Abstract
Objective

To analyze the role of core needle biopsy of axillary lymph nodes with suspected metastases from breast cancer and to correlate the imaging and histologic findings.

Material and methods

We retrospectively studied 74 patients diagnosed with breast cancer who underwent ultrasound-guided core needle biopsy of axillary lymph nodes with characteristics suggestive of metastases on ultrasonography. The following ultrasonographic findings were considered suspicious for metastases: cortical thickening and changes in the hilar fat and/or non-hilar cortical vascular flow. Patients with negative findings after axillary biopsy underwent sentinel node biopsy.

Results

Core needle biopsy confirmed lymph node metastases in 47 (63.5%) patients. The 27 patients (36.5%) with negative findings after lymph node biopsy underwent sentinel node biopsy; 3 (11%) of these had a positive sentinel lymph node and underwent axillary lymph node resection. Of the 50 lymph nodes with metastases, 44 (88%) had cortical thickening, 20 (40%) had changes in the hilar fat, and 29 (58%) had non-hilar cortical vascular flow. All biopsies of lymph nodes with both cortical thickening and non-hilar cortical vascular flow were positive, yielding a 100% positive predictive value in this series.

Conclusions

Ultrasound-guided core needle biopsy of axillary lymph nodes that are suspicious for metastases from breast cancer at ultrasonography is a highly effective procedure that has low morbidity. Findings of cortical thickening and non-hilar cortical vascular flow in the same lymph node yield a positive predictive value of 100% in this series.

Resumen
Objetivo

Analizar el papel de la biopsia con aguja gruesa de adenopatías axilares con sospecha ecográfica de metástasis en pacientes con cáncer de mama, y la correlación radiopatológica.

Material y métodos

Estudio retrospectivo de 74 pacientes diagnosticadas de cáncer de mama, a las que se realizó biopsia con aguja gruesa ecoguiada de adenopatías axilares con características ecográficas indicativas de metástasis. Consideramos hallazgos ecográficos sospechosos de metástasis: engrosamiento cortical, alteración de la grasa hiliar y/o flujo vascular cortical no hiliar. Las pacientes con biopsia axilar negativa se incluyeron en el protocolo de biopsia de ganglio centinela.

Resultados

La biopsia con aguja gruesa confirmó metástasis ganglionar en 47 (63,5%) pacientes. Las 27 pacientes (36,5%) con biopsia negativa se incluyeron en el protocolo de biopsia de ganglio centinela y 3 (11%) presentaron ganglio centinela positivo, realizándose linfadenectomía axilar. De las 50 adenopatías con metástasis, 44 (88%) presentaron engrosamiento cortical, 20 (40%) alteración de la grasa hiliar y 29 (58%) flujo vascular cortical no hiliar. En todas las adenopatías con engrosamiento cortical y flujo vascular cortical no hiliar la biopsia fue positiva, indicando un valor predictivo positivo del 100% en esta serie.

Conclusiones

La biopsia con aguja gruesa ecoguiada de adenopatías axilares con sospecha ecográfica de metástasis por cáncer de mama es un procedimiento con alta efectividad diagnóstica y baja morbilidad. La presencia de engrosamiento cortical y flujo vascular cortical no hiliar en la misma adenopatía mostró un valor predictivo positivo del 100% en esta serie.
