[摘要] 目的:探讨超声诊断乳腺肿块的应用价值。方法:对75例乳腺良性肿块及恶性肿瘤患者分别进行常规二维超声检查及彩色多普勒检查,并与手术病理检查对照,分析两者不同的声像改变。结果:乳腺良性肿块较恶性在形态、边缘、包膜、声晕、后方回声等声像特征比较,差异有统计学意义(P<0.05),尤其是恶性肿块的微小钙化点检出率48%(20/42),后方衰减45%(19/42),高回声晕33%(14/42),与I级以上血流信号93%(39/42);较良性肿块的微小钙化点检出率12%(4/33),后方衰减18%(6/33),高回声晕54%(18/33),与I级以上血流信号27%(9/33),且差异有统计学意义(P<0.05)。结论:常规二维超声结合彩色多普勒超声检查对乳腺肿瘤的早期检出具有重要价值。

[Abstract] Objective: To evaluate ultrasound diagnosis and pathology diagnosis in patients with breast tumors. Methods: Overall 101 cases with benign or m alignant breast tumors were examined by ultrasound and color Doppler ultrasonography,and the results were compared with the surgical and pathological findings.The different image features between the benign and m alignant breast tumors were analyzed. Results: The benign and m alignant breast tumors were significantly different in shapes, boundary, capsules, sound corona and rear echo(P<0.05).The detection rates of minute calcification, upwards of level Ⅰ blood stream, rear attenuation and high echo corona of m alignant carcinoma were 48%(20/42), 45%(19/42), 33% (14/42) and 93.8%(60/64)markedly higher than those benign tumors,which were 12%(4/33), 18%(6/33), 54%(18/33) and 27.0%(10/37), respectively(P<0.05).Conclusion: The conventional gray scale ultrasound examination is of great significance in the early detection of breast tumors.

乳腺癌是一种严重威胁女性身心健康,甚至危及生命的恶性肿瘤,近年来发病率逐年增加,在欧美西方发达国家,乳腺癌居35~54岁女性人口死亡原因的第一位[1]。中国乳腺癌发病率相对较低,但近年来在大中城市的发病率呈逐渐上升趋势。因而早期发现、早期诊断、早期治疗成为防治乳腺恶性肿瘤的关键所在,尤其对早期乳腺癌的诊断,能显著提高患者的生存率和生存质量。乳腺肿瘤的早期发现及确诊对临床治疗及治疗方式的选择有重要意义,但许多乳腺肿块缺乏特异性的超声影像特征,易造成漏诊和误诊。本文对75例乳腺肿块的声像图与病理结果进行回顾性分析,旨在探讨超声诊断乳腺肿块的临床应用价值。
1 资料与方法
1.1 临床资料
2007年11月~2008年10月,在我院进行乳腺病变切除活检术的患者,术前均行双侧乳腺超声检查,明确显示病变。术后病理诊断乳腺良性及恶性肿块75例,患者均为女性。恶性组:42例,年龄28~75岁,平均52.3岁,其中发病最高年龄组50~59岁,发病率为40.48%;良性组:33例,年龄22~61岁,平均43.4岁,其中发病最高年龄组40~49岁,发病率为42.42%。
