Malignant Peripheral Nerve Sheath Tumors: Molecular biology and translational research

Background

Malignant peripheral nerve sheath tumors (MPNST) are rare soft tissue cancers that arise in neuroectodermal cells in the peripheral nervous system. About half of the patients carry the additional burden of Neurofibromatosis type 1 (NF1), which is a hereditary genetic disease that significantly increases risk of developing MPNST, as compared to the general population. Although MPNST is rare, there is a great need to improve the current treatment, as most patients are young adults and the survival prognosis is poor. The current treatment of MPNST patients includes surgery, chemotherapy and radiotherapy, however, there is little evidence to support the benefit of the treatment options beyond surgery.

Goal

We aim to create and transfer biological discoveries into improved management of patients with MPNST.

Ongoing research

In a European multicentre study led by Prof Lothe we have in recent years identified prognostic biomarkers that can be used for stratification of high risk patients who could benefit from additional treatment after surgery and low risk patients who might be spared from the burdens of aggressive treatment. Current research is focusing on identification of predictive markers that can guide therapy choice for patients. We investigate cell culture model systems to identify specific vulnerabilities of the MPNST cells integrated with cancer drug screen data. The implementation of new drugs in clinical care is done in collaboration with Dr. Tormod Guren and others at the clinical trial unit at OUS.
