Abstract
Purpose
We aimed to determine whether extent of morphological brain injury in pediatric cerebellar tumor survivors correlates with neurocognitive function and health-related quality of life (HrQoL).
Methods
Seventeen cerebellar pilocytic astrocytoma (cPA) and 17 medulloblastoma (MB) survivors were examined for HrQoL, intelligence using the German version of the WISC-III, attention, working memory, and visual motor coordination. MRI scans were analyzed for extent of posterior fossa brain tissue loss.
Results
We found significant correlations between amount and extent morphological brain lesions of pediatric cerebellar tumor survivors and several cognitive impairments including intelligence and attention in both patient groups. These were in total more pronounced in MB patients when compared to cPA patients. Still, function loss and brain lesions detected on conventional MRI did not influence HrQoL.
Conclusions
These findings support the notion that long-term neurocognitive deficits of pediatric posterior fossa tumor survivors significantly correlate with brain tissue damage. The cerebellum plays a role in regulating higher-order functions. On the contrary, the extent brain injury is not detected by HrQoL assessment.
