Clinical Situation, Therapy, and Follow-Up of Adult Craniopharyngioma.

CONTEXT: Craniopharyngioma is a rare neoplastic entity of the central nervous system. Childhood-onset craniopharyngioma is the subject of frequent research whereas the information on adult-onset craniopharyngioma is scarce.

OBJECTIVE

The objective of this study was to examine the level of daily impairment in adult patients suffering from craniopharyngioma.

DESIGN

Noninterventional patient registry indexed as PV4842 with the local ethics committee.

SETTING

The study is set in a hospitalized and ambulatory setting.

PATIENTS: 148 patients with adult-onset craniopharyngioma were recruited from 8 centers, 22 prospectively and 126 retrospectively. Mean follow-up was 31 months.

INTERVENTIONS: No interventions performed.

MAIN OUTCOME MEASURES: Complications, symptoms, body mass index (BMI), and quality of life (QoL; EORTC QLQ C30 and BN20) were recorded preoperatively and at follow-up. The hypotheses tested were generated after data collection.

RESULTS

Complications were more frequent after transcranial than transsphenoidal approaches (31 % vs. 11%; P < 0.01). Preoperative obesity was present in 0% papillary and in 38% of all adamantinomatous craniopharyngiomas (P = 0.05), and diabetes insipidus was more frequent for papillary craniopharyngioma (36.8% vs. 16,7%; P < 0.05). Hormone deficits at follow-up were reduced in 16.9%, equal in 31.4%, and increased in 63.6% (P < 0.001). BMI increased from 28.7 ± 7.4 kg/m2 before surgery to 30.2 ± 7.4 kg/m2 at follow-up (P < 0.001). In QoL, a decrease of future uncertainty (62.5 vs. 36.8; P = 0.02) and visual disorders (38.9 vs. 12.0; P = 0.01) were observed in the prospective collective after surgery.

CONCLUSIONS

Adult craniopharyngioma is associated with a complex sociological and psychological burden and hypothalamic dysfunction, warranting further investigation and emphasizing the need for a wider treatment approach.
