Objective: To analyze the ultrasonographic 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", "bloodstream≥ gradeⅡ", "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 ultrasonographic properties as aforementioned, by which the characteristics can be conducive to accurate diagnosis of breast cancer in young women.%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.
