目的比较高频彩超与钼靶X线诊断乳腺癌的临床价值,为临床上诊断乳腺癌提供方法。方法选择经手术或超声引导下穿刺活检病理学证实为乳腺癌的54例患者(均为单侧病灶)为研究对象。所有患者均同时接受乳腺高频彩超和钼靶X线检查,比较高频彩超和钼靶X线对乳腺癌的显示情况。结果术前高频彩超检出51例病灶,诊断符合率为94.44(51/54);所有灶均显示出肿块并可见低回声表现,其中肿块形态多变,主要有边缘针刺样改变24例,蟹足样改变18例,分叶状12例。其中肿块伴钙化者12例,肿块后声衰减24例。血流丰富者44例,未见明显血流7例;腋窝可见肿大淋巴结19例,未见肿大淋巴结32例。术前钼靶X线共检出42例,诊断符合率为77.78(42/54),表现为肿块39例,钙化灶41例,导管征28例,皮肤浸润11例,腋窝淋巴结8例。高频彩超对于肿块、腋窝淋巴结、导管和皮肤浸润的显示率明显高于钼靶X线,而钼靶X线对于钙化灶的显示率明显优于高频彩超,差异均有统计学意义(P<0.05);高频彩超诊断乳腺癌的准确率明显高于钼靶X线,差异有统计学意义(P<0.05)。结论高频彩超与钼靶X线对乳腺癌的显示各有优势,均可作为诊断乳腺癌的检查手段,二者联合可以提高乳腺癌的诊断准确性。
Objective To compare the clinical value of high frequency color Doppler ultrasonography and molybdenum target X-ray in the diagnosis of breast cancer and provide a method for clinical diagnosis of breast cancer. Methods Fifty-four patients (all unilateral lesions) confirmed by breast biopsy with biopsy guided by surgery or ultrasound were selected as the study objects. All patients underwent both high-frequency breast ultrasound and mammography X-ray examination. The comparison between high-frequency ultrasound and mammography X-ray on breast cancer was performed. Results Preoperative high frequency ultrasound detected 51 lesions, the diagnostic coincidence rate was 94.44 (51/54); all lesions showed low echogenicity and mass, in which the mass of the tumor varied. There were 24 cases of marginal acupuncture , Crab foot-like change in 18 cases, lobulated in 12 cases. Among them, lumps and calcifications were found in 12 cases, and the sound attenuation in the lumps was 24 cases. Blood rich in 44 cases, no significant blood flow in 7 cases; axillary lymph nodes seen in 19 cases, no enlarged lymph nodes in 32 cases. Forty-two cases of preoperative molybdenum target X-ray were detected. The diagnostic coincidence rate was 77.78 (42/54). There were 39 cases of mass, 41 cases of calcification, 28 cases of catheterization, 11 cases of skin infiltration and 8 cases of axillary lymph node. The frequency of high frequency ultrasound for the tumor, axillary lymph nodes, ductal and skin infiltration was significantly higher than the molybdenum target X-ray, while the molybdenum target X-ray calcification was significantly better than high frequency color Doppler ultrasound, the differences were statistically significant (P <0.05). The accuracy of high-frequency color Doppler ultrasound in the diagnosis of breast cancer was significantly higher than that of molybdenum target X-ray, the difference was statistically significant (P <0.05). Conclusion High-frequency color Doppler ultrasound and molybdenum target X-ray show the advantages of breast cancer, can be used as a diagnostic tool for breast cancer detection, the combination of the two can improve the diagnostic accuracy of breast cancer.
