Luminal B-HER-2阴性乳腺癌和三阴型乳腺癌X线征象比较

Comparison Analysis of X-ray Signs Signs between Luminal B-HER-2(-)Breast Cancer and Triple negative Subtype Breast Cancer

目的探讨Luminal B-HER-2阴性型乳腺癌和三阴型(TN)乳腺癌临床病理特征及X线征象的差异。方法搜集行全数字化乳腺X线摄影并手术病理证实乳腺癌476例,对X线征象进行统计分析。结果肿块形态:Luminal B-HER-2阴性型不规则较多,TN型椭圆形较多。肿块密度:Luminal B-HER-2阴性型密度增高较多。肿块边缘:Luminal B-HER-2阴性型毛刺较多,TN型模糊较多。肿块长径:Luminal B-HER-2阴性型2~5 cm较多,TN型大于5 cm较多。钙化形态:Luminal B-HER-2阴性型细小多形性较多,TN型模糊不定形较多。其他征象:Luminal B-HER-2阴性型在淋巴结转移较多,皮肤乳头改变较多。象限:Luminal B-HER-2阴性在外上象限较多。结论Luminal B-HER-2阴性型乳腺癌和TN型乳腺癌在影像征象上有差异。

Objective To explore the differences in clinicopathological characteristics and X-ray signs of Luminal B-HER-2(-)breast cancer and triple negative breast cancer.Methods A total of 476 cases of breast cancer were confirmed by digital mammography and confirmed by surgical pathology.The X-ray signs were statistically analyzed.Results Mass morphology:Luminal B-HER-2(-)type had more irregularities,and triple-negative type had more oval shapes.Mass density:Luminal B-HER-2(-)type had increased density.Lump margin:Luminal B-HER-2(-)type has more burrs and triple-negative type has more blur.Tumor length:Luminal B-HER-2(-)type is more in 2-5 cm,and triple-negative type is more than 5 cm.Calcification morphology:Luminal B-HER-2(-)type has more small polymorphism,and more triple negative ambiguous indefinite shape.Other signs:Luminal B-HER-2(-)type has more metastasis in lymph nodes and more changes in skin and nipple.Quadrant:Luminal B-HER-2(-)has more upper quadrants.Conclusion Luminal B-HER-2(-)breast cancer and triple negative breast cancer have different imaging signs.
