ABSTRACT
AIMS:
The purpose of this study was to analyze the diagnostic yield and accuracy of the ultrasound (US) guided core biopsy in a population of patients with osteolytic metastasis. MATERIALS ANDMETHODS:
We performed a retrospective analysis of 16 consecutive cases of US-guided core biopsies of osteolytic lesions performed in our Ultrasound Unit, from January 2006 to May 2017. We used 18G or 16G Tru-cut needles coupled with automated biopsy guns. We procured a maximum number of two tissue specimens per patient.RESULTS:
We obtained a diagnostic yield and accuracy of 93.75% (15 of 16 patients) for US-guided core biopsy of osteolytic metastasis. Most of our cases were metastasis of adenocarcinomas (8 patients), squamous cell carcinomas (3 patients) followed by multiple myelomas (2 patients). Other pathologic lesions recorded were undifferentiated carcinoma (1 patient) and mesenchimal undifferentiated tumor (1 patient). The pathologic result was inconclusive in one patient.CONCLUSIONS:
Our study supports the important diagnostic role of US-guided core biopsy for osteolytic bone metastasis. Two US-guided passages may be sufficient to procure a diagnostic tissue samples from osteolytic bone metastasis, if theirlength is at least 10 mm.
