The most important prognostic factor for the patients with breast cancer are metastases to axillary lymph nodes (ALNs). Preoperative ultrasound (US) combined with fine needle aspiration biopsy (US-FNAB) has been proved to be the most reliable method to detect nonpalpable axillary metastases in patients with breast cancer. Our study was aimed to examine the value of US contrast agent (CA) SonoVue in the US examination of the axilla for the detection of axillary lymph node (ALN) metastases in breast cancer patients. Therefore, two studies were performed. The first study included 27/70 patients with breast cancer who had an indeterminate result of the standard US examination of the axilla (L/T < 1.2 or MCT > 3 mm or predominantly non-hilar vessel signal) and underwent US examination with CA. In the second study, 26 breast cancer patients underwent standard axillary US examination performed independently by two skilled operators. The patients with indeterminate or malignant ALN underwent US- guided fine needle aspiration biopsy (US-FNAB). For macrometastases, the sensitivity, specificity, NPV and PPV of US-FNAB were 91%, 93%, 100% and 100%, respectively. The reproducibility of the standard US examination (the second study) was 85% (22/26 patients), and for the metastases larger than 5 mm, it was 100%. Moreover, our second study proved that the same results as with CA can be achieved by two skilled operators performing a standard US examination. The sensitivity of both operators was 92%. In the case of metastases larger than 5 mm, the reproducibility was 100%. Micrometastases remain a problem also in the hands of very experienced operators even if using CA.
