RESUMO
INTRODUCTION: Hypothalamic invasion in pediatric patients with craniopharyngioma negatively influences clinical outcomes. It has been shown that radiologic classification of hypothalamic invasion can effectively predict surgical strategies to minimize postoperative comorbidities in pediatric patients. However, no comparative analysis has been performed in adult patients with craniopharyngioma. This study implements the previously established radiologic classification to characterize postoperative morbidity, surgical outcome, and distress in adult patients with craniopharyngioma. METHODS: Electronic medical records of 22 adult patients with craniopharyngioma were used to analyze patient demographics, surgical data, endocrinologic and ophthalmologic status, and histopathology in a retrospective single-center study. Questionnaires regarding postoperative distress (National Comprehensive Cancer Network Distress Thermometer and Problem List), comorbidities (Charlson Comorbidity Index), employment status, and need for supportive care were distributed. Magnetic resonance imaging scans were categorized according to Puget et al. RESULTS: Patients with hypothalamic involvement show significantly higher rates of postoperative diabetes insipidus and higher scores on the National Comprehensive Cancer Network Distress Thermometer. This significant difference was lost when considering postoperative Puget grades. Puget grades 1 and 2 were found to be associated with the use of a subfrontal surgical approach (hazard ratio, 4.080; confidence interval, 1.153-14.431; P = 0.029). CONCLUSIONS: Our results point toward a possible predictive role of preoperative hypothalamic invasion for postoperative diabetes insipidus as well as higher perceived levels of distress after surgery, which may be established in larger patient cohorts. Furthermore, a subfrontal surgical approach seems to be predicted by tumors with hypothalamic invasion. In this case, preoperative magnetic resonance imaging grading may help guide the planning of an optimal surgical strategy for adults with craniopharyngioma to reduce postoperative morbidity.
