Survival Outcome of XXXX Arising from Sinonasal @entity1179 .

@entity5 @entity1179 @entity1 @entity957
BACKGROUND: Sinonasal @entity1179 ( @entity1179 ) is a rare @entity5 of the nasal cavities and paranasal sinuses. It is destructive or bone-remodeling, tends to recur after surgical resection, and has a significant malignant potential. The present study aimed to perform a retrospective analysis of @entity1 with @entity957 ( @entity957 ) arising from @entity1179 , including characteristics, survival outcome, and predictors of associated @entity5 . METHODS: The medical records of 213 @entity1 diagnosed with @entity1179 from January 1970 to January 2014 were retrospectively reviewed. Eighty-seven @entity1 were diagnosed with @entity957 / @entity1179 ; their clinical characteristics, treatments, and survival outcomes were analyzed. RESULTS: Of the 87 @entity1 with @entity957 / @entity1179 , the 5- and 10-year overall survival outcomes were 39.6% and 31.8%, respectively. Twenty-nine of these @entity1 received surgery and 58 received combined surgery and radiation. Of the @entity1 with stages III-IV, the 5-year survival rate was 30.7% for those treated with surgery only and 39.9% for those given the combination treatment (P = 0.849). Factors associated with significantly poor prognosis were @entity5 , or with cranial base and orbit invasion. Age, synchronous or @entity5 , and pathological stage were independent risk factors for mortality, shown by multivariate analysis. CONCLUSION: @entity1 with @entity957 / @entity1179 had low overall survival outcomes. Advanced age, stage, and @entity5 are the main factors affecting prognosis. Treatment planning should consider high-risk factors to improve survival outcome.
