The 4th International Cancer Symposium
was held on 2-4 October 2019
, at the Palais des Congrès de Lyon. The aim of this edition was to address fundamental issues in cancer biology and to question how tumour cell plasticity contributes to enhanced tumour heterogeneity, sustained metastatic dissemination and escape from conventional and targeted therapies. Furthermore, this extended edition held alongside the “Gilles Thomas” Symposium, to commemorate this exceptional researcher, who had embraced the Lyon culture from 2009 to 2014. Gilles Thomas, who was Head of a CRCL Department, created the bioinformatics platform of the “Synergie Lyon Cancer Foundation”. His contributions to the field of Cancer Genetics were acknowledged worldwide.
