摘要
目的 探讨胃肠充盈超声造影预测早期胃癌(EGC)淋巴结转移的价值.方法 选取接受胃肠充盈超声造影检查并经胃镜诊断术后病理证实EGC 患者 63 例,对病灶及周围正常胃壁勾画感兴趣区(ROI),获取病灶峰值强度(PKI)、上升时间(RT),根据术后病理结果分为淋巴结转移组N1(31 例)和非淋巴结转移组N0(32 例),比较两组胃癌充盈超声造影参数差异及与淋巴结转移的关系.结果 与N0 组EGC 患者相比,N1 组EGC 患者在一般资料与病灶浸润深度方面差异无统计学意义(P>0.05).N1 组EGC 患者病灶PKI 值高于N0 组,而RT 值短于N0 组,其差异均具有统计学意义(P<0.05).PKI、RT 值预测EGC 患者淋巴结转移ROC 曲线下面积分别为 0.930、0.762.结论 胃肠充盈超声造影对术前无创定量评估EGC 患者淋巴结转移有一定的诊断价值.
Abstract
Objective To investigate the value of gastrointestinal filling ultrasound in predicting lymph node metastasis in early gastric cancer(EGC).Methods 63 patients with EGC who underwent gastrointestinal filling contrast-enhanced ultra-sound examinationwere collected and were diagnosed by gastroscopy and confirmed by postoperative pathology.The area of inter-est(ROI)of the lesion and surrounding normal gastric wall was drawn,the peak intensity(PKI)and rise time(RT)of the lesion-were obtained and patients were divided into lymph node metastasis group N1(31 cases)and non lymph node metastasis group N0(32 cases)based on postoperative pathological results andthe differences in contrast-enhanced ultrasound parametersand their relationship with lymphnode metastasis were compared between the two groups.Results Compared with the groupN0 of EGC patients,there was no significant difference in general information and depth of lesion infiltration among the group N1of EGC patients(P>0.05).The PKI value of the lesion in the groupN1 of EGC patients was higher than that in the groupN0,while,the RT value was shorter than that in the groupN0,and the differences were statistically significant(P<0.05).PKI and RT val-ues predicted that the area under the Receiver operating characteristic of lymph node metastasis in EGC patients was 0.930 and 0.762,respectively.Conclusion Gastrointestinal filling contrast has certain diagnostic value for the non-invasive quantitative evaluation of lymph node metastasis in patients with EGC before surgery.
