Narrative skills of children treated for brain tumours: The impact of tumour and treatment related variables on microstructure and macrostructure

The narrative skills of children with brain tumours were examined. Influence of tumour location, radiotherapy, time post-treatment and presence of hydrocephalus was also investigated, as well as associations between narrative and language abilities.Seventeen children (aged 5;6-14;11) treated for brain tumour and their matched controls completed a narrative assessment and comprehensive language testing. Audio recorded narratives were analysed for microstructure and macrostructure elements. Between-group comparisons were conducted. Narrative elements were explored in association with tumour and treatment-related variables. Correlation analysis examined relationships between narrative scores and language test performance.While significant differences were not found between two groups of children across narrative elements, sub-group comparisons revealed marginal differences in macrostructure related to tumour location and hydrocephalus. Children treated with methods other than radiotherapy showed a significant increase in number of mazes in their narratives compared to children who received radiotherapy. Strong positive correlations also existed between narrative elements and language performance.Preliminary findings highlight the importance of investigating narrative abilities as part of a comprehensive language assessment. Macrostructure should be routinely examined where children are diagnosed with either posterior fossa tumour or hydrocephalus or have undergone surgery and/or chemotherapy for brain tumour.
