钼靶X线定位穿刺留置导丝活检对乳腺微小病灶的诊断价值

目的探讨乳腺X线定位穿刺留置导丝活检术对乳腺微小病灶的诊断价值。方法回顾分析临床触诊阴性而乳腺钼靶X线片显示的微小病灶28例,采用乳腺钼靶X线定位下穿刺,留置导丝于微小病灶区,引导手术将病灶切除活检。结果28例微小病灶均一次性定位成功,定位满意率93%,手术切除完整。病理检查:恶性病变9例,其中浸润性导管癌5例,导管内癌伴早期浸润1例,导管内癌2例,髓样癌1例;良性病变19例。结论乳腺钼靶X线定位穿刺留置导丝活检术,定位准确,诊断明确,能确定乳腺微小病灶的性质,是目前诊断早期乳腺癌的有效方法。

Value of Molybdenum Target X-ray Stereotactic Localized Biopsy with Resident Metal Wire in Breast Minute Lesions

Objective To evaluate X-ray stereotactic localized biopsy with resident metal wire in the diagnosis of breast minutelesions. Methods 28 cases of breast minute lesions were analyzed retrospectively,all cases were non-palpable clinically,but were positive by mammography.Needle biopsies were executed under X-ray stereotactic localization,and a thin metal wire was sited in lesion to instruct resection. Results All of 28 cases with minute lesion were successfully localized and completely resected,localization satisfaction rate was 93% percent.Pathological diagnosis showed benign lesion in 19 cases,and malignant lesion in 9 cases.Among the 9 malignant cases,there were 5 cases of invasive duct carcinoma,1 case of duct carcinoma with early invasion,2 cases of duct carcinoma,and 1 case of medullary carcinoma. Conclusion X-ray stereotactic localized biopsy with resident metal wire can provide accurate localization and precise diagnosis,especially in the diagnosis of occult breast cancer.It is an efficient method in the diagnosis of early breast carcinoma.
