The positive predictive value of axillary sonography was 54%. The sensitivity and specificity of fine\u2010needle aspiration biopsy were 73% and 100%, respectively, and those of core\u2010needle biopsy were 77% and 100%. Results did not differ significantly between sonographically guided core\u2010needle biopsy and fine\u2010needle aspiration biopsy. The complication rates of fine\u2010needle aspiration biopsy and core\u2010needle biopsy were both 4%, and fine\u2010needle aspiration biopsy and core\u2010needle biopsy cost $180 and $350, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Both sonographically guided fine\u2010needle aspiration biopsy and core\u2010needle biopsy were useful for axillary staging of breast cancer with high sensitivity.
