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 5 5例早期乳腺癌和 2 5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 5 5例早期乳腺癌中 ,X线钼靶摄影诊断早期乳腺癌4 5例 ,其敏感性和特异性分别为 82 0 %和 88 0 % ,准确性为 83 8% ;彩超诊断早期乳腺癌 4 3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 5 3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 5 4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。
Objective To investigate the diagnostic value of X-ray photography, color Doppler ultrasound (abbreviated as color Doppler ultrasound) and stereotactic puncture for the diagnosis of early breast cancer, and improve the diagnostic rate. Methods Fifty-five cases of early breast cancer and 25 cases of benign breast lesions were examined by X-ray photography and color ultrasonography on both sides. Then stereotactic puncture was performed for pathological examination. Results In 55 cases of early breast cancer, X-ray molybdenum target photography was used to diagnose 45 cases of early-stage breast cancer. Their sensitivity and specificity were 82.0 % and 88.0 %, respectively, and the accuracy was 83.8%. Ultrasonography was used to diagnose early breast cancer. The sensitivity and specificity of cancer were 43.8%, and the accuracy was 80.0%. Stereotactic puncture was used to diagnose 53 cases of early-stage breast cancer. The sensitivity and specificity were 96.4%. And 920%, with an accuracy of 95%, no false positives. Comprehensive imaging diagnosis of early breast cancer in 54 cases, the sensitivity and specificity were 98 2% and 96%, respectively, with an accuracy of 97.5%. Conclusion The combined use of X-ray radiography, color ultrasound and stereotactic puncture can improve the sensitivity and accuracy of early breast cancer diagnosis.
