Clinical Trial Summary

The primary objective of this study is to analyse the concentration dopamine and serotonin in thrombocytes of patients with renal cell carcinoma and neuro-endocrine tumours compared to the concentrations of these catecholamines in healthy volunteers. The concentration dopamine and serotonin in thrombocytes with and without medication will also be evaluated.


Description:

- To analyse the concentration catecholamines in thrombocytes of patients with clear cell renal cell carcinoma and low grade neuroendocrine tumours. - To compare these concentrations with the concentrations catecholamines in thrombocytes of healthy controls. - To analyse the concentration catecholamines in thrombocytes of patients with clear cell renal cell carcinoma and patients with low grade neuroendocrine tumours with and without medication.
