The goal of this multicenter retrospective cohort study is to determine whether MRI-graded hypothalamic injury severity predicts growth-hormone deficiency (GHD) and neuropsychological morbidity in 500 children and adolescents (≤ 18 y) who underwent craniopharyngioma resection at six Chinese pediatric centers between 2013 and 2023 and were followed ≥ 2 years. The main questions it aims to answer are:
1. Does increasing hypothalamic injury grade (Grade 0 = uninvolved, Grade 1 = mild compression, Grade 2 = significant invasion) independently correlate with higher incidence of GHD, lower IGF-1 levels, greater height SDS decline, and increased need for recombinant human GH therapy?
2. Is higher injury grade associated with worse neuropsychological outcomes-lower IQ, impaired executive function, emotional disorders, and obesity-after adjustment for age, tumor size, and extent of resection?
Researchers compared the three injury-grade groups to quantify endocrine and neuro-behavioral outcomes and to catalog differentiated nursing needs (growth monitoring frequency, dietary-behavioral plans, psychological support intensity, comorbidity surveillance). Participants underwent pre- and post-operative MRI grading by blinded neuroradiologists, standardized endocrine stimulation tests, annual neuropsychological testing (WISC-IV, BRIEF, CBCL), and detailed nursing-documentation review; all data were analyzed with Spearman correlation, ANOVA, and multivariable logistic regression.
