title: Craniopharyngioma: long-term consequences of a chronic disease.
abstract: Childhood-onset craniopharyngiomas (CP) are rare embryonal malformations of low-grade histological malignancy. Hypothalamic involvement and/or treatment-related lesions result in impaired physical and social functionality and severe neuroendocrine sequelae. Quality of life in CP with hypothalamic involvement is impaired by severe obesity, physical fatigue, reduced motivation, dyspnea, diarrhea, and non-optimal psychosocial development. 567 CI patients have been recruited between 1998 and 2010 in the German Craniopharyngioma Registry. Only 5 of 567 patients (<1%) presented without confirmed signs of relapse/progression, visual impairment, and endocrine deficiencies during longitudinal follow-up of more than 5 years. Hypothalamic obesity in CP is associated with a severe increase in BMI during the early post-operative period. Patients with CP involving hypothalamic structures show reduced 10-years overall survival, whereas overall and progression-free survival rates are not related to the degree of surgical resection. Accordingly, gross-total resection should be avoided in cases of hypothalamic involvement to prevent further hypothalamic damage. As surgical expertise has been shown to have impact on postoperative morbidity, medical societies should establish criteria of adequate professional expertise for the treatment of CP. Based on these criteria, health authorities should organize the certification of centers of excellence authorized for treatment and care of patients with this chronic disease.
