Summary

Tumour angiogenesis has been identified to play a critical role in tumour growth and this knowledge has led to the identification of new targets for cancer therapy. Multiple angiogenic factors are involved in the regulation of angiogenesis, among them VEGF (vascular endothelial growth factor) and its receptor are of crucial relevance. The inhibition of VEGF signaling by monoclonal antibodies or small molecules (kinase inhibitors) has already been successfully established for the treatment of different cancer entities and multiple new drugs are being tested in clinical trials. The ever-expanding list of antiangiogenic agents being available in the near future will raise the questions when to use which agent and in which sequence. As a consequence biomarkers are going to be indispensible tools for choosing the most effective drugs and to predict dosing and resistance. The present project is based on an academic clinical trial in which patients suffering from different cancer types (colorectal cancer, non-small cell lung cancer, renal cell cancer and hepatocellular cancer) treated routinely with antiangiogenic agents will be included. Consecutive serum and blood probes will be taken and will be examined and correlated with functional imaging and the clinical course. The following parameters have been selected: soluble markers in the plasma (VEGF, bFGF, ICAM, sVGFR-2 IL-8, SDF1 and Dickkopf 3) and cellular parameters like circulating endothelial cells (CEC) and circulating endothelial progenitor cells (CEPs). In conclusion, the present project is screening for potential biomarkers and biomarker combinations relevant for antiangiogenic drugs in different tumour types. The predictive value of such profiles should then be evaluated in larger cohorts. In the future such profiles could possibly help clinicians to use these agents more effectively and therefore also more economically.
