三维超声技术评价胃癌腹腔淋巴结转移的应用价值

目的探讨三维超声技术评价胃癌淋巴结转移的应用价值。方法对95例胃镜病理证实为胃癌的患者进行术前二维、三维超声检查，测量肿瘤长径、胃壁浸润深度和肿瘤体积，分析其与胃癌淋巴结转移的关系。结果95例胃癌患者中，无淋巴结转移24例；淋巴结转移71例，转移性淋巴结数481枚。淋巴结转移组和无淋巴结转移组患者的组织学分级、Borrrnann分型差异均有统计学意义（均P〈0．05），而患者年龄、性别、肿瘤部位差异均无统计学意义（均P〉0．05）。淋巴结转移组和无淋巴结转移组患者的肿瘤体积分别为（26．02±6．87）cm2和（13．11±2．79）cm2，差异有统计学意义（P〈0．05）。淋巴结转移组和无淋...

Summary:目的探讨三维超声技术评价胃癌淋巴结转移的应用价值。方法对95例胃镜病理证实为胃癌的患者进行术前二维、三维超声检查，测量肿瘤长径、胃壁浸润深度和肿瘤体积，分析其与胃癌淋巴结转移的关系。结果95例胃癌患者中，无淋巴结转移24例；淋巴结转移71例，转移性淋巴结数481枚。淋巴结转移组和无淋巴结转移组患者的组织学分级、Borrrnann分型差异均有统计学意义（均P〈0．05），而患者年龄、性别、肿瘤部位差异均无统计学意义（均P〉0．05）。淋巴结转移组和无淋巴结转移组患者的肿瘤体积分别为（26．02±6．87）cm2和（13．11±2．79）cm2，差异有统计学意义（P〈0．05）。淋巴结转移组和无淋巴结转移组患者的肿瘤浸润深度分别为（1．57±0．29）cm和（1．10±O．29）cm，差异有统计学意义（P〈0．05）。而淋巴结转移组和无淋巴结转移组患者的肿瘤长径分别为（4．52±0．73）cm和（4．24±1．04）cm，差异无统计学意义（P〉0．05）。Logisitic回归分析显示，肿瘤体积和浸润深度是胃癌淋巴结转移的独立预测因素（均P〈0．05）。受试者工作特征曲线分析显示，当肿瘤体积为16．8cm。作为判断胃癌淋巴结转移的标准时，其敏感度为90．1％，特异度为95．8％。结论三维超声为术前胃癌体积的测量提供了可能性，肿瘤体积可间接评价胃癌腹腔淋巴结的转移情况。
Bibliography:Objective To investigate the clinical value of three-dimensional uhrasonography （3D- US） in the diagnosis of abdominal lymph node metastasis of gastric carcinoma. Methods A total of 95 patients with gastric cancer diagnosed by gastroscopy and confirmed by pathology after operation were examined by 3D-US preoperatively. The characteristics of gastric carcinoma was assessed using QLAB software. The tumor volume, lesion diameter and invasion depth of gastric cancer were measured. Results All of the 95 subjects were divided into two groups according to their lymph nodes status postoperatively ：group N±, 71 patients with lymph node metastasis; and group NO, 24 patients without lymph node metastasis. The quantitative 3D-US analysis and pathological results of these two groups were compared with each other. The tumor volume of group N± was significantly higher than that of the group NO [ （26.02±6.87）cm3 vs. （13.11± 2.79） cm3,P〈0.05 ], the invasion depth was significantly deeper in the group N± than in the group NO [
