Our third workshop on “Liquid Biopsy – CTC, DTC and more” at the Universitätsklinikum Hamburg-Eppendorf focused on diagnostic concepts of Liquid Biopsy in cancer research and provided hands-on training to familiarize the participants with major principles of detection and characterization of circulating tumor cells. The course offerd the opportunity to exchange learning and laid the foundation for further cooperation. The workshop participant Wadim Kisel adds: „It was a wonderful event. Many thanks for the impressions and suggestions of the exciting world of CTCs, which I was able to take home.”  Thanks Stefan Werner and Harriet Wikman for the great organisation and excellent talks!
