Margaret Foti, Chief Executive Officer of AACR and Prof. Fabien Calvo, Scientific Director of INCa for their friendship, trust and genuine collaboration. Previous tumor microenvironment conferences enjoyed great success both with respect to scientific standards as well with respect to the social events. I have many reasons to believe that the Versailles conference will surpass the previous ones in all aspects. I am proud to announce that the number of registrants and presenters in the Versailles conference has reached an unprecedented mTOR inhibitor high. I greatly appreciate the creativity and hard work
of my colleagues on the program committee. Special gratitude is offered to our sponsors; their support has been essential. I thank Smadar Fisher and her colleagues at the Scientific Secretariat for the superb coordination of the scientific and selleck screening library social events. The magnificent Châteaux de Versailles, the official residence of the Kings of France from 1682 until 1790, and its stylized English and French gardens, await your visit. The palace and its gardens are the perfect ambience in which to reflect upon the novel and enriching insights gained from the presentations of our colleagues. I wish all of us an exciting, stimulating and enjoyable conference. Isaac P. Witz Conference Chair”
“The tumor microenvironment (TME) is a
pivotal factor in tumorigenesis and especially in tumor progression and the pathogenesis of cancer is largely dependent on its interactions with microenvironmental components. This paradigm should be clear to every cancer researcher, as it is for the participants of the “5th International Conference on Tumor Microenvironment: Progression, Therapy & Prevention”. This presentation
attempts to highlight certain key events of the developmental phase of the “tumor microenvironment” concept which lead to the contemporary achievements of this research area. The essay which is not intended to serve as a comprehensive review will conclude with a biased view as to challenges facing TME researchers. Stephen Paget laid the foundations of the TME research triclocarban area by formulating the seed and soil theory. Paget’s concept lay dormant for many years. Only in the mid seventies of the 20th century and onwards did a relatively small group of people revisit Paget’s ideas [1–9]. Auerbach [10], for example, cites Paget: “The best work in the pathology of cancer is done by those studying the nature of the seed. They are like scientific botanists; and he who turns over the records of cases of cancer is only a ploughman, but his observations of the properties of the soil may also be useful”. Auerbach then expresses his own views on cancer researchers who study the tumor microenvironment: “Those individuals who study the properties of the host environment should not be ignored.
