"Dear Friends and Colleagues,
It is our great pleasure to invite researchers from Academia and industry and clinicians from all over the world interested in the field of Liquid Biopsy to the 4th ACTC “Liquid Biopsy: Latest Advances and Future Challenges” meeting. After having organized three very successful ACTC meetings in Greece, we now organize the 4th ACTC meeting in the beautiful island of Corfu, Greece, on October 2–5, 2019 (www.actc2019.org), focusing on late breaking news on CTCs, ctDNA, circulating miRNAs and extracellular vesicles technologies and their clinical applications."
