146例I期乳腺癌的钼靶、B超与病理对照分析

The value of the combination of mammography and ultrasonography in detection of the 146 cases with stage Ⅰ breast cancer

目的:探讨钼靶和B超对I期乳腺癌的诊断价值。方法:收集146例I期乳腺癌(病灶直径≤2.0 cm)的钼靶和B超的影像学资料,与手术病理作对照分析。结果:病灶直径≤1.0 cm的Ⅰ期乳腺癌B超与钼靶的检出率差异无统计学意义(P>0.05),1.0 cm<病灶直径≤2.0 cm的Ⅰ期乳腺癌B超与钼靶的检出率差异有统计学意义(P<0.05),B超检出率明显高于钼靶二者联合应用,诊断符合率为79.45%。结论:对临床疑为I期乳腺癌的患者应结合钼靶与B超进行检查,二者联合检查可提高I期乳腺癌的早期诊断率。

Objective： To improve the early diagnosis of breast cancer through a study of the mammography and ultrasonography finding of the stage Ⅰ breast cancer. Methods： The mammography and ultrasonography findings of 146 cases of the stage Ⅰ breast cancer （φ≤2.0 cm） were studied and compared with pathological results. Results： The diagnostic accuracy of ultrasonography and mammography was no statistical difference respectively （P 〉0.05）. When 40 cases intramamary diameter were in 1 cm. When assessing the lession arising in atrophy type breast. However, In detecting breast fine cluster of calcification, the sensitivity of mammography was better than that of ultrasonography. There was a statistical difference between both modalities （P 〈0.05）, ultrasonography was surperior to mammography between 1 cm to 2 cm. Conelusions： The patient suspected of small breast cancer should combined the mammography with ultrasonography to improve the diagnostic rate of the stage Ⅰ breast cancer.
