Study Description

Brief Summary: The distribution of stable (non-radioactive) isotopes in living organisms is increasingly studied, in particular the zinc (Zn), copper (Cu) and iron (Fe), not only in primitive organisms, but also in mammals. The scientific community shows a growing interest in the study of the isotopic distribution of Cu in humans: this distribution can vary according to gender or nutrition. Concerning pathology, the isotopic distribution of Cu seems interesting in Wilson's disease or in cirrhosis. Additionally, a promising area of study focuses on the role of Cu in cancerous tumors, neoangiogenesis, the mechanisms of free radicals reduction and signaling pathways. Head and neck cancers are sensitive to platinum salts. Links between platinum and Cu are important: platinum penetrates into the cell through a Cu receptor, it interacts with the regulation mechanisms of Cu and platinum. Preliminary studies suggest a variation of the measurable isotopic distribution of Zn in patients with breast tumor and of Cu in patients presenting breast as well as colorectal tumors. The Larner et al. study suggest a promising role of Zn in breast cancer, indeed, results highlight a variation of distribution of Zn in 10 breast tumors. Concerning the study of Télouk et al. on 8 patients presenting colorectal tumors and 20 patients presenting breast tumors, results are in favor of an increase of mortality when Cu 65 is decreased in the serum and the isotopic modifications happen earlier than usual modifications of biochemical tumor markers such as: carbohydrate antigen (CA) 19.9, Carcinoma Antigen (CA) 15.3, Carcinoembryonic antigen (CEA). Currently, there is no information about the distribution of the stable isotopes of Cu in head and neck tumors. The objective of the study is to determine if the distribution of 65Cu / 63Cu is modified in tumoral tissues compared to healthy tissues. The isotopic distribution of the Cu in 2 tumor types, head and neck tumors and lymphomas, will be also investigated in order to determine if this distribution is specific of a tumor type or not. In case of positivity of this variation, the prognostic interest of these parameters will be evaluated.
