彩色多普勒超声在早期乳腺癌诊断中的应用价值

目的 探讨彩色多普勒超声在早期乳腺癌中的声像特点及其诊断意义.方法 对46例经术后病理证实的早期乳腺癌超声图像特点进行回顾性分析,结合同期262例经病理证实的良性乳腺病例,计算超声对早期乳腺癌诊断的灵敏度、特异度及诊断符合率,并与其他检查相比较.结果 在早期乳腺癌中,超声下肿块的边缘征象发生率较低,血流信号检出率低于其他各期乳腺癌,肿块内点状钙化及肿块纵横径比有一定诊断意义.本组病例超声灵敏度为78.3％ (36/46);特异度为84.4％ (221/262);假阳性率15.6％ (41/262);假阴性率21.7％ (10/46);诊断符合率为83.4％ (257/308).比积数为19.40.结论 彩色多普勒超声在早期乳腺癌中具有独特的声像特点,诊断符合率较高,其应用对早期乳腺癌的诊断有很大价值.

The value of color Doppler ultrasonography for diagnosis of early stage breast cancer

Objective To investigate the image feature and diagnostic value of color Doppler ultrasonography in early stage breast cancer.Methods 46 patients with early stage breast cancer were all confirmed by surgery and pathological examination.Their ultrasonographic images were analyzed.Compared with 262 benign breast disease patients,Sensitivity,specificity and accuracy rate of ultrasonography in early stage breast cancer were calculated and compared with other examination.Results In ultrasonographic images of early stage breast cancer tumor,the incidence rate of tumor silhouette sign was lower.Blood flow signal detection rate was lower than other stage breast cancer.Punctuate calcification and longitudinal-transverse diameter ratio of tumor had diagnostic value.Sensitivity,specificity,mistake diagnostic,omission diagnostic and accuracy rate of ultrasonography was 78.3%(36/46),84.4%(221/262),15.6%(41/262) 21.7%(10/46) and 83.4%(257/308),OP was19.40.Conclusion Color Doppler ultrasonography has distinct image feature in early stage breast cancer.Diagnose accordance rate is much higher.Ultrasonography has great value in diagnosing early stage breast cancer.
