Management of recurrent malignant glioma--neurosurgical strategies

There is currently no standard for neurosurgical interventions in patients with recurrent high grade gliomas. An individualized approach is recommended as well for decision-making as for planning an intervention with resection of the outmost possible amount of tumor tissue while preserving neurological function and thus quality of life. Recent technical developments of imaging and of neuronavigation and visualization of tumor tissue with in vivo fluorescence with 5-Ala have proved helpful in improving symptoms and prolonging survival times also for patients with recurrent malignant gliomas.
