To the Editor,

With great interest we have read the meta-analysis by Ng et al. [1] on ‘Effects of surgery on neurocognitive function in patients with glioma’ which was recently published in this journal. The authors aimed to identify the tests that are commonly used for neuropsychological assessment in glioma patients. Furthermore, they aimed to quantify changes in cognitive function in glioma patients on the short and long term after surgery. Based on 11 studies that were included in the meta-analysis, it was concluded that surgery in glioma patients confers a benefit for performance on all cognitive domains that were assessed, except for executive functions which deteriorated after surgery. In addition, the authors underscore the need for more prospective and longitudinal studies assessing the effects of surgery on cognitive functioning in patients with glioma, and recommend using a standardized neuropsychological assessment battery in doing so.

Although this meta-analysis draws...
