【摘要】 目的:研究进展期胃窦癌No.14v组淋巴结的转移规律。方法:通过对50例进展期胃窦癌患者行D2根治术,检测No.14v组淋巴结转移情况、No.6淋巴结转移情况、肿瘤浸润深度、肿瘤TNM分期、肿瘤直径及肿瘤分化程度,然后统计分析No.14v组淋巴结转移与上述其他检测指标之间的关系及术前CT检查的准确率。结果:术前CT检查发现No.14v组淋巴结转移阳性率为2%,假阴性率为12%。进展期胃窦癌No.14v组淋巴结转移率为12%。No.6淋巴结转移阳性者No.14v组淋巴结转移率24%,No.6淋巴结转移阴性者No.14v组淋巴结转移率3%。No.14v组淋巴结转移与No.6淋巴结转移、肿浸润深度、肿瘤TNM分期及肿瘤直径有关(P<0.05),而与肿瘤分化程度无关(P>0.05)。结论:CT对No.14v组淋巴结转移的诊断准确性不高,进展期胃窦癌No.14v组淋巴结转移率较高,No.6淋巴结转移阳性者No.14v组淋巴结转移率高。更多还原

【Abstract】 Objective:To discuss the patterns of No.14v lymph nodes metastasis in advanced gastric antral cancer.Methods:50 cases of advanced gastric antral cancer patients underwent D2 radical resection.To detect No.14v lymph nodes metastasis,No.6 lymph nodes metastasis,depth of invasion,TNM staging,tumor diameter,and the degree of tumor differentiation,and analyze the relationships between No.14v lymph nodes metastasis and other detect indexes mentioned above,and the rate of accuracy of CT before surgery.Results:Detected by CT before surgery,the positive rate of No.14v lymph nodes metastasis was 2%,and false negative rate was 12%.The rate of No.14v lymph nodes metastasis in advanced gastric antral cancer was 12%.The rate of No.14v lymph nodes metastasis with positive No.6 lymph nodes metastasis was 24%,and the rate of No.14v lymph nodes metastasis with negative No.6 lymph nodes metastasis was 3%.No.14v lymph nodes metastasis was related to No.6 lymph nodes metastasis,depth of invasion,TNM staging,tumor diameter(P<0.05),and was nothing to do with the degree of tumor differentiation.Conclusion:The accuracy of the diagnosis of No.14v lymph nodes metastasis by CT is low,the rate of No.14v lymph nodes metastasis in advanced gastric is high,and the rate of No.14v lymph nodes metastasis with positive No.6 lymph nodes metastasis is high.更多还原
