麦默通微创活检及针吸细胞学对乳腺癌诊断价值的比较

The Comparison between Mammotome Minimally Invasive Biopsy and Fine Needle Aspiration Cytology on Breast Cancer

目的比较麦默通微创活检及针吸细胞学对乳腺癌诊断的应用价值。方法对64例乳腺癌患者术前行超声引导下MMIBS及FNAC,并对两种方法的诊断价值进行评价。结果64例患者超声显示率为100%。MMIBS阳性率为96.8%,FNAC为76.5%(P>0.05);MMIBS假阴性率为4.2%,FNAC为23.4%(15/64)(P<0.05);两种诊断方法假阳性率为0。结论FNAC简便、安全、创伤小,但有阳性率较低、漏诊率较高之不足;MMIBS具有高确诊率、低漏诊率、微创之特点,可作为乳腺肿块定性的首选。

Objective To explore the clinical value between mammotome minimally invasive biopsy（MMIBS） and fine needle aspiration cytology（FNAC）on breast cancer. Methods 64 cases of breast cancer were performed by ultrasound guided MMIBS and FNAC. The two methods of diagnosis in breast cancer were evaluated. Results The needle position in 64 patients was all visualized （100%） by ultrasound guided. Among them,the positive rate of MMIBS was 96.8% and FNAC 76.5%（P〉 0.05）. The pseudonegative rate of MMIBS was 4.2% and FNAC 23.4% （P 〈 0.05）. The pseudopositive rate of the both methods was zero. Conclusion FNAC was convenient, safe,micro-invasive,but has lower positive rate and higher pseudonegative rate. MMIBS was in the character of micro-invision, high definitive and low pseudonegative rate. MMIBS was recommended as the first choice of definitive diagnosis for breast cancer.
