目的通过分析胃癌原发灶的声像图表现,探讨胃癌原发灶声像图特征与淋巴结转移的相关性。方法回顾性分析155例胃癌患者的声像图表现,采用单因素分析、多因素Logistic回归分析的方法,分别检验胃癌原发灶的最大径、部位、血流丰富程度、浸润深度、Borrmann分型与淋巴结转移的相关性。结果依据单因素分析,胃癌癌肿浸润深度较深,血流较丰富,肿瘤直径>5cm者,对应淋巴结转移率较高(P<0.05);依据多因素分析,胃癌癌肿最大径、浸润深度及血流特征与淋巴结转移明显相关;结论依据胃癌原发灶声像图特征,术前预评估淋巴节转移的可能性具有重要临床意义。
Objective To analyze the correlation between sonographic features of primary gastric cancer and lymph node metastasis by analyzing the sonographic features of primary gastric cancer. Methods A retrospective analysis of 155 cases of gastric cancer patients with sonography, univariate analysis, multivariate logistic regression analysis of the method, respectively, the maximum diameter of gastric cancer, location, degree of blood flow, depth of invasion, Borrmann type Correlation with lymph node metastasis. Results According to univariate analysis, the depth of invasion of gastric cancer was deeper and the blood flow was richer. The diameter of tumor was larger than 5cm, which corresponded to the higher rate of lymph node metastasis (P <0.05). According to multivariate analysis, And blood flow characteristics were significantly correlated with lymph node metastasis.Conclusion According to the characteristics of primary gastric cancer sonography, preoperative assessment of the possibility of lymph node metastasis has important clinical significance.
