About

Von Hippel Lindau disease (VHLD) is an inherited syndrome characterized by vascular malformations, kidney cancer, adrenal gland and pancreas tumors. The VHL protein is not functional in the different disease associated lesions which results in production of high amounts of vascular endothelial growth factor (VEGF). Currently there are no clinical, radiographic or molecular markers that can predict the natural history of a given lesion. With 89Zr-bevacizumab positron emission tomography (PET) scanning, VEGF can be visualized and quantified.

The investigators hypothesize that 89Zr-bevacizumab PET imaging is a useful tool to predict the behaviour of disease associated lesions in patients with VHLD.

Adult patients with VHLD who have had routine magnetic resonance imaging (MRI) scans of central nervous system (CNS) and abdomen will undergo a 89Zr-bevacizumab PET scan. MRI will be repeated within 12 months.

Inclusion criteria

• clinically or genetically proven VHLD
• at least 1 measurable, VHL associated lesion in the CNS

• age ≥ 18 years
• written informed consent must be given according to good clinical practice (GCP), and local regulations

Exclusion criteria

• pregnancy
• any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol, those conditions should be discussed with the patient before registration in the trial
