Repeated awake surgery and quality of life in patients with diffuse glioma: a systematic review and meta-analysis

Neurosurg Rev. 2023 Jun 29;46(1):156. doi: 10.1007/s10143-023-02073-6.


Diffuse gliomas significantly affect patients' daily lives. Because of the high risk of recurrence and anaplasic transformation, repeated surgery can be proposed in awake condition to prolongs overall survival by limiting and reducing residual tumour volume. However, oncological interest alone is no longer sufficient due to the consequent increase in median survival, and quality of life is becoming an important issue in clinical decision-making. This systematic review focuses on the effects of repeated surgery in awake condition on the quality of life of adults with diffuse glioma through three parameters: return to work, presence of postoperative neurocognitive disorders, and occurrence of epileptic seizures. A systematic review of the last 20 years was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) standards. Summarized data from selected studies were processed quantitatively, using a meta-analysis process, with the Review Manager 5.4 software. Five databases (PubMed, Web of Science, Science Direct, Dimensions, and Embase) were used. Fifteen articles were selected for qualitative analysis and 11 for meta-analysis. One hundred and fifty-one patients (85%) returned to an active socio-professional life after repeated surgery, and 78 (41%) presented neurocognitive disorders in the immediate postoperative period, only 3% (n = 4) of them suffering from permanent disorders. One hundred and forty-nine (78%) participants were free of epileptic seizure after repeated surgery. This systematic review of the literature highlights the benefit of repeated surgery on the quality of life of patients with adult diffuse glioma.
