目的比较钼靶、超声双重联合引导麦默通(MMT)微创旋切术与传统粗针活检术在乳腺BI-RADS 4A类“微钙化非肿块型”病灶诊治中的优劣,探讨其应用价值。方法回顾性对比分析106个病灶MMT及粗针穿刺活检术的病理结果及漏诊率、低估率。结果 106个病灶中癌前病变及原位癌(共32个,30.19%)较为常见。MMT对乳腺癌前病变及原位癌检出率高于粗针穿刺活检术(P<0.05);MMT对病灶漏诊率和癌前病变及原位癌的病情低估率皆低于粗针穿刺术(P<0.05)。结论双重联合引导MMT微创旋切术对乳腺BI-RADS 4A类“微钙化非肿块型”病灶诊断效能优于粗针穿刺活检,能有效发现乳腺早期恶性病变;能微创、安全地切除该类型病灶。
Objective To compare the advantages and disadvantages of mammography and ultrasound combined with MMT and traditional needle biopsy in the diagnosis and treatment of breast type BI-RADS 4A non-tumor type microneedles Its application value. Methods Retrospective analysis of 106 lesions MMT and thick needle biopsy pathology results and missed diagnosis rate, underestimate the rate. Results Of the 106 lesions, precancerous lesions and carcinoma in situ (32, 30.19%) were more common. The detection rate of MMT in premalignant breast lesions and carcinoma in situ was higher than that of the thick needle biopsy (P <0.05). The underestimation rates of MMT in misdiagnosis rate, precancerous lesions and carcinoma in situ were lower than those of MM (P <0.05). Conclusions The dual combined guided MMT minimally invasive polypectomy is superior to the needle biopsy in the diagnosis of breast BI-RADS type 4A “microcalcification non-tumor type” lesions, which can effectively detect malignant lesions in the early stage of breast. Excision of this type of lesion.
