Résumé
OBJECTIVE: Intradural spinal hemangioblastoma are infrequent, vascular, pathologically benign tumors occurring either sporadically or in association with von Hippel-Lindau disease along the neural axis. Described in fewer than 1,000 cases, literature is variable with respect to epidemiological factors associated with spinal hemangioblastoma and their treatment. The objective of this study was to evaluate the epidemiology of intradural spinal hemangioblastoma with the Surveillance, Epidemiology and End Results (SEER) database while also presenting an illustrative case. METHODS: The SEER database was queried for cases of spinal hemangioblastoma between 2000 and 2010 with the use of SEER*Stat software. Incidence was evaluated as a function of age, sex and race. Survival was evaluated with the Cox proportionate hazards ratio using IBM SPSS software evaluating age, sex, location, treatment modality, pathology and number of primaries (p = 0.05). Descriptive statistics of the same factors were also calculated. The case of a 43-year-old patient with a surgical upper cervical intramedullary hemangioblastoma is also presented. RESULTS: In the data set between 2000 and 2010, there were 133 cases with an age-adjusted incidence of 0.014 (0.012-0.017) per 100,000 to the standard USA population. Hemangioblastoma was the tenth most common intradural spinal tumor type representing 2.1% (133 of 6,156) of all spinal tumors. There was no difference in incidence between men and women with an female:male rate ratio of 1.05 (0.73-1.50) with p = 0.86. The average age of patients was 48.0 (45.2-50.9) years, and a lower incidence was noted in patients <15 years compared to all other age groups (p < 0.05). There was no difference in incidence amongst the different races. Treatment included surgical resection in 106 (79.7%) cases, radiation with surgery in 7 (5.3%) cases, and radiation alone was used in only 1 (0.8%) case, and no treatment was performed in 17 (12.8%) cases. Mortality was noted in 12 (9%) cases, and median survival of 27.5 months (range 1-66 months) over the 10-year period. Mortality was attributable to the malignancy in 3 (2%) cases. There was no statistically significant different in Cox hazard ratios for mortality for sex, race, treatment modality, pathology or number of primaries. CONCLUSIONS: Spinal hemangioblastoma represent a small fraction of primary intradural spinal tumors, and this study did not identify any difference in incidence between genders. Surgical treatment alone was the most common treatment modality. Overall prognosis is good, with 9% observed mortality over the 10-year period, with 2% mortality attributable to the malignancy.
