摘要
目的:评价X线钼靶片术前评估乳腺癌腋窝淋巴结转移的应用价值。方法:对77例乳腺癌患者进行术前钼靶X线检查,观察肿块及腋窝淋巴结的形态、大小,与术后病理进行对照分析。结果:77例中46例片内检出有淋巴结,敏感度为59.7%,共显示淋巴结94枚,短径在0.6cm-2.8cm,平均1.1cm。其中30例所显示58枚淋巴结病理证实无转移,直径均在2.0cm以下,形态呈圆形或椭圆形,边缘光滑,边界清楚,密度不均匀,中心呈稍低密度,周边密度高,呈壳状改变;16例所见36枚淋巴结病理证实有转移,直径均在0.8cm以上,边缘不规则有分叶、边界不清楚,淋巴结密度均匀呈实性无脂肪浸润。并且对淋巴结直径进行统计学分析,转移组与非转移组之间有差别。结论:肿瘤直径对判定乳腺癌淋巴结是否有转移无意义。淋巴结的大小与是否转移有一定关系,当淋巴结最小径大于0.8cm时,参考其边缘、形态、密度的相应改变综合考虑淋巴结转移可能。
Objective： To evaluate the value of molybdenum target radiography in preoperative appraisal of metastasis axillary lymph nodes in breast cancer. Methods ： Total of 77 patients of breast cancer underwent breast molybdenum target radiography. The shape and size of axillary lymph nodes and tumors were observed, and contrasted with pathological diagnosis. Results： There were 94 axillary lymph nodes in 46 cases, sensitivity was 59.7%. The short diameter was from 0.6cm to 2.8cm. Average diameter 1. 1cm. Among them, 58 axillary lymph nodes in 30 cases, with round or ellipse, smooth edge, clear boundary and uneven density, were confirmed nulli - metastatic. Their diameter was all less than 2.0cm. 36 axillary lymph nodes in 16 cases, with irregularity edge, unclear boundary and even density, were confirmed metastatic. Their diameter all more than 0.8cm. Furthermore, there was statistics difference in diameter of axillary lymph nodes between the two groups. Conclusion ： The diameter, of axillary lymph nodes had value in appraisal of metastasis lymph nodes in breast cancer. For the nodes more than 0.8cm, the possibility of metastasis should be considered.
