BackgroundThis study was undertaken to determine the recurrence rate for open and endoscopic surgery and the clinical prognosis of this sinonasal tumor.MethodsA 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.ResultsIn 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).ConclusionsComplete 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. © 2012 Wiley Periodicals, Inc. Head Neck, 2013

BackgroundHuman papilloma virus (HPV) is emerging as the primary cause for some head and neck cancers. The objective of this study was to investigate the association between head and neck cancer (HNC) survival and socioeconomic status (SES) in Canada, and to investigate changes in the relationship between HNC survival and SES from 1992 to 2005.MethodsCases were drawn from the Canadian Cancer Registry (1992–2005), and were categorized into three subsites: oropharynx, oral cavity, and “other” (hypopharynx, larynx, and nasopharynx). Demographic and socioeconomic information were extracted from the Canadian Census of Population data for the study period, which included three census years: 1991, 1996 and 2001. We linked cases to income quintiles (InQs) according to patients’ postal codes.ResultsOverall survival, without controlling for smoking, for oropharyngeal cancer increased dramatically from 1992–2005 in Canada. This increase in survival for oropharynx cancer was eliminated by the introduction of controls for smoking. Survival for all head and neck cancer subsites was strongly correlated with SES, as measured by income quintile, with lower InQ’s having lower survival than higher. Lastly, the magnitude of the difference in survival between the highest and lowest income quintiles increased significantly over the time period studied for oropharynx cancer, but did not statistically significantly change for oral cavity cancer or other head and neck cancers.ConclusionsThese data confirm a significant impact of socioeconomic deprivation on overall survival for head and neck cancers in Canada, and may provide indirect evidence that HPV-positive head and neck cancers are more common in higher socioeconomic groups.
