Abstract
Invasiveness is the major cause of death in patients bearing a brain tumour. The invasiveness or infiltrative capacity of a primary brain tumour has a prognostic value for the evaluation of the process in vivo. So a model to imitate invasion might give information on the in vivo behaviour and outcome of the disease for the individual patient. The developed in vitro model represents an assay in which the patients’ brain tumour-derived cells are confronted with connective tissue from the patient himself, i.e. an autologous system to evaluate the individual behaviour of the tumour, in contrast to other invasion models. The test can be applied with tumour-derived material collected by a stereotactic biopsy.
