Maximizing tumor resection while preserving eloquent areas

Clinical challenge

Finding the balance between preserving functional areas and extending resection during brain tumor surgery is a challenge even for experienced neurosurgeons. Therefore, intraoperative information is critical to be able to make the right decision at the right time.

Andreas Raabe, MD

The main question is: Is there still tumor? […] And here maximum safe resection is the principle because we cannot cure them by surgery and still the extent of resection correlates with survival. […] It is not only the extent of resection but also the maintenance and the preservation of function.

Clinical challenges in brain tumor treatment

  • Visualization of fluorescence

    See

    Precise identification of tumor areas is crucial, particularly in the case of infiltrative gliomas.1
    Therefore, the foundation of a safe surgery is the multifaceted visualization of the target region and the surrounding eloquent tissue.2,3

  • Check brain tumor

    Check

    In vivo cellular imaging in real-time remains a challenge in neurosurgery. It is practically impossible to remove every glioma cell surgically. Increasing the precision of glioma removal with more accurate margin delineation predicts better treatment outcomes.4,5

  • Treating brain tumors

    Treat

    Radiotherapy in the brain is normally done several weeks after the surgical tumor removal which enables potential residual tumor cells to regrow by then.6 In addition, conventional radiotherapy today has a certain risk of irradiation scattering which can lead to radiation necrosis of eloquent tissue and result in neurocognitive failures.7,8

ZEISS Tumor Workflow

The ZEISS Tumor Workflow9 combines three leading technologies from ZEISS: Advanced surgical visualization, in vivo pathology, and intraoperative radiotherapy. Thereby, ZEISS supports multidisciplinary teams, including neurosurgeons, neuropathologists, and radiation oncologists, over several steps of the surgical workflow in delivering brain tumor treatment.
