The Meningioma Research Group are conducting a range of clinical and laboratory studies related to the natural history, biological behaviour, imaging characteristics, and long-term outcomes of all grades of meningioma. Meningiomas are one of the most common primary tumours of the central nervous system and have the potential to cause both morbidity and mortality. Understanding the behaviour, associations, and clinical outcomes of these tumours will improve patient care, refine surgical techniques, and other related disciplines such as neuroradiology and neuropathology.
- Epileptogenesis in meningioma
We are collaborating with the University of Liverpool and other Neurosurgical Units around the UK in the multi-centre RCT ‘STOP ‘EM’, investigating placebo-controlled levetiracetam prophylaxis in seizure-naïve patients undergoing elective meningioma surgery. Primary clinical outcome measurements include seizure incidence within the first post-operative year and patient-reported quality of life. Part of the study will also involve taking blood samples from patients in the perioperative period and measuring blood plasma cytokines. As there is emerging evidence of the role of inflammation in seizures, including in epilepsy, TBI, and brain tumours, it is envisaged that this work could risk stratify patients who are likely to have seizures and may need closer clinical follow-up or seizure prophylaxis. There may also be therapeutic implications for confirming and understanding an inflammatory basis to seizures in meningioma.
- Novel imaging methods for pre-operative planning
Recent improvements in the understanding of meningioma biology, including the discovery and utilisation of the somatostatin receptor have enabled somatostatin-analogue PET ligands to be developed that may have additional benefit in identifying the extent of meningioma than conventional imaging alone. We are studying the utility of Ga-DOTATOC PET/MRI in identifying the extent of meningioma-associated dural tails and comparing this with pathological analysis of somatostatin receptor antibody immunohistochemistry. This work may improve our ability to safely resect maximal tumour-involved dura and minimise risk of recurrence.
- Outcome assessment following meningioma resection
Patients who have low-grade meningiomas resected may have normal lifespans. Most clinical follow-up ceases within a few years after surgery therefore we understand little about the long-term outcomes patients are experiencing, which may include disability due to motor deficit, seizures, or other post-operative problems. Health-related quality of life outcomes are an important metric in ensuring clinical care is responsive to patient needs and is managing post-operative problems appropriately.
