The MPN&MPNr-EuroNET network was established in 2009 to bring together scientists and physicians active in the fields of myeloprolifeative neoplasms (MPN) and related hereditary diseases (MPNr: hereditary erythrocytosis and thrombocytosis) to discuss advances and challenges in the biology and treatment options for myeloid neoplasms. Since its establishment, the MPN&MPNr-EuroNET network has been active in organizing meetings and fostering collaborations within and outside the network. Following the success of the 16th MPN&MPNr-EuroNet meeting in Belgrade in 2023, the 17th MPN&MPNr-EuroNET conference will take place on 14-16th May 2025 in St. Gallen, Switzerland.
