Background: Hemangioblastomas (HBs) are rare and understudied. The impact of age on clinical features, optimal treatment, and postoperative outcome in HBs has not been systemically studied.
Materials and methods: We performed an institutional study in the West China Hospital, including patients diagnosed with hemangioblastomas between October 2011 and October 2016. Clinical data and surgical outcomes were compared among three different age groups (0-20, 21-59, and ≥ 60 years). We also studied surgical prognostic factors.
Results: 187 patients (102 males and 85 females) were identified. HBs in spinal locations were more prevalent in children and adolescents, while the most common site in young and old-age adults was the cerebellum (P = 0.023). Risk of Von Hippel-Lindau syndrome (VHL) was negatively correlated with patient age (P = 0.003). 47.6 % of patients aged 0-20, 23 % of patients aged 21-59, and 6.45 % of patients aged ≥60 years were diagnosed with VHL. Older aged patients had a significantly lower risk of VHL and had a lower tumor recurrence rate. Surgical resection was an adequate and sufficient procedure in all age groups with a favorable surgical outcome (P = 0.823). Solid tumor, VHL disease, and localization in the brainstem were associated with poor outcome in patients with hemangioblastomas.
Conclusions: Our study showed that HBs in elderly patients were mostly included in the cerebellum and had a solid configuration and large size, while HBs in children were mainly localized in the spinal cord. VHL disease was more common in children and adolescents but rare in patients older than 60 years. The present study found no excess surgical mortality and risks for HBs in elderly patients or children than in younger adults.
