目的:探讨乳腺X线定位穿刺留置导丝活检技术对乳腺微小病灶的诊断价值。方法:回顾性分析临床触诊阴性而乳腺钼靶X线片显示的微小病灶36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:36例微小病灶均一次性定位成功,手术切除完整。病理检查:恶性病变11例,其中浸润性导管癌7例,导管内癌2例,导管内癌伴早期浸润1例,髓样癌1例;良性病变25例。结论:乳腺钼靶穿刺定位活检术定位准确,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。
Objective: To investigate the diagnostic value of mammography-guided wire biopsy in diagnosis of minimal breast lesions. Methods: Thirty-six cases of minimally invasive lesions of mammograms were retrospectively analyzed. Mammography was performed under the mammographic X-ray. The lesions were excised and biopsy guided by guidewire. Results: All the 36 cases of small lesions were successfully located at one time. The surgical resection was complete. Pathological examination: Malignant lesions in 11 cases, including invasive ductal carcinoma in 7 cases, ductal carcinoma in 2 cases, ductal carcinoma with early invasion in 1 case, medullary carcinoma in 1 case; benign lesions in 25 cases. Conclusion: Molybdenum target biopsy can accurately locate the breast lesion, and it is an effective method to diagnose early stage breast cancer.
