ten years ago the European Research Consortium EuroFlow embarked upon the development of novel, fully standardized flow cytometric approaches for making the diagnostic decisions in hematological malignancies and monitoring follow-up samples. The recent EuroFlow development of next-generation flow cytometry nicely illustrates the power of generating congruent (standardized) data sets which open up new possibilities in data analysis. The concept of basing the immunophenotypic classification of hematological neoplasias on developmental pathways was successfully extended to Immunology and the diagnosis of immune deficiencies as well as immune monitoring. In addition, the immediate need of a diagnostic flow lab for sensitive MRD testing has been addressed for several diseases.The achievements of the consortium to date will be summarized at the EuroFlow Educational Symposium and Workshop scheduled March 17-18, 2017 in Kiel. It will be focused on the application of newly developed tools for the precise diagnosis and monitoring follow-up samples of hematological malignancies. Moreover, we will present ongoing EuroFlow activities in immune system profiling and provide you with the opportunity to address the experts with your questions. Case presentations will allow all participants to gain hands-on experience with novel data analysis software, thus giving ample opportunity to discuss practical details with EuroFlow members. Interested participants can also join two hands-on workshops at the Kiel Hematology Lab in connection to the symposium. We are looking forward to an exciting meeting and we cordially invite you to participate.
