AACR 2019 — Congrès de l’association américaine de recherche contre le cancer

In this special issue of Oncology, we have summarized the most relevant topics that were presented at the American Association for Cancer Research (AACR) meeting. Our purpose here is to give the readers a concise report of the presentations that warrant particular attention. This year 2019 in Atlanta, the AACR Annual Meeting program covered the latest discoveries across the spectrum of cancer research - from population science and prevention; to cancer biology, translational, and clinical studies; to survivorship and advocacy - and highlights the work of the best minds in research and medicine from institutions all over the world. It was a five-day multidisciplinary program covering all aspects of cancer science from basic to translational as well as to clinical research. As a result of the great improvement of our knowledge on the molecular basis of cancer, many new-targeted therapies have been recently emerged. Our understanding on how tumors evade the immune system attack is a good example of this approach leading to the design of novel therapies. Given the increasing importance of cancer immunotherapy, we discuss herein the most recent achievements accomplished by this field. Finally, other approaches such as the study of the microbiome, epigenetics, and artificial intelligence as a tool in cancer research were also discussed at the AACR 2019 conference.
