In an era of deep understanding of the molecular biology underlying the development of cancer, it is crucial that researchers and clinicians exchange knowledge. The ESMO 2017 Congress, in partnership with the European Association for Cancer Research (EACR), will bring cancer researchers and clinicians together to enable collaboration and the exchange of ideas, from the laboratory to the bedside and back. This exciting partnership creates a unique cancer congress in Europe with huge scientific reach and the true potential to improve the lives of cancer patients. The ESMO Congress is the most influential annual meeting for oncology professionals in Europe.
