COMMUCAN

Intercellular COMMUnication in CANcer biology and Therapy

Presentation

The cancer treatments are either nonspecific (radiotherapy, chemotherapy) and destroy all the cellular components of the tumor whether they are protective or not, or “too” specific (targeting a particular cellular component in the tumor) which leads has resistance to treatment and relapse. Understanding the heterogeneity of tumors in order to characterize the communications between tumor cells, healthy stromal cells, vessels, immune cells and extracellular matrix is ​​necessary to propose a treatment with a suitable specificity. The objective of this program is to propose new treatments to increase the survival rate of patients by acting on the entire microenvironment and to exceed the limits of traditional treatments. To do this, COMMUCAN (Intercellular Communication in Cancer Biology and Therapy) studies the contribution of this communication to the failures of some of the current treatments and develops new therapeutic strategies based on 3D images of the tumor and not only on the targeting of metabolic pathways .

COMMUCAN should allow:

  • Identify new communication networks within the tumor microenvironment involved in tumor progression and metastasis;
  • Continue clinical and preclinical research for newly identified targets and biomarkers;
  • Develop new therapies based on a more comprehensive understanding of tumor biology and communications between different cell types;
  • Development of therapeutic and diagnostic nanotechnologies targeting elements of the tumor microenvironment;
  • Develop mathematical models and computational methods of disease modeling as well as predictive models of clinical outcomes focusing on tumor and tumor microenvironment interactions;
  • Apply the principles and conceptual analysis of evolutionary economics to better understand tumor progression.

Andreas Bikfalvi, Julie Déchanet-Merville and Alain Ravaud co-coordinate all the research of the COMMUCAN project within BRIO, in constant link with the manager program. They set up the main strategic axes of the clinical and preclinical research of the program, in accordance with the budgets, the competitive and medical environment. They co-lead the 2 annual program progress meetings as well as the preparation meetings of the Scientific Advisatory Board (SAB) (1 to 2 meetings / year).

Expertise: The Digestive Tumor Unit of the Institut Bergonié has a long experience in clinical research on colorectal cancer and more specifically on their metastases. The team was among the first to prospectively validate the concept of parenchymal protection approaches using intraoperative radiofrequency ablation. Particularly involved in clinical research methodology, the EORTC SURCARE platform was created to develop prospective (mainly phase 4) studies in collaboration with the European Society of Surgical Oncology. Two prospective studies are underway on colorectal liver metastases (CLIMB EORTC 1409, DREAM EORTC 1527) based on a European clinical network (more than 15 reference centers), extended in Japan with collaboration with JCOG and more recently with MD Anderson. The EORTC will set up a centralized biobank based on these studies and will feed several international translational research programs. In summary, the team is leading a large international clinical network in surgical oncology that offers significant prospective resources for translational studies.
