乳腺X线摄片在乳腺癌腋窝淋巴结转移的诊断价值

摘要

Objective To evaluate diagnostic value of mammography in axillary lymph node metastasis of breast cancer.Methods Preoperative mammography was employed to 165 patients of breast cancer,evaluation of mammographic diagnostic grade was conducted , and the highest density or the maximum size of axillary lymph node in each patient underwent pathological examination,and the results were compared with that of axillary lymph nodes in each patient after surgery.Results Among 165 patients with breast cancer,82 cases of axillary lymph nodes metastasis were uncovered by postoperative pathological examination.There were 56 pathologically confirmed cases of axillary lymph nodes metastasis among 106 cases of breast cancer that were detected by mammography.There were further 26 confirmed cases out of 59 that were missed by mammography.The probability of the occurrence of axillary lymph node metastasis seems to correlate with the density and the shortaxis diameter size of lymph nodes as well as the grade of diagnostic mammography.Conclusion Mammography is a simpy and basic radialogic method to evaluate metastasis of axillary lymph nodes in breast cancer, which could be benefit to a comprehensive assessment of patients before surgery.%目的 评估X线摄片在诊断乳腺癌腋窝淋巴结转移中的应用价值.方法 对165例乳腺癌患者进行术前X线摄片,对其进行乳腺X线诊断分类评估,取患者腋窝淋巴结密度最高或体积最大一枚进行病理检查,将其与手术后的病理结果对照分析.结果 165例乳腺癌患者术后病理检查提示腋窝淋巴结转移82例;X线能显示腋窝淋巴结的106例中病理证实有腋窝淋巴结转移56例,不能显示腋窝淋巴结的59例中病理证实有腋窝淋巴结转移26例;腋窝淋巴结转移的可能性与淋巴结密度、短径大小以及乳腺X线诊断分类相关.结论 乳腺X线摄片是判断乳腺癌腋窝淋巴结有无转移简便而基本的影像学检查方法,有利于患者的术前全面评估.
