NCT05786144

Brief Summary

In standard of care regularly planned surgery, tissue will be obtained from patients who are suspicious for having vestibular Schwannoma (on MRI). The tissue that remains after the pathologist gathered sufficient for analysis, the remaining tissue is used for creating tumour stem cell organoids.
