Clinico-biological Database in Patients Treated With Metabolic Radiotherapy in the Nuclear Medicine Department

Study Overview
=================
Brief Summary
-----------------
Development of a prospective clinico-biological database allowing the provision of clinical data and corresponding biological materials to the medical and scientific community.

Detailed Description
-----------------
Targeted radionuclide therapy (TRT) aims at delivering ionizing radiation specifically to tumors for therapeutic purposes. Different types of radionuclides can be used to deliver the radiation: beta emitters less (Iodine-131, Lutecium-177), alpha (Radium-223) or Auger (Indium-111). They will target tumor cells either by natural tropism (iodine for thyroid cancer, for example) or by coupling them to a vector (antibody, peptide ...). Patients with thyroid cancer, prostate cancer or neuroendocrine tumors who should benefit form TRT may be included in this project. The clinical-biological database will help better understanding of the radiobiological mechanisms of action of ionizing radiations on both normal tissues and tumor cells and the psycho-oncological mechanisms involved in patients treated with TRT (only for ICM's patients). The collected data will help treatment optimization. To meet these demands, the research must then integrate databases creation open to researchers and the ongoing evaluation of the impact of projects on the health of cancer patients. Integrated research associated with quality biological research is the guarantee of medical progress. The multidisciplinary structure around collections of biological resources will enable the various actors to harmonize not only the collection but also the sharing of their data with a view to making them available for medico-scientific projects at a regional and national dimension. The Clinical Biological Database (BCB) should be used to identify and characterize new molecular markers for better diagnosis and / or treatment. It should also permit to optimize the collection of all this information, their integration and their transversal exploitation by different research disciplines (epidemiological, fundamental, translational, clinical). An ancillary study IMMUNORIV is associated to BCB RIV : The specific research aim is, first, to determine whether immune cell (lymphocytes and macrophages) scoring and characterization in metastatic thyroid cancer and NET samples at diagnosis predict the response to TRT. Second, a high-throughput approach will be used to determine i) the immune cell profile in blood samples from patients with NET, before and after TRT initiation, and ii) its possible correlation with the response to TRT. Third, using imaging techniques the possible correlation will be evaluated between tumor uptake/absorbed dose and response to TRT. By monitoring the immune response during TRT, the IMMUNORIV project will allow to identify immune response-related biomarkers that may be modulated to improve TRT effect.
