Background:
Neuropsychological complications may impair the qualitative prognosis of patients with pediatric brain tumors. However, multifaceted evaluations cannot be conducted in all patients because they are time consuming and burdensome for patients. To resolve these issues, the Japan Children's Cancer Group developed the Neuropsychological Quick Assessment (NQA) as a screening tool for neuropsychological complications; however, its reliability and validity remain unverified. This observational pilot study evaluated the clinical usefulness of the NQA in patients with pediatric brain tumors.
Methods:
Patients with pediatric brain tumors treated at Kyoto University Hospital were enrolled. The NQA and functional outcomes (measure of neurocognitive function, motor coordination function, fatigue, and social behavior) were assessed. The NQA was divided into four component scales corresponding to these domains. Correlations between each NQA component scale score and functional outcomes were calculated. In addition, we calculated the area under the curve (AUC) to evaluate the diagnostic performance of the NQA.
Results:
Nineteen patients with a median age of 13.0 years were included. There were medium to large correlations between NQA component scores and most corresponding functional outcomes. The AUC [95% confidence interval] values for neurocognition, coordination, fatigue, and social behavior were 0.97 [0.93-1.00], 0.98 [0.94-1.00], 0.85 [0.68-1.00], and 0.90 [0.76-1.00], respectively, indicating high diagnostic accuracy.
Conclusions:
Each NQA component scale showed good correlation with corresponding functional outcomes. We conclude that the NQA is a simple and clinically useful screening tool for neuropsychological complications in patients with pediatric brain tumors.
