Updated publication reference for PubMed record(s): 30975894. Liquid biopsies are becoming imperative on early patient diagnosis, prognosis and evaluation of residual disease. The use of circulating extracellular vesicles (EVs) as surrogate markers of tumor progression could be a powerful tool in the clinical setting. EVs in plasma have emerged as a non-invasive option to detect metastatic outcome, however sensitivity is low. Here we have characterized the lymph obtained after postoperative lymphadenectomy as a novel biological fluid enriched in EVs. Our proteomic profiling and BRAFV600E/K status determination demonstrate for the first time that EVs from the lymph of melanoma patients are enriched in melanoma-associated proteins and are useful for BRAF mutations detection. Melanoma oncogenic pathways, immunomodulation and platelet activating proteins are enriched in lymph-derived exosomes from patients with distal lymph node spread compared to local/early spreading. Furthermore, patients positive for BRAFV600E mutation on lymph-circulating vesicles had a shorter time of relapse. These data encourage the analysis of lymph-circulating EVs for detection of residual disease and recurrence.ADDENDUM: After the proper verification of the cell lines analysed in this dataset where it is written "SKMel103" or "SK103", it should be read as "SKMel147". This affects not only the raw files but also all the search results files. Sorry for the inconveniences.
