Biography

Prof. Dr. Geke Hospers, MD PhD, is a medical oncologist at the department of Medical Oncology of the UMCG. She studied biochemistry and medicine. She obtained her PhD degree in 1989, with the thesis ‘Mechanisms and circumvention of cellular resistance to cisplatin’ at the department of Medical Oncology of the UMCG. During her Dutch Cancer Foundation (KWF) fellowship she worked on gene therapy topics in several labs in the Netherlands, the UK and Belgium and was trained as a medical oncologist. She co-supervised 11 PhD students, and is intensively involved in teaching medical students during their MSc. Furthermore, she coordinates national and international clinical studies, in collaboration with many multidisciplinary research groups within the UMCG and nationwide. In 2011 she was appointed as professor at the Department of Medical Oncology. Her current research is (among others) funded by the KWF. It focuses at sensitizing resistant tumors for drug therapy, genome based therapies and developing innovative imaging techniques to visualize drug targets.

Research focus

Exploring innovative imaging techniques to visualize drug targets.

In the UMCG, at the departments of Medical Oncology, Pathology, Nuclear Medicine and Pharmacy, extensive experience exists with regard to development and clinical use of various agents for molecular imaging. Molecular imaging is defined as the visualization, characterization and measurement of biological processes at the molecular and cellular levels in humans and other living systems. Agents used for molecular imaging can be anti-bodies or other targeted drugs, radiolabeled with a radioactive isotope that allows whole body visualization with the positron emission tomography (PET) technique. In cancer, molecular imaging can be used to detect several relevant targets in vivo, such as human Vascular Endothelial Growth Factor (VEGF) in the tumor environment and the Estrogen Receptor (ER). These novel imaging techniques are suitable for answering clinically relevant questions, such as presence and location of tumor lesions, whether or not a particular target for treatment is preserved during the course of the disease, and drug dosing. With 111In-bevacizumab we could visualize lymph node metastasis in stage III/IV melanoma patients. Future imaging studies in melanoma concentrate on BRAF and immune activation. In hormone positive tumors the Estrogen Receptor is an important target. The radiolabeled estrogen derivate 16beta-[18F]fluoroestradiol (FES), the ER expression can be visualized with PET. Different studies are performed to determine the clinical value of FES-PET.
