摘　　要：目的总结分析男性乳腺癌的超声特征,分析脂肪层厚度与乳腺癌发生的关系。方法对患乳腺癌的男性患者进行详细超声检查,检查部位包括双乳、腺体周围淋巴引流区及胸壁(范围为双侧腋中线间锁骨上区至肋弓),记录其声像特征,测量乳腺癌患者的胸壁及脂肪层厚度并与正常体质量[(身高cm-100)×0.9为标准体质量(kg),正负10%为正常体质量]健康体检者进行对比。结果①男性乳腺癌超声影像特征多见:边缘毛刺、内部回声不均、钙化、后方声衰、彩色多普勒血流丰富等。②肿块最大径、血流分级与淋巴结转移有关,肿块越大、血流分级越高,转移癌的发生率越高。肿块的边界、内部回声、有无钙化及后方声衰淋巴结转移者与无淋巴结转移者差异无统计学意义(P>0.05)。③乳腺癌组的胸壁及胸壁脂肪层厚度与健康对照组不同,胸壁厚度分别为(1.37±0.12)cm vs(1.31±0.08)cm(P<0.05),胸壁脂肪层厚度为(0.89±0.09)cm vs(0.86±0.06)cm(P<0.05)。结论男性乳腺癌超声特征典型,发生淋巴结转移较早,乳腺癌发生与脂肪密切相关,有必要进一步总结乳腺癌发生概率与脂肪层厚度的关系,为男性乳腺癌的发生提供预警和风险评估。Objective To summarize and analyze ultrasonic image signature in male breast cancer, and analyzethe relationship between development of breast cancer and thickness of fat layer. Methods The breast and chest wall of the male patients with breast cancer were examined carefully by ultrasound （ range： between bilateral axillary midline, from supraclavicular to rib bow） , ultrasonic image signature were recorded. The thickness of chest wall and fat layer of the breast cancer patients were measured and compared with normal body mass （[body height cm- 100] ×0.9 is standard body mass, positive negative 10% is normal body mass） in health examination subjects（health subjects）. Results ① Ultrasonic image signature of male breast cancer showed edge burr,unevenness internal echo,calcification, rear sound failure, rich blood flow, and so on② Mass maximum diameter and blood flow classification related to lymph node metastatic carcinoma（ P 〈0.05）. The mass was bigger and the grade of blood flow higher, the incidence of metastatic carcinoma higher. Edge, internal echo, calcification and rear sound failure did not relate to lymph node metastatic carcinoma（ P〉0.05）; ③The thickness of chest wall and fat layer were different between breast cancer patients and health subjects（ P 〈0.05）, respectively the thickness of chest wall was （ 1.37± 0.12） cm vs （ 1.31 ±0.08） cm and fat layer （0.89±0.09） cm vs （0.86±0.06） cm. The two indexes related to the development of breast cancer. Conclusion Ultrasonic image signature is obvious in male patients with breast cancer,lymph node metastatic carcinoma occurs early. It is necessary to summarize the relationship between the incidence of metastatic carcinoma and the thickness of fat layer,apply early warning and risk assessment for male breast cancer.
