title: Contrast-enhanced ultrasound: a filter role in AJCC stage I/II melanoma patients.
abstract: One of the most significant advances in melanoma staging is sentinel lymph node biopsy (SLNB). It is a surgical technique to detect occult nonpalpable micrometastases in regional lymph nodes. Recently, contrast-enhanced ultrasound (CEUS) was introduced as a noninvasive procedure, in spite of SLNB, for the detection of SLNs in patients with cutaneous melanoma. The main purpose of this study was to evaluate the diagnostic accuracy of CEUS in the diagnostic workup of patients with melanoma in comparison with the final histology of SLNs detected through preoperative lymphoscintigraphy. Fifteen patients with cutaneous melanoma underwent prompt excisional biopsy with narrow margins in order to avoid impairment of the melanoma lymphatic basin and were referred for SLNB according to routine indications between January and February 2009. In our study CEUS showed, albeit based on a small patient sample, a negative predictive value of 100%, that means that all negative results were confirmed by negative SLN histopathological examination; all ultrasonographically negative lymph nodes corresponded to nonmetastatic sentinel nodes.
