In the western world, cancer is the second leading cause of death after cardiovascular diseases. According to the WHO, 15 million people will be newly diagnosed with cancer by 2020. This would imply an increase in the incidence rate by 50% compared to the year 2000. The diagnosis and especially the accurate staging of the tumor expansion play a decisive role for prognosis and therefore therapy decision. The understanding of the various mechanisms of cancer grows steadily. It is known that there are differences in the metabolism and growth regulation between cancerous cells and normal cells. This can be diagnostically used for a targeted detection of tumors. To date, the most established tracer in the field of PET for staging of malignant tumors, e.g. lung cancer, is a sugar tagged with radioactive fluorine, the so called F18-desoxy glucose, abbreviated FDG. This sugar is particularly taken up by fast growing cells and used in metabolic processes. It allows the detection of tumor cells but also other proliferating and metabolically active cells of the tissue via PET imaging. However, the differentiation between malignant tumor cells and other (benign) alterations of the tissue is limited. Tracer molecules which mainly target tumor cells could allow a more specific diagnosis and more precise staging of cancer in the future. Molecular imaging at Bayer Schering Pharma
Molecular imaging comprises diagnostic procedures that in particular allow the detection of early disease stages on a cellular and molecular level, potentially even before they become clinically manifest. Such procedures are expected to provide not only earlier but also more accurate detection of, for example, tumors and central nervous system disorders. In the field of molecular imaging, Bayer Schering Pharma is pursuing promising approaches with innovative carrier molecules that bind specifically to certain cell structures. This will facilitate the development of procedures for visualizing disease-specific biological processes on a molecular level. The diagnosis of neurodegenerative, oncological and cardiovascular diseases is the company's main focus of research. Bayer Schering Pharma maintains various research cooperations in the field of molecular imaging, amongst others with Stanford University as well as ETH Zurich and Nagasaki University.
