ABSTRACT
Central nervous system (CNS)-directed chemotherapy is delivered for the treatment of childhood acute lymphoblastic leukaemia (ALL). Figurative language deficits have been described in children following CNS-directed chemotherapy; however, comprehensive analysis of figurative interpretation errors, potentially providing clinical utility to assist with intervention planning, has never been performed. The present study aimed to compare the figurative language skills of seven children treated with CNS-directed chemotherapy for ALL before the age of 6 years (mean age at diagnosis 3 years 10 months) and a matched control group of children, using the Test of Language Competence-Expanded Edition (TLC-E) Figurative Language sub-test. It was hypothesised that the children treated with CNS-directed chemotherapy would demonstrate a decreased performance in and an alternative method of interpreting figurative language. The results suggest no negative effects of CNS-directed chemotherapy on figurative language. There were no statistically significant differences between groups for TLC-E Figurative Language sub-test composite scores and picture component errors, nor were there clinically significant differences observed from descriptive comparisons of individual case data and error analysis. As these skills continue to emerge beyond childhood, the need to monitor skill development in ALL survivors beyond childhood is highlighted.
