Detection of axillary metastases in breast cancer patients using ultrasound and colour Doppler combined with fine needle aspiration cytology.
The aims of this study were to evaluate the diagnostic value of ultrasonography and colour Doppler combined with fine needle aspiration (FNA) cytology for the detection of non-palpable axillary lymph node metastases in breast cancer patients. Forty patients with operable breast cancer (T1/T2), invasive carcinoma, not submitted to neo-adjuvant therapy, underwent axillary ultrasonography and colour Doppler preoperatively. FNA cytology was performed on axillary lymph nodes presenting ultrasonographic and/or Doppler suspicious features. A total of 542 lymph nodes were surgically removed from the 40 patients; 19 were metastatic lymph nodes. Ultrasound-guided FNA detected metastases in six out of 11 histologically node-positive patients. Sensitivity and specificity in this preliminary study was 55% and 100%, respectively. These are the preliminary results of a prospective study that has the purpose of reducing the sentinel node procedures in breast cancer patients with clinically negative axillae, but positive FNA cytology.
