目的探讨乳腺钼靶联合彩色多普勒超声诊断T1期乳腺癌的价值。方法采用乳腺钼靶、彩色多普勒超声及两者联用对57例女性T1期乳腺癌患者进行术前检查,其中48例行乳腺钼靶检查,42例行彩色多普勒超声检查,37例行两者联合检查,回顾比较三种检查方法的差异。结果乳腺钼靶、彩色多普勒超声的诊断符合率分别为62.5%、57.1%,两者联合的诊断符合率86.5%,与前者相比差异有统计学意义(P<0.05)。≥45岁T1期乳腺癌钼靶诊断符合率为75.0%,而<45岁T1期乳腺癌的符合率为37.5%,两者相比差异具有统计学意义(P<0.05)。结论乳腺钼靶和彩色多普勒超声检查各有优缺点,联合应用诊断T1期乳腺癌的符合率均高于单行钼靶或彩色多普勒超声检查,能明显提高早期乳腺癌诊断的阳性率,乳腺钼靶对乳腺癌的检出率受年龄因素影响较大。 Objective To investigate the value of mammography combined with color Doppler ultrasonography in the diagnosis of T1-stage breast cancer. Methods Fifty-seven female patients with stage T1 breast cancer underwent preoperative mammography, color Doppler ultrasonography and their combination. Forty-eight patients underwent mammography, 42 underwent color Doppler sonography, 37 Routine joint inspection of the two, review the differences between the three methods of inspection. Results The diagnostic rates of mammography and color Doppler were 62.5% and 57.1%, respectively. The coincidence rate of mammography and color Doppler ultrasound was 86.5%, which was significantly different from the former (P <0.05). The coincidence rate of mammographic diagnosis of T1-stage breast cancer ≥45 years old was 75.0%, while the coincidence rate of T1-stage breast cancer of 45-year-old was 37.5%. There was significant difference between them (P <0.05). Conclusions Both mammography and color Doppler ultrasonography have their own advantages and disadvantages. The coincidence rates of combined application of T1 and T2DM in diagnosis of T1 breast cancer are higher than that of single mammography or color Doppler ultrasound, which can significantly improve the positive rate of diagnosis of early breast cancer , Breast mammography detection rate of breast cancer by age factors.
