The term neuroendocrine tumors, is used to describe tumors arising from hormone-producing cells. Such cells are located in most of the body's organs. Neuroendocrine tumors are rare, with a about 600 new cases per year in Norway, the majority located in the intestines or pancreas.

Neuroendocrine tumors usually grow slowly and life prospects of those affected are usually better than for most other cancers. The treatment differs somewhat from the treatment of other cancers partly because of the use of biological drugs (somatostatin, mTOR- and tyrosine kinase inhibitors) in addition to surgery, chemotherapy and radiation.

The group has a varied research activity, tightly related to the clinical work at the Regional senter for neuroendocrine tumors at Rikshospitalet and have both national and international collaborators.

The research activity spans from genetic analysis, to understanding of risk factors, clinical trials testing new treatment, studies evaluating existing therapy as well as Quality of Life end epidemiological studies.
