Utilization of preoperative ultrasound-guided fine needle aspiration cytology for the evaluation of axillary lymph nodes status in patients with early stage breast cancer / 中华内分泌外科杂志

ABSTRACT

Objective To study the utilization of preoperative ultrasound-guided fine needle aspiration cytology (FNAC) for the evaluation of axillary lymph nodes metastasis in patients with early stage breast cancer.Methods All 58 early stage breast cancer patients (cT1-2N0M0) whose ultrasound examination showed suspicious signs in axillary lymph node underwent ultrasound-guided fine needle aspiration.The cytopathological results were compared with the histopathological results.The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of ultrasound-guided fine needle aspiration for the axillary lymph node metastasis were analyzed.Results The sensitivity of ultrasound-guided fine needle aspiration was 84.1％,specificity 100.0％,positive predictive value 100.0％,negative predictive value 66.7％ and the diagnostic accuracy of ultrasound guided fine needle aspiration was 87.9％.Conclusions Preoperative axillary ultrasound-guided fine needle is a useful step in the process of axillary staging.The results provids valuable preferences for the option of axillary procedure in breast cancer
