Abstract
BACKGROUND: This study was undertaken to determine the recurrence rate for open and endoscopic surgery and the clinical prognosis of this sinonasal tumor. METHODS: A systematic review of individual cases of sinonasal hemangiopericytoma was performed. A total of 97 articles were included in the study and reviewed to extract the relevant information about each case. RESULTS: In all, 194 cases of sinonasal hemangiopericytoma were identified. There were 53 recurrences (27.3%), 6 tumor-related deaths (3.1%), and 4 cases of metastases (2.1%). There was no significant difference between rate of recurrence for endoscopic or open resection (p = .06). Incomplete excision was the most important predictor of recurrence (odds ratio = 11.50, 95% confidence interval 3.76-36.82, p < .001). Radiotherapy may be advantageous in cases of incomplete surgical resection (p = .03). CONCLUSIONS: Complete excision is essential to minimize tumor recurrence and radiotherapy may decrease the rate of recurrence in the case of incomplete resection. Current evidence does not suggest that open resection is superior to endoscopic resection.
