X线摄影、彩色多普勒超声和立体定位穿刺对早期乳腺癌的诊断价值

目的 探讨X线摄影、彩色多普勒超声（简称彩超）和立体定位穿刺对早期乳腺癌的诊断价值，提高其诊断率。方法 55例早期乳腺癌和25例乳腺良性病变均行两侧X线摄影、彩超检查，再经立体定位穿刺，作病理学检查。结果 在55例早期乳腺癌中，X线钼靶摄影诊断早期乳腺癌45例，其敏感性和特异性分别为82．0％和88．0％；彩超诊断早期乳腺癌43例，其敏感性和特异性分别为78．2％和84．0％，准确性为80．0％；立体定位穿刺诊断早期乳腺癌53例，其敏感性和特异性分别为96．4％和92．0％，准确性为95．0％，无假阳性。综合影像诊断早期乳腺癌54例，其敏感性和特异性分别为98．2％和96．0％，准确性为97．5％。结论X线摄影、彩超和立体定位穿刺联合应用，可提高早期乳腺癌诊断的敏感性和准确性。

The value of mammography,color Doppler ultrasound and biopsy in diagnosis of early breast cancer

Objective To study the diagnos tic value of mammography, color Dopp ler ultrasound and biopsy in early breast cancer and to evaluate its diagnostic accuracy. Methods 55 patients with breast cancer an d 25 patients with benign breast masses, proved pathologically, were checked by mammogra phy, color Doppler ultrasound and biopsy. Results Mammography demonstrated bre ast cancer in 45 cases, the sensitivity and specificity were 82.0% and 88.0%, re spectively, with the accuracy of 83.8%; Color Doppler ultrasound revealed breas t cancer in 43 cases, the sensitivity, specificity and accuracy were 78.2%, 84 .0% and 80.0%; Biopsy demonstrated breast cancer in 53 cases, the sensitivity, specificity and accuracy were 96.4%, 92.0% and 95.0%. When ultrasound, mammagrap hy and biopsy were combined together, the sensitivity, specificity and accuracy were 98.2%, 96.0% and 97.5%. Conclusion Mammography, color Dopp ler ultrasound combined with biopsy can increase the diagnostic sensitivity and accuracy of ear ly breast cancers.
