Many cancer patients are difficult to cure, especially when having metastatic disease. Systemic therapy with radiopharmaceuticals could then be beneficial, due to the possibility to reach all tumour cells spread in the body. New knowledge regarding tumour biology, pathology and molecular biology demonstrate more tumour specific features/biomarkers that can be used for development of more specific radiopharmaceuticals and treatment strategies.
Our overall aim is 1) to study the possibilities to develop, optimise and apply new radiopharmaceuticals for therapy, and to optimise current treatment protocols, and to 2) enhance the understanding of mechanisms behind effects of ionising radiation both on tumour and normal tissues in vivo.
Some of the specific aims are:
- to optimise treatment with radiolabelled hormone analogues for hormone receptor-expressing tumours.
- to define possible biomarkers for radiotoxicity in tumour and normal tissues.
- to optimise radionuclide therapy using enhanced understanding of basal molecular mechanisms behind radiobiological effects on tumour tissue and critical normal tissues.
- to enhance the knowledge on radiation dosimetry and tolerance doses for radionuclide therapy in critical normal tissues.
- to develop multi-parametric MRI for non-invasive evaluation of tumour tissue characteristics after radionuclide therapy.
Much research is focussed on the radiolabelled somatostatin analogue 177Lu-octreotate and the norepinephrine analogue 131I-MIBG for therapy of neuroendocrine tumours.
Currently, we examine ways to increase the radiobiological effects on tumour tissue by optimal fractionation schedules, new administration routes, increasing the receptor expression, reducing receptor saturation, combination with other agents (radiosenstizing).
We also examine ways to reduce the side effects on critical normal tissues, e.g by reducing kidney uptake and kidney toxicity. Furthermore, we suggest and validate biomarkers for radiobiological effects (toxicity) on tumour and normal tissues.
We perform translational studies on cell culture, mice, rats and patients. Pharmacokinetic and dosimetric studies are performed in tumour-bearing animals and man. Studies on toxicity and biological effects utilizes e.g imaging techniques (scintigraphy, MRI), histopathology, PCR and blotting techniques, microarray techniques, sequensing techniques, epigenetic analyses.
