Prospective Study of Children and Adolescents With Craniopharyngioma

Study Overview
=================
Brief Summary
-----------------
The present investigation is a prospective, multicenter study evaluating craniopharyngioma patients' prognoses following the various currently-practiced therapeutic strategies.Primary goals of the study are to establish quality standards and compare the various therapy strategies with respect to their effectiveness and impact on the quality of life of treated patients. A stratified randomization of two treatment arms will be conducted with respect to timing of postoperative irradiation for the subgroup of patients ≥5 years of age whose tumors are incompletely resected. The researchers will investigate whether an immediate, postoperative irradiation is superior to progression-contingent irradiation based on alterations to quality of life (PEDQOL) from the time randomization is initiated (3rd month post op) to 3 years after randomization. Progression-free survival and overall survival will be examined as closely-related subgoals.Postoperative data will be evaluated via a surveillance study for all complete resection patients as well as for those patients under 5 years of age regardless of their resection grade.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life | •Randomized investigation of children (≥ 5 years of age) and adolescent QoL changes (main goal assessment) following incomplete craniopharyngioma resections at primary diagnosis per QoL endpoint scores (PEDQOL physical functions domain) measured from 3rd month after surgery for 3 years after randomization; and the progression-free and total survival rates (subgoal assessments) relative to how these rates relate to postoperative irradiation timing (immediate postsurgery irradiation versus wait-and-see approach + progression-contingent irradiation of residual tumor). | 3 years after diagnosis | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of Progression or relapse | Compilation of applied therapy strategies for craniopharyngiomas in children and adolescents using data capture conforming to SIOP brain tumor groups Evaluation of patients' remission status following the various therapy strategies/modalities for craniopharyngiomas using data detection consistent with SIOP brain tumor groups Evaluation of the health status (ophthalmologic, neuropsychologic and endocrine conditions) and health-related QoL of children and adolescents following treatment of craniopharyngiomas using data capture conforming to SIOP brain tumor groups | 3 years after surgery |
