ABSTRACT
ObjectiveTo 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. MethodsA 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. ResultsThe 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. ConclusionsP-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.
