Sažetak
Background: Melanoma can early metastasize to regional lymph nodes. The sentinel lymph node (SLN) is the first lymph node draining directly from the site of primary melanoma, and the pathohistological status of the SLN is the most significant prognostic factor for overall survival prevalence and prognosis in patients with melanoma. Ultrasound is a very useful for the imaging of regional lymph node metastases, combined with Doppler and cytopuncture. Objective: The aim of this study was to investigate the role of ultrasound assessment of regional lymph nodes in melanoma staging. Patients and methods: The study included all patients with primary melanoma detected in the period between 2003 and 2012, in whom diagnostic processing has not proven distant metastases or physical examination did not find enlarged lymph nodes. In total, 202 surgically treated patients were included in the study, of which 101 patients underwent ultrasound examination of regional lymph nodes using a linear probe of at least 12 MHz, while ultrasound of regional lymph nodes was not performed for 101 patients. Results: The results of this study emphasize the importance of ultrasound in the diagnostics and treatment of patients with melanoma. Based on the observation of the occasional positive ultrasound and fine needle aspiration cytology (FNAC) in regional lymph nodes, our results indicate that a proportion of patients can avoid sentinel lymph node biopsy (SLNB). In case of a positive ultrasound findings (complemented with FNAC of suspicious nodes), direct dissection of regional lymph nodes is recommended. However, negative ultrasound findings do not exclude the presence of micrometastases due to poor sensitivity of this method and is not a contraindication for SLNB. Conclusion: Therefore, there is a need for further studies on metastatic melanoma, especially those in the sentinel lymph nodes and in its early stage.
