摘　　要：目的:回顾性分析年轻乳腺癌患者超声影像学特征。方法:对手术后组织病理证实的190例女性乳腺癌患者彩色多谱勒超声图像进行回顾性分析。以中老年组(年龄>45岁)乳腺癌作为对照,分析年轻组(年龄≤45岁)乳腺癌超声图像特征。结果:年轻组乳腺癌肿块"边界不清晰"、"边缘毛刺征"比例均低于中老年组乳腺癌,差异均有统计学意义(P<0.05);年轻组乳腺癌"肿块直径≤2 cm"、"血流≥Ⅱ级"、"阻力指数RI≥0.7"及"腋窝淋巴结转移"比例均高于中老年组,差异均有统计学意义(P<0.05);对比"形态不规则"、"内部回声不均匀"、"纵横比>1"、"微小钙化灶"及"后方回声衰减"征象,2组间差异均无统计学意义(P>0.05)。结论:年轻乳腺癌和中老年乳腺癌超声图像特征比较在边界不清晰、边缘毛刺征、肿块大小、血流分级、阻力指数和腋窝淋巴结肿大等方面存在差异,在实际应用中重视这些特征可提高年轻乳腺癌超声诊断准确性。Objective ： To analyze the uhrasonographic features of breast cancer in young women.Methods ： Color Doppler ultrasound images were retrospectively analyzed in 190 cases of breast cancer confirmed pathologically.The differences of ultrasound characteristics were compared between the young group （ ≤45 years）and the middle / elder group （ 〉45 years）.Results： The ratios of ＂irregular morphology＂ and ＂burrs margin＂ of the tumors in the young group were lower than those in the middle/elder group （P〈0.05） .Patients in the young group had higher ratios of ＂diameter of tumor ≤2 cm＂ ,＂ blood- stream≥ grade Ⅱ ＂ ,＂ resistance index ≥ 0.7＂ and ＂lymph nodes metastasis＂ than the middle/elder group （P〈 0.05） , yet the difference was not significant between groups regarding the tumor shape, internal echo, micro-calcification, posterior echo and transverse-longitudinal axis ratio （L/T） （P〉 0.05 ）. Conclusion ： Young women are different from the middle/elder ones in uhrasonographic properties as aforementioned, by which the characteristics can be conducive to accurate diagnosis of breast cancer in young women.
