目的
2
探讨早期乳腺癌原发灶切除术后经皮与经静脉超声造影(P-Ⅳ-CEUS)的联合使用在前哨淋巴结中的应用价值。
方法
2
回顾性分析42例外院早期乳腺癌原发灶切除术后患者的临床-影像资料,所有患者均在我院进行再次手术。术前行前哨淋巴结P-Ⅳ-CEUS检查,术中采用亚甲蓝示踪剂进行前哨淋巴结切除活检,分析超声造影和前哨淋巴结活检的检出率和假阴性率,以手术病理结果为金标准,探讨超声造影对前哨淋巴结的诊断效能。
结果
2
前哨淋巴结经皮超声造影(P-CEUS)的检出率和假阴性率分别为92.9%(39/42)和7.1%(3/42),亚甲蓝染色的检出率为100%(41/41),1例因穿刺证实为转移性进行新辅助治疗;P-Ⅳ-CEUS的敏感性、特异性、阳性预测值、阴性预测值、准确率分别为66.7%(2/3)、100%(37/37)、100%(2/2)、97.3%(36/37)、97.4%(38/39)。
结论
2
早期乳腺癌原发灶切除术后P-Ⅳ-CEUS的联合使用可精准检出前哨淋巴结并准确判断其性质,为术前减少有创前哨淋巴结活检提供可靠依据。
Objective
2
To investigate the value of percutaneous and intravenous contrast-enhanced ultrasound(P-Ⅳ-CEUS) in sentinel lymph nodes(SLNs) after resection of early-stage primary breast cancer.
Methods
2
A retrospective analysis was done on the clinical and imaging data of 42 early breast cancer patients. Following primary tumor resection, all these patients underwent reoperation in our hospital. SLNs were examined by preoperative P-Ⅳ-CEUS and intraoperative sentinel lymph node biopsy(SLNB) was performed by using Methylene blue as a tracer. Then we analyzed the detection and false-negative rate in CEUS and SLNB respectively. By using the surgical pathological results as the gold standard, the diagnostic efficacy of CEUS for SLNs was explored.
Results
2
The detection rate and false negative rate of SLNs in percutaneous contrast-enhanced ultrasound (P-CEUS) were 92.9% (39/42) and 7.1% (3/42), respectively. The detection rate in methylene blue staining was 100% (41/41) and one patient underwent neoadjuvant therapy due to biopsy-confirmed metastasis. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of P-Ⅳ-CEUS were 66.7% (2/3), 100% (37/37), 100% (2/2), 97.3% (36/37) and 97.4% (38/39), respectively.
Conclusions
2
P-Ⅳ-CEUS after resection of early-stage primary breast cancer can accurately detect SLNs and characterize their status, which is a reliable clinical basis for reducing invasive SLNB.
