乳腺动态电阻抗扫描仪对早期乳腺癌检测敏感度的初步分析研究

Preliminary Analysis of Sensitivity of the Electrical Impedance Scanning Instrument for Early Breast Cancer Detection

目的：评价乳腺动态EIS技术对早期乳腺癌的检测敏感度,分析其临床技术优势。方法：对入组的67例对象进行乳腺动态EIS检测,分析不同临床体征（大小、位置、硬度）乳腺病变对检测敏感度的影响。结果：动态EIS对病变直径〈1.0cm及1～2.0cm的检测敏感度为85.0%及87.2%,对位于乳头乳晕区、乳腺外、内侧象限病变的敏感度为75.0%、88.9%及87.5%,对囊、实性病变敏感度为83.3%和88.3%。结论：该技术具有对组织功能性变化敏感检测的优势,有望用于乳腺癌早期筛查。

Objective： to evaluate the sensitivity of the dynamic EIS technology for early breast cancer detection, furthermore to analyze its clinic technology advantages.Methods： 67 cases of breast cancer were detected by the dynamic EIS, and the inlfuences of different clinical characteristics lesions （size, position and hardness） on the detection sensitivity were analyzed.Results： For the diameters of the lesions were 〈1.0cm and 1-2.0cm, detection sensitivities of dynamic EIS were 85.0% and 87.2%. For the lesions located on the nipple areola, lateral and inside, the sensitivities was 75.0%, 88.9% and 87.5%. For the cystic and solid lesions, the sensitivities were 83.3% and 88.3% respectively.Conclusion： the dynamic EIS technique has the advantage of the sensitivity to the change of tissue function, and is expected to be used for early breast cancer screening.
