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,并与术后病理诊断结果比较.结果]Maruyama软件对各站淋巴结转移的术前预测准确率分别为N1:82.2%,N2:89.0%,N3:95.8%.结论]Maruyama软件术前预测胃癌淋巴结转移率准确率较高,如能进一步提高术前对浸润深度的判断,将有望增加该软件的临床使用价值.

Prospective Study of Preoperative Assessment of Lymph Node Metastasis in Patients with Gastric Cancer by Maruyama Computer Program

Purpose]To evaluate the reliability and the feasibility of the application of Maruyama computer program to the preoperative assessment of lymph node metastasis in patients with gastric cancer.Methods]Computer-aided preoperative predictions were determined prospectively using prognostic factors of sex, age, Borrmann classification, histology, depth of wall penetration, location and diameter of the tumor. Data were collected from 166 patients with radical resection from January 2002 to June 2004. The predicated results were compared with the postoperative pathological findings. Results] The prediction of node metastases was highly accurate with lymph nodes N1, 82.2%; N2, 89.0%; N3, 95.8%. Conclusions] Maruyama computer program provides higher accuracy for preoperative assessment of lymph node metastasis in patients with gastric cancer. The application value will be further increased if invasive depth could be assessed preoperation.
